[|AI|]  Hello! Welcome to Chat Doctor. You haven't mentioned your sex & is there any fever? Usually ganglion is found over area where there is tendon like wrist but is unlikely in armpit. This can be an enlarged lymph node. If fever is there, infection is there and this goes again in favor of enlarged lymph node. Source of infection needs to be ad Chat Doctor. In a female, breast is more common site of infection. Breast malignancy giving rise to lymph node metastasis is unlikely at the age of 23 but can not be ruled out without examination. Consult your doctor early. Hope this information is useful for you. Wish you healthy life. Thanks. Regards.
