Women, request a CA-125 test.
I had all of the symptoms listed here for over a year. I saw 10 different doc.s! One for the back aches, three OBGYNs for the "ovarian pain", and another for terrrible headaches. I had one OBGYN say, "some girls hurt more than others.." I was blown off a lot. Turns out, I had ovarian cancer that was overlooked. I had "normal" paps. and ultrasounds, and pelvic exams 4 days prior to getting my blood test results.
