Biological and photodynamic therapy to treat skin cancer
The goal of biological therapy is to try to help the body fight cancer. In biological therapy, substances produced by the body itself or manufactured in a laboratory are used to boost, guide or restore the body's natural defences against the disease. Biological therapy is also known as biological response modifier (BRM) therapy or immunotherapy.
In photodynamic therapy, a certain type of light and special creams are used to eliminate cancer cells.
