Proton Therapy vs. X-rays

Proton Therapy vs. X-rays

Radiation therapy with X-rays is a valuable treatment option for many cancers but its role is limited by the risk of damage to organs adjacent to the tumor site that can sometimes be life threatening. This is because X-rays are highly penetrating, imparting ionizing energy to cells as they pass through the skin and tissues. This is not always a limiting factor: in the case of prostate cancer, for example, treatment options include radical prostatectomy, standard radiation therapy and proton therapy.

While X-ray delivers radiation not only to the tumor but also to healthy organs and tissues surrounding the tumor, proton beams can release its maximum energy at the tumor. It attacks DNA in the core of the cancer cells, making the cancer cells unable to reproduce which then followed by a gradual disappearance of the tumor. Proton therapy is often considered the most advanced form of radiation available today.  It results in less radiation, dramatically minimizes serious side effects and lowers the chances of secondary cancers.

Why Proton Therapy

Unlike standard radiation or surgery, proton therapy is an extremely precise form of treatment for certain cancers. Proton beams are a flow of particles generated from hydrogen gas. By using an accelerator, a synchrotron accelerating these particles to near the speed of light, making it able to
precisely target cancer. With that said, proton beams have the ability to focus and affect cancer lesions with minimal impact on surrounding muscle and tissues, thus minimizes detrimental side effects on healthy tissues.

Benefits of Proton Therapy

  • Unmatched Precision – Proton beams can target the tumor and inflict damage on cancer cells.
  • Reduced Side Effects – Precision treatment minimizes serious side effects
  • Suitable for Complex Conditions – Prostate, lung, liver, bile duct, pancreas, head and neck, esophagus, breast and
  • Lower Chances of Secondary Tumors – Reduces the risk of radiation-induced secondary cancers
