Exceptional Cancer Care in Southwest Florida

A beacon of hope for cancer patients, Southwest Florida Proton will offer exceptional cancer care with uniquely powerful technology. The first proton therapy center on Florida’s Gulf Coast, Southwest Florida Proton will provide advanced cancer treatment by world-class radiation oncologists, harnessing the ability of protons to deliver maximal radiation dose to tumors, while minimizing the short- and long-term side effects of radiation treatment. Now under development, Southwest Florida Proton is scheduled to offer its powerful services in 2024.

Serving patients from Sarasota, Charlotte, Lee, and Collier Counties.

Proton Therapy Minimizes Side Effects

Southwest Florida Proton will specialize in proton therapy, an innovative cancer treatment that reduces the short- and long-term side effects of traditional radiation therapy. Protons have the enhanced ability to minimize radiation dose to critical organs while delivering an effective dose to the target. By maximally sparing normal tissue exposure, this type of therapy minimizes the short-term and long-term side effects of cancer treatment. Studies have indicated that proton therapy reduces long-term side effects in pediatric cancer patients and those who have previously undergone radiation treatments. Proton therapy is also beneficial for cancers of the brain and spine, breast, esophagus, head and neck, liver, lung, eye, pancreas, and prostate, as well as lymphomas and soft tissue sarcomas.
