[|AI|]  Thanks for your question on Chat Doctor. I can understand your fathers situation and problem. Since his PSA values are rising even with treatment, his prognosis is poor. And possibility of metastatic prostate cancer is high. Dizziness and weakness can be due to brain metastasis. Rhythm disturbance in heart can be due to metastatic lesions in heart. So better to consult oncologist and get done PET scan to rule out distal metastasis. Honestly speaking, chances of survival are very, very less. If metastases are there than life expectancy is less than 1 year. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
