When I was in my late 30's, I had similar symptoms to you. At the age of 40 I had a hysterectomy and after the surgery I was told that my uterus was precancerous. I also had one ovary removed. The other ovary had been removed in my late 20's, as I had cysts, which had burst. I had a quick recovery and felt better than I had in years. From my experience I would go ahead with the surgery.
