A recent study, published in Nature Communications by King’s College London researchers, has identified a novel mechanism associated with skin damage that initiates tumor formation. The researchers describe an innate detection of bacteria by the cells of the immune system during the development of skin tumors.

When cancer spreads, it’s called metastasis.

Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
