Proton Therapy my personal experience

I have tried the Proton Therapy radiation to destroy a tumor located near my removed prostate. 1st proton therapy was with Loma Linda Medical Center. These are 7th Day Adventists who reject evolution but have graduated 10,000+ Doctors. Their idea of Proton therapy is using passive scatter which has only a large pattern. There is much healthy tissue damage. Their system is the First iteration of proton technology and is potentially more damaging than the X-ray systems it is desgned to replace. X-ray systems are known as IMRT Image modulated radio therapy. They also want PCa patients with a Gleason score over 7 to also get IMRT. This means IMRT with a Proton boost. This is old school and leaves the patient with many of the problems of IMRT. It CAN'T be repeated because of x-ray damage to healthy tissue. The passive scatter also misses much of the tumor leaving the patient with cancer. My last colonoscopy showed radiation burns on my colon where the proton beam attacked the tissue. It should be noted that they didn't even aim at my tumor because it was too high for the rays to penetrate. That was an extreme waste of time and $. I don't know how they get away with such fraud. 2nd Proton Therapy was in 2014 at Scripps Proton Therapy Center in San Diego, Ca. They are using the Varian Proton Therapy system. This system uses a pencil-beam raster scan system developed with PSI in Switzerland. It can be called IMPT. They can target a tumor to a pencil point and move the beam back and forth to get at a deeper part of the tumor. They are currently radiating tumors inside the prostate without surgery. My PSA reading is down but so is my Testosterone (T) level so not sure if this is working yet. I will be taking PSA and testosterone reading for the next 5 years. (Hormone depleting therapy also works by lowering the gonad T level so not sure which is at play in my case.) I will know if the PSA stays down when (if) the T level goes up. Proton (charged particles) or hydrogen atoms with stripped electron are superior to x-rays. 1. x-rays do the most damage just inside the skin and keep on damaging until they exit the body. Protons deliver most of their energy just before they stop (Bragg's peak). This precision is a major tissue saving feature. X-ray damaged healthy tissue can not be radiated with x-rays again. Proton therapy can be used to in salvage radiation on regrowing tumors. 2. X-rays have very little mass (weight) (protons have 1800X the mass) (Having more mass means more destructive power). 3. X-rays tend to destroy only one of the two strands of DNA. Cells are good at repairing single-strand breaks. Note: cancer cells have a problem repairing cells, but they can use the damaged cells to further metastasis. (Protons destroy BOTH strands of DNA meaning the cell will apoptosis when trying to reproduce.) 4. X-rays need oxygen to enhance their tumor destroying capacity. Cancer cells have a notoriously poor oxygen supply so the drugs given to improve their effectivity also helps the cancer to survive and grow. 5. X-ray treatment centers are located everywhere and Doctors who prescribe may own the equipment. This conflict of interest leads to many false excuses as to why one should use x-rays vs protons. An example: it has never been tested against x-ray equipment (clinical trials). Neither was the system called IMRT (x-ray) which replaced the previous system. It is too expensive: Provenge cost $93K(factory)+$40K(Doctors) much more then proton therapy and it only prolongs a patient's life by months! Doctors make 50% of their profits from the drugs they prescribe. There is no profit to the prescribing Doctors with protons. (They complain that they are not compensated for the time it takes to explain why protons are better this is also used as an excuse as to why they do not recommend clinical trials in general.)
