Prostate Cancer

Prostate cancer strikes 313,780 men in 2025. One in eight men are at risk for prostate cancer in their lives, but precision care transforms outcomes. Ackerman Cancer Center in Northeast Florida provides advanced prostate cancer treatment with unmatched accuracy to protect your quality of life.

How we treat Prostate Cancer

Ackerman Cancer Center provides external beam radiation therapy using high‑energy X‑rays on advanced linear accelerators to safely and effectively treat cancers from head to toe. Using 3D conformal radiation therapy (3D-CRT), Intensity-Modulated Radiation Therapy (IMRT), and Volumetric Modulated Arc Therapy (VMAT), treatment plans are customized to each patient’s unique anatomy to help target the tumor while protecting healthy tissue. Most patients receive painless daily treatments over several weeks. Each visit typically lasts less than 20 minutes, including positioning on the treatment table, cone‑beam CT imaging to align to internal anatomy, and focused treatment to the target area.

Ackerman Cancer Center offers proton therapy with a Mevion S250 proton system for eligible patients. Proton beam therapy can treat both shallow and deep tumors while helping to spare nearby organs. This is possible because the proton beam can stop near the tumor instead of passing through the body. This advanced treatment is not available at most radiation centers, but the Ackerman team has more than 10 years of proton experience, celebrating its 3,500th proton patient in 2026.

Ackerman Cancer Center provides Stereotactic Body Radiation Therapy (SBRT) for many areas of the body, including the lung, liver, kidneys, and spine, as well as other carefully selected sites. SBRT typically involves five or fewer treatments, each delivering a very high dose of radiation to a small, precisely defined target. With advanced imaging, specialized treatment planning, and state‑of‑the‑art linear accelerators, SBRT allows patients to complete treatment in fewer visits while maintaining accuracy and safety. Frequently, patients receiving SBRT experience very few side effects. 

Ackerman Cancer Center provides High Dose Rate (HDR) brachytherapy for many skin and gynecologic cancers, as well as selected breast cancers. HDR brachytherapy uses a tiny radioactive source that is temporarily placed inside or next to the treatment area to deliver radiation right at and even touching the cancerous target. This technique gives a highly focused dose to a small region and avoids the entrance and exit dose associated with external beam radiation, thereby aiding in the protection of nearby healthy tissue.  

Ackerman Cancer Center offers radiopharmaceutical therapy for certain thyroid and prostate cancers. In this treatment, patients receive a radioactive drug that travels through the bloodstream, seeks out specific cancer cells, and delivers radiation directly to those cells from within the body. This targeted approach allows a high dose of radiation to reach the disease while limiting exposure to other tissues.

Personalized Prostate Cancer Care at Ackerman Cancer Center

Our specialists focus on delivering powerful prostate tumor control while safeguarding
vital surrounding tissues like the bladder, rectum, and bowel to minimize side effects and speed recovery. We also offer BioProtect spacers, a minimally invasive option that creates space between the prostate and rectum for enhanced rectal protection during
radiation therapy. We prioritize your long-term wellness through prostate cancer care in
Northeast Florida that reduces risks of recurrence and complications. Each treatment plan is designed to aggressively treat cancer while protecting the quality of life that matters most to you.
