Squeezing white stuff from your nipples is often normal "physiological discharge," coming from breast tissue stimulation, hormonal changes (pregnancy, menstrual cycle, meds, thyroid), irritation (clothing), or even skin debris, and usually isn't a concern if it's from multiple ducts and not spontaneous; however, if it's bloody, from a single duct, spontaneous, or accompanied by a lump, see a doctor to rule out issues like infections, papillomas, or rare cancer, notes Mayo Clinic, Cleveland Clinic, and Breast Cancer Research Centre WA.
Galactorrhoea is milky nipple discharge not related to pregnancy or breast feeding. It is caused by the abnormal production of a hormone called prolactin. This can be caused by diseases of glands elsewhere in the body which control hormone secretion, such as the pituitary and thyroid glands.
Galactorrhoea is pale milky discharge coming from several milk ducts that is not related to pregnancy or recent breastfeeding. It is often abundant, spontaneous and bilateral (coming from both breasts). It can be caused by abnormal production of a hormone called prolactin.
A milk bleb is a small dot (white, clear or yellow) that can form on the surface of your nipple. You may have one dot on just one nipple or multiple dots on one or both nipples. You might hear your healthcare provider refer to these dots as nipple blebs or simply, blebs. Some people call them milk blisters.
Excess prolactin tricks your body into thinking it should lactate (or make milk), which is why you leak milk from your nipples. Other causes include: Taking medications including birth control pills, blood pressure medicine or antidepressants.
Thick or sticky discharge that is green, greenish brown or reddish brown may be caused by a non-cancerous condition called mammary duct ectasia. Yellow and foul-smelling pus may be caused by a breast infection. Milky white discharge from both breasts may be caused by some medicines or endocrine gland problems.
Nipple discharge can be alarming. But discharge that occurs only when the nipple and breast are squeezed may not be a cause for concern. The risk of cancer when nipple discharge is the only symptom is fairly low. A lump with the discharge will be of primary concern to your healthcare provider.
A nipple discharge can also be caused by breast stimulation in women who are not pregnant or breastfeeding, especially during the reproductive years. However, a nipple discharge in men is always abnormal. A normal nipple discharge is usually a thin, cloudy, whitish, or almost clear fluid.
Watch closely for changes in your health, and be sure to contact your doctor if: Your breasts continue to leak milk. The leakage looks bloody. You stop having menstrual periods, or your periods become irregular.
Etiology of Nipple Discharge
The rest result from benign ductal disorders (eg, intraductal papilloma, mammary duct ectasia, fibrocystic changes), endocrine disorders (eg, pituitary tumor), liver disorders, breast abscesses or infections, or use of certain drugs.
Normally, the natural production of breast milk (lactation) is triggered by a complex interaction between three hormones — estrogen, progesterone and human placental lactogen — during the final months of pregnancy.
The only change in advice is that you should not squeeze your nipples looking for discharge. Aggressive squeezing can result in injury and needless worry because sometimes discharge in that circumstance is normal. “The discharge that is worrisome is discharge that comes without squeezing,” Steele says.
It's normal for some mothers to notice that their baby is more efficient at draining the breast than a pump. Babies use a different sucking pattern that stimulates milk flow more effectively, so pumping output may be lower even if your breasts feel full.
Nipple discharge can cause a fluid or any other liquid to come out of your nipples. The fluid may come out of your nipples when you squeeze them, or it may even seep out on its own. In most cases, nipple discharges are not a serious cause of concern, but in some cases, they may even result in breast cancer.
Hormones, lactation or sexual arousal can be normal causes for nipple discharge. Abnormal causes could be from tumors, infection or rarely, breast cancer.
How to Clean Your Nipples Regularly
Nipple discharge can be normal in women. It's always abnormal in men. Hormones, lactation or sexual arousal can be normal causes for nipple discharge. Abnormal causes could be from tumors, infection or rarely, breast cancer.
Galactorrhea is a milky discharge from both nipples, when a person is not breastfeeding. This is often due to an increase in the hormone prolactin, which makes milk. This condition may occur if you take sedatives or marijuana.
If the spot isn't causing pain or problems with breastfeeding, you don't need to treat it—it may go away on its own. If it is painful, try these gentle tips, being very gentle with your nipple to avoid causing more damage. Don't pick at or scrape the white spot. Keep breastfeeding your baby.
It may be tempting to squeeze them, especially if they have yellow or white heads, but resist the urge. It can introduce bacteria that may lead to infection. You can wash Montgomery glands along with the rest of your nipple with soap and warm water, but avoid harsh cleansers.
Swollen Montgomery glands
Every person has Montgomery glands, though they are more apparent in some than others. These glands secrete oil to help keep the skin lubricated. At times, this secretion may resemble the pus that comes from a pimple.
You should avoid squeezing, popping or trying to unclog Montgomery glands because this could lead to infection or skin injury. Sometimes, Montgomery glands can become blocked, inflamed or infected. The signs would be a painful swelling or inflammation around the nipple and areolar area.
Areolar glands make oily secretions (lipoid fluid) that keep the areola and the nipple lubricated and protected. Volatile compounds in these secretions may also serve as an olfactory stimulus for newborn appetite.
Breast Pimples: Typically superficial, red or whitehead-like, and may have pus. They often resolve within a week or two.
Bumps can be a normal part of your nipples.
Areolas can vary in shape, size, and color depending on the person. “[Areolas] contain small, sensitive bumps called Montgomery's glands, which secrete a fluid that keeps the nipples lubricated,” explains Dr. Aliabadi. So bumps are kinda part of the anatomy.
