Why patients choose TBRO
Tampa Bay Radiation Oncology is a stand-alone radiation oncology practice with three offices in Tampa and Brandon. Decades of experience, no hospital campus to navigate. The only CyberKnife® provider in Tampa Bay.
Three stand-alone offices.
We're not a department inside a hospital system. Patients park out front, check in immediately, and are typically in and out in under 30 minutes. Across the dozens of appointments most radiation regimens require, that adds up to hours of life given back to you and your family.
Decades of experience, all under one roof.
Our physicians collectively bring more than 186 years of radiation oncology experience. Dr. Jack Steel alone has performed over 4,000 prostate seed implant procedures. Every modality we offer is delivered by a small, consistent care team that gets to know you across the course of treatment.
The technologies that matter, without the trip.
CyberKnife® radiosurgery (we're the only Tampa Bay provider), IMRT, IGRT, brachytherapy, MammoSite for breast cancer, and surface brachytherapy for skin cancer -- all available at one of our three Tampa Bay offices.

Initial consultations are typically available within 24 to 48 hours of your call.




Our Services
We take pride in our work and the community we perform it in. We offer the full range of modern radiation oncology.

High-Dose Rate (HDR) Radiation Therapy
HDR brachytherapy delivers a concentrated dose of radiation in 10 to 20 minutes -- and unlike traditional seed implants, the radioactive source does not stay in the body.

Image-Guided Radiation Therapy (IGRT)
Image-Guided Radiation Therapy uses real-time imaging at every session to confirm the radiation dose is going exactly where it should.

Intensity-Modulated Radiation Therapy (IMRT)
Intensity-Modulated Radiation Therapy shapes the radiation dose around your tumor in three dimensions, sparing more of the healthy tissue around it.

Leipzig & Valencia Applicators
HDR surface applicators for basal and squamous skin cancers -- no surgery, no scar, treatment complete in about two weeks.

MammoSite Breast Cancer Treatment
Five-day balloon-catheter breast brachytherapy after lumpectomy -- versus seven weeks of daily traditional radiation. No hospitalization.

Prostate Seed Implants
A focused prostate cancer treatment delivered in a single outpatient procedure -- with a fraction of the appointments external beam radiation requires.

Brachytherapy
Internal radiation therapy that places a radioactive source directly inside or next to the tumor -- high local dose, low collateral exposure.

Contura by SenoRx
Multi-lumen breast brachytherapy for women whose lumpectomy cavity isn't a fit for the standard MammoSite balloon.

CyberKnife Radiosurgery
Robotic radiosurgery -- non-invasive, painless, and usually completed in one to five outpatient sessions. The only CyberKnife provider in Tampa Bay.
Cancers and conditions we treat
From prostate cancer and breast cancer to lung, brain, skin, gynecologic, and gastrointestinal cancers -- plus non-cancer conditions like acoustic neuroma and trigeminal neuralgia.
Urologic & Pelvic
Thoracic & Breast
Neurological & Brain
Skin & Gastrointestinal

Patient Stories & Reviews
Reviews and stories from former patients and families treated at our Tampa and Brandon offices.
"This office is amazing! I'm so happy my grandfather has the chance to go get his treatment in this office. Nurse Eileen has been a blessing for us. She is the best nurse ever and is so helpful. She answers all your question and has patience to answer everything. I live in New York and she has made this process very easy for me. If you go to this doctors office please make sure to talk to Nurse Eileen! I promise you that she will be able to answer any question you have if the doctor is not able to be reached. Thank you again for everything you do!"

We start with an initial consultation, either from a reference from your primary care physician or by you calling our team to schedule a second opinion. At that appointment, we'll review any information we have with you and talk about what your next options are. Once you and your physician jointly decide on a path forward, we'll walk you through each of the next steps.
Our team is here 8am–6pm, Monday through Friday. No referral is required for a consultation or second opinion, and initial consultations are typically available within 24 to 48 hours of your call.
