Delayed Radiation Injury

Radiation therapy is a key component of many cancer treatment strategies; however, like all medical treatments, it carries the risk of unwanted side effects. These side effects can range from acute—such as burns, bleeding, jaw problems, and fibrosis (the buildup of excess fibrous tissue)—to chronic, which may appear months or even years after treatment. Chronic side effects can include long-term damage to tissues or bones. The severity of these effects varies between individuals, depending on their sensitivity to radiation. Unfortunately, no reliable tests currently exist to predict how an individual will respond. The decision to pursue radiation therapy involves weighing risks against benefits while addressing any side effects that arise during or after treatment.

Causes of Chronic Radiation Damage

Many cells in the body have an impressive capacity to repair themselves within weeks of completing radiation therapy. However, some tissues—particularly skin, gastrointestinal tissue, and bone—are more sensitive to radiation damage and may struggle to recover fully. Proper pain management and nutrition can often support the healing process, but complications can still occur. Chronic radiation complications are typically caused by scarring and narrowing of blood vessels in the irradiated area. Over time, as blood vessels become progressively narrowed, the tissues that rely on those vessels for oxygen and nutrients can become damaged or die.

How Hyperbaric Oxygen Therapy (HBOT) Can Help

Hyperbaric Oxygen Therapy (HBOT) has been used for decades to address the effects of chronic radiation damage. A recent review of 11 clinical trials concluded that HBOT can help improve healing in irradiated tissues and may prevent damage to bones.

HBOT works in the following ways:

• Stimulates the creation of new blood vessels (angiogenesis), improving blood supply to affected tissues.
• Enhances tissue oxygenation, providing more oxygen to areas with impaired blood flow.
• Reduces fibrosis, helping to improve tissue flexibility and function.
• Mobilizes stem cells to the damaged area, supporting the growth and repair of healthy tissues.

Areas Treated with HBOT

HBOT can be used to address radiation-induced damage in various tissues and organs, including the:

• Brain
• Muscles
• Face and throat
• Bladder
• Intestines and rectum

Treatment Details

• Each HBOT session typically lasts 90 minutes.
• A full course of treatment usually involves 30 to 40 sessions, depending on individual needs and the extent of tissue damage.
• Over time, HBOT aims to preserve the health and function of tissues and organs affected by radiation.

Health Canada Compliance Notice

While HBOT is recognized for certain approved conditions, its use for addressing radiation-related side effects must be assessed on a case-by-case basis by a qualified healthcare provider. Patients are encouraged to consult with their naturopathic doctor to determine whether HBOT is appropriate as part of their care plan.
