Concerned About Stomach Cancer. Stomach Pain, Nausea And Vomiting. Had Surgeries To Removed Mesh And Repair Hernia

I had a edg and colonoscopy, colonic manantery study today. I was told they took 12 biopsies of my upper stomach, bile gastritris, hital hernia, normal duodenum and jejunum and polypodal lesion in the proximal stomach. I have been refered for a EUS. I am now worried that the lesion may be cancer. In october 2012 I had the following surgeries done on the same day, 3 layers of mesh removed, sides flank and pig skin put in, 2 ft of my bowel removed, hernia repaired, nesefundicfication done too. I have had nothing but trouble since my surgery. i am still on basically soft foods with constant pain, nausea and vomiting. What can you advise me
