Endometriosis

I have had cancer before, I am 32 we pretty much summarized the other question I posed with very intelligent articulated answers, I don't want speculation and stories of adversity I understand the need to share but really I am looking for honest truth, everyone is an individual case and all diagnosis is different but being that caner runs significantly in my family, I have accepted that I may face the same obstacle what can I do NOW, to limit the probability or slow the progression of the disease, diet, routine, checkups, options etc... I don't want to overwhelm myself but really I am scared a little.

I also have epilepsy and fibromyalgia pretty bad, luckily I still have a good Body and looks but underneath it all I feel bad, emotionally, spiritually, physically! LOL! I have my son, my only son you can imagine what goes through my mind, so what exists medically, what steps should I take
