[|Human|] My Father has decided to stop chemo for liver cancer because he feels sick all the time. The cancer in the liver spread from colon cancer. They told him 3-6 months without chemo, 6-1yr with chemo. The tumors have shrunk to about half their original size. He has been on chemo for 6 months. My question is, will the cancer spread quickly when he stops chemo? Any idea what kind of time frame we may be dealing with now?
[|AI|]  Welcome to ChatDoctorThanks for the query. It is always hard to predict the dynamics of tumor spreading, especially metastatic, but it will cause by statistics faster spreading and less life expectancy. However, many people quit behemoth since generally this life prolongation with behemoth is usually just few or several months and chemo effects may be unbearable. So it is his decision and whatever he decides it won't be wrong. If he survived 6 months then it may indicate that he has good immune system, but as you already know prognosis is not good. Wish you good health. Regards.
