Is There a Relationship Between Nipple Discharge and Breast Cancer?
Nipple discharge, although rarely, can be a symptom that needs to be evaluated for breast cancer. However, not every nipple discharge means cancer and is mostly caused by benign reasons. These discharges can occur due to the physiological functions of the secretory glands, hormonal changes, or infections. In evaluating whether nipple discharge is related to cancer, the color of the discharge, whether it is unilateral or bilateral, its amount, and accompanying structural changes in the nipple are taken into consideration. In suspicious cases, a physician should be consulted without delay, and necessary diagnostic and imaging methods should be applied.
What Are the Causes of Nipple Discharge?
- Hormonal changes
- Infections
- Medications used
- Blockages in the breast ducts
- Dilation in the milk ducts (ductal ectasia)
- Intraductal papillomas
What Are the Types of Nipple Discharge?
- White discharge developing due to hormonal changes
- Green, yellow, or brown discharge due to infections or blockages
- White or clear discharge related to milk ducts
- Bloody or watery discharge due to intraductal papillomas
- Discharges developing as a side effect due to medications used
Is Nipple Discharge Associated with Cancer?
Nipple discharge does not always mean cancer. Most nipple discharges are caused by benign reasons. However, since it may be associated with cancer in some cases, a proper evaluation can only be made after a physician's examination and necessary tests. Especially in bloody or unilateral, continuous discharges, medical evaluation is absolutely necessary.
How is Nipple Discharge Evaluated?
In the evaluation of nipple discharge, the color, amount, whether it is unilateral or bilateral, and other accompanying symptoms are taken into consideration. During the diagnostic process, the patient's medical history is listened to, a physical examination is performed, and imaging methods are used if deemed necessary. The main methods used are:
- Medical history and symptom evaluation
- Physical examination
- Breast ultrasonography, mammography, and MRI if necessary
- Pathological examination of the discharge sample
- Treatment planning according to the findings
Which Nipple Discharges Require Medical Evaluation?
Bloody Discharge: Bloody discharge from the nipple can be a symptom of some serious breast diseases. Therefore, it needs to be evaluated by a physician.
Unilateral and Continuous Discharge: Discharges coming from only one breast and continuing for a long time should be examined for an underlying pathology. This situation is of clinical importance.
Mass or Swelling in the Nipple: In the presence of a palpable mass or swelling accompanying the discharge, further investigation may be required. These findings should be evaluated carefully.
Other Accompanying Symptoms: Discharges seen along with color changes, pain, or shape changes in the breast skin can be indicators of different breast diseases and require evaluation.
