Q. The skin of one of my breasts has suddenly gotten dimpled, kind of like the skin of an orange. What's that about?
A. That, too, could be a sign of trouble. Sometimes a tumor causes swelling in the breast that's not easily seen, yet it's enough that the ligaments holding the breast tissue and skin together get pulled inwards by the swelling, causing your breast to dimple. Get it checked. Another visual cue: blood vessels suddenly become much more pronounced in one breast than the other.
