Quote:Radiotherapy has been shown to increase the survival and self-renewing capacity of these breast cancer initiating cells by up to 30-fold, which means that while a radiation treatment may initially regress a tumor's volume/mass, it may actually be selecting out the more radiation-resistant and aggressive subpopulation of tumor cells which ultimately lead to higher malignancy. This promotion of self-initiating cancer cells is also true for chemotherapy, of course.
This is exactly what has happened to my b-i-l the cancer in his lungs has stalled but malignant cells have moved into his shoulders, neck and towards his brain. So what are they doing? Giving him more chemotherapy. Once you get cancer, you're just a vehicle for industry profits.
