# Brachytherapy

An advanced form of radiation therapy, brachytherapy delivers radiation from the inside out. Brachytherapy uses radioactive seeds (or pellets) which are placed into a tumor, where they deliver a continuous dose of radiation to destroy cancer cells.

With brachytherapy, thin catheters are insert into the tumor. The radioactive seeds are delivered through the catheter under image guidance (CT or ultrasound) and left in place.

Though it is not appropriate for all cancers or all patients, brachytherapy has the advantage of being extremely precise. Since the radioactive source is literally placed inside the tumor, the risk of damage to nearby healthy tissue is minimized.

The radioactive seeds remain in place for a predetermined period of time and then are removed. They are not left in the body indefinitely.

Brachytherapy is most often used to treat:

• Breast Cancer
• Gynecological Cancer
