Internal radiation therapy is a type of internally-administered radiation therapy, which fights cancerous cells through radioactive materials placed within the body. There are two main forms of internal radiation therapy, brachytherapy and systemic radiation therapy.
- Brachytherapy is a type of internally-administered radiation therapy, which fights cancerous cells through radioactive materials placed within the body. In brachytherapy, radioactive isotopes are sealed in tiny pellets or “seeds”, which are placed in patients’ bodies near tumorous growths. As the isotopes decay naturally, they give off radiation that damages nearby cancer cells.
Several brachytherapy techniques are utilized at Tallahassee Memorial including the GammaMedplus iX High Dose Rate Afterloader System and MammoSite Radiation Therapy System, a unit which may allow treatment of early-staged breast cancer in a shortened timeframe. Tallahassee Memorial physicians also use brachytherapy to treat prostate, cervical and ocular cancer.
- Another form of internally-delivered radiation therapy is called systemic radiation therapy. In this method of treatment, patients swallow or receive an injection of radioactive substances, which target and attack cancerous cells.
