Hi, Thanks for writing in. As you have consulted doctors in a specialist hospital, the doctors have evaluated your mothers condition in detail. Stage 4 cancer is when the growth is large and the cancer has spread to other organs like liver and lungs. Operating in such a situation will not help to control disease and might further reduce life of patient. Right now your mother first requires chemotherapy and radiation if recommended. Then she should get medications for her pain. It is possible that she will not be able to tolerate any thing given by mouth. If possible a stent like device might be placed in the cancer area but it is difficult to say if it will work unless complete details on exact location of cancer are available. If stent cannot be put then she has to take ryles tube feeding or total liquid diet. Radiation treatment might help and you can discuss this with your doctors. The average life expectancy in stage 4 cancer of gastric junction cancer is about 6 months to 18 months and depends on general condition of patient and response to treatment. Please do not worry.
