[|Human|] My sister had a very large tumor from anal cancer last winter. She got treatment at AAAAAAA Kettering, and they were able to get rid of it through aggressive radiation and some chemo . But there was bad news a month ago, after her last follow up CAT scan - the cancer has spread into her liver and some lymph nodes near her stomach. The doctors gave her no hope, and said all they could do would be give her chemo to try and help prolong her life. She s leaning towards not taking the chemo, because she wants to enjoy what time she has without the downsides of chemo. My question: how much longer can we expect her to live?
[|AI|]  Hello friend.I'm really sorry to hear about your sisters' ailment.since the cancer has spread extensively, especially liver, the prognosis is very bad. Exact life expectancy cannot be pointed. It may vary from 1,2 or 6 months. It depends on how much of it has spread to the liver. However in rare cases the patients can be operated to remove the tumors if there are limited number of tumors in the liver. But in the majority of cases, metastasis to the liver is not curable! Just make sure that she is given a good palliative care and do spend a lot of time with her as she needs a lot of psychological support at this time.take care.
