<s>[INST] Hello, I was wondering if this statement was true. My mother is dying of stage 4 stomach cancer, and frequently suffers from uncontrollable pain. Upon taking her to the Emergency Room I was told by a ER doctor that since she has advancing cancer, there is not a whole lot they can do and she has one of two choices. One, they can admit her as a patient under observation and give her pain meds just to get the pain  manageable so she could be released, or she could be admitted  as a patient and as a result she would receive higher doses medication that would rapidly diminish her quality of life, and thus, slowly helping her pass. My question is, what medications was this doctor speaking of that would robb her of her life, and could these medications really do this? [/INST] Sorry to hear that your mother is suffering frm advanced stage gastric cancer.Advanced stage gastric as your mother is suffering is  very painful. Pain and other symptoms are usually manged in advanced stage gastric cancer (who are poor candidate of chemotherapy) are managed by pain medication and other supportive measures.Second option as discusedd by your ER doctor is probably of palliative chemotherapy which controls the pain by reducing tumor burden.But chemotherapy is as a whole in this advanced cases have lots of side effects.. which may deteriorate your mothers health. whether she is a candiadate of palliative chemotherapy is  better judged by oncologist/palliative care consultant at your hospital. </s>
