Metastatic Lung Cancer: She Refused Medical Treatment

Dear Dr. Chris,
 
Hi, my name is WSP, I would like to seek your advice on my mother's case.  My mother is 66 years old.  She is a lung cancer patient since first diagnosed in Sept 2007.
 
We declined any western medicine (chemo etc) as we have no confidence in the chemo.  Instead, we brought her to Zhu Hai China Cancer Rehabilitation Center for 3 months of herbal treatment. 

My mother is taking the Chinese herbal medicine from May 2008 till to date. Other than that, she is controlling her diet, eats light every day, talking multi-vitamins, doing 'Kok Ling' qi gong etc.  There was no medical checkup during the 3 years from 2007 to 2010.  Simply, my mother felt that it is stressful for her to do so.
 
Two months ago she has back pain and resulted in some difficulties in movements. We brought her for CT scan yesterday and I just got the report. We will be seeing the doctor on next Tuesday only.
 
I would like to bring my mother to see you but prior to that, I hope Dr Chris can kindly review my mother's report and inform me the best thing that I should do now. Next Tuesday, we are seeing the Oncologist. Honestly, I would like to decline any chemo treatment or radiotherapy for my mother. She is already so weak and low spirited.  I am worried that the drugs that they use will further damage  rather than improving!
 
We just hope that my mother will not suffer any pain and will further improve her quality of life.
 
I thank you in advance in your time and your assistance.  
Thank you very much.
