Brachytherapy: A Precise Approach to Cancer Treatment
Brachytherapy is a specialized form of radiation therapy that involves placing radioactive sources directly inside or next to a tumor. Unlike conventional external beam radiation, which delivers radiation from outside the body, brachytherapy allows for a highly targeted approach. This precision minimizes damage to surrounding healthy tissues while maximizing the dose to the cancerous cells.
The procedure is commonly used to treat cancers of the prostate, cervix, breast, and head and neck regions. Depending on the type and location of the cancer, brachytherapy can be administered in different ways. Interstitial brachytherapy involves placing radioactive seeds directly into the tissue, while intracavitary brachytherapy uses a device placed within a body cavity, such as the uterus. Another method, surface brachytherapy, targets skin cancers with radiation delivered through applicators placed on the skin.
One of the significant advantages of brachytherapy is its efficiency. Because the radiation…
