Nipple Discharge

I have had nipple discharge from one breast only.  I am 34 no history of any cancer in family.  I get this discharge only when I squeeze the nipple.  Two times I squeezed and from on area on the nipple it was green then immediately went back to milky color.  I had an occult test (negative), breast exam (negative), mammogram (negative) and u/s (negative). Can I sort of put cancer out of my mind?

Dear JillP: Many women have some type of nipple discharge or fluid when their breasts are squeezed, 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

But, it's coming from one breast.

Hi Jill,
don't worry that it is coming from just one breast - the other factors mentioned are much more important than the one sidedness - I had the same thing - but like you was checked and all is normal.  Also the key thing is if it is like egg white or bloody which yours is not. I am 30 and also have similar discharge to you - again, only if squeezed this is more on one side than the other.  Glad I saw this site and the comments.
