It is not clear if cryosurgery improves the quality of life and mortality from prostate cancer compared to radiation therapy. [15] Potential adverse effects associated with cryosurgery include urinary retention, incontinence, and pain in the perineal region, penis, or scrotum. [15] Impotence occurs up to ninety percent of the time.
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
Radiation therapy or radiotherapy (RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator .
LDR prostate brachytherapy (seed or line source implantation) is a proven treatment for low to high risk localized prostate cancer (when the cancer is contained within the prostate). [ 4 ] [ 5 ] Under a general anaesthetic, the radioactive seeds are injected through fine needles directly into the prostate , so that the radiotherapy can destroy ...
Radiation therapy is used mainly in the treatment of cancer. Radiation therapy can be used to cure, care or shrink tumors that are interfering with quality of life. Sometimes radiation therapy is used alone; other times it is used in conjunction with chemotherapy and surgery. For people with brain tumors, radiation can be an effective treatment ...
Patients receiving treatment for prostate cancer and cancer of the cervix receive lethal doses of radiation. [11] [12] 13 Radiotherapy accident in Costa Rica: 1996 114 patients received an overdose of radiation from a cobalt-60 source that was being used for radiotherapy. [13]: 299, 303 11 Radiotherapy accident in Zaragoza, Spain 1990 December
