These consolidated appeals arise out of plaintiffs medical malpractice action alleging that the death of the decedent, Geoffrey Shawl, resulted from the misdiagnosis of his cancer in 1983 and 1986. In Docket No. 144823, plaintiff appeals as of right from an order of the circuit court granting for defendant Pradeep P. Dhital, M.D., summary disposition pursuant to MCR 2.116(C)(7). In Docket No. 145041, plaintiff appeals as of right from an order of the circuit court granting summary disposition for defendant Doug Pratt, M.D., doing business as BPS/Tri-County Medical Laboratory. In Docket No. 148128, plaintiff appeals as of right from an order of the circuit court granting summary disposition for defendants Robert H. Chatfield, D.O., individually, and doing business as Beecher Pathologists, P.C. Finally, in Docket No. 146016, defendant Robert K. Hafford, M.D., appeals by leave granted from an order of the circuit court denying his motion for summary disposition. We affirm in part, reverse in part, and remand the action to the trial court.
In reviewing a motion for summary disposition pursuant to MCR 2.116(C)(7), we must accept plaintiff’s well-pleaded allegations as true, Simmons v Apex Drug Stores, Inc, 201 Mich App 250, 252; 506 NW2d 562 (1993); Bonner v Chicago Title *324Ins Co, 194 Mich App 462, 469; 487 NW2d 807 (1992) , and consider all the documentary evidence submitted by the parties, MCR 2.116(G)(5). The motion should not be granted, however, if there are disputed factual issues concerning when discovery of the claim occurred, or reasonably should have occurred. Simmons, supra at 254; Griffith v Brant, 177 Mich App 583, 587; 442 NW2d 652 (1989).
The applicable statutory period of limitation for medical malpractice claims is two years after the "act or omission that is the basis for the claim of medical malpractice, regardless of the time the plaintiff discovers or otherwise has knowledge of the claim.” MCL 600.5805(4); MSA 27A.5805(4) and MCL 600.5838a(l); MSA 27A.5838(1)(1). However, in those cases in which an injury is not immediately apparent, MCL 600.5838a(2); MSA 27A.5838(1)(2) allows a plaintiff to commence an action within the two-year statutory period of limitation or "within 6 months after the plaintiff discovers or should have discovered the existence of the claim, whichever is later.” Here, plaintiff asserts that the trial court erred in ruling that his January 3, 1990, complaint against defendants Dhital, Pratt, BPS/Tri-County, Chatfield, and Beecher was untimely. Because these claims arose out of Dr. Dhital’s alleged misdiagnosis of the decedent’s biopsy sample in June 1986, plaintiff contends that a factual dispute exists concerning when the decedent discovered the claims.
In addressing plaintiff’s argument, we note that our Supreme Court recently clarified the appropriate standard for the discovery rule in Moll v Abbott Laboratories, 444 Mich 1; 506 NW2d 816 (1993) . See also Gebhardt v O’Rourke, 444 Mich 535, 544; 510 NW2d 900 (1994). In Moll, the Court adopted the "possible cause of action” standard. *325Under this test, a plaintiff is deemed to be aware of a possible cause of action when he becomes aware of an injury and its possible cause. Id. at 24. Further, the Court also concluded that in the absence of disputed facts, the question whether a claim is barred by the statute of limitations can be determined by the trial court. Id. at 26.
After applying the above principles, we are convinced that plaintiff’s claims were not filed timely for purposes of MCL 600.5838a(2); MSA 27A.5838(1)(2). The uncontroverted deposition testimony of the decedent’s father, plaintiff Roy Shawl, reveals that in June 1988, he and his son discussed his son’s medical condition. Plaintiff learned from his son that his son’s cancer had spread since he first sought medical treatment in 1983, and that his 1983 and 1986 biopsies allegedly had been misdiagnosed. In light of this testimony, it is clear that the decedent knew or should have known that a possible cause of the spread of his cancer was the alleged misdiagnosis by Dr. Dhital in 1986. Accordingly, under the discovery rule, the lawsuit had to have been filed before January 1989. Because the lawsuit was filed on January 3, 1990, plaintiff’s claims are barred by the statute of limitations.
We also reject plaintiff’s claim that his lawsuit was filed timely under the wrongful death tolling provision. MCL 600.5852; MSA 27A.5852 extends the time in which to file suit in a case in which a person has died before the period of limitation has run or within thirty days after the period has run. See, e.g., Hawkins v Regional Medical Laboratories, PC, 415 Mich 420, 438; 329 NW2d 729 (1982); Ortiz v Ferris, 128 Mich App 776, 778; 341 NW2d 215 (1983). Here, the period of limitation expired, at the latest, in December 1988. Plaintiff’s decedent died on August 2, 1989. Because the death of *326plaintiffs decedent occurred more than thirty days after the statutory period ended, MCL 600.5852; MSA 27A.5852 did not extend the time to file the decedent’s claims. The trial court did not err in granting summary disposition.
Turning now to defendant Halford’s consolidated appeal, we conclude that the trial court erred in denying his motion for summary disposition pursuant to MCR 2.116(C)(7). On appeal, Dr. Hafford asserts that plaintiffs malpractice claims alleging that he failed to perform properly the biopsies and provide necessary information for their accurate diagnosis were barred by the statute of limitations. Specifically, Dr. Hafford claims that the decedent knew or should have known of his claims against Dr. Hafford in June 1988, at the latest, when it is undisputed that he was aware that both of his biopsies were misdiagnosed. Therefore, Dr. Hafford contends that plaintiffs amended complaint filed on October 1, 1990, was untimely.
In contrast, plaintiff argues that the earliest Dr. Halford’s negligence could have been discovered was during the doctor’s deposition on May 31, 1990, and during the depositions of Dr. Dhital and Dr. Metwalli taken later that year. Dr. Dhital testified that Dr. Hafford did not provide crucial information necessary to the proper diagnosis of the biopsy sample, including the site from which the specimen was taken, the patient’s age, or that Dr. Hafford himself suspected cancer. Further, Dr. Metwalli testified that Dr. Hafford failed to perform properly the biopsies and withheld crucial information necessary to an accurate diagnosis. In essence, plaintiff claims that because of the complex nature of these claims, the decedent could not have discovered these claims until after the depositions.
However, plaintiff’s argument misapprehends *327the "possible cause of action” standard for the discovery rule in Moll, supra. Under this test, a claimant is deemed aware of a cause of action when the claimant has knowledge of an injury and its "possible” cause, thus encouraging claimants to investigate diligently and pursue causes of action in harmony with the policies underlying the statute of limitations. Consistent with this rationale, a claimant need not be aware of " 'the details of the evidence by which to establish his cause of action.’ ” Id. at 24, quoting Kroll v Vanden Berg, 336 Mich 306, 311; 57 NW2d 897 (1953).
Here, it is undisputed that plaintiffs decedent knew, at the latest, in June 1988 that his 1983 and 1986 biopsies had been misdiagnosed. Further, it is also undisputed that plaintiffs decedent knew that both of the biopsies were performed by Dr. Hafford and that he was responsible for sending the samples to be reviewed by the outside laboratories. Accordingly, given Dr. Hafford’s intimate involvement with the misdiagnosed samples, the decedent knew or with reasonable diligence should have known of his "possible” claims against Dr. Hafford, at the latest, in June 1988. Thus, plaintiffs failure to file suit by January 1989 bars his claims against Dr. Hafford.
In light of our disposition of Dr. Hafford’s appeal, we need not address his remaining issue on appeal.
Affirmed in part, reversed in part, and remanded for further proceedings consistent with this opinion. We do not retain jurisdiction.
