Cancer Research: How the tumor escapes the immune response ♦ Treating breast cancer with progesterone could aid survival ♦ Cancer drug 49 times more potent than Cisplatin

Cancer drug 49 times more potent than Cisplatin A new cancer drug has been found to have effectiveness for ovarian and bowel cancer that is 49 times as potent as Cisplatin. The key to this new drug, researchers report, is that it can shut down a cancer cell's metabolism. They add that the new drug could be cheaper to produce and less harm to healthy cells than alternative therapies.
Breast cancer routinely over diagnosed in Norway For every life saved by Norway's Breast Cancer Screening Program, five women are over diagnosed, and have to go through an operation to remove a tumor that otherwise never would have caused problems.
Disrupting cells' 'powerhouses' can lead to tumor growth A  study implicates defects in mitochondria, the energy-production centers of cells, as playing a key role in the transition from normal to cancerous. In their report, researchers note that looking for defects in cytochrome oxidase C could be a biomarker for cancer screening.
Treating breast cancer with progesterone could aid survival A special technique where breast cancer cells are “rescued” for research has been developed by researchers. Coupled with advanced scientific technologies, this has provided a unique insight into the hormone regulation of breast cancers, which is expected to lead to new treatments for the disease.
Lymphoma: How the tumor escapes the immune response Natural killer cells of the immune system can fend off malignant lymphoma cells and thus are considered a promising therapeutic approach. However, in the direct vicinity of the tumor they lose their effect. Scientists have now elucidated which mechanisms block the natural killer cells and how this blockade could be lifted.
