Dear shas, Bloody discharge is a finding that should be evaluated, it is not a normal symptom. You'd want to discuss this with your doctor so they can evaluate why this is occurring.
I had bloody discharge from my breast, and I found I had in situ ductal carcinoma and Inflamatory breast cancer. You definitely need to get it evaluated ASAP.
bloody discharge is not normal under any circumstance, and needs to be evaluated. The majority of women with bloody discharge turn out to have something other than cancer, but you can't know for sure without more tests. If it were due to cancer, the likelihood it would be a new one rather than spread from the other side.
