How can I avoid putting pressure on my arm to prevent breast lymphedema?

Breast lymphedema is a problem that may occur after surgery and treatment of breast cancer. It is the swelling of the arm, armpit, breast, or chest wall, on the side where the breast surgery was done. Too much pressure on the arm may lessen the flow of the lymphatic fluid through the arm. To avoid this, do the following:

• Have blood pressure checked on the unaffected arm.
• Avoid wearing tight clothing or sleeves with tight elastic bands on the arm.
• Avoid wearing tight jewelry on the arm, such as watches or rings. Wear these things on the unaffected side.
• Carry your purse on the unaffected side.
