Radiation fibrosis occurs when the body’s tissue reacts to the high doses of radiation by becoming scarred, stiff, and less functional. This condition can affect head and neck cancer survivors, causing tissue stiffness, pain, and functional limitations long after treatment.
What Is Radiation Fibrosis?
Radiation fibrosis occurs when healthy tissue is damaged during radiation therapy, triggering inflammation and the overproduction of collagen. Over time, this leads to scar formation, poor circulation, and tissue rigidity.
These effects can worsen without treatment, but modern therapies offer solutions to restore tissue flexibility and function.
Patients may describe their symptoms as:
- “Radiation fibrosis” or “fibrosis after cancer treatment”
- “Difficulty opening my mouth” (trismus)
- “Problems swallowing” (dysphagia)
- “Tightness or pain in the neck”
