There are two types of lymphedema: primary and secondary. Primary lymphedema,
also known as congenital lymphedema, can be present at birth or develop at
the onset of puberty or in adulthood, all from a variety of causes. This is
a less common type of lymphedema. Secondary lymphedema, also known as acquired
lymphedema, is the more common type. Most often, secondary lymphedema occurs
following surgery, especially after the removal of one or more lymph nodes.
Among the surgeries that require the removal of lymph nodes are those for breast,
gynecological, head and neck, prostate, testicular, bladder and colon cancer,
and melanoma. Lymphedema can develop immediately after surgery or months to
years following cancer treatment. Secondary lymphedema can also develop following
scarring from infection or radiation therapy, or it may result from traumatic
injury to a part of the lymphatic system.
