My question is for my mother. My mother had colon rectal cancer 3 years ago. She went for a critical surgery and removed the colon and a few lymph nodes. My mother is now 80 years old. She is slowly recovering since the surgery. She did not have to go for chemo or radiation. She has been careful with her diet since then. She eats more vegetables and fruits than before. She went back to PET/ CT scan every year and the result is always “Clear”. She and her family does not have cancer gene. I wanted to know whether her diet can be a great change for her life. Is there any other factor ? I would appreciate your advice how to live on to keep the same result when my mother goes for PET scan. Thank you.
