Cellulitis

Cellulitis is a skin infection.

Trapped fluids are an ideal place for germs to flourish, so it’s common in lymphedema.

It also can occur four to six weeks after radiation, and then gradually go away.

However, the most common punch in develops two years or more after treatment and tends to be permanent.

The arm swelling is usually evident, but it can be subtle.

Lymphedema is sparked by swelling that follows damage to the lymph system during breast cancer treatment.

This damage to lymph nodes and vessels limits the ability to drain lymph properly from the arm and chest.

Symptoms tend to cause pain and discomfort.

Lymphedema can be treated with compression sleeves and other interventions.

Rarely, a serious complication such as sepsis can prove life-threatening though lymphedema itself is not.
