A firm squeeze of the breast stripping the ducts towards the nipple may produce in many cases a nipple discharge.
Normally, there will be one or two drops of clear, milky or green-tinged secretions.
woman's breasts secret some fluid throughout most of the adult life. The difference between lactating (milk producing) and non-lactating breasts is mainly in the degree or amount of secretion and to a smaller degree the chemical composition of the fluid. In non-lactating women, small plugs of tissue block the nipple ducts and keep the nipple from discharging fluid. Nipple discharge are often yellow, green, brown, bloody, or milky in appearance.
Nipple discharge is not in principle a cause for alarm even if it is the third reason women seeks medical assistance concerning breasts.
Suspicious Nipple discharge is if:
* bloody or watery (serous) with a red, pink, or brown color
* sticky and clear in color or brown to black in color (opalescent)
* appears spontaneously without squeezing the nipple
* persistent
* on one side only (unilateral)
* a fluid other than breast milk
My advice is starting to do yourself her monthly breast exam and incorporate that practice on it.anyway, touching, palpating and even squeezing the breasts are not a dangerous practice concerning "getting cancer risk" and the intensity of that depends on the partners tastes and on their dialog...
