Enlarged lymph nodes are a common symptom of a variety of medical conditions, including infection, inflammation, and cancer. Checking for enlarged lymph nodes is an important part of a physical examination, as it can help to identify potential health problems. Lymph nodes are small, bean-shaped structures that are located throughout the body. They are part of the lymphatic system, which helps to fight infection and disease. When lymph nodes become enlarged, it can be a sign that the body is fighting an infection or that there is another underlying medical condition.
There are several ways to check for enlarged lymph nodes. One way is to feel for them under the skin. Lymph nodes are typically located in the neck, armpits, and groin. They can be felt as small, round or oval lumps. If you feel a lump that is larger than a pea, it is important to see a doctor to have it checked out.
