Editing Nipple (section)

===Discharge===
Nipple discharge refers to any fluid that seeps out of the nipple of the breast. Discharge from the nipple does not occur in lactating women. And discharge in non-pregnant women or women who are not breastfeeding may not cause concern. Men that have discharge from their nipples are not typical. Discharge from the nipples of men or boys may indicate a problem.  Discharge from the nipples can appear without squeezing or may only be noticeable if the nipples are squeezed. One nipple can have discharge while the other does not. The discharge can be clear, green, bloody, brown or straw-coloured. The consistency can be thick, thin, sticky or watery.<ref name = medline1/><ref>{{cite web|url=http://www.mayoclinic.org/symptoms/nipple-discharge/basics/definition/sym-20050946|title=Nipple discharge|publisher=[[Mayo Clinic]]|access-date=12 August 2017}}</ref>

Some cases of nipple discharge will clear on their own without treatment. Nipple discharge is most often not cancer (benign), but rarely, it can be a sign of breast cancer. It is important to determine what is causing the discharge and to get treatment.

* Pregnancy
* Recent breastfeeding
* [[Fissure of the nipple|Rubbing]] on the area from a bra or T-shirt
* Injury to the breast
* [[Mastitis|Infection]]
* Inflammation and [[blocked milk duct|clogging]] of the breast ducts
* Noncancerous [[pituitary tumor]]s
* Small [[breast mass|growth]] in the breast (usually not cancer)
* Severe underactive thyroid gland ([[hypothyroidism]])
* [[Fibrocystic breast changes|Fibrocystic breast]] (normal lumpiness in the breast)
* Use of certain medicines
* Use of certain herbs, such as anise and fennel

Sometimes, babies can have nipple discharge. This is caused by hormones from the mother before birth. It usually goes away in two weeks. Cancers such as [[Paget's disease of the breast|Paget's disease]] (a rare type of cancer involving the skin of the nipple) can also cause nipple discharge.<ref name = medline1/>

Nipple discharge that is not normal is bloody, comes from only one nipple, or comes out on its own without squeezing or touching the nipple. Nipple discharge is more likely to be normal if it comes out of both nipples or happens when the nipples are squeezed. Squeezing the nipple to check for discharge can make it worse. Leaving the nipple alone may make the discharge stop.<ref name = medline1/>

Nipple discharge in a male is usually of more concern. Most of the time a mammogram and an examination of the fluid is done. A biopsy is often performed. A fine needle aspiration (FNA) biopsy can be fast and least painful. A very thin, hollow needle and slight suction will be used to remove a small sample from under the nipple. Using a local anesthetic to numb the skin may not be necessary since a thin needle is used for the biopsy. Receiving an injection to prevent pain from the biopsy may be more painful than the biopsy itself.<ref>{{cite web|url=https://www.cancer.org/cancer/breast-cancer-in-men/detection-diagnosis-staging/how-diagnosed.html|title=How Is Breast Cancer in Men Diagnosed?|website=www.cancer.org|access-date=12 August 2017}}</ref>

Some men develop a condition known as [[gynecomastia]], in which the breast tissue under the nipple develops and grows. Discharge from the nipple can occur. The nipple may swell in some men possibly due to increased levels of estrogen.<ref>{{Cite journal|last1=Cuhaci|first1=Neslihan|last2=Polat|first2=Sefika Burcak|last3=Evranos|first3=Berna|last4=Ersoy|first4=Reyhan|last5=Cakir|first5=Bekir|date=2014|title=Gynecomastia: Clinical evaluation and management|journal=Indian Journal of Endocrinology and Metabolism|volume=18|issue=2|pages=150–158|doi=10.4103/2230-8210.129104|issn=2230-8210|pmc=3987263|pmid=24741509 |doi-access=free }}</ref>
