Doing a quick self-exam is a quick, easy way to check for swollen lymph nodes and other lumps or bumps that could cause concern. These glands that are commonly found in the neck, armpit, groin, and back ear are an important part of the immune system that helps your body ward off infection and disease, so they can also serve as a warning sign for many diseases and conditions. In fact, by simply checking the lymph nodes in your neck, you can tell if you may be at risk for parasites and cancer.
Your lymph nodes are small, kidney-shaped glands that transport nutrients, waste, and fluids from the bloodstream and body tissues. Typically, lymph nodes are not uncomfortable or painful, and you’ll likely not even know they are there. However, if one of your lymph nodes becomes swollen or inflamed, that’s a good indicator that something is wrong.
