I Have a Foul Ordor Coming from my Breast? (photo)

In viewing your photo it appears that you have a severe infection. You should consult with your doctor immediately.

      Although the risk of nipple areola necrosis and fat necrosis after breast reduction is very small, additional areas of necrosis should be conservatively debrided.  Any foul odor can be a concern for infection, but necrotic tissue produces a foul odor as well.  Whenever there is a concern for infection or an additional area of necrosis, a visit to the surgeon's office is in order.

You have necrotic (dead) tissue in the breast you have pictured. The foul odor is a result of bacterial colonization of that tissue. The foul odor can also be caused by a more sever infection, which is hopefully not the case. Either way, you should be seen by your doctor urgently, and the necrotic tissue should be further debrided til the open wound is clean and there is no more foul smell. Best of luck to you.
