question: My 88 yr. old mother has a golf ball size lump in anterior axilla area, diagnosed as hematoma, saw general surgeon who drained 30cc of dark red blood and then it refilled and he drained 25 cc of blood, and advised surgery. He is not sure of why the refill of blood. CT scan and mammogram indicated "hematoma" . This started Aug.6. and seen by surgeon on 9/2. Any ideas of where the blood is coming from? Should we consult a vascular or other surgeon for 2nd opinion?   Thank you.
