Recto vaginal fistula & CA Cervix.

Hello, My mother she is 555yrs age old previously she was diagnosed (5yrs)before CA Cervix Stage 1B2. 30 days radiation and 4 chemotherapy and 3 days brachytherapy(3D) was given. Now (CXR P/A View Digital) & (HRCT Thorax) CT scan had been done and report seems like cancer had spread over her left lungs. She is being surviving now vaginal discharge at present and stool is discharging through her vagina. Doctor's had suspected that her cancer is in final stage 4B and started treating her and last saturday they operated her and they fixed a IColastomy bag i mean they have diverted her rectum from her stomach and fixed a IColastomy bag.But the symptoms are still same, since for past 30days she is being admitted in hospital but still again stool is passing(discharging)from her vagina and little bit is discharging in her Icolastomy bag as well. Some times on a interval bleeding is also discharging from her vagina and inflammation is also causing internally when she is discharging urine.
