Cancer tumour genetics reveal possible treatment revolution

guardian 5

A landmark discovery into the genetic makeup of tumours has the potential to open a new front in the war on cancer, delivering potent therapies that are tailored to individual patients, scientists have said. The breakthrough comes from research into the genetic complexity of lung and skin cancers which found that even as tumours grow and spread around the body, they carry with them a number of biological “flags” that the immune system can be primed to attack. Because the flags, which appear as surface proteins, are found only on cancer cells, they provide what scientists described as “exquisite targets” for new therapies that draw on the power of the immune system to combat cancer.
