<s>[INST] my father in law has iv stage prostate cancer he is sleeping a lot ,suffering from lower back pain,geeting white colour stool which he cant controls,not feeling like eating,some time feels like vomiting after eating,his age is62 can u please tell me how long is he in this earth [/INST] Thanks for your question on Chat Doctor. I can understand your father-in-law s condition. By his symptoms of urine and stool incontinence, in my opinion he is having bone metastases to lower vertebrae. This causes cord compression and loss of bowel and bladder control. Prostate cancer is known to cause bone metastases to vertebrae. So he is mostly having stage 4 (end stage) prostate cancer. Life expectancy in such cases is less than 6-8 months. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father-in-law. Thanks. </s>
