I'm doing pretty good on the keytruda. I've only had one dose so far, but am going for my second in 2 weeks. I only had stomach ache for 1 day. The tumor has definitely gotton bigger though on my arm...actually appears larger than the first one that was cut out. This second is only an ich away from the incision of the other taken out 1 year ago. The surgery team did a pep smear to see if they could see more than this one and a small satellite one only a centimeter from the larger one. I guess they wanted to schedule the surgery, but wanted to make sure it hadn't spread so I would be a candidate, The more I read about cancer and treatment, the more I realize no one knows what works and what doesn't. Every case is so different where some do all the stuff, chemo, radiation, target therapy, adjuvaunt, neoadjuvant, etc. I hope I made the right decision on keeping this tumor in while the keytruda has something to fight against, but in the back of my mind im thinking, "Cut this bastard out before it spreads"!
