Nipple discharge is a common breast condition . According to a study, 80% of women have nipple discharge at least once in their reproductive years. The severity, risk factors, and treatments depend on the nature of the discharge.

What are the Types of Nipple Discharge?

Nipple discharge categories by their types are:

  1. Normal milk production (lactation).
  2. Physiologic nipple discharge (galactorrhea).
  3. Pathologic (suspicious) nipple discharge.

All types of nipple discharge can be normal or abnormal. They may or may not require treatment, depending on individual health conditions.

  1. a)     Clear Discharge

A clear watery discharge can occur in women and men at any age. Nipple discharge due to stimulation or frequent squeezing can be responsible for a clear discharge.

Breasts have a nature to respond strongly to stimulation.

b] White Discharge

White discharge is a common condition in pregnant and nursing women. In non-pregnant and non-nursing women, white nipple discharge is still not a cause for concern. It happens as a response to breast or nipple stimulation. This milky white discharge is what doctors refer to as galactorrhea.

While nipple discharge can occur due to the following reasons:

  • Hormone-affecting medications
  • Herbal supplements like anise and fennel
  • Estrogen supplements
  • Hormonal imbalance

c) Yellow Discharge

Yellow discharge is common in women nearing menopause. The condition often arises in individuals with mammary duct ectasia. This is when the milk duct gets thicker and blocked in the walls of the breast. It further causes discharge from the nipples.

You can minimize duct ectasia with warm compressors. However, if it causes breast pain, your doctor may recommend surgical treatment.

d) Green Discharge

Green nipple discharge sometimes signifies infection. Infections majorly occur during breastfeeding or post-breast injury. A breast injury can be a sign of clogged milk ducts.

The following are the symptoms of breast infection:

  • A condition of pain, itching, burning in breasts.
  • A hot spot in the breasts.
  • Flu-like or fever symptoms.
  • Swollen spot in breasts.
  • Change in milk production.

e) Red Discharge

Red discharge from the nipple is uncommon. However, it can be frequent and at no risk in nursing parents. Yet, you should consult a doctor if it continues.

One cause of red discharge can be benign papilloma. The condition may cause lumps and unilateral discharge.

Although bloody discharge may resolve on its own, your doctor may recommend a breast ultrasound and a diagnostic mammogram to see what is causing the discharge. You may also require a biopsy to exclude a cancer and confirm that it is a papilloma . If biopsy confirms a papilloma, then your doctor may refer you to a surgeon for discussing the treatment options.

Nipple discharge often stems from a benign condition. However, breast cancer is a possibility, especially if:

  • Only one breast is affected
  • You have a lump in the breast
  • The discharge is persistent and spontaneous
  • The discharge affects only a single duct
  • The discharge has blood or is clear

When to See a Doctor?

Visiting a doctor is always advisable for any kind of nipple discharge. Even if the condition is normal and there are no alarming symptoms, it may signify underlying health issues.

Visit a doctor if you observe any of the following symptoms:

  • Breast pain and swelling.
  • Painful breastfeeding.
  • Lumps in the breasts.
  • Changes in breast shape.
  • Nipple discharge changes in colour.
  • Bloody or red discharge.

Frequently Asked Questions (FAQs)

  • Why do I have nipple discharge before periods?

Nipple discharge is a natural function of the breasts. It happens due to hormone changes. Thus, it can be associated with periods. If you have nipple discharge before your periods, there is nothing to be concerned about.

  • Are nipple discharge and late menstruation a sign of pregnancy?

No. Nipple discharge is normal during an individual’s reproductive years. Even though a woman is pregnant, nipple discharge can occur. Missing menstruation can be a sign of pregnancy, but it does not necessarily mean you are expecting a baby. Moreover, there is no proven evidence that says nipple discharge indicates pregnancy.

  • Is bloody nipple discharge a sign of breast cancer? 
  • No. A bloody nipple discharge is not always  a sign of breast cancer. However, if you experience a frequent red discharge along with other symptoms, you should visit a doctor to know the causes and prevent breast cancer. 
  • What is the link between hormones and nipple discharge?

The discharge unrelated to pregnancy is called Galactorrhoea. The situation arises due to excessive production of prolactin. However, when a woman gets pregnant, she experiences hormonal changes that produce colostrum. In some cases, if you are taking estrogen supplements, you are more likely to experience nipple discharge due to imbalanced hormones.
