nodes are normally present in all individuals in various body parts and one of them is the location that you have described (inguinal area). There can be a number of reasons for enlargement of these nodes like infections, TB, filariasis
, trauma, cancer in the draining area. They are naturally enlarged in bare foot walkers. If you have no other symptoms (like lesions on the limb/penis/vulva/perianal area, discharge or bleeding per urethra/vagina/rectum
, abdominal pain
, etc), then the likelihood of these nodes being cancer is remote. However it is advisable for you to consult a surgeon as only after a thorough examination can a final opinion be given.
