I was diagnosed with stage 4 anal cancer January 2021. There was one large tumor and ten small ones. The large tumor caused a bowel blockage so I had an emergency colostomy. Then I had 10 days of radiation where I lost 22 pounds, had no appetite and was exhausted. This was followed by a year of chemotherapy and two years of immunotherapy with Keytruda. The colostomy was reversed early 2023. There was no sign of cancer, so in November 2023 they stopped treatment. The Pet scan this past December found a new tumor. I had surgery to have it removed in March. So I am back on Keytruda, probably for the rest of my life. Hoping for the best and staying positive.
