Abdominal bloating, pressure are one of the possible symptoms of ovarian cancer. They are commonly associated with other conditions, such as gas, menstrual cycle, or even weight gain, but if they do not go away on their own after a few days, you should consult a doctor.
Pelvic discomfort or pain, including pain during or after sexual intercourse, can be a sign of ovarian cancer. If the pain persists or even gets worse, you should have it checked. A constant, nagging pain in your lower back can also be a sign of something wrong in your pelvic area.
