I had stage 4 endometriosis. iam 34 years old, 2 months before i have undergone surgery. my doctor removed uterus bag, two ovaries, as it is very complicated and critical condition. doctor informed that a bit of cyst is left as it is attched to colon, unable to remove or scratch as it will damage the colon. And it is a open surgery. can it gro again in colon and cause any problem in future. Is there any medicine to heal the cyst part from the colon.
