Proton Therapy Predictions...
The field of proton therapy is continuing to see explosive growth. In the past decade alone, technological advances have made proton therapy a more accessible, viable option for hospitals and radiotherapy centers. Moreover, clinical applications for proton therapy have evolved, enabling the treatment of a broad range of diseases...
Once limited to only a handful of cancer centers due to its expansive size and prohibitive cost, proton therapy hardware evolved in the 1990s to a smaller profile, making the technology more accessible. That said, the size of the equipment is still measurable, with a large footprint, presenting a substantial challenge to legacy radiation oncology departments…

Could proton beam therapy help more children?
Proton beam therapy is more specific, as the beams stop a certain distance into the body, unlike normal radiotherapy beams which continue indefinitely. Proton beam therapy therefore causes a lot less harm to the healthy tissue beyond the tumour.
Proton Beam is Losing Support
At first, proton beam radiation for prostate cancer appeared to be as brilliant a treatment as the pot of gold at the rainbow’s end. For proton beam therapy to have a future among prostate cancer patients, there will be an uphill battle for centers to prove its merits to insurance companies.
Targeting tumours with proton beam therapy
Proton beam therapy has been driven by cyclotron technology since it first used in 1932 by Ernest Lawrence at the University of California, Berkeley. This was followed in 1937 by the European cyclotron located at the Radium Institute, Leningrad and developed by George Gamow and Lev Mysovskii.

Proton beam therapy, offered in only two UK hospitals, precisely targets tumours, reducing damage to surrounding healthy tissue

For Cancer Centers, Proton Therapy’s Promise Is Undercut by Lagging Demand
Although most of the proton centers in the United States are profitable, the industry is littered with financial failure: Nearly a third of the existing centers lose money, have defaulted on debt or have had to overhaul their finances.
Is Proton Therapy Safer than Traditional Radiation?
Traditional radiation delivers x-rays, or beams of photons, to the tumor and beyond it. This can damage nearby healthy tissues and can cause significant side effects. By contrast, proton therapy delivers a beam of proton particles that stops at the tumor, so it’s less likely to damage nearby healthy tissues.
Petite Particle Accelerator: A Proton Gun For Killing Tumors
Since 1990, doctors have been regularly treating cancer patients using proton beams, which work similarly to radiation. Proton therapy is more precise, however, causing less harm to healthy surrounding tissues. Unfortunately, generating a proton beam requires a particle-accelerator facility that’s the size of an airplane hangar and costs more than $100 million to build.
Proton beam therapy for cancer in the era of precision medicine
The dosimetric advantage of protons results in a finite range with little or no exit dose and a smaller volume of normal tissue to be irradiated.
Proton Beam Therapy Sparks Hospital Arms Race
Hospitals are still racing to offer expensive new technology — even when it hasn't been proved to work better than cheaper approaches. Case in point: proton beam therapy, a high-tech radiation treatment for cancer.
Proton cancer centers continue to proliferate, despite shaky benefits and checkered financiers
On May 12, the South Florida Proton Therapy Institute issued a warning to its investors: It had a week’s worth of cash left and had to dip into a reserve fund to pay off debt.
Proton therapy a high-tech alternative to traditional radiation
Proton therapy is a high-tech alternative to X-ray radiation that offers greater precision to destroy cancerous cells and spare adjacent healthy tissue with fewer side effects. Proton therapy uses positively charged atomic particles, traveling up to two-thirds the speed of light, to fight cancer.
Proton-Beam Therapy for Cancer
Because traditional radiation therapy zaps everything in its path, doctors have to limit the dose in order to reduce serious side effects. Proton beams work differently, delivering a low dose of energy as they enter the body and then gradually increasing to a maximum when reaching the cancerous target. The dose drops to zero as proton beams exit the body. Because damage to healthy tissue is minimized, doctors can treat cancers with higher and therefore more-effective doses of radiation.
Proton-Beam Therapy for Cancer Gets Renewed Attention
Less costly, compact machines are rekindling demand from hospitals.
When Is Proton Beam Therapy Worthwhile?
It's impossible to know if proton beam treatment gave Kennedy more months of quality life. But it didn't give him what he probably wanted most -- time to see Congress enact a universal health care plan.
Zap! You're not dead
RADIOTHERAPY, the use of radiation zipping through the DNA of cancer cells to kill them or halt their reproduction, has always had the disadvantage of causing collateral damage to healthy tissue. But some forms of radiation are worse than others. One of the best is a beam of protons. Unlike X-rays, the standard radiotherapeutic tool, a proton beam can be tuned in a way that causes it to dump its destructive energy at a particular depth beneath the skin. This means it can destroy a tumour without damaging other tissue.

National Association for Proton Therapy
The National Association for Proton Therapy (NAPT) is an independent nonprofit organization founded in 1990 to educate and increase awareness about the clinical benefits of proton therapy. Proton therapy is one of the most advanced methods of radiation treatment available today due to its unique ability to allow radiation treatment doses to be delivered to cancerous tumors while minimizing radiation exposure to healthy tissues and organs.
