Which cancer is associated with Brachytherapy as a treatment option?

Brachytherapy is a form of internal radiation therapy where radioactive sources are placed directly within or very close to the tumor. This technique allows for a high dose of radiation to be delivered to the cancer while minimizing exposure to the surrounding healthy tissue. Prostate cancer is particularly well-suited for brachytherapy because the prostate is relatively small and well-defined in its anatomical location, making it easier to place the radioactive sources precisely.

In prostate cancer treatment, brachytherapy can be delivered as either low-dose rate (LDR) or high-dose rate (HDR) therapy. LDR involves implanting small seeds that emit radiation over a longer period, while HDR uses temporary implants to deliver a higher dose of radiation in a shorter time frame. Both methods have shown effectiveness in treating localized prostate cancer, improving survival rates, and reducing the risk of complications.

Other cancers listed may also use radiation therapy, but they do not typically utilize brachytherapy as a first-line treatment. Brain cancer often requires external beam radiation due to the complex nature of the brain's anatomy and the need for precision in targeting tumors while avoiding critical structures. Lung cancer, due to its larger size and location, is often treated with external beam radiation as well. Rectal cancer can use
