How old is your mom TS? My mom passed away last year due to colon cancer stage 4. She undergo chemo for about 1 1/2 years. It was dreadful. I strongly suggest avoiding chemo if your mom is about 50+ as her body cells are not able to regenerate fast enough.

Try opting for traditional method. You can try tung shin hosp and opt for their natural herb remedy.

Lastly, do spend as much time as possible with her. Keep her motivated and encourage her at all times. She really needs it. Stay strong TS!
