Ovaries are the small, ovoid structures on either side of the uterus. Whenever we talk about cancers in women, we must be aware of masses or tumours – benign and malignant, of the ovaries. Although cancers of the ovary are the fifth most common cancer in women after breast, colorectal, lung and uterus; they are the most common cause of death in women due to cancer. Women with ovarian cancer have the least 5 year survival rate as compared to all other cancers. This is because cancer of the ovaries is a ‘silent killer’ – 70% of ovarian cancer is diagnosed in advanced stages, which means that the disease is already widely spread in the abdomen by the time it is diagnosed.
