My step dad has terminal prostate cancer, he was diagnosed in 2014 and the cancer has spread to his bones. He's just had a 3rd dose of radiotherapy and he's on his 2nd round of chemotherapy for pain management. He is a stubborn man who refuses to let me help and he won't discuss his treatment, pain or anything cancer related because he doesn't want to upset me because I lost my mother to oesapagael cancer and I feel he's pushing me away so I don't see him suffer the same way as my mother. How can I help him without being pushy?
