Even more alarming is the fact that radiation treatments can cause some cancer stem cells. They can behave like regular cells, but develop into tumor-forming cells. Scientists are not sure how this happens to date. Some doctors are looking to reduce the amount of radiation therapy given to patients in light of this evidence, but many more should consider natural therapies that do not create a ‘false’ healing which cause cancers to grow back with even greater force. Yet another study in the journal Stem Cells found that ionizing radiation reprogrammed less malignant breast cancer cells into iBCSCs. Cancer stems cells are especially non-responsive to chemo and radiation treatments, and this is why these ‘medicines’ often do not work. “Breast cancers are thought to be organized hierarchically with a small number of breast cancer stem cells (BCSCs) able to regrow a tumor while their progeny lack this ability. Recently, several groups reported enrichment for BCSCs when breast cancers were subjected to classic anticancer treatment. However, the underlying mechanisms leading to this enrichment are incompletely understood,” the study says. onlinelibrary.wiley/doi/10.1002/cncr.27701/full
