Opinion for the Court filed by Circuit Judge MIKVA.
Appellant, Amy Shields, challenges a district court decision granting summary judgment for appellee, Eli Lilly and Company (“Lilly”). Shields filed a tort claim against Lilly alleging that she contracted cancer as a result of having been exposed in útero to Lilly’s product, diеthylstilbes-trol (“DES”). The trial court granted Lilly’s motion for summary judgment on the ground that Shields had presented no conclusive proof that she had been exposed to DES. We have reviewed the district court’s determination de novo, and because we do not find it to be сonsistent with controlling precedent or the facts presented, we reverse.
BACKGROUND
Amy Shields filed suit in federal district court against Eli Lilly and Company, alleging that she developed clear-cell vaginal cancer as a result of being exposed tо DES while she was a fetus. DES is a medication that was manufactured by Lilly for pregnant women to reduce the risk of miscarriage. The FDA banned DES in the 1970s after overwhelming evidence linked its use to the development of clear-cell vaginal cancer in women whose mothers received the drug during pregnancy.
See Eli Lilly & Co. v. Home Insurance Co.,
Following discovery, Lilly filed a motion for summary judgment arguing that plaintiff could not prove that she had been exposed to DES. In response, appellant acknowledged that she did not have any direct evidence of exposure to DES. Her mother received medication during the course of her pregnancy but was never told its name. The doctor who prescribed this medication is deceased, and both his prescription rеcords and those of the pharmacy that dispensed the medication have been lost. Nevertheless, appellant proposed to identify the medication as DES, based upon her mother’s physical description of the medication, the circumstances under which it was prescribed, and the professional practice of the doctor who prescribed the medication.
In the summary judgment proceeding, appellant introduced medical records which showed that her mother, Mrs. Shields, experienced a type of bleeding (“staining”) while pregnant with appellant; this condi *1465 tion is typically associated with miscarriages. Mrs. Shields testified that when bed-rest did not stop the staining, her physician, Dr. Sinclair, prescribed mediсation for her. Although Mrs. Shields could not identify the drug by name, she recalled that it came in a small, red pill.
Dr. Sinclair’s nurse, Mrs. Clifford, testified that the doctor sometimes prescribed medication in pill form for patients who were staining or in danger of aborting, and that when he did so, his practice was to prescribe either DES or progesterone. Appellant presented the affidavit of Dr. Linwood Tice, an expert in pharmaceutical history, who stated that although DES came in the form of small red рills, no progesterone commonly and ordinarily on the market in the 1950s met this description.
Finally, appellant introduced the records of several doctors who had examined her. The first examination took place nine years before appellant was ever diagnosed as having cancer. The attending physician, Dr. Isvan Nyrjesy, detected some irregularities in her uterus and on this basis concluded that she had probably been exposed to DES. The following year, appellаnt was examined by another doctor, Dr. Donald Meek, who also concluded that she had probably been exposed to DES. In 1986, Shields was diagnosed as having “clear cell carcinoma of the vagina,” which her doctor observed was aсcompanied by “typical DES-associated changes.” Appellant’s tissue samples were submitted to Dr. John Shane, who stated in his affidavit that “such lesions do not occur in the absence of DES exposure ... and do not appear in the absеnce of DES exposure to a statistical certainty of 97% to 99.7%.”
After considering this evidence, the trial court concluded that appellant had not carried her burden of showing sufficient evidence to prove exposure at trial. Accordingly, it granted the summary judgment motion. Appellant challenges this conclusion on the grounds that the trial court imposed an unduly high standard of proof and that, applying the appropriate standard, her offer of proof was sufficient to withstand summary judgment.

Standard for Summary Judgment
A court may dispose of a case on summary judgment before trial only where there is no genuine issue as to any material fact. Fed.R.Civ.P. 56(c). The standard test for summary judgment is “whether a fair-minded jury could return a verdict for the [nonmovant] on the evidence presented.”
Anderson v. Liberty Lobby, Inc.,
In evaluating the nоnmoving parties’ showing, this court has directed the trial judge to consider the cumulative effect of the evidence,
Catrett v. JohnsManville Sales Corp.,
The “significantly probative” test does not require the nonmoving party to discredit every conceivable alternative theory of causation. As this court noted in
Elliott v. Michael James, Inc.,

II
The District Court’s Findings of Fact
The district cоurt found that appellant had not presented sufficient affirmative proof in her pretrial papers to carry her burden of establishing that she was exposed to DES, because none of the affidavits she offered — either separatеly or in combination — conclusively supported exposure.
The trial court identified as its “critical finding” that “there is no reasonable basis upon which to infer, as plaintiff avers, that the pill was none other than DES.”
The trial court has changed the burden of proof into a certainty of proof. It held that none of the evidеnce, even if fully credited, could disprove the possibility that appellant had not been exposed to DES and that her condition was the product of other forces. That is not the law.
As noted, the “significantly probative” test requires only that thе evidence — singly or collectively — be sufficient to support a reasonable inference that substantiates a party’s claim. It is, of course, possible that Dr. Sinclair departed from his normal practice and gave Mrs. Shields a placebo or a cold medicine; it could well be that Mrs. Shields’ Kansas City pharmacist produced small red progesterone tablets in his basement, unbeknownst to pharmaceutical historians. But these possibilities merely raise questions to be considered by the jury — not insurmountable barriers to getting a case to the jury. “Significantly probative” means only that, if accepted, the facts make it more likely than not that the element pressed by appellant is present. Whether or not the elemеnt is present in fact is for the jury to decide.
Applying this standard to the evidence presented on summary judgment, appellant amply carried her burden of showing evidence that would support her claim of exposure. Nurse Clifford’s and Dr. Tice’s testimоny are significantly probative of exposure. Like the trial judge, we are bound to accept as true Mrs. Shields’ claim that Dr. Sinclair prescribed a small red pill as treatment for her staining. Nurse Clifford’s testimony supports the conclusion that Dr. Sinclair administered either DES or progesterone to Mrs. Shields, since these were the only pills that he normally prescribed for women who were experiencing staining. Dr. Tice’s affidavit was introduced to rule out the possibility that the pill Mrs. Shields remembers was progestеrone. He stated that “there was no progesterone or progesterone-type medication commonly and ordinarily on the market and dispensed which was red in color and smaller than an aspirin in size.” Taking these statements togethеr, a reasonable juror could conclude that the only medication that fits the medical and physical descrip *1467 tion of the drug which Mrs. Shields took while pregnant with appellant was DES.
In a factually similar case,
Bulthuis v. Rexall Corp.,
Conclusion
In a world short of absolutes, the jury is called upon to process less than perfect evidence. Litigants may not offer speculations or slight possibilities in support of their claims; but neither are they limited to offering only the incontrovertible. The jury’s function contemplates that evidence may be less than indubitable. Appellant produced more than sufficient evidence for a reasonable juror to conclude that she had been еxposed to DES. Appellant offered evidence that her mother’s doctor prescribed DES to patients who experienced staining during pregnancy, that her mother received medication for such staining, that the medication matchеd the description of DES and no other likely drug, and that several doctors who examined Shields both before and after she contracted cancer expressed the belief that she had been exposed to DES. This evidence was significantly probative of exposure. Every conceivable alternative theory of causation need not be extirpated by a litigant seeking the jury’s decision.
The trial court’s grant of summary judgment is reversed; we remand the case for further proceedings in accordance with this opinion.
It is so Ordered.
