Nobody can tell you any thing about your swollen lymph node without having a look on the x-ray, location of lymph node, your sex and medical history. If it is is really swollen lymph node then it can be due to infection and Hodgkin lymphoma. This lymphoma can cause swelling in lymph nodes of neck, armpit, groin and chest.
In my opinion, any growth any where in the body should not be neglected. You should get second opinion and get further investigations to avoid any future complications.
