[|Human|] Hi there. My Dad had prostate cancer . He is 79 Recent PSA levels have dramatically rised from 104 six months ago, 1064 one month ago and yesterday it shot up to 1600, thats a rise of 600 in 3 weeks! They have told him without Cemo it could be 3 to 6 months. Today he felt v tired and he is starting to feel pain in his lung areas, low down in his back. This is a big PSA jum isn t it? Realistically, is 6 months optimistic?
[|AI|]  First understand that no one can predict lifespan accurately and all that is uttered is from literature evidence. But each individual behaves differently and response to medication also differs. Since he is symptomatic he definitely requires treatment. Treatment improves his quality of life, and he can be symptom free. So instead of worrying over PSA, concentrate on patient symptoms and get him treated
