I have a swollen lymph node in groin for almost a wk now. how long does it normally take to go away? after how long with it should i go see a doctor?

Possible tumor: Swollen lymph node in groin should not be present. With tumor or infection there is always a source that can be noted. Perianal lesions to low pelvic growths to mid thigh pathology result in lesion in groin. Lymphomas arise de-novo in gland and as such if lesion enlarges or more than one appear,, surgeon should evaluate for bx.
