Yes I had an idea that endo increased the risk of cancer of the ovaries, bowel, uterus etc. My grandmother died of cancer of the uterus, and she had a huge age gap between children, so I have wondered if she had endo. I had my endo removed when I went to have my infertility investigated. We tried naturally after that, but it didn't work. IVF did though, so we are really lucky. Good luck!
