Brakyterapia

Brakyterapia is a form of radiation therapy used in the treatment of cancer. The term "brakyterapia" is derived from the Greek words "brakys," meaning short, and "therapeia," meaning treatment. It involves the use of radioactive sources that are placed directly into or near the tumor, delivering a high dose of radiation over a short period. This approach is particularly useful for treating cancers that are difficult to reach with external radiation therapy, such as those in the head and neck, prostate, and gynecological areas.

The radioactive sources used in brakyterapia can be in the form of seeds, wires, or catheters, depending on the specific treatment plan. These sources emit radiation that is absorbed by the tumor cells, damaging their DNA and inhibiting their ability to divide and grow. The treatment is typically administered in a single session or a series of sessions over a few days.

Brakyterapia is often used in conjunction with other forms of cancer treatment, such as surgery and external radiation therapy. It is particularly effective for localized cancers that have not spread to other parts of the body. The benefits of brakyterapia include its ability to deliver a high dose of radiation directly to the tumor, minimizing damage to surrounding healthy tissues.

However, brakyterapia also has potential risks, including the possibility of complications related to the placement of the radioactive sources and the potential for late effects, such as fibrosis or necrosis, in the treated area. As with any form of cancer treatment, the decision to use brakyterapia is made on an individual basis, taking into account the patient's specific medical condition, the stage of the cancer, and the potential benefits and risks of the treatment.
