Ovarian cancer is the eighth common cancer in women. This type of cancer is formed in the tissues of the ovary (which are one of a pair of female reproductive glands in which the ova, or eggs, are formed).

The early stages of ovarian cancer may not cause any obvious symptoms but these are the symptoms that have been report by indigestion, heartburn, nausea, gas, abdominal swelling or discomfort, pelvic pain or cramping, bloating or a feeling of fullness, even after a small meal, painful, frequent, or burning urination with no infection, diarrhea or constipation, loss of appetite, unexplained weight loss or gain, unusual fatigue, low back pain, shortness of breath, abnormal vaginal bleeding or irregular periods, and pain during intercourse.

Genes may play part in inheriting the trait for ovarian...
