During the clinical breast examination, which of the following is a normal finding?
1. Pronounced unilateral venous pattern.
2. Peau d’orange breast tissue.
3. Long-term, bilateral nipple inversion.
4. Breast tissue that is darker than the areolae.
It is a normal variation for women to have long-term, bilateral nipple inversion. A woman who has a unilateral nipple inversion that is a new change is at risk for a tumor; the weight of the tumor causes pulling on the nipple. A pronounced unilateral venous pattern, peau d’orange breast tissue, and breast tissue darker than the areolae are definite warning signals for breast cancer that must be reported to the physician immediately.
