My mom is 58 years old, she had colon cancer 8 years ago, she was clear for 7 years and in the last year has had a tumor form in her pelvis and spots on her lungs, both biopsied and results showed the same as her colon cancer. Yesterday she was diagnosed by x-ray of having stomache cancer, no biopsy yet to see if it is the same cancer, but assuming it is what is her chances of survival? She has lost 75 pounds in a year, 25 or more in the last 2 weeks while hospitalized. She has needed a blood transfusion, and went into renal failure 2 weeks ago. (she only has one kidney) She cannot eat solid foods, she will vomit, she has no appetite and is nautious all the time even with anti nausea meds. She is in extreme pain some days. The other night they maxed her out on narcotics, couldnt give her anymore without it being unsafe.
also she has had a colostomy bag for the past year because of the pelvic tumor.
so how bad does this sound and what is her treatment options and chances?

Doesn’t your body cleanse itself of environmental toxins (pesticides, food additives, excess minerals and vitamins) itself? Is a store-bought cleanse—colon, kidney, liver, lungs, vascular, bowel, etc. cleanse—-really necessary?
Advocates of these type(s) of cleanses claim that excess toxins in the body cause weight gain, skin problems such as acne, depression, memory loss, and all sorts of other ailments.

Can someone with knowledge and experience (only people with true insight please–no uninformed responders) please help me find an answer to this?
