A scientific explanation of why breast increase in size and become more sensitive before menstruation.
Breasts get bigger during menstruation due to hormones (jlp)
Hormones are the reason. Higher level of estrogen can cause a histamine-like effect on microcirculation (microcirculation is the blood flow through small blood vessels). Increased breast blood flow some days before the menstruation is the result.
A breast's volume can increase by 6 to 12 inches during menstruation (jlp)
Breast volume can increase by 6 to 12 inches! The feeling of tension is caused by proliferation (proliferation is fast division or reproduction of cells) of glands under the influence of estrogen and progesterone.
The smallest breast volume is between the fifth and seventh day of menstruation (jlp)
During menstruation the hormone level drops. Lobuli (microscopically small gland pouches) get smaller, and lacteal tubes get narrowed. The smallest breast volume is between the 5th and 7th day of menstruation.
