I have stage 4 endo and have a 7-8cm complex cyst on my ovary. As I developed the cyst while on lupron, this puts me at risk for the cyst to be cancerous. Dr, has told me that my endo is so severe, that I have a 50%chance of having to have a gastric bag after surgery (complete hyst.) and doesn't even want to attempt to do a biopsy yet for the same reason. My cyst grew over 1 cm in 1 week. They are waiting 6 weeks to re-ultrasound to see if it has grown more - then will make a plan. I am soooo worried. My grandfather just died of cancer, my father has 5th stage cancer, its all just too much. I feel so helpless. So many tell me that they had a hysto and felt better and why haven't I had one yet - but they are telling me that my case is just toooooo severe. Anyone out there in my boat???
