Radiation & Chemotherapy Side Effects

Radiation therapy (or radiotherapy) is the medical use of ionizing radiation as part of cancer treatment to control malignant cells. It is used for curative, adjuvant, and palliative therapy, and is often combined with surgery, chemotherapy, and hormone therapy to fight the cancer.

Medium and long-term effects of radiotherapy include dryness of the tear and salivary glands, hair loss, and fibrosis. Fibrosis is the tightening of tissues over time from a diffuse scarring process. Fibrosis of the face, jaw and neck can lead to trismus or the limiting of mouth opening. Jaw motion rehab devices, like the OraStretch® press, is commonly used to stretch the jaw to prevent radiation induced trismus and to overcome trismus.
