Understanding Lymphadenopathy
Lymphadenopathy is the medical term for swollen lymph nodes and can be classified as localized or generalized. Localized lymphadenopathy affects just one area like the neck or armpit, while generalized lymphadenopathy involves multiple areas. Normal lymph nodes are typically less than 1 cm in diameter, but they can appear larger in adolescence.
Common Causes of Swollen Lymph Nodes
There are numerous causes for swollen lymph nodes, ranging from infections to cancers. Infections such as Epstein-Barr virus or tuberculosis can cause lymph nodes to swell. Some medications can also lead to lymphadenopathy as a side effect. The location of the swollen nodes can often help pinpoint the underlying cause.
When to Worry About Swollen Lymph Nodes
While swollen lymph nodes often indicate a minor issue, they can sometimes signal something more serious like cancer. If nodes are hard, fixed, or rapidly enlarging, or if they are accompanied by symptoms like fever, night sweats, or weight loss, it may be time to consult a healthcare provider. Older patients and smokers should pay particular attention to these signs.
