I’m so confuse, I'm 50 year old, my doctor is stating that a possibility of ovarian cancer. My symptoms are, pelvic lower, frequent bloating & urine, lower back pains, including constipation. My stomach feels so bloated feels like if am three months pregnant. I have done the CA-125 tumor marker and came back normal. However, have to go for ultrasound tomorrow. I don’t know if I should be worried, since the tumor marker were normal?
