OPINION
Margaret MacRae brought this malpractice action after her husband, Roderick MacRae, died from cancer. The district court dismissed the complaint, finding that
The relevant facts in this case are not disputed. On January 15, 2001, Roderick MacRae had a routine physical examination with respondent Dr. Michael Kelly, his primary care physician. During this examination, Dr. Kelly performed a shave biopsy on a lesion on Roderick’s left leg and sent the tissue to the pathology department for analysis. Respondent Dr. Amar Subranaanian analyzed the tissue sample and reported on January 18 that it was a non-cancerous compound nevus. 1
More than 18 months after the biopsy, on July 31, 2002, Roderick saw Dr. Kelly due to a bulge in Roderick’s right groin. Dr. Kelly diagnosed the bulge as a hernia and referred Roderick to Dr. Steven Mes-titz for a surgical consultation. Roderick eventually decided to have the hernia surgically repaired. In preparation for this surgery, Dr. Kelly performed a pre-opera-tive examination of Roderick on December 9, 2002. According to the expert affidavit submitted by Margaret in this case, “[t]he standard of care requires palpitation of both inguinal [groin] lymph nodes as part of the preoperative physical.” Roderick’s medical records do not indicate that any abnormalities in these lymph nodes were discovered during the December 2002 examination.
On September 15, 2004 — approximately 21 months after his hernia surgery and 44 months after the initial biopsy — Roderick saw Dr. Kelly for swelling in Roderick’s left leg and groin. A CT scan performed that day indicated that the lymph nodes in Roderick’s left groin and pelvic areas were enlarged. Dr. Kelly again referred Roderick to Dr. Mestitz. After two surgical biopsy procedures, Roderick was diagnosed with metastatic malignant melanoma. 2 As a result of this diagnosis, the tissue from the 2001 biopsy of the lesion on Roderick’s left leg was re-examined and found to be a malignant melanoma, not a compound nevus as originally diagnosed. An amended pathology report was filed on November 2, 2004, and Roderick was informed of the misdiagnosis the next day.
Roderick died on August 26, 2005. The autopsy report concluded that the cause of death was “extensive metastatic malignant melanoma” that had spread to Roderick’s brain, neck, liver, pancreas, small intestine, adrenal gland, and abdominal wall.
On February 20, 2006, Margaret, as trustee for the next of kin of Roderick,
The defendants moved for summary judgment, arguing that the 2001 misdiagnosis was a discrete act of negligence and that the medical malpractice suit is therefore barred by the 4-year statute of limitations. In support of their motion, the defendants submitted Roderick’s medical records but did not offer any expert evidence regarding the growth or spread of his melanoma between the 2001 misdiagnosis and the eventual correct diagnosis in 2004.
Margaret responded that her claim is not barred because “the cause of action did not accrue until [Roderick’s] cancer reached the point where he could not survive.” In an affidavit submitted to the district court, a medical expert retained by Margaret indicated that melanoma that originates in the left leg will first become metastatic in the inguinal lymph node. Because no abnormality was noted in these lymph nodes during Roderick’s December 2002 pre-operative examination, the expert concluded that Roderick’s cancer likely had not yet metastasized and he likely would have survived if his cancer had been discovered and treated at that time. In the alternative, Margaret argued that her claim was not barred because the misdiagnosis was part of a course of treatment of Roderick’s leg and skin condition that did not terminate more than 4 years before Margaret commenced the action.
The district court ordered summary judgment for the defendants. The court noted that “[t]here is a ‘longstanding principle that malpractice actions based on failures to diagnose generally accrue at the time of the misdiagnosis, because some damage generally occurs at that time.’ ” (Quoting
Molloy v. Meier,
Margaret appealed, arguing that her cause of action did not accrue until after December 2002. Margaret argued that she did not suffer legally compensable damage until it became more likely than not that Roderick would not survive his disease, and that this happened within the 4-year limitations period.

No. A06-1982,

This case comes to us on review of the entry of summary judgment. Summary judgment is appropriate where “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that either party is entitled to a judgment as a matter of law.” Minn. R. Civ. P. 56.03. When reviewing dismissal of a claim on summary judgment, we examine the record to determine (1) “whether there are any genuine issues of material fact,” and (2) “whether the district court erred in its application of the law.”
Antone v. Mirviss,
A.
The parties agree that the factual record is undisputed, so the only issue before us is whether those undisputed facts establish that Margaret’s claim is barred by the applicable statute of limitations. The construction and application of a statute of limitations, including the law governing the accrual of a cause of action, is a question of law and is reviewed de novo.
Antone,
The statutory limitations period that governs Margaret’s medical malpractice action is set forth in Minn.Stat. § 541.076(b) (2006): “An action by a patient or former patient against a health care provider alleging malpractice, error, mistake, or failure to cure, whether based on a contract or tort, must be commenced within four years from the date the cause of action accrued.” See also Minn.Stat. § 573.02, subd. 1 (2006) (allowing a trustee to maintain a wrongful death action for medical malpractice on behalf of the next of kin if the action is commenced within 3 years of the death and satisfies the timing requirement in section 541.076). 5 Although the limitations period begins to run when the cause of action accrues, the statute does not define when such accrual occurs.

On appeal, Fabio argued that she should have been allowed to amend her complaint to include Dr. Bellomo’s failure to order further testing on the lump during the 1982-84 examination because that conduct was part of a continuing course of treatment.

Fabio,
II.
Because we have not previously decided whether some damage occurs as a matter of law at the time of a cancer misdiagnosis, we now turn to whether we should adopt such a rule in this case. Courts use different approaches to determine when injury or damage occurs for purposes of accrual of a cause of action. For example, the “occurrence” approach “assumes that nominal damages occur, the cause of action accrues, and the statute of limitations begins to run, simultaneously with the performance of the negligent or wrongful act.”
Antone,
Both of these approaches, however, are inconsistent with our long-standing precedent. We have repeatedly held that a negligent act is not itself sufficient for a negligence cause of action to accrue.
Dalton,
Accordingly, we have rejected both the occurrence and discovery approaches in favor of a “middle ground”— the “damage” rule of accrual.
Antone,
Thus, consistent with our precedent, in order to justify a rule that a cause of action accrues as a matter of law at the time of a cancer misdiagnosis, we would have to conclude that some legally com-pensable damage necessarily occurs at the time of such a misdiagnosis. We decline to adopt such a broad rule of law. Rather, consistent with our precedent and the precedents in other states that apply a “damage” rule for the accrual of a cause of action, we believe that the limitations inquiry in cancer misdiagnosis cases should be conducted based on the unique record developed in each particular case.
This case-by-case approach is consistent with our precedent suggesting that the continued presence of cancer following a negligent misdiagnosis, by itself, may not be compensable damage.
See Leubner v. Sterner,
Additionally, courts in other jurisdictions that apply a “damage” rule of accrual have held, as we suggested in
Leubner,
that the continued presence of cancer is not itself sufficient for a cause of action to accrue and the statutory limitations period to begin running. In
St. George v. Pariser,
[The plaintiff’s] actionable injury was not the generic disease of cancer or the cancer “in situ” which she had when she sought evaluation of the mole in 1991. [The doctor’s] negligence could not have been the cause of that medical condition. [The plaintiffs] injury was the change in her cancerous condition which occurred when the melanoma altered its status as “melanoma in situ,” a biologically benign condition, to “invasive superficial spreading malignant melanoma” in the dermis which allowed the melanoma cells to metastasize to other parts of the body.
Id. at 891. Because the record did not establish that the injury had occurred outside of the limitations period, the court held the doctor had “wholly failed to meet his burden of proof to sustain his statute of limitations plea.” Id.
Similarly, in
DeBoer v. Brown,
Where a medical malpractice claim is based on a misdiagnosis or a failure to diagnose a condition, the “injury” is not the mere undetected existence of the medical problem at the time the physician misdiagnosed or failed to diagnose it. Nor is the “injury” the mere continuance of the same problem in substantially the same state or the leaving of the patient “at risk” of developing a more serious condition. Rather, the “injury” is the development of the problem into a more serious condition which poses greater danger to the patient or which requires more extensive treatment.
Id. at 914. Applying this rule to the facts before it, the court held that the injury occurred, and the statute of limitations began to run, in 1979, when the lesion began to grow. Id. at 913-15.
We agree with the reasoning of the Virginia and Arizona courts and conclude that the continued presence of cancer — by itself — is not evidence of compen-sable damage in a malpractice action for negligent misdiagnosis. As we indicated in
Molloy,
we have long recognized that “some damage” usually occurs at the time of a misdiagnosis.
III.
Having declined to adopt a blanket rule that “some damage” occurs as a matter of law at the time of a cancer misdiagnosis, we must determine whether the respondents in this case established that Roderick suffered some compensable damage more than 4 years before Margaret commenced her medical malpractice action. Margaret argues that no compensable damage can occur in a cancer misdiagnosis case until it is more likely than not that the patient will not survive the disease. Based on the affidavit testimony of her medical expert that the results of Roderick’s preoperative examination in December 2002 indicate that he likely would have survived his melanoma if it had been properly treated at that time, Margaret argues that her claim is timely under such a rule.
Margaret supports her argument with cases in which we have rejected several theories of damage or potential damage that may result from a misdiagnosis of cancer. Margaret cites
Leubner,
where, while considering whether the patient had established that any damages were caused by the negligent act, we declined to recognize “negligent aggravation of a preexisting condition” as a legally compensable injury.
We agree that a patient suffers compensable damage from a negligent misdiagnosis of cancer when it becomes more likely than not that he will not survive the disease. But we do not agree that this is the only possible compensable damage in such eases. As we have previously recognized, the accrual of a cause of action for professional malpractice is not limited to the damage or cause of action “specifically identified in the complaint.”
Antone,
We therefore decline Margaret’s invitation to hold that no compensable damage can occur in a cancer misdiagnosis case
In this case, the district court made a legal conclusion that the cause of action accrued and the statute of limitations began to run at the time of the misdiagnosis. Based on this conclusion, the court did not make any findings regarding whether there is an issue of material fact as to when Roderick suffered a legally compensable injury caused by the misdiagnosis of his cancer. Based on our own review of the record, we conclude that respondents did not establish that Roderick suffered some damage more than 4 years before February 20, 2006, when Margaret commenced this action. Respondents did not offer any expert evidence regarding the growth or spread of Roderick’s melanoma between the 2001 misdiagnosis and the eventual correct diagnosis in 2004. They instead supported their motion with copies of Roderick’s medical records. But those records do not establish that Roderick suffered damage from the misdiagnosis before February 20, 2002 (4 years before this action was commenced).
Respondents also point to the affidavit of the expert Margaret retained to support their argument that Roderick incurred some damage after the January 18, 2001, misdiagnosis. Specifically, respondents point to this expert’s acknowl-edgement that Roderick’s disease had a “natural progression” from the time of the misdiagnosis. But the question is whether the natural progression of the cancer had consequences that constitute compen-sable damages before February 20, 2002, and the record is barren on that issue.
In sum, based on our review of the record we hold that respondents have not met their burden of establishing that Roderick suffered compensable damages from the misdiagnosis prior to February 20, 2002. We therefore reverse the decision of the court of appeals and remand to the district court for further proceedings consistent with this opinion.
Reversed and remanded.

. A nevus is "[a] birth mark or a small growth on the skin, appearing before or shortly after birth, consisting of either blood vessels or skin and connective (supporting) tissue. A nevus is usually pigmented. Same as a mole.” 3 J.E. Schmidt, Attorneys’ Dictionary of Medicine and Word Finder N-95 (1995).
. According to the American Academy of Dermatology:
Melanoma is a cancer of the pigment producing cells in the skin, known as mela-nocytes. * * * Normal melanocytes reside in the outer layer of the skin and produce a brown pigment called melanin, which is responsible for skin color. Melanoma occurs when melanocytes become cancerous, grow, and invade other tissues.
Melanoma begins on the surface of the skin where it is easy to see and treat. If given time to grow, melanoma can grow down into the skin, ultimately reaching the blood and lymphatic vessels, and [sjpread around the body (metastasize), causing life-threatening illness. It is curable when detected early, but can be fatal if allowed to progress and spread.

. The district court stated that "[o]n January 17, 2001, Dr. Subramanian’s pathology report stated that * * * the left leg specimen was a compound nevus” and that the misdiagnosis of Roderick's lesion "occurred on or about January 17, 2001.” But it appears that the tissue sample from Roderick's biopsy was received by the pathology department on January 17 and that the report and diagnosis were made on January 18.
. Margaret appears to have abandoned her argument that there was a continuing course of treatment.

. The present wrongful death action was commenced on February 20, 2006, less than 6 months after Roderick’s death. Thus, the only question in this case is whether the action satisfies the timing requirement in -Minn. Stat. § 541.076.

would have construed the 1982-84 examination as part of a continuing course of treatment with the 1986 examination.
. Skin is comprised of two parts: an outer layer called the epidermis, and a deeper layer called the dermis. See 4 Schmidt, supra, at S-l24-25.
. Amicus curiae Minnesota Association for Justice suggests that our rules governing the accrual of a cause of action ''require!] that plaintiff have a meaningful opportunity to have
knowledge of the facts upon which the claim is based
and that accrual cannot occur until

the elements of the cause of action can be established.” (First emphasis added.) This language implies a "discovery” rule of accrual, which we have consistently declined to adopt.
