Proton Therapy for Breast Cancer

When treating breast cancer, proton therapy can be combined with treatments like surgery and chemotherapy to reduce the risk of damage to your heart and lungs. Proton therapy is one of the world’s most advanced forms of radiation therapy. It precisely targets the tumor and avoids unnecessary radiation to nearby healthy tissue and organs, resulting in a lower risk of side effects and improved quality of life.

If radiation is part of your treatment plan, it is important to learn more about proton therapy. The precision of proton therapy means patients have a lower risk of long-term side effects, including heart disease, and usually experience little to no impact on their energy level during and after treatment.7,8

Proton therapy is a more precise form of radiation therapy that is an effective treatment option for many breast cancer patients. It is especially beneficial for left-sided breast cancer, as the cancer is close to critical structures like the heart, LAD (left anterior descending artery), and lungs. When treating breast cancer, proton therapy is often used in conjunction with other modalities, such as surgery and chemotherapy.

Proton Therapy for breast cancer has many compelling benefits:

  • Treatment is provided in an outpatient setting
  • Little to no impact on patient’s energy level
  • Minimal downtime during treatment
  • Reduced risk of side effects, including heart disease, especially for left-side breast cancer6

We believe the quality of your life during and after treatment matters. That’s why it’s important to be your own health advocate and understand all of your treatment options, as well as the possible side effects of each.

Make Protons Part of Your Plan

It is common for a breast cancer treatment plan to include multiple methods of treatment. Depending on the specific diagnosis, doctors may recommend a variety of treatment options, including surgery, chemotherapy, and radiation therapy. These modalities are often used in conjunction with one another.

When radiation is recommended as part of your treatment plan, patients should consider the remarkable outcomes and advantages proton therapy offers compared to traditional x-ray radiation.

Proton therapy for breast cancer reduces the risk of side effects by delivering significantly less radiation to surrounding organs like the heart and lungs, compared to traditional radiation (x-ray/IMRT).

Why Choose Protons Over X-rays?

Proton therapy and traditional radiation are similarly effective when it comes to destroying cancer cells. However, protons have distinct characteristics that allow the radiation beam to precisely target the tumor. This avoids unnecessary radiation to nearby healthy tissue and organs, ultimately reducing the risk of short-term and long-term side effects.

Research shows proton therapy has many clinical benefits compared to traditional radiation therapy.

  • 88% less radiation dose to the heart for left-side breast cancer.1,2
  • 44% reduction in clinically significant radiation doses to the lung.2
  • 90% of partial breast irradiation cases result in good to excellent cosmetic outcomes at 5 years.3
  • Well tolerated – Less than 4% serious side effects (grade 3) in locally advanced breast cancer.2

How Proton Therapy Works

When protons enter the body, most of their energy is deposited at the targeted tumor and does not continue beyond that target. This unique behavior allows protons to destroy cancer cells while minimizing damage to nearby healthy tissue and critical organs. This is different from traditional radiation, in which x-rays deposit more radiation before their target, then continue delivering radiation beyond the tumor.

The image above shows the difference between protons and x-rays (IMRT). The goal of treatment is to deliver the proper dose of radiation directly to the tumor, while limiting the amount of exposure to surrounding healthy tissue. This is illustrated by the orange area, which represents proton therapy. On the other hand, the gray area shows how x-rays use IMRT to deliver radiation. Much of the healthy tissue in front of the target receives unnecessary radiation, and by the nature of x-rays, more unnecessary radiation is delivered beyond the tumor.
