I WANT TO FIGHT BACK
WITH PROTON THERAPY

Maximum Treatment.
Minimum Side Effects.

California Protons, located in San Diego, is the only center in the state using clinically proven, revolutionary technology to deliver proton therapy radiation with unmatched precision and the utmost care. It’s one of the safest and most effective cancer treatments in the world, which can result in high cure rates, reduced side effects and improved outcomes.

Benefits of Our
Pencil Beam Technology

Compared to standard X-ray radiation and other treatment technologies, California Protons offers patients:

Unmatched Precision

Proton beams can be manipulated to conform to the unique size and shape of the tumor and stop at its edge precisely.

Radiation Dose Variation

Doctors can vary the intensity of the radiation dose at any point within the tumor to optimize treatment.

Treatment for More Tumor Types

Patients with tumors that are larger, more irregularly shaped or found near critical organs or structures can be treated.

Lower Incidence of Secondary Tumors

Reduced radiation to healthy tissues lowers the risk of secondary cancer.

Reduced Side Effects

Diarrhea, nausea, headache and loss of appetite are less likely.

Faster Treatment Times

Our treatment plans can be loaded into the computer and completed in a matter of minutes.
