6. Nipple Sensitivity
As the most common site for tumor in the breast is just below the nipples, one can notice considerable changes in their shape and appearance. Some women may notice their nipples not sticking enough as they once used to. Nipple sensitivity is one sign which comes to the notice of men or women mostly during sex. The nipple can become scaly and inflamed. Inverted or indented nipples shouldn’t be ignored as they are serious signs of breast cancer.
