What are the common side effects of radiation therapy for skin cancer?

 

 

Radiation therapy for skin cancer, although effective in treating cancer, can cause a number of side effects, especially to the treated area. These side effects generally fall into two categories: early and late.

Early side effects:

•        Skin irritation:

This is the most common side effect, often manifesting as redness, itching, dryness, scaling, peeling, sunburn-like appearance, swelling and tenderness. Severity may vary depending on dose and area treated.

•        Hair loss:

If the treated area includes hairy skin, temporary or permanent hair loss may occur.

•        Fatigue:

Feeling tired and lacking energy is a common side effect, especially during treatment.

•        Skin darkening:

The treated area may become darker than usual after treatment.

•        Infection:

Sensitive skin in the treated area is more susceptible to infection, requiring careful hygiene and monitoring.

Late side effects:

•        Telangiectasia:

This is the appearance of visible, dilated blood vessels on the treated skin.

•        Fibrosis:

Scarring and thickening of the treated skin may occur, especially with higher doses of radiation.

•        Muscle and bone changes:

In rare cases, long-term muscle and bone damage may occur.

Additionally:

•        Radiation recall:

This is a rare but serious reaction that occurs when certain medications, such as certain types of chemotherapy, are given after or during radiation therapy. It causes an intense sunburn-like rash on the treated area.

•        Secondary cancers:

Although rare, there is a slight risk of developing new cancers in the long term, especially with high doses of radiation and treatment of large areas.

Remember:

•        The severity and specific side effects will vary depending on several factors, including the type and size of the cancer being treated, the radiation dose and technique used, individual sensitivity and overall health.

•        Before starting treatment, your doctor will discuss possible side effects and their treatment strategies with you.

•        It is important that you tell your doctor immediately about any skin changes, pain or other concerns so that a proper examination and treatment can be carried out.
