A member asked:

Is there another reason other than pregnancy for breasts to swell?

A doctor has provided 1 answer

Swelling: Breasts usually respond to hormonal changes especially to the hormone progesterone. Progesterone causes the body to retain water. For this reason , you usually gain weight after ovulation and before your periods. Occasionally swelling can be from an infection or rarely, a malignant process.
