The treatment had made use of radiation therapy since 1915. During those times the results have not been very acceptable because the radiation rays did not infiltrate deeply in irradiating the cancer cells and instead to skin tumor and morbidity. However, in 1980 equipments such as linear accelerators were utilized by oncologists. These helped to get to targeted areas better and added the pace of the elevated energy elements being delivered.

There are three types of radiation which rely on the kind of high energy elements being delivered in the treatment of cancer.

• 3D-CRT (3 Dimentional Conformal Radiation Therapy) - uses subatomic electrons on aiming elevated energy particles/waves some photon radiation

• Neutron Beam Therapy which uses neutrons

• Proton Beam Therapy which uses protons

Fractionated radiation cure for cancer

This external ray radiation is delivering little doses of radiation to targeted part of the patient's body over 9 weeks or more, relying on the case. The normal and healthy prostate cells can recover easily from these little doses rays while the tumor cells can not recover.

Patients with tumor in the prostate who want to be treated through external radiation therapy must have the following: 6 or lower Gleason score; 10 or lower PSA scale; Contained or localized tumor in prostate gland; No abdominal mark tissue because of previous surgical operation.

PSA scale of ten or lower and Gleason score of six or lesser means that tumor is enclosed in the prostate gland itself and was not able to scatter in the tissues or organs around. Medication for prostate tumor such as IMRT and 3D-CRT are good because they destruct the tumor in the prostate gland while the organs and tissues surrounding it are unaffected and unattached. If the tumor had spread already then the danger is greater in the surrounding area.

When the patients have scar tissues in the abdominal region because of surgical operations done earlier, the intestines and colon will be open to extra radiation. All patients who have undergone radiation cure for prostate cancer cannot be given again.

Salvage medication for prostate cancer.

This kind of cure involves brachytherapy. However, radiotherapy is not recommended as salvage treatment for cancer of the prostate if brachytherapy is not successful because prostate gland was treated already of elevated doses of radiation. Radiotherapy is given to patients with benign hyperplasia of the prostate.

Cryotherapy is also a cure for tumor of the prostate that is suggested as salvage treatment when radiotherapy is not successful. Cryotherapy involves the chilling of the tumor cells from the prostate gland to destroy them.
