Prof Curt Burger talks to ecancer at the 2012 International Gynaecologic Cancer Society meeting in Vancouver about the relationship between ovarian cancer and endometriosis sub-fertility.

From a study that began in 1993, data collected from two groups of women confirmed that both endometriosis and fertility drugs significantly increased the risk of ovarian cancer.

Now analysis of a patient's histology and study of border line tumours allows for greater evaluation of risks and progression of the disease.
