Enlarged Lymph Nodes can occur in the groin, either singularly or in multiples. These will similarly manifest as lumps in the groin, though lymph nodes tend to be firmer and also rubbery in texture.
The common causes of enlarged Lymph Nodes include blood (haematological) cancers such as leukaemia or lymphoma, infection of the lower limb or a reactive lymph node. Reactive lymph nodes enlarge in response to an infection but fail to shrink in size subsequently when the infection is cleared.
Any enlarged Lymph Node warrants surgery to have the enlarged lymph node removed and examined in the lab under a microscope. No enlarged lymph node should be ignored or left alone.
