Cancer Research Institute: Chemotherapy Makes Tumors Grow
Scientists at the Cancer Research Institute in Russia have discovered that chemotherapy can actually stimulate evolution of a tumor, rather than diminish it as previously thought.
Scientists studied chemotherapy patients with breast cancer and analysed biopsies of the cancer as they prepared for surgery. In 23% of the women scientists found a new tumor formation under the influence of chemotherapy.
