Could i have best cancer if i have liquid coming out of one breast?

Plz See Your Dr. : Discharge is a pathologic process caused by a tumor or inflammation within a duct; secretion is a physiologic process. Discharge tends to occur spontaneously, from one duct orifice& is clear or bloody; secretion is elicited, milky-green, &bilateral. ~10% of discharge may be secondary to cancer, although this # goes down if mammogram and exam are normal. Pap smear of fluid or duct excision helpful.

The character: Of the discharge can be helpful. At your age varied periods can be normal, but nipple discharge and amenorrhea can be a sign of a pituitary tumor. You are at an age where an annual mammogram is a good idea as well. If normal, check with a breast surgeon anyway.
