Tratamiento de Braquiterapia (Semillas radioactivas) en Perú

Brachytherapy that involves using radioactive seeds is known as Permanent Brachytherapy. The radioactive seeds are placed in or near the tumor and are left there permanently. After many months, the radioactivity level of the implants reduces to nil. The seeds are inactive and remain in the patient’s body without any lasting effect.

Brachytherapy is used to treat cancers of the prostate, cervix, head and neck, skin, breast, gallbladder, uterus, vagina, lung, rectum, and eye.

How is Permanent Brachytherapy performed?

• A needle containing radioactive seeds is inserted into the tumor.
• The needle is removed and the radioactive seeds are placed inside the patient’s body.
• The physician may use X-rays and CT scans to position the seeds in the correct place.
• Other imaging tests may also be performed after the seeds have been implanted to verify the placement of the radioactive seeds.

• Blood tests
