Three Lifesaving Partners in One Location
The most significant contribution to cancer care in decades, Southwest Florida Proton is making history as the first proton treatment center on the Gulf Coast of Florida. This historic development represents a lifesaving resource for cancer patients across the globe seeking world-class treatment options.
Led by three powerful lifesaving partners at the forefront of cancer care, the center is currently providing consultations for proton therapy and scheduling appointments for both traditional radiation therapy and Diagnostic Outpatient Imaging.
The Precision & Power of Proton Therapy
Southwest Florida Proton is one of only 46 proton therapy providers located throughout the U.S. Delivering highly concentrated radiation to the tumor via a proton beam, this advanced technology also targets cancer tumors more precisely than ever before. Proton therapy pinpoints the target closely to avoid the impact on healthy tissues around the treatment site, including vital organs such as the heart or brain. As a result, the treatment offers the lowest potential short- and long-term side effects possible.
Oncologists may recommend proton therapy based on the age of the patient, the location of the tumor, or the aggressiveness of the cancer. For example, proton therapy is often beneficial to patients with the following conditions:
