Lymph nodes are small, bean-shaped structures that are part of the immune system. The lymph nodes’ job is to protect the body from infection by filtering viruses and bacteria and stopping them from spreading. In order to completely protect us, there are hundreds of lymph nodes throughout the body.
Your Treatment Options
The treatment for swollen lymph nodes is decided after determining the cause of the swelling. In many cases, the cause of a swollen lymph node is an infection. If it’s a bacterial infection, your provider will prescribe antibiotics. These will help treat the infection and return the lymph nodes to their normal size.
In some cases, a swollen lymph node may be due to cancer. If your provider is concerned about this, they may request a biopsy. During a biopsy, a piece of the lymph node will be removed and analyzed for cancerous cells. If cancer has been detected, surgery or other treatments will be required.
