More than 192,000 new cases of prostate cancer are diagnosed every year, making it the third most frequently diagnosed cancer after lung cancer and breast cancer, according to MD Anderson.
Nearly all of these cancers originate in the gland cells of the prostate, but a small number of cancers begin in the tissue of the prostate.
Prostate cancer is known as a slow-growing cancer, and in many cases, doctors prescribe watchful waiting or active surveillance, especially in older men. There is a range of other treatments that doctors can use, and may use one type of treatment over another, depending on where the cancer is located, and research is continuing to develop new treatments.
According to The American Cancer Society, existing treatments include:
* Bone-directed treatments
* Vaccine treatment
* Chemotherapy
* Hormone therapy
* Surgery
* Cryotherapy or cryosurgery: This is used for cancers that are localized to the prostate. It involves the use of probes that freeze the tumor.
* High intensity focused ultrasound: This treatment heats the tumor to kill the cancer cells.
* Proton beam radiation therapy: With this therapy, small particles attack and kill the prostate cancer cells that have not spread.
