Brachytherapy for Treatment of Mesothelioma

Brachytherapy is a form of radiotherapy and is an advanced form of treatment for mesothelioma. It has been used for over a century for the treatment of mesothelioma.

Radiotherapy is used to treat mesothelioma by ionizing radiation, thus killing cancer cells. Radiotherapy can be performed internally or externally. When radiotherapy is performed externally the radiation is put into the body from an object outside the body, which is usually called a linear accelerator.

When radiotherapy is performed internally radiation is put inside the body. Internal radiotherapy can also be called brachytherapy. "Brachy" comes from the Greek word for "short range." The radiation is put into the body at short range, thus, brachytherapy. Some other names for internal radiotherapy are sealed source radiotherapy, seed implantation radiotherapy or endocurietherapy.

The radiation is placed either inside the cancer source or very close to it. The radiation that is placed inside emits radiation killing the cancerous cells but can only kill up to a one inch diameter, so the radiation must be placed close to the cancerous site.
