After two sessions of pembrolizumab my liver has been in trouble. A scan showed nothing wrong but the blood test wasn't right. After more tests I was told I have hepatitis caused by the treatment and tomorrow I start on a course of steroids - 14 a day for starters, and have to wait now before my treatment can continue. I'm also at risk of developing diabetes as well as putting on weight (after struggling to lose three stone!!). On the upside I look and feel well, so I suppose that's something. Keeping positive.
