OPINION
Justice McCAFFERY.
The issue before the Court in this case concerns the qualifications an expert witness must possess in order to testify regarding the standard of care in a medical professional liability case against a physician, pursuant to the Medical Care Availability and Reduction of Error (“MCARE”) Act.1
Joseph Vicari (“Appellee”) brought a medical professional liability claim against Joseph R. Spiegel, M.D.; Pramila Rani Anne, M.D.; and Jefferson Radiation Oncology Associates (collectively “Appellants”) after Appellee’s wife, Barbara Vicari, died from metastatic tongue cancer on April 1, 2002, at 39 years of age.2 Dr. Spiegel, an otolaryngologist, had surgically removed Mrs. Vicari’s tumor on March 6, 2001, and then had continued to serve as the primary physician responsible for management of her cancer. Dr. Anne, a radiation oncologist, had treated Mrs. Vicari post-surgically with a course of radiation therapy. The gravamen of Appellee’s malpractice claim against these two physicians was that they had never discussed with Mrs. Vicari the possibility of post-surgical followup treatment with chemotherapy, nor referred her to a medical oncologist for such a discussion. In Appellee’s view, this omission was particularly egregious because the surgical pathology report on the specimens removed during Mrs. Vicari’s [384]*384surgery suggested that she had a high risk of tumor recurrence and metastasis.3
At a jury trial presided over by the Honorable Esther R. Sylvester, Appellee presented testimony from two expert witnesses: Ronald H. Blum, M.D., a medical oncologist, and Peter Berman, M.D., an otolaryngologist. Appellee also presented excerpts from Dr. Spiegel’s deposition testimony, as well as testimony by Appellee himself and the Vicaris’ two children. Appellee then rested his case just prior to the lunch recess on May 2, 2006.
Immediately after the recess, Appellee’s counsel made an oral motion to reopen his case because he was unsure whether Dr. Berman had used the words “to a reasonable degree of medical certainty” during his expert opinion testimony. Notes of Testimony (“N.T.”), 5/2/06, at 101-02. Appellants’ counsel objected to Appellee’s motion to reopen, and following argument, the court denied Appellee’s motion and struck Dr. Berman’s testimony. Id. at 111, 121.
Counsel for Dr. Spiegel then made an oral motion for compulsory nonsuit, arguing that Dr. Blum was not competent to testify against Dr. Spiegel or Dr. Anne as to the applicable standard of care, because Dr. Blum was not board certified in the same field as either of the defendant physicians.4 Id. at 112-13, 127. Counsel further contended that the lack of common board certification between Dr. Blum and either Dr. Spiegel or Dr. Anne was “a threshold question which is kind of a black and white issue” and a “fatal flaw in the case.” Id. at 113. Counsel for Dr. Anne joined in the oral motion. Id. at 120. Following argument, the trial court accepted Appellants’ [385]*385contention that Dr. Blum was not competent to testify and struck his testimony as well. With the testimony of both experts stricken, the trial court granted Appellants’ motion for nonsuit.5 Id. at 131. Appellee’s motion to remove the nonsuit was denied, and the trial court entered judgment in favor of Appellants.
Appellee appealed to the Superior Court, arguing that the trial court had abused its discretion both by striking Dr. Berman’s testimony because it was allegedly not rendered to the requisite degree of medical certainty, as well as by striking Dr. Blum’s testimony because, under the MOARE Act, he allegedly did not qualify as an expert witness as to standard of care. Vicari v. Spiegel, 936 A.2d 503, 508-09 (Pa.Super.2007).6 The Superior Court reversed and remanded for a new trial. Id. at 515. With regard to Dr. Berman’s opinion testimony that Appellants’ failure to refer Mrs. Vicari for chemotherapy [386]*386had increased her risk for metastasis, the Superior Court held that, taken in its entirety, the testimony had been rendered to a reasonable degree of medical certainty. Id. at 511. With regard to Dr. Blum, the Superior Court concluded that, under the MCARE Act, he was indeed qualified to testify that Appellants had deviated from the applicable standard of care by failing to discuss with Mrs. Vicari the option of chemotherapy and failing to refer her to a medical oncologist for this purpose. Id. at 515.
Appellants then sought allowance for appeal from this Court, challenging the propriety of the Superior Court’s holding that the trial court had committed error when it had found Dr. Blum unqualified to testify against them.7 We granted allowance of appeal on the following issue:
Whether [Appellee’s] medical oncology expert [Dr. Blum] was qualified to render standard of care opinions against an otolaryngologist and radiation oncologist under Section 512 of the Medical Care Availability and Reduction of Error Act. 40 P.S. § 1303.512.
Vicari v. Spiegel, 601 Pa. 375, 973 A.2d 408-09 (2009).
With passage of the MCARE Act, the General Assembly created a more stringent standard for admissibility of medical expert testimony in a medical malpractice action by the imposition of specific additional requirements not present in the common law standard. Gbur v. Golio, 600 Pa. 57, 963 A.2d 443, 452 (2009) (Opinion Announcing the Judgment of the Court); id. at 464 (Greenspan, J., concurring) (agreeing that, with the MCARE Act, the General Assembly raised the standards for an expert witness testifying to a physician’s standard of care, but also noting that the statute permitted waiver of certain requirements under appropriate circumstances); Wexler v. Hecht, 593 Pa. 118, 928 A.2d 973, 986 (2007) (Castille, J., dissenting). The MCARE Act’s provisions as to the requisite qualifications for an expert witness testifying in a medical malpractice action against a physician are [387]*387found in Section 512, which provides, in relevant part, as follows:
(a) General rule. — No person shall be competent to offer an expert medical opinion in a medical professional liability-action against a physician unless that person possesses sufficient education, training, knowledge and experience to provide credible, competent testimony and fulfills the additional qualifications set forth in this section as applicable.
(b) Medical testimony. — An expert testifying on a medical matter, including the standard of care, risks and alternatives, causation and the nature and extent of the injury, must meet the following qualifications:
(1) Possess an unrestricted physician’s license to practice medicine in any state or the District of Columbia.
(2) Be engaged in or retired within the previous five years from active clinical practice or teaching.
(c) Standard of care.

Justice McCAFFERY.
The issue before the Court in this case concerns the qualifications an expert witness must possess in order to testify regarding the standard of care in a medical professional liability case against a physician, pursuant to the Medical Care Availability and Reduction of Error (“MCARE”) Act.1

Whether [Appellee’s] medical oncology expert [Dr. Blum] was qualified to render standard of care opinions against an otolaryngologist and radiation oncologist under Section 512 of the Medical Care Availability and Reduction of Error Act. 40 P.S. § 1303.512.
Vicari v. Spiegel, 601 Pa. 375, 973 A.2d 408-09 (2009).
With passage of the MCARE Act, the General Assembly created a more stringent standard for admissibility of medical expert testimony in a medical malpractice action by the imposition of specific additional requirements not present in the common law standard. Gbur v. Golio, 600 Pa. 57, 963 A.2d 443, 452 (2009) (Opinion Announcing the Judgment of the Court); id. at 464 (Greenspan, J., concurring) (agreeing that, with the MCARE Act, the General Assembly raised the standards for an expert witness testifying to a physician’s standard of care, but also noting that the statute permitted waiver of certain requirements under appropriate circumstances); Wexler v. Hecht, 593 Pa. 118, 928 A.2d 973, 986 (2007) (Castille, J., dissenting). The MCARE Act’s provisions as to the requisite qualifications for an expert witness testifying in a medical malpractice action against a physician are [387]*387found in Section 512, which provides, in relevant part, as follows:
(a) General rule. — No person shall be competent to offer an expert medical opinion in a medical professional liability-action against a physician unless that person possesses sufficient education, training, knowledge and experience to provide credible, competent testimony and fulfills the additional qualifications set forth in this section as applicable.
(b) Medical testimony. — An expert testifying on a medical matter, including the standard of care, risks and alternatives, causation and the nature and extent of the injury, must meet the following qualifications:
(1) Possess an unrestricted physician’s license to practice medicine in any state or the District of Columbia.
(2) Be engaged in or retired within the previous five years from active clinical practice or teaching.
(c) Standard of care. — In addition to the requirements set forth in subsections (a) and (b), an expert testifying as to a physician’s standard of care also must meet the following qualifications:
(1) Be substantially familiar with the applicable standard of care for the specific care at issue as of the time of the alleged breach of the standard of care.
(2) Practice in the same subspecialty as the defendant physician or in a subspecialty which has a substantially similar standard of care for the specific care at issue, except as provided in subsection (d) or (e).
(3) In the event the defendant physician is certified by an approved board, be board certified by the same or a similar approved board, except as provided in subsection (e).
(e) Otherwise adequate training, experience and knowledge. — A court may waive the same specialty and board certification requirements for an expert testifying as to a standard of care if the court determines that the expert [388]*388possesses sufficient training, experience and knowledge to provide the testimony as a result of active involvement in or full-time teaching of medicine in the applicable subspecialty or a related field of medicine within the previous five-year time period.
40 P.S. § 1303.512.
Thus, pursuant to Section 512, to testify on a medical matter in a medical malpractice action against a defendant physician, an expert witness must be a licensed and active, or a recently retired, physician. In addition, in order to render an opinion as to the applicable standard of care, the expert witness must be substantially familiar with the standard of care for the specific care in question. Furthermore, the expert witness must practice in the same subspecialty as the defendant physician, or in a subspecialty with a substantially similar standard of care for the specific care at issue (“same specialty requirement”). Finally, if the defendant physician is board certified, the expert witness must be board certified by the same or a similar board (“same board certification requirement”). Importantly, the expert witness must meet all of these statutory requirements in order to be competent to testify. However, there is an exception to the same specialty and same board-certification requirements: if a court finds that an expert witness has sufficient training, experience, and knowledge to testify as to the applicable standard of care, as a result of active involvement in the defendant physician’s subspecialty or in a related field of medicine, then the court may waive the same specialty and same board certification requirements.
This Court has directly addressed the requirements of Section 512 only infrequently. In Wexler, supra, we held that a podiatrist was not competent to testify as an expert witness in a medical malpractice action against an orthopedic surgeon because a podiatrist does not possess an unrestricted physician’s license, as required under subsection 512(b)(1). Wexler, supra at 974, 981-82.
[389]*389More recently, in Gbur, supra, three of six participating members of this Court concluded that a radiation oncologist was competent to testify against a urologist regarding the standard of care for a prostate cancer patient. Id. at 463-65 (Greenspan, J., concurring). Relying on the exception set forth in subsection 512(e), the concurring justices concluded that the radiation oncologist was eminently qualified to testify in the action as a result of his active involvement in the diagnosis and treatment of numerous patients with prostate cancer. Id. at 464-65. The three other justices who participated in Gbur did not reach the merits of the expert witness’s qualifications under the MCARE Act, but rather concluded that the issue had not been properly preserved and thus was waived. Nonetheless, the Court did express, albeit in dicta, its opinion concerning the application of subsection 512(e), particularly with regard to the meaning of the phrase “related field of medicine” as used in that subsection. See discussion in text, infra.8
[390]*390Here, the legal issue presented is the same as the underlying legal issue in Gbur: how to interpret the limitations and exception set forth in Section 512 of the MCARE Act regarding medical expert testimony against a physician as to standard of care when the proffered or testifying expert practices in a different subspecialty and/or is board certified by a different board than the defendant physician. This is a question of law, and accordingly our standard of review is de novo and our scope of review is plenary. Mazur v. Trinity Area School District, 599 Pa. 232, 961 A.2d 96, 101 (2008). We must ascertain and effectuate the intent of the General Assembly based upon a reading of the entire statute. Penn Jersey Advance, Inc. v. Grim, 599 Pa. 534, 962 A.2d 632, 635-36 (2009).
The trial court here appears to have based its ruling that Dr. Blum was incompetent to testify as to standard of care against Drs. Spiegel and Anne on the misconception that the MCARE Act mandates that, if the defendant physician is board certified, then the testifying expert must be board certified by the same board. There was no dispute that Dr. Blum, Dr. Spiegel, and Dr. Anne were all board certified by different boards. See infra. There is also no dispute that certification by the same or a similar board is the general rule promulgated in subsection 512(c)(3); however, the final phrase of this subsection provides for an exception, set forth in subsection 512(e), which the trial court did not appear to recognize. Under the exception, a court may waive the same board certification and same specialty requirements if the court determines that the expert possesses “sufficient training, experience and knowledge” to testify as to standard of care “as a result of active involvement in ... medicine in the applicable subspecialty or a related field of medicine.” 40 P.S. § 1303.512(e).
[391]*391Pursuant to the exception set forth in subsection 512(e), Dr. Blum’s unchallenged and undisputed professional qualifications and activities established that he was competent to testify against Drs. Spiegel and Anne as to the specific care at issue. It is of utmost importance to stress that such a competency determination can be made only after delineation of precisely what is the specific care at issue and after consideration of what testimony the expert will render. With this caveat in mind, and to be absolutely clear, we reiterate what this case is not about: There is no allegation that Dr. Spiegel breached the applicable standard of care in his performance of Mrs. Vicari’s surgery to resect the tumor, nor is there any allegation that Dr. Anne breached the applicable standard of care in her administration of radiation therapy to Mrs. Vicari. The sole issue is whether the standard of care applicable to Drs. Spiegel and Anne included the requirement to offer Mrs. Vicari the option of follow-up chemotherapy and to refer her to a medical oncologist for this purpose. Concerning this narrow question, we conclude that Dr. Blum was well qualified, under Section 512 of the MCARE Act, to testify as to his opinion even though he was board certified by a different board and practiced in a different subspecialty than the defendant physicians.
The exception set forth in subsection 512(e) provides that the court may waive same board and same specialty requirements if the proposed expert has sufficient training, experience, and knowledge to testify as a result of active involvement in a field of medicine “related” to the subspecialty of the defendant physician. The statute does not define the term “related field of medicine.” However, in the Opinion Announcing the Judgment of the Court in Gbur, Justice Saylor did consider, albeit in dicta, the meaning of this phrase in the context of subsection 512(e), and suggested that it “must mean more than fields of medicine which are ‘related’ in the most generic sense of the word, since Section 512(e) serves as a component of reform legislation designed to meaningfully enhance the standards governing the admissibility of expert testimony in medical professional liability cases.” Gbur, su[392]*392pra at 459 (Opinion Announcing the Judgment of the Court). Justice Saylor continued his interpretation as follows: “[T]he statute should be read to require a close enough relation between the overall training, experience, and practices of the expert and that of the defendant-physician to assure the witness’s expertise would necessarily extend to standards of care pertaining in the defendant-physician’s field.” Id. Here, we expressly adopt the above two statements from Gbur’s opinion announcing the judgment of the court as explicative of subsection 512(e).
In addition, we further explicitly hold that the “relatedness” of one field of medicine to another for purposes of subsection 512(e) cannot be established in a broad and general sense that will henceforth be applicable to all situations and all claims. Rather, the “relatedness” of one field of medicine to another, under subsection 512(e), can only be assessed with regard to the specific care at issue. Two fields of medicine may be “related” with respect to certain specific issues of care, but unrelated with respect to other specific issues of care. Determining whether one field of medicine is “related” to another with respect to a specific issue of care is likely to require a supporting evidentiary record and questioning of the proffered expert during voir dire. This interpretation of “related field of medicine” is most compatible with the text of subsection 512(e) as a whole, which sets forth an exception to the formal same specialty and same board certification rules for experts otherwise qualified to testify.9
[393]*393Here, there was no question that Dr. Blum, Dr. Spiegel, and Dr. Anne were certified by different boards and practiced in different specialties. Dr. Blum was board certified in internal medicine •with a subspecialty in medical oncology by the American Board of Internal Medicine. Dr. Spiegel was board certified in otolaryngology by the American Board of Otolaryngology. Dr. Anne was board certified in radiation oncology by the American Board of Radiology. In a general sense, these fields of medicine would not appear to be “related,” but the evidentiary record established that with regard to the specific care at issue, i.e., whether Mrs. Vicari should have been given the option of chemotherapy and a referral to a medical oncologist, these fields surely were “related” for purposes of subsection 512(e) in this case.
This relatedness ultimately springs from the complexities and realities of modern cancer therapy, during which an individual cancer patient often obtains different treatments under the auspices of several different specialties of medical practice, and different specialists often treat the patient in a sequential but coordinated manner. Given the complex and multi-disciplinary nature of many treatment regimens, consensus decisions as to the care of individual cancer patients are often reached by a multi-disciplinary panel of physicians known as a “tumor board,” the composition and activities of which were explored at trial. As Dr. Blum’s undisputed testimony made clear, patients in accredited cancer centers are routinely reviewed by a “tumor board,” which consists of physicians from a variety of specialties and subspecialties, including medicine, surgery, diagnostic radiology, radiation oncology, and pathology. N.T., 5/1/06, at 68, 103. Dr. Blum explained that, at the tumor board conference, “there’s a full discussion of the various factors that go into decision making” and “then decisions are made” concerning the cancer patient. Id. at 68. Dr. Spiegel, in his deposition testimony read in part at trial, stated that he had presented Mrs. Vicari’s case to the “head and neck tumor board, which is a joint discussion of [394]*394multiple physicians that take care of head and neck cancer, including radiation oncologists and medical oncologists to assure that the consensus of opinion is available to the patient.” 10 N.T., 5/2/06, at 5 (emphasis added). Thus, for the specific care at issue here — whether, following Mrs. Vicari’s surgery, which was conducted by an otolaryngologist, and her radiation therapy, which was administered by a radiation oncologist, she should have been offered chemotherapy and accordingly referred to a medical oncologist — we conclude that medical oncology is a “related field of medicine” to otolaryngology and radiation oncology, pursuant to subsection 512(e).
The conclusion that Dr. Blum, as a practicing medical oncologist, was actively involved in a related field of medicine to that of Drs. Spiegel and Anne does not, of course, end the inquiry required in subsection 512(e). The question remains whether Dr. Blum, because of his active involvement in medical oncology, had sufficient training, experience, and knowledge to testify as to the specific standard of care at issue. We conclude that he unquestionably meets this statutory standard.
As a medical oncologist, Dr. Blum had maintained a clinical practice for thirty years, encompassing the administration of chemotherapy to cancer patients, including head and neck cancer patients. N.T., voir dire, 5/1/06, at 61-62. During the same period of time, Dr. Blum served on, and sometimes chaired, tumor boards, in which capacity he was part of the multidisciplinary panel that reviewed and discussed individual patients to reach consensus decisions as to which treatment or combination of treatments should be recommended.11 Id. at [395]*39567. In addition, for over thirty years, he had conducted clinical studies designed to test new drugs and new treatments, particularly with regard to how to combine surgery, radiation, and chemotherapy treatments to achieve the best outcome. Id. at 64-65. He chaired a committee that made recommendations to the federal government concerning the funding of major cancer centers, and served on a number of external scientific advisory boards for various cancer centers. Id. at 66. In fact, Dr. Blum testified that one of the external scientific advisory boards on which he has served was the board for Thomas Jefferson University Cancer Center. Id. He has been a professor of medicine at the Albert Einstein College of Medicine and the Director of the Cancer Center and Programs for the Beth Israel Cancer Center in New York City since 1999. Id. at 61, 63; Curriculum Vitae of Ronald H. Blum, M.D., at 2. Given all these unchallenged and unrefuted professional qualifications and activities, we readily conclude that Dr. Blum was competent to offer his opinion as to whether the standard of care applicable to Dr. Spiegel’s and Dr. Anne’s treatment of Mrs. Vicari included discussing with her the option of follow-up chemotherapy and referring her to a medical oncologist for this purpose.
In sum, we hold that, under subsection 512(e), Dr. Blum had sufficient training, experience, and knowledge to testify as to standard of care for the narrow, specific issue of care presented, due to his active involvement in a field of medicine related to that of the defendant physicians.
