Possible cancer link to ovulation induction

February 25, 2009 The study found treatment with ovulation-inducing drugs was not associated with ovarian cancer but increased the risk of breast cancer by 42 percent, uterine cancer by more than 3 times and the risk of non-Hodgkins lymphoma by almost the same amount.

Treatment with clomiphene specifically was associated with almost 5 times the risk of uterine cancer and close to 3 times the risk of malignant melanoma.

Scientists say this study should result in better registries of fertility treatments to keep an eye on patient health.
