Board-certified radiation oncology with over 20 years of experience — now offering breakthrough Low-Dose Radiation Therapy (LDRT) for osteoarthritis joint pain. No surgery. Minimal side effects. Real relief.
Dr. Hai A. Tran is a board-certified radiation oncologist serving the Texarkana, Texas and Arkansas community with compassionate, evidence-based care. A graduate of the University of Wisconsin School of Medicine & Public Health, he completed his residency in Radiation Oncology at the University of California, Irvine — and has been in practice for more than 20 years.
Dr. Tran is one of the few radiation oncologists in the Ark-La-Tex region offering Low-Dose Radiation Therapy (LDRT) for osteoarthritis — a breakthrough, non-surgical option for patients suffering from chronic joint pain who have not found relief through traditional therapies.
"My goal is to bring the most advanced radiation therapies — both for cancer and for pain — directly to Texarkana families so they don't have to travel far from home for world-class care."
From precision cancer treatment to innovative joint pain therapy, our practice offers a full spectrum of radiation-based treatments in a warm, patient-centered environment close to home.

What is Low-Dose Radiation Therapy for joint pain?
LDRT uses very small amounts of radiation — far below doses used for cancer treatment — to reduce the chronic inflammation driving osteoarthritis pain. The therapy has been used in Europe for over 100 years with excellent safety data, and is now gaining widespread recognition in the United States as a powerful, non-invasive alternative.
Unlike steroids, NSAIDs, or opioids, LDRT addresses the underlying inflammatory process rather than masking symptoms. Patients typically receive 6 treatments over 2–3 weeks, each lasting only a few minutes. There's no anesthesia, no needles, and no recovery time.
Clinical studies have shown that approximately 60–80% of patients experience meaningful, lasting pain relief — with some remaining symptom-free for years after a single course of treatment.
If you have been living with joint pain and conventional treatments like physical therapy, cortisone injections, or pain medications haven't provided adequate relief — LDRT may be the answer.
Meet with Dr. Tran to review your history, imaging, and discuss whether LDRT is appropriate for your joint condition.
A brief planning session maps the targeted joint area to ensure precise, low-dose delivery to the inflamed tissue.
Receive 6 painless treatments over 2–3 weeks. Each session lasts only 5–15 minutes. No anesthesia needed.
Pain reduction typically begins within weeks. Dr. Tran monitors your progress and can repeat the series if needed.
LDRT offers a compelling combination of benefits that no other joint pain treatment can match — especially for patients who want relief without surgery or long-term medication dependence.
LDRT is completely non-invasive. There's no cutting, no implants, no general anesthesia, and no hospital stay. Patients walk in and walk out the same day.
A complete treatment course is only 6 sessions over 2–3 weeks. Each session is just minutes long — fitting into even the busiest schedule with no downtime.
The radiation doses used are extremely small — roughly equivalent to a CT scan. Decades of European data confirm LDRT is safe with minimal side effects.
Many patients experience sustained pain relief for 12 months or more — and a second series can be performed if symptoms return over time.
Effective pain control from LDRT may allow patients to reduce or eliminate reliance on NSAIDs, opioids, and corticosteroid injections with their associated risks.
No need to travel to Dallas or Little Rock. Dr. Tran brings this advanced therapy directly to Texarkana — convenient for patients across the Ark-La-Tex region.

Have questions about LDRT or radiation oncology? Here are the ones we hear most often from patients and referring physicians.
I had struggled with knee pain for years and was told I needed a knee replacement. A friend mentioned LDRT and I decided to try it first. Six weeks after finishing treatment, the pain is dramatically better. I'm back to gardening and walking my dog every day. I could not be more grateful.
Dr. Tran treated my prostate cancer last year. From the very first appointment, he explained everything clearly, answered all my questions, and made me feel like a person — not just a patient. I am grateful every day for his expertise and his kindness.
My shoulder had been killing me for two years. I had injections, physical therapy — nothing lasted. My rheumatologist referred me to Dr. Tran for LDRT. Two months later, I have my life back. The staff here is wonderful and the whole experience was easy and painless.
