Usually benign: Most lesions of the armpit/axilla at your age are benign. Malignant lesions in the armpit are usually lymph nodes associated with tumors on the arm or chest wall. If no lesions present which is what appears cystic lesions of the armpit at your age are associated with swelling of the sweat glands called hidradenitis. Soaks and antibiotics can help. If no response, biopsy may be needed

Very little: very little chance of being a cancer, may need biopsy (to take the mass, cyst or lymph node out and send it to the lab for testing)
