A new treatment has been developed to treat lung cancer. Lung cancer is one of the most common form of cancers and responsible for a quarter of all cancer deaths. The treatment consists of a combination of two drugs. In animal experiments, it seems to be much more efficient than the treatment by only one of the drugs in the majority of lung cancers. It works by blocking two proteins important for the survival of the cancer. The treatment has fewer side effects than traditional chemotherapy as well.
