An old acquaintance, the MYC oncogene, seems to be the most responsible for cancer cells hiding from the immune system and can continue to develop. This ally of cancer, according to a study published in "Science", helps tumor cells survive in hostile environments by increasing the expression of two proteins that hinder the ability of the immune system to destroy tumors.

The results, say researchers at Stanford University (USA) suggest that future therapies aimed at suppressing MYC may help promote an immune response against tumors and may eliminate them.
