Palpable lymph nodes

Abstract

Lymph nodes can increase in size in a number of conditions. Infections, cancer and many immune diseases can affect lymph cells and cause an enlargement of lymph nodes. Enlarged lymph nodes are often the first sign of lymphoma, a cancer of lymph cells. But all enlarged nodes are not lymphoma. (See the article Are Enlarged Lymph Nodes Always a Lymphoma?). Any enlarged node should be brought to the notice of a physician and investigated for the correct diagnosis.
