Breast abscess | lactation. The issue?

Hello, My wife had a baby on 7th March (normal delivery). Since 2 weeks she's having engorged breast (right) and have severe pain. We went to a surgeon and after scan, it was diagnosed as infected galactocele leading to abscess. Doctor prescribed antibiotics and painkillers which we are using for almost 10 days. She's still having severe pain and swelling. We met the doctor again and they confirmed that the infection has gone but the water is left inside the breast. Suggested to have a surgery (told us that the surgey could be risky in the situation) or to stop lactation using medication. We tried various methods to decrease swelling like warm compress, cold cabbage etc and she's been expressing and feeding the baby. Help us in taking in the right decision, can stopping lactation solve the issue? Thanks!
