When will I be able to start singing again after breast augmentation surgery without affecting my healing?

This is a question that should be directed to your performing surgeon. Since each surgeon has their own post-op instructions, it’s better to ask your surgeon instead. You should also let them know if you’ll be doing physically vigorous activity (e.g dancing) at the same time as singing.

Dear monathecat,
I understand your concern. It is best that you consult your plastic surgeon regarding post operative care and management (i.e including massage techniques and timing) specific to your case. Your surgeon knows your condition well and has preferences on when and what to use for faster healing and recovery. Post operative care and management depends on the type of surgery performed and the technique used during surgery among other factors.It is best, however, that you follow your plastic surgeon's advice on post operative care management for a smooth and faster healing and recovery.

If you are traveling and have a heavy schedule, then you should wait about 4-6 weeks. If you are singing locally, then perhaps 2 weeks. If you are singing in the shower, then anytime you like. Please ask your surgeon.

This is a question best answered by your augmentation mastopexy surgeon. There is no standard for postoperative activity. My general rules after a breast augmentation is mild activity after 2 weeks, and starting back at the gym in 30 days post-op. I would think that singing may resume at the 2 week mark and more aggressive sessions at the 1 month mark.
Best wishes,.
