Staphylococcus epidermidis bacteria are part of the normal skin microbiome
Skin bacteria protects against cancer

Researchers have found that a bacteria stain that lives on the skin might protect against skin cancer. The bacteria, S. epidermidis, secrete the chemical substance 6-HAP which prevents cancer formation on the skin of mice that had been exposed to cancer-causing ultraviolet rays (UV). Further research should find out how 6-HAP is produced and whether it can be used to protect against cancer caused by overexposure to UV radiation from the sun.
