This may sound little weird, but actually it is very true. Quick self-exam is an easy way to check for swollen lymph nodes or some other bumps and lumps that could cause cancer.
You should know that these glands are commonly found in the groin, armpit, back ear and neck and are very important part of our immune system and protect our body from diseases and infections. So, this means that by checking the lymph nodes in your neck, you can predict if there are risk for parasites or cancer.
Lymph nodes are usually small and kidney-shaped glands. They transport waste, fluids and nutrients from the bloodstream and body tissues. Lymph nodes are not painful at all, and even sometimes you cannot locate them. But, if lymph node become inflamed and swollen, it is an indicator that something is wrong with your body.
