NEW YORK, June 6, 2018 /PRNewswire-PRWeb/ -- The American Cancer Society estimates that more than 268,000 new cases of
The lymphatic system is part of the body's immune system. It circulates lymphatic fluid throughout the body, a thin, colorless fluid that collects bacteria and waste products that are ultimately flushed out of the body. Surgical treatment of breast cancer often involves removing several lymph nodes from under the arm on the same side as the affected breast. The lymph nodes are examined under a microscope to look for cancer cells that might have drained from the breast into the lymph nodes. Radiation therapy can damage the delicate lymphatic vessels or even the lymph nodes themselves. Over time, this damage to the lymphatic system disrupts the flow of lymphatic fluid, which can then build up and cause the arm to swell.
Anyone who has had lymph node surgery or radiation therapy is at risk for developing lymphedema. Risk is higher when a larger area of the chest and underarm are treated with radiation and when a larger number of lymph nodes are removed. Axillary lymph node dissection, which removes many lymph nodes, conveys a higher risk of lymphedema than the less invasive sentinel lymph node biopsy, which removes fewer lymph nodes. Women who are overweight or obese are more likely to develop lymphedema.
"Some risk factors, such as the type of cancer treatment required, are not under the patient's control," says Dr. Chen. "That said, we can provide guidelines for postoperative care that can reduce risk, and we can also identify early symptoms of trouble that can make lymphedema more responsive to treatment."
"The initial indications of lymphedema can be hard to detect," says Dr. Chen. "It's important to be alert to subtle changes in feeling in the hand and arm even without visible swelling – tingling or numbness that comes and goes; rash, warmth or itching; or rings and bracelets that feel tight. Don't delay seeing the doctor. As time goes on, it is more likely that the lymph will build up in the tissues and that lymphedema will become a persistent and damaging condition."
Treatment of lymphedema may involve a combination of options including compression sleeves, specific exercises, and massage therapy that helps guide the lymphatic fluid out of the arm. Treatment depends on the severity of the condition. Mild lymphedema may flare up occasionally with minor swelling and respond well to periodic treatment. Late-stage lymphedema may be more severe and persistent and require ongoing treatment. "We have many options for treating lymphedema at every stage," Dr. Chen concludes. "Women who are at risk must continue to be vigilant in protecting their hands and arms, pay attention to even the smallest changes, and work closely with their medical teams to minimize the damaging effects of lymphedema."
