Radiation InjuryTreatment & HBOTSan Antonio

Radiation can continue affecting healthy tissue months or even years after cancer treatment, leading to wounds, bleeding, pain, bone damage, or soft tissue breakdown. Our physician-led team evaluates delayed radiation injuries and provides HBOT when medically appropriate to help increase oxygen delivery, support new blood vessel growth, and promote healing in damaged tissue.

Radiation-Related Conditions We Treat

Radiation Can Injure Any Tissue It Touches

Delayed radiation injury can affect any tissue that received radiation. Our team specializes in the full spectrum of radiation-related conditions — from bladder and bowel to bone and skin.

Bladder

Radiation Cystitis

Radiation to the pelvis for bladder, prostate, cervical, or rectal cancers can damage the bladder lining, causing chronic inflammation, bleeding (hematuria), pain, and urinary urgency. Hemorrhagic radiation cystitis — persistent bladder bleeding — is one of the most challenging late effects of pelvic radiation. HBOT is a medically recognized indication for this condition, stimulating new vessel growth in the hypoxic bladder wall to reduce bleeding and restore normal tissue function.

Common Symptoms

Blood in urine (hematuria)
Frequent or urgent urination
Pelvic pain or pressure
Urinary incontinence
Rectum

Radiation Proctitis

Radiation to the pelvis can injure the rectal mucosa, causing chronic radiation proctitis — inflammation, ulceration, bleeding, and stricture of the rectum and sigmoid colon. Symptoms often appear months to years after treatment for prostate, cervical, or rectal cancers. HBOT promotes angiogenesis in the damaged rectal wall, reduces chronic inflammation, and heals mucosal ulcerations that do not respond to standard gastroenterological management.

Common Symptoms

Rectal bleeding or discharge
Urgency or tenesmus
Diarrhea or mucus in stool
Rectal pain or stricture
Prostate / Pelvis

Radiation Prostatitis / Pelvic Tissue Injury

Men treated with radiation for prostate cancer frequently develop late tissue effects in the surrounding pelvic structures — including the prostate, urethra, bladder, and rectum. These late radiation effects cause chronic pain, urinary and bowel dysfunction, and non-healing tissue breakdown. HBOT combined with targeted wound care addresses the hypoxic tissue environment driving these symptoms, improving quality of life when conventional urology management has plateaued.

Common Symptoms

Urinary frequency, urgency, or retention
Pelvic pain or discomfort
Rectal symptoms (bleeding, urgency)
Erectile dysfunction from vascular damage
Soft Tissue

Soft Tissue Radionecrosis

Soft tissue radionecrosis (STRN) occurs when radiation permanently damages blood vessels supplying skin and underlying soft tissue, leading to chronic non-healing wounds, ulceration, and tissue breakdown — often in the chest wall, neck, groin, or extremity. Unlike standard wounds, these injuries cannot heal without restoring oxygen delivery. HBOT and advanced wound care — including biologic skin substitutes — are the cornerstone of treatment.

Common Symptoms

Non-healing wound in a previously irradiated area
Skin that appears pale, fibrotic, or ulcerated
Pain, tenderness, or chronic drainage
Wound enlargement despite standard dressing care
Bone

Osteoradionecrosis (ORN)

Osteoradionecrosis is the death of bone tissue in a previously irradiated field — most commonly the jaw (mandible) following head and neck radiation, but also affecting the hip, sternum, or other bones. ORN often develops after dental extractions, trauma, or surgery in the irradiated field. HBOT is the evidence-based standard of care: 20 pre-operative and 10 post-operative sessions before dental work dramatically reduce ORN risk, and established ORN responds to extended HBOT protocols.

Common Symptoms

Exposed bone in the mouth or wound
Pain and swelling in the jaw or affected bone
Non-healing socket after dental extraction
Difficulty eating, speaking, or opening the mouth
Skin

Radiation-Induced Skin Wounds

Acute radiation dermatitis and chronic radiation skin injury range from superficial erythema and desquamation during treatment to chronic fibrosis, telangiectasia, and full-thickness ulceration years later. The skin in irradiated fields lacks the vascular reserve to heal from any new injury. Our team applies advanced wound dressings, biologic products, and HBOT to restore healing capacity in chronically damaged irradiated skin.

Common Symptoms

Redness, dryness, or peeling in the radiation field
Fibrosis — skin that feels tight or leathery
Open wounds or ulcers on previously treated skin
Chronic pain, itching, or sensitivity in the area

The Common Thread

HBOT Is the Cornerstone Treatment for Delayed Radiation Injury

Regardless of where the radiation damage occurred, the core problem is the same: hypoxic, hypovascular tissue that cannot heal. HBOT addresses this directly — and is a medically recognized indication for delayed radiation injury.

Why It Matters

Delayed Radiation Injury Is Unique.It Requires Specialist Care.

Radiation permanently damages the small blood vessels that supply oxygen to tissue. The result is a hypoxic, hypovascular, hypocellular environment — tissue that is chronically starved of the oxygen and nutrients needed for healing, immune response, and surgical recovery.

Standard wound care alone cannot overcome this. Without restoring oxygen delivery to irradiated tissue — through HBOT — wounds in radiation fields will not heal, infections will persist, and reconstructive procedures will fail. Early specialist intervention dramatically changes long-term outcomes.

Warning Signs

Don't wait — seek specialist care

Skin breakdown, ulceration, or open wounds in a previously irradiated area
Chronic pain, burning, or numbness in tissues that received radiation
Fibrosis — skin or tissue that feels hard, tight, or leathery after radiation
Wounds in an irradiated field that have not healed after 3–4 weeks
Osteonecrosis — exposed or infected bone in a radiated area (especially jaw)
Bleeding, fistula, or non-healing tissue breakdown from delayed radiation injury
Your Healing Plan

Your Personalized Delayed Radiation Injury Healing Plan

01

Delayed Radiation Injury Assessment

We evaluate the extent, depth, and timeline of your delayed radiation injury — identifying tissue perfusion deficits, assessing fibrosis, and reviewing your cancer treatment history to build the most appropriate healing plan.

02

Hyperbaric Oxygen Therapy (HBOT)

HBOT is a recognized treatment option for delayed radiation injury, including soft tissue radionecrosis and osteoradionecrosis, when medically appropriate. Breathing 100% oxygen at 2.0–2.4 ATA stimulates new blood vessel growth (angiogenesis) in hypoxic irradiated tissue — reversing the core defect that prevents healing and enabling wound closure and tissue recovery.

03

Advanced Wound Debridement

Radiation-damaged tissue has fragile, compromised vascularity. Our physicians use gentle, targeted debridement methods — enzymatic and autolytic — to remove non-viable tissue without traumatizing the surrounding irradiated wound bed.

04

Infection Management

Radiation-compromised tissue has a severely impaired immune response. We culture wounds early, prescribe appropriate antibiotics, and monitor closely for signs of osteomyelitis, deep tissue infection, or systemic spread.

05

Advanced Wound Dressings

We select moisture-balanced dressings specifically chosen for fragile, hypoxic tissue — antimicrobial silver, hydrogels, and non-adherent foams — that protect the wound bed and support healing without disrupting delicate irradiated skin.

06

Biologic & Cellular Tissue Products

For radiation wounds that stall, advanced biologic skin substitutes and amnion/chorion membrane allografts introduce growth factors and scaffolding that irradiated tissue can no longer produce on its own — jumpstarting the healing cascade.

07

Oncology & Surgical Team Collaboration

We work directly with your radiation oncologist, surgeon, and primary care provider to ensure your wound care plan fits within your overall cancer care — coordinating pre- and post-surgical HBOT, reconstructive planning, and long-term tissue monitoring.

Delayed Radiation Injury Treatment with Hyperbaric Oxygen Therapy (HBOT) in San Antonio

Hill Country Wound Care and Hyperbarics is a leading provider of treatment for delayed radiation injuries in San Antonio, Texas. Our board-certified physicians in Hyperbaric Medicine specialize in using Hyperbaric Oxygen Therapy (HBOT) to treat a range of late radiation effects, including osteoradionecrosis (ORN), soft tissue radionecrosis, radiation cystitis, and radiation proctitis. With three clinics equipped with hyperbaric chambers, we offer accessible, outpatient care for cancer survivors suffering from the long-term consequences of radiation therapy.

Understanding Delayed Radiation Injury

Radiation therapy, while effective at killing cancer cells, also damages surrounding healthy tissue by destroying small blood vessels. This creates a state of chronic hypoxia (low oxygen), preventing the tissue from healing, fighting infection, or recovering from subsequent surgery or trauma. These effects can manifest months, years, or even decades after treatment is complete. HBOT is the primary medical treatment that directly counteracts this process by stimulating angiogenesis (the growth of new blood vessels) in irradiated tissue.

Conditions Treated with HBOT

Our program treats all forms of delayed radiation injury, including: Osteoradionecrosis (ORN), particularly of the jaw (mandible) after head and neck cancer treatment; Soft Tissue Radionecrosis, causing non-healing wounds in the chest wall, pelvis, or extremities; Radiation Cystitis, leading to bladder bleeding (hematuria); and Radiation Proctitis, causing rectal bleeding and pain. HBOT is a UHMS and Medicare-approved indication for these conditions.

The HBOT Treatment Protocol

Patients undergo a series of treatments in a monoplace hyperbaric chamber, breathing 100% oxygen at 2.0 to 2.4 times normal atmospheric pressure for 90-120 minutes per session. A typical course for delayed radiation injury involves 30-40 sessions. This process supersaturates the blood plasma with oxygen, forcing it into the hypoxic irradiated tissues to stimulate new blood vessel growth, reduce inflammation, and restore healing capacity.
