3. Enlarged Lymph Nodes

Painless swelling of the lymph nodes is a frequent sign of CLL. Lymph nodes may enlarge in the neck, under the arms, or in the groin.

Lymph nodes are part of the immune system and normally help filter out infections. In CLL, abnormal lymphocytes can accumulate in these nodes, causing them to swell even in the absence of infection. Enlargement that persists or continues to grow should be medically assessed.
