Ovarian cysts can be just that, ovarian cysts, or they can be ovarian cancer. My mom who is only 60 went to the doctor for bloating and constant pelvic pain & just an overall feeling of "bad" and she was pretty much blown off as having a cyst that would rectify itself as cysts usually do. She was also unhappy and moody, not her usual self. Four months later the bloating was much worse and you could actually feel something, so she decided to see another doctor. This doctor said she now had a tumor she thought (not a cyst - different sound waves are made by tumors than cysts) that was about 6 inches (after some tests and an ultrasound). They were not sure whether it was cancer until she had surgery. Even though a blood test indicated it was since her CAT score was 400 (normal is 35 & under). It was Ovarian Cancer and that 6 inch tumor was actually her ovary that became wrapped in the tumor.
Get a second opinion if you are in constant pain and feel like the doctor is not taking your concerns seriously!
My mom has now had surgery and the tumor ruptured during surgery. It is clear cell cancer, so they don't really know if they got it all. She is undergoing 6 rounds of chemo 3 weeks apart and after this 4th round finds herself completely exhausted and in excruciating pain 24/7 - even with pain medications to help manage it. She is in so much pain and so exhausted that she didn't even "do" Christmas (which is not my mom at all).
Earlier & accurate diagnosis is always better. Make sure you feel your doctor is truly listening to you and exploring all avenues to ensure you are receiving accurate information and a quality relief/ease of symptoms. Remember these doctors work for you. Wishing you the best!
