Britsh researchers have made strides in understanding the genetic make up of tumours. The research has found that in lung and skin cancers as the tumours grow and spread they carry biological "flags". These flags can be used by as markers by the immune system to detect which cells should be attack.
The flags appear as proteins on the surface of only cancer cells. It is thought that these flags can be used as targets for exciting new therapies. These treatments will harness the immune system in order to combat the cancer cells. Charles Swanton, who led the research said the discovery of these surface proteins shared by all cancer patient's cells may provide an "achilles heel" for future therapies.
