Two Types Of Radiation Therapy For prostate cancer

Radiation therapy is one of the many treatment options prostate cancer individual has to choose. This is a technique that uses high energy x-rays or other types or energy. This aims to kill the cancer cells or to keep the cancer cells from growing back again.

There are two known types of therapy using radiation which may be used to treat prostate cancer. One is the actual external radiation therapy (XRT) which utilizes a machine or perhaps a medical equipment outside of the body and is capable of sending rays. The other one is the internal radiation therapy which uses radioactive substance as with the brachytherapy.

An example of an external radiation therapy is the IMRT or the Intensity Modulated Radiation Therapy in which multiple beams coming from a variety of directions are used to focused on the prospective area- the prostate gland. The doctors were able to adjust the intensity and the strength of the supports based on the computerized program prior to the operation. This is important so that more radiation will blast the actual tumors or the cancer cells and less is delivered to the nearby organs like bladder and rectum.

In Brachytherapy, some small radioactive capsules which they call “seeds” tend to be implanted into the cancerous prostate glands. These seeds will then emit radiation to the surrounding areas aiming to kill all the malignant tumors. Men that are diagnosed with prostate cancer at stage T1 or T2 are said to be candidate for this type of treatment.

The oncologist first creates a 3-D grid map area of prostate using TRUS or Transrectal Ultrasound. The pc will then calculates the volume of the gland; determine the number of seeds that will be implanted and also to figure out the location of the implantation.

The procedure would take about 50 to 60 minutes to finish and usually on an outpatient basis. The patient is only given a regional anesthesia prior to a needle with about One hundred or more rice-sized seeds are inserted to a predetermined area. These seeds contain the radioactive isotopes of palladium 103 and iodine 125 capable of emitting rays for a period of three months. These isotopes will become inert after the three month period.

There are side effects the actual men are suffering when given radiation. Impotence as well as urinary system problems is the most common ones. Men who went through the radiation therapy have a greater risk of anal cancer and also bladder cancer. A small number of patients who have undergone brachytherapy especially those over the age of 70 will also be noted to have experience erectile dysfunction or incontinence.

With the technologies of ours today, period will come the percentage of men is going to be fully recovered after the rays or other treatment options they undergone. Gather more information through visiting http://www.ProstateRadiation.org.
