Cutaneous and mucosal reactions

Chemotherapy and radiation can produce skin reactions of varying intensity, such as changes in the colour, texture or integrity of the skin and mucous membranes (e.g. inside the mouth, nose, etc.).

The most common side effects include dry skin, changes in colour, increased sensitivity to sunlight, ulcers and acne reactions.
