What a terrible thing to suffer from, and a poor survival rate. Let’s hope that research will improve this survival rate.
My mother had ovarian cancer, and had no symptoms until one day she was in agony and went to her doctor. She was sent for a scan and then quickly into surgery, they discovered her cancer was at stage four. Surgery was a waste of time, they just closed her up as there was nothing they could do. She only had six months to live from the day she saw the doctor.
It is vital that people do have proper health check ups on a regular basis, some diseases are very difficult to detect though. But if you feel something is wrong go straight to your doctor. It is best to have a negative test result than a positive test result.
