Hi- Let me tell you a bit about myself. I have a type of cancer that has recurrences. So I have had 4 lung cancers over a period of 21 years. I just found out that a new lesion has changed and it might be my 5th. I wont know more until Feb. when I have another CT scan. There are many types of lung cancer. Do you know the type that your mom has? Before we get into my diet I am concerned about your mom taking Oncotame. This is an herbal remedy for metastatic cancer. Has your mom's cancer spread to another part of her body? Was Oncotame prescribed by her doctor? Are there plans for further treatment at all, or has your mom chosen not to do anything but control her symptoms such as pain. My diet isn't very special. I eat in moderation- 4 times a day with protein, starch and fruits and vegetables and nuts/seeds. I drink lots of water. I quit smoking 21 years ago and I really only drink alcohol when I go out to dinner, which isn't as often as I would like. lol. There aren't any special "cancer" diets, really there aren't. We can only strive to stay as healthy as we can. I also walk, and do weights. Even with a very healthy person diet alone wont keep someone well, they have to move. However if your mom has chosen not to have any treatments and ride out the cancer than if I were her I'd eat anything I could tolerate, and anything I'd want.
