Clear Watery discharge from my right breast

I am a 30 year old female and I just had a diagnostic mammogram as well as a ultrasound done on my right breast. I found a nodule about 5 days ago and my mother is a 9 year survivor of breast cancer. My question and concern is while they were doing the mammogram I had a clear watery discharge coming from my right breast. I have never noticed this before and didn't know if this was "normal" from them squeezing down on the breast. Any help will be excellent. Thank you

Dear Angio:  Many women have some type of nipple discharge or fluid when their breasts are squeezed or sucked, and its normal. Squeezing the nipple sends message to the brain and the pituitary gland responds by increasing prolactin levels, which in turn produces discharge from the nipple.  The discharge can come in a variety of colors - gray, green and brown as well as white.  Some women are more prone to more discharge including women on; birth control pills, certain blood pressure medications or on major tranquilizers.  These medications increase prolactin levels in the body.   There is also certain life periods when a person is more likely to get discharge than others: there may be more discharge at puberty and at menopause than the years in-between. The time to worry about nipple discharge is when it’s spontaneous (comes out by itself without squeezing), keeps on happening, and is only on one side.  If it is clear and sticky, like an egg white, or bloody.
