Prostate Cancer Radiation Seeds

It is a type of internal radiotherapy. In theory each radioactive seed blasts a targeted area of tissue ultimately destroying the prostate.

There are two types of.

Prostate cancer radiation seeds. High dose seeds require a short hospital stay are temporarily moved through very small tubes placed in the prostate. Only each seed irradiates a small volume of prostate tissue and therefore many seeds have to be placed throughout the prostate to cover the entire gland and the cancer site. The type of seed determines the amount of radiation released by the seeds and the duration of treatment.

The terms brachytherapy or internal radiation therapy might also be used to describe this procedure. During the procedure radioactive iodine 125 or i 125 seeds are implanted into the prostate gland using ultrasound guidance. The radiation has a very short half life is not harmful to anyone you may come in contact.

Radiation from the seeds travels a very short distance so the seeds can give off a large amount of radiation in a very small area. Radiation therapy is one method of destroying cancer cells. Usually around 100 seeds are placed but this depends on the size of the prostate.

Radioactive seeds are sometimes placed in diseased tissue on an outpatient basis or during an operation. So that the cancer gets a high dose but nearby tissues and further away the levels of radiation are low. In recent years the seeds are strung together to avoid seed movement outside the prostate could migrate to other parts of your body.

During interstitial brachytherapy grenade like radiation seeds are inserted directly into the prostate tumor. Prostate cancer brachytherapy can be done with different types of radioactive seeds. In practice however it hasn t been that simple.

With brachytherapy your doctor puts the radioactive source or seeds as close to the cancer as possible. Although the seeds remain in your prostate for the rest of your life the amount of radiation released by them is low to begin with decreases with time and. This limits the amount of damage to nearby healthy tissues.

Because of the low x ray radiation energy released radiation exposure to adjacent normal organs is reduced. Permanent radioactive seed implants are a form of radiation therapy for prostate cancer. Prostate brachytherapy involves placing radioactive sources in the prostate gland where the radiation can kill the cancer cells while causing less damage to healthy tissue nearby.

The seeds slowly release a low level of radiation into the area of the prostate over a few months. Radioactive seed implants are a form of radiation therapy for prostate cancer brachytherapy or internal radiation therapy are also terms used to describe this procedure. They may be used to keep the radiation dose focused on a specific organ or they may be placed in areas where it is difficult or impossible to assure complete surgical removal of all the diseased tissue during an operation.
