Nipple discharge and cancer

Nipple discharge and cancer

According to the International Journal of Preventive Medicine Reliable Source, nipple discharge can be a sign of breast cancer.

According to the same study, between 7 and 15% of women who report nipple leakage of unclear origin will develop breast cancer.

Nipple discharge refers to the release of fluid from the nipple. While it can sometimes be a normal occurrence, it can also be a sign of an underlying medical condition. Here are some potential causes of nipple discharge:

Pregnancy and breastfeeding

During pregnancy, the breasts undergo changes in preparation for breastfeeding. Nipple discharge can occur during pregnancy and after childbirth due to the production and release of milk.

Stimulation

Nipple discharge can be triggered by frequent stimulation of the breasts or nipples, such as during sexual activity or breast examination. This is typically harmless and temporary.

Hormonal imbalances

Hormonal fluctuations can cause nipple discharge. Conditions such as thyroid disorders, excessive prolactin production (hyperprolactinemia), or hormonal therapies may lead to abnormal nipple discharge.

Infection

Infections, such as mastitis or a breast abscess, can cause nipple discharge. These conditions are often associated with additional symptoms like breast pain, redness, swelling, and fever.

Ductal ectasia

Ductal ectasia is a condition in which the milk ducts beneath the nipple become widened and blocked. It can result in nipple discharge that may be thick, sticky, or greenish in color. Other symptoms include nipple inversion, breast pain, and inflammation.

Fibrocystic changes

Fibrocystic changes in the breast refer to the development of noncancerous lumps or cysts. These changes can cause nipple discharge, usually clear or cloudy in appearance, along with breast pain or tenderness.

Benign breast tumors

Certain types of benign breast tumors, like intraductal papillomas or adenomas, can cause nipple discharge. These growths can obstruct the ducts and lead to the discharge of blood or a clear fluid from the nipple.

Medications

Some medications, such as certain antidepressants, antipsychotics, and high blood pressure medications, can cause nipple discharge as a side effect.

Breast cancer

While nipple discharge is more commonly associated with benign conditions, it can sometimes be a sign of breast cancer. In such cases, the discharge is often bloody or serous (yellowish fluid). However, most cases of nipple discharge are not cancer-related.

This implies that the cause of nipple discharge is not cancer for the great majority of women. However, ductal carcinoma in situ or papillary carcinoma are the most often identified diseases in women with malignant nappy discharge.

A doctor would often advise getting an imaging scan to make sure no malignant lesions are present if they cannot identify a clear benign underlying cause for nipple discharge. 

A person with nipple discharge who has a greater chance of developing breast cancer owing to family history should consult their doctor as soon as feasible.

If you're experiencing nipple discharge or have concerns about your breast health, it is advisable to consult a healthcare professional for an evaluation and appropriate diagnosis. They will be able to provide you with a proper assessment and guide you through any necessary investigations or treatments.
