Ovarian cancer is the cancerous growth in ovaries. It is 5th leading cause of death in women due to cancer. It arises from outer lining of the ovary i.e by epithelium. The risk of cancer increases with age and decreases with pregnancy. It is usually common above the age of 50 yrs. It is mostly associated with the mutation in the BRAC 1 and BRAC2 genes. These genes are responsible for suppression of tumour i.e they are tumour suppressor gene and prevents the mutation of genes which can cause error in repair of damaged DNA. According to the structure present in the ovary, three types of ovarian cancer are known:
1. Ovarian epithelial carcinoma
2. Sex chord stromal carcinoma.
3.Germ cell tumour
Sometime it may happen that cancer arising from other parts of the body may get enter into the ovary due to migration by blood or lymph and gets embedded there. In this case the cancer in the ovary is secondary cancer not a primary one. Usually secondary cancer in ovary arises from the breast and gastrointestinal cancers.

Pelvic or abdominal pain
Pain in the back or legs
Diarrhea, gas, nausea, constipation, indigestion
Difficulty eating or feeling full quickly
