thanks, starlight1968sg. I’ve heard of some ways to increase patients organism after the chemo, like healthy diets and regular excersises. Have you had any experience with these kinds of supplementary treatment?

Recently I've read a study about how chemotherapy can be harmful for patients with breast cancer (here, under the name \"Radiation therapy leaves the most dangerous cancer cells ‘alive’\": http://paseka.us/alternative-cancer/). It says, that radiation therapy for breast cancer kills approximately the half of cancer cells, but the remaining breast cancer cells are being transformed into even more aggressive and dangerous cancer stem cells that are far more resistant to treatments. I it true? Have any of you read or heard anything about it? One of my distant relatives have a stage 4 breast cancer, it's pretty bad, and I am looking for any possible information on the subject.
