Nipple discharge is a common clinical concern that frequently leads to significant anxiety. In Singapore, where breast health awareness is high, many individuals immediately associate any form of breast fluid with malignancy. However, medical research indicates that the majority of cases are related to benign conditions. To provide clarity, we address five of the most common nipple discharge myths.

Myth 1: Nipple Discharge Always Indicates Breast Cancer
This is the most prevalent misconception regarding breast health. While nipple discharge is a recognised clinical symptom of breast cancer, it is not the most frequent cause. In fact, more than 90% of nipple discharge cases are found to be benign. Common non-cancerous causes include intraductal papillomas (small growths in the milk ducts), duct ectasia (widening of the ducts), and hormonal imbalances.
According to the Singapore Cancer Registry Annual Report 2023, breast cancer is indeed the most common cancer among women in Singapore, accounting for approximately 29.6% of all female cancer diagnoses. However, a discharge is far more likely to be a result of a benign condition than a malignant one.
Myth 2: Only Women Experience Nipple Discharge
Many believe that nipple discharge is an exclusively female health issue. This is incorrect. While it is rare, men can also experience nipple discharge. In males, any form of nipple discharge is considered abnormal and carries a higher clinical suspicion for breast cancer or pituitary gland issues compared to females. Men who notice any fluid or lumps in the breast area should seek a medical evaluation immediately.
Myth 3: If The Discharge Is Bloody, It Is Definitely Cancer
Finding blood-stained fluid can be a terrifying experience, yet even bloody discharge is often benign. The most frequent cause of spontaneous, bloody discharge from a single duct is an intraductal papilloma. These are wart-like growths that are non-cancerous but can bleed due to their fragile blood vessel structure. While blood is a “red flag” that necessitates urgent investigation by a specialist, it does not serve as a definitive diagnosis of cancer.
Myth 4: Discharge From Both Breasts Is More Concerning Than From One
Clinical evidence suggests the opposite. Discharge that occurs in both breasts (bilateral) and comes from multiple ducts is usually related to systemic issues, such as hormonal fluctuations or medication side effects. Discharge that is spontaneous, persistent, and originates from only one breast (unilateral) is actually considered more clinically significant and requires a more rigorous diagnostic work-up to rule out localised abnormalities.
Myth 5: Nipple Discharge Only Happens To Older Women
Nipple discharge can affect individuals of all ages. For instance, younger women may experience galactorrhoea (milky discharge) due to elevated prolactin levels or the use of certain medications like oral contraceptives. Furthermore, the Singapore Cancer Registry has noted a 34% increase in cancer diagnoses for individuals under the age of 40 between recent periods, highlighting that breast health symptoms should never be dismissed based on age alone. There is currently an information gap regarding the specific incidence rates of benign nipple discharge across different age cohorts in Singapore.
What Are The Treatment Options After A Diagnosis?
If a diagnostic work-up identifies the cause of the discharge, treatment is tailored to the specific condition:
- For Papillomas: A minor surgical procedure called a microdochectomy is often performed to remove the affected duct.
- For Infections: Doctors typically prescribe antibiotics. If an abscess is present, it may require drainage.
- For Hormonal Issues: Treatment involves addressing the underlying endocrine cause or adjusting medications that may be causing the discharge.
- For Malignancy: If cancer is detected, a multi-disciplinary approach involving surgery, radiation, or chemotherapy will be recommended.
