Your mother has developed metastatic rectal cancer which is very advanced stage of disease. Although this stage is not not curable it is treatable. Multiple chemotherapy drugs are used  in combination in this stage.Depending on her general condition and tolerance doctors will prescribe her anti-cancer medication. These may  include the chemotherapy agents 5-FU , irinotecan, oxaliplatin, and capecitabine  or modern  targeted therapies bevacizumab and cetuximab. Along with anti-cancer medicine she requires palliative care for management of symptoms she might be having like pain,nausea,abdominal distension etc. Regards </s>
