Very uncommonly” do women have nipple discharge or blood coming from their nipples, said Dr. Adam Brufsky, a professor at the University of Pittsburgh School of Medicine. However, he added that bloody nipples do not necessarily indicate cancer.

Dr. Margaret Chen, a breast surgeon at NewYork-Presbyterian/Columbia University Medical Center, said that asymmetry and pain are less common symptoms of cancer. She stressed the importance of routine mammograms, given that there are often no warning signs.

Skin redness and feeling warmth in the breast are both rare breast cancer symptoms, according to Spring. She advised women with any questions or concerns to see a doctor.
