How would you feel in my situation

Me and my husband are going through a lot. He was diagnosed with prostate cancer. He was planning on starting chemo but he didn't like his doctor because he was extremely rude, unsympathetic, and was pretty much just trying to convince him to remove his prostate even though he's early enough where chemo could work. Removing his prostate would make him infertile and he also really likes prostate orgasms. Sorry if that's TMI. But my husband and is trying to switch doctor's. The only other one in our town is a lady. Her office has really good reviews. I don't know how comfortable I feel about that. My husband broke my trust in the past. He didn't exactly cheat but he lied to me. We've been together since high school. When we were 16 he had this female friend that I didn't like. He hung out with her alone and lied to me about it and he said he lied because he knew I would be upset if he told the truth. That really hurt me. It was a long time ago but it does still hurt. I told him we can just keep his doctor and demand we try chemo first but he said he doesn't like the guy. How would you feel... Knowing another woman will be in an intimate situation with your husband and he's broken trust in the past?
