Cancer Survivors Network

I have been having pelvic and abdominal pain for about two years. Last year, I had a uterine biopsy that showed reactive endometrial cells which prompted a d & c, laprascopy, and hysterocopy. This procedure showed cysts, chocolate cysts, polyps, small tumor, etc. Doctor then told me that it looks like I have Primary Peritoneal Carcinoma. She sent me to a teaching hospital, which said as long as no atypia is present, they don't believe treatment is necessary.
Since that time, I have been diagnosed with gastritis, three hernias, esophageal inflammation, inflammation in the lungs, colon, appendix. Now, I also have adenomyosis and fluid in the abdomen. At my last ultrasound, they found a possible fibroid tumor on my right ovary and left ovary is attached to the wall.
My latest discovery is that a family member died at the age of 48 with a rare stomach cancer that was very similar to what I am going through. No one could/would diagnos until it was too late to treat and he died within the year.
I am 29 and am overwhelmed and not sure what to do or what the next steps I should take. Has anyone has a similar experience? Any thoughts?
