Radiotherapy Side Effects and How to Manage Them

Radiotherapy is a common treatment for cancer, but it can also cause a range of side effects. In this blog post, we’ll discuss some of the most common side effects of radiotherapy and provide tips on how to manage them.

Skin Changes

Radiotherapy can cause skin changes, such as redness, dryness, itching, and peeling. In some cases, the skin may also become more sensitive to the sun.

How to Avoid Skin Problems

  • Protect your skin from the sun by wearing sunscreen, sunglasses, and a hat.
  • Avoid using harsh soaps and detergents.
  • Moisturize your skin regularly.
  • Avoid scratching or picking at your skin.

Hair Loss

Radiotherapy can also cause hair loss. This is usually temporary, and hair will typically grow back after treatment is completed.

Mouth Problems

Radiotherapy can cause mouth problems, such as dryness, soreness, and difficulty swallowing. In some cases, it can also lead to tooth decay.

How to Manage Mouth Problems

  • Drink plenty of fluids to stay hydrated.
  • Eat soft, easy-to-swallow foods.
  • Avoid spicy, acidic, or salty foods.
  • Brush your teeth and floss regularly.
  • See your dentist regularly for checkups.

Stomach Problems

Radiotherapy can cause stomach problems, such as nausea, vomiting, and diarrhea. In some cases, it can also lead to weight loss.

Bladder Problems

Radiotherapy can cause bladder problems, such as increased urination, urgency, and incontinence. In some cases, it can also lead to urinary tract infections.

Fertility Changes

Radiotherapy can affect fertility in both men and women. In men, it can lead to a decrease in sperm production. In women, it can lead to early menopause or infertility.

Changes in Sex Life

Radiotherapy can also affect a person’s sex life. In men, it can lead to erectile dysfunction. In women, it can lead to vaginal dryness and pain during sex.
