Treatment for prostate cancer by stage.

Dr. Ritesh Rathore
Hematology and Oncology 30 years experience
Quite a few: Early stage (cancer within prostate): robotic or open surgery, standard radiation; radiation seeds; cryosurgery. For cancer with local spread to nodes typically radiation and hormonal therapy is used. For recurring cancer or for spread to far organs; a sequence of therapies is used. Initially, a series of 3-4 hormonal drugs one by one, then immune therapy (provenge) and then chemotherapy.

Dr. Andrew Turrisi

Proof of cell: Phone link not yet in, microwaves are relatively safe, but radiation is in the electromagnetic spectrum and is a clear cause, and u-v light is part of the spectrum causing skin cancers. All seem to demonstrate direct links to dose and time of exposure. X-rays seem to have no threshold, but very low doses are very unliklely to lead to individual harm, but to a population, a small number will.

How come there are so many new drugs but we cannot find the cure for cancer?

Cancer is not: One disease, or one genetic chnge, but many. Drugs are poisons with side effects, and tumors are smart enought to learn to resist. Single genetic mutations are cured with miracle drugs. Many drugs now hope to keep cancers at bay and allow you to live with the cancer rather than obliterating it. The most fearsome of cancers is glioblastoma (brain tumors) and pancreas cancer. Few baby steps only.
