What Is Proton Therapy?
Proton therapy is an advanced form of radiation therapy that uses positively charged particles (protons) to precisely target and destroy cancer tumors while minimizing damage to surrounding healthy tissues and organs.
Remarkable Precision. Fewer Treatment-related Complications.
These are the defining features of proton therapy. By delivering radiation with a high level of accuracy, proton therapy reduces the risk of harmful side effects compared to traditional radiation. It is often recommended for patients with complex tumors, tumors that have returned after prior treatment, and children with cancer.
How Proton Therapy Works
At the New York Proton Center, patients receive pencil beam scanning, the most advanced and precise type of proton therapy available today.
As the name implies, pencil beam scanning uses an extremely narrow proton beam to “dot” radiation directly onto the tumor. This process is repeated layer by layer, similar to painting with the tip of an incredibly fine brush, allowing for highly controlled and targeted treatment.

The Most Precise Proton Therapy Available
Not all proton therapy is the same. Many proton centers use “volumetric” beams that deliver a fixed amount of energy to the entire tumor area, which may expose more healthy tissue to radiation. At the New York Proton Center, pencil beam scanning delivers intensity-modulated proton therapy (IMPT), widely considered the most advanced form of proton therapy. IMPT allows clinicians to adjust radiation dose levels within different parts of the tumor, improving precision and effectiveness while further limiting exposure to nearby healthy tissues.
This advanced approach is especially important for tumors located near critical areas of the body and supports highly personalized treatment planning.
Benefits of Proton Therapy
Because of its precision, proton therapy offers several important benefits compared to traditional radiation:
– More accurate tumor targeting
– Reduced exposure to healthy tissues
– Lower risk of certain side effects
– Potential for improved quality of life during and after treatment
Proton therapy is particularly valuable for treating tumors that are:
– Irregularly shaped
– Located near critical organs or structures
– Found in areas such as the brain, spine, head and neck, lungs, chest, abdomen, and pelvis
– Recurring following prior treatment
Patients interested in this treatment can speak with a specialist to determine whether proton therapy is an appropriate option.
Proton Therapy vs Traditional Radiation
Both proton therapy and traditional radiation therapy are effective cancer treatments, but they work in different ways. Traditional radiation uses X-rays that pass through the body, which can affect both the tumor and surrounding tissues.
Proton therapy, on the other hand, delivers radiation that stops directly at the tumor site, reducing unnecessary exposure to nearby healthy structures. This difference makes proton therapy an important option for certain patients, particularly when precision is critical.
Frequently Asked Questions
What is proton therapy used for?
Proton therapy is used to treat many types of cancer, including tumors in the brain, spine, lungs, head and neck, prostate, breast, and pediatric cancers.
Is proton therapy safer than traditional radiation?
Proton therapy may reduce exposure to healthy tissues and organs compared to traditional radiation, helping lower the risk of short- and long-term side effects. Radiation oncologists consider several factors to determine whether a patient will benefit from proton therapy.
How does proton therapy differ from traditional radiation therapy?
While both are forms of radiation treatment, proton therapy uses positively charged particles that deliver energy directly to the tumor, while traditional radiation uses X-rays that pass through the body.
Who is a good candidate for proton therapy?
Patients with tumors near critical organs, complex tumors, recurrent cancers, or pediatric patients may benefit most. A radiation oncologist can help determine eligibility through a consultation.
