Would I know if my partner is being treated with radiotherapy and chemotherapy for cancer in his testicle? We have an active sex life and I am now surprised he's told me this news. I feel ashamed of my self for not believing him but I'm sure there would be many side effects and he wouldn't have been able to hide this from me? I would feel guilty to say I doubt him if it was true. He said he hadn't told me before in fear of rejection. Please advise me what symptoms to expect which might help to put my mind at rest . He has been under the weather and off work, with depression and psoriasis, so he had previously told me, so are these really the symptoms for the side effects of his treatment which is now what he is saying?
