Radiation Tissue Damage and HBOT: Healing Wounds After Cancer Treatment

Cancer radiation therapy saves lives, but it can leave lasting damage to the tissues in the treatment field. Months or even years after radiation is completed, patients may develop wounds that will not heal, tissue breakdown, bone death, or chronic pain in the irradiated area. At Elite Wound Care Center in Palm Harbor, we use hyperbaric oxygen therapy to help cancer survivors heal from the late effects of radiation.

How Radiation Damages Tissue

Radiation therapy works by damaging the DNA of rapidly dividing cancer cells. Unfortunately, it also damages normal cells in the treatment area, particularly the cells that line blood vessels. Over time, this vascular damage leads to a progressive loss of blood supply in the irradiated tissue. The process, called obliterative endarteritis, causes the small blood vessels to narrow and close off, creating tissue that is hypoxic, hypovascular, and hypocellular — meaning it has too little oxygen, too few blood vessels, and too few cells.

This damaged tissue may function adequately under normal conditions but lacks the reserve capacity to heal when injured. A surgical procedure in a previously irradiated area, a dental extraction from an irradiated jaw, or even minor trauma can create a wound that the devitalized tissue cannot repair.

Common Radiation Injuries We Treat

The most common radiation-related conditions we see at Elite Wound Care Center include osteoradionecrosis, which is death of bone tissue in the jaw or other irradiated bones; soft tissue radionecrosis, which involves breakdown of skin, muscle, or other soft tissue in the radiation field; radiation cystitis, which causes bleeding and tissue damage in the bladder after pelvic radiation; radiation proctitis, involving damage to the rectum after treatment for prostate, cervical, or rectal cancer; and non-healing surgical wounds in previously irradiated tissue.

Why HBOT Is Uniquely Effective for Radiation Injuries

HBOT is one of the few treatments that directly addresses the underlying cause of radiation tissue damage. While standard wound care treats the surface of the wound, HBOT works at the vascular level to rebuild the blood supply that radiation destroyed.

Over a course of 40 to 60 treatments, HBOT stimulates angiogenesis — the growth of new blood vessels — in the irradiated tissue. These new capillaries gradually restore oxygen delivery to the affected area, transforming tissue that was incapable of healing into tissue with a functional blood supply. Research has shown that the new blood vessels created through HBOT are durable, with studies demonstrating sustained vascularity years after treatment.

Planning Ahead: Pre-Treatment HBOT

If you need surgery or dental work in a previously irradiated area, HBOT before the procedure can significantly reduce the risk of wound complications. A series of 20 pre-operative HBOT sessions prepares the tissue by improving blood supply before the surgical trauma occurs, followed by 10 post-operative sessions to support healing.
