[|Human|] My mother had colon cancer and recovered from that. When a pet scan was done it showed she had a spot on her liver it was stage 4, radiation was done, another pet scan was done and showed the radiation had worked, now the liver cancer has returned in the same spot and it is stage 5. The Dr said she can not do another round of radiation and chemo will not work. How long can she expect to live her life?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your mothers situation and problem. Colon cancer is very notorious in spread. Liver is common site for metastasis. And chemotherapy with radiotherapy are the treatment of choice for this. Since she is having recurrent liver metastasis besides treatment, better not to give her further chemotherapy and radiotherapy. Because chemotherapy and radiotherapy, both are very toxic to the patient and having a lot of side effects like weakness, lethargy, opportunistic infections etc. So better not to give her further treatment. Life expectancy in her case is less than 1 year. Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
