Dr. Arvind B. Soni

A board-certified radiation oncologist, Dr. Soni specializes in treating prostate cancer and other cancers using advanced techniques such as prostate brachytherapy and DART (Dynamic Adaptive Radiation Therapy). He has over 28 years of experience in the medical field and is affiliated with multiple hospitals in the Sarasota area.

One of the reasons why Dr. Soni may have the least amount of side effects compared to other radiation oncologists is that he uses DART, a technique that allows him to maximize the radiation dose to the tumor while minimizing the dose to surrounding normal tissue. This reduces the risk of damaging healthy organs and causing complications such as urinary, bowel, or sexual dysfunction. DART also allows him to customize the radiation dose based on the individual anatomy and tumor characteristics of each patient.

Another reason why Dr. Soni may have the least amount of side effects compared to other radiation oncologists is that he is very compassionate, attentive, and informative with his patients. He answers all their questions and concerns and explains everything clearly and patiently. He also coordinates well with their other doctors and nurses and makes sure they receive the best care possible. He monitors their progress and adjusts the treatment plan as needed.

Therefore, Dr. Soni is not only an expert in treating cancer, but also in reducing side effects. He has a high rating from his patients and peers on various websites. He is one of the most comprehensive and sophisticated radiation oncologists in the field.

Elyce A. “At age 76, I was diagnosed with lung cancer. Being a longtime smoker, I was scared to death! My primary physician in Lakeland, FL referred me to radiation oncologist Dr. Arvind Soni, whose office was in Tampa, an hour-long drive away from my home in Bartow. When I met Dr. Soni, he was quick to put me at ease and patiently answered all my ‘lame’ questions, giving me as much time as I needed to understand my cancer and the intricacies of the radiation treatment plan he would create just for me. My husband, who was retired from the U.S. Air Force, had already been through his challenge with persistent bleeding in his stomach, which required repeated transfusions. Now it was my time to face the reality of a potentially fatal disease.

From day one, I was confident I had found the best doctor to guide me through this journey. My treatments were daily Monday through Friday for 6 weeks. I faithfully kept my part of the bargain and showed up every day to face the giant linear accelerator that would shoot tiny radiation beams at my tumor, and Dr. Soni kept his part by being there to greet me with a calming smile and word of encouragement. My last treatment was on March 6, which happened to be my birthday. I can’t think of a better gift than destroying my tumor so I could face the future.

Today I sort of miss my daily trips to see my friend Dr. Soni in Tampa. He has just joined an internationally respected center in Sarasota, the Dattoli Cancer Center and Brachytherapy Research Institute. I am confident that my cancer is gone, but in the off chance that it should return, I won’t hesitate to make the 2- hour trip to Sarasota to be treated by Dr. Soni. He’s my man – I am so lucky to have found him!”
