What it is
Hyperbaric oxygen therapy (HBOT) involves breathing oxygen at higher-than-normal air pressure, usually inside a specially built chamber. The aim is to raise the amount of oxygen carried in the blood and delivered to tissues.
Radiation injury, sometimes called radiation tissue injury or late radiation effects, can develop in healthy tissue near an area treated with radiation. It may show up months or years later as skin breakdown, slow-healing wounds, or changes in tissue such as bone or soft tissue. Reduced blood supply in the affected area is one reason these tissues can heal slowly.
HBOT for certain radiation tissue injuries is among the indications the FDA has cleared for hyperbaric oxygen. Not every radiation-related problem qualifies, and use outside cleared indications is a different matter. Only a licensed clinician can say whether it is appropriate for a particular person after an evaluation.
How it’s traditionally been approached
HBOT has traditionally been used as an add-on, or adjunct, to other care rather than a stand-alone answer. In radiation injury, it has often been considered alongside wound care, medication, procedures, or surgery, depending on the situation.
Treatment is typically delivered at a hospital-based or outpatient hyperbaric center. Sessions take place in a chamber under the supervision of trained staff, and the overall course is set by the treating clinician rather than by the patient or a general guideline.
Practices differ between centers and clinicians, and coverage rules vary by payer and diagnosis. Some people are not good candidates because of other health conditions or medications, which is one reason an individual evaluation matters.
How the right wound care specialist may help
The right wound care specialist may help by looking at the wound or affected area, asking about your radiation history, and reviewing your overall health. They may explain the likely cause of the problem, how it is being staged, and whether HBOT is something to consider or whether other approaches make more sense.
A first visit is often a conversation and an exam. You may be asked about past cancer care, other medical conditions, current medications, and symptoms such as pain or drainage. Some specialists coordinate with your oncology, surgical, or primary care team so everyone is working from the same information.
Good questions to bring include: What is causing my wound or tissue problem? Is hyperbaric oxygen cleared for my specific situation? What are the risks and alternatives? How long might healing take? What will insurance cover, and what might I owe? Who will monitor my progress, and what signs should prompt me to call?
The whole-person view
Body, mind, and stress affect each other, and that is especially true after cancer treatment. Living with a slow-healing wound, repeated appointments, and uncertainty can wear on sleep, mood, and energy, and stress can in turn make coping with physical symptoms harder.
Many people find it helpful to support the whole person alongside medical care. Somatic Experiences offers body-based support that some people use to build awareness of tension and stress, and Therapists.plus can connect people with talk therapy for the emotional side of a long recovery. Both can sit alongside, not replace, care from your medical team.

Keep in mind
- Licensed professionals should guide any care involving radiation injury, cancer history, or non-healing wounds; this page does not diagnose or recommend treatment.
- Seek medical care promptly for signs of infection such as spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever, or chills, or for a wound that is rapidly worsening.
- Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, signs of sepsis, or a deep or severely contaminated wound. If you are in emotional crisis, call or text 988.
- HBOT is not right for everyone, results are never guaranteed, and a licensed provider should explain your wound's cause, staging, options, expected healing time, and insurance coverage.

Frequently asked questions
What is hyperbaric oxygen therapy for radiation injury?
Hyperbaric oxygen therapy for radiation injury is the use of pressurized oxygen in a chamber to support tissue affected by earlier radiation treatment. It is an FDA-cleared indication for certain radiation tissue injuries. Whether it fits a given person is a decision for a licensed clinician after an evaluation.
Is hyperbaric oxygen therapy FDA-cleared for radiation injury?
Yes, certain radiation tissue injuries are among the FDA-cleared indications for hyperbaric oxygen. Clearance applies to specific conditions, not every radiation-related symptom. Ask your provider whether your situation is one of them.
What kinds of radiation injury are discussed with HBOT?
Clinicians may consider HBOT for late effects in tissue near a previously radiated area, such as slow-healing wounds or damaged soft tissue or bone. Which problems qualify depends on the details of your case. A specialist can explain how your condition is classified.
What happens during a hyperbaric oxygen session?
You generally rest in a chamber while breathing oxygen under increased pressure, with trained staff monitoring you. You may feel pressure in your ears, similar to changing altitude. Your provider can describe what to expect, how sessions are scheduled, and any risks.
Does insurance cover hyperbaric oxygen therapy for radiation injury?
Coverage varies by payer, diagnosis, and plan rules, and approval is often required in advance. Ask your provider's office and your insurer what is covered and what you might owe. Do not assume coverage before confirming it.
How do I find a wound care specialist for radiation injury?
Start by asking your oncology, surgical, or primary care team for a referral, or look for a licensed wound care or hyperbaric medicine provider through a directory such as WoundKare. Ask about their experience with radiation-related wounds and whether they coordinate with your other doctors.
