Pressing the breast and seeing watery fluid come out is often related to nipple discharge, which can have both normal and abnormal causes. Normal causes include stimulation of the nipple, hormonal changes (like during pregnancy or menstrual cycle), and sometimes after breastfeeding. The discharge may be clear or milky and is typically not a cause for concern if it is bilateral and without other symptoms. However, abnormal nipple discharge can be caused by several conditions like infections, benign breast tumors (intraductal papillomas), mammary duct ectasia (dilated milk ducts, often around menopause), or hormonal imbalances such as galactorrhea. Discharge that is bloody, comes from one breast, occurs spontaneously without pressing, or is accompanied by breast pain or lumps should be evaluated by a healthcare professional to rule out serious conditions including breast cancer. If the fluid appears only when pressing and is watery or milky, and no other symptoms like pain or lumps are present, it is often benign. Nevertheless, any new discharge or discharge that persists should be checked by a doctor for proper diagnosis and treatment if needed.

Key Causes of Watery Discharge When Pressed

• Nipple stimulation or squeezing
• Hormonal changes (pregnancy, menstrual cycle, prolactin hormone)
• Residual milk secretion after breastfeeding
• Fibrocystic breast changes
• Benign growths like intraductal papilloma
• Mammary duct ectasia

When to See a Doctor

• Discharge is bloody or from one breast only
• Discharge occurs without any pressure or stimulation
• There is a lump, pain, or skin changes in the breast
• Discharge persists for weeks or worsens

It is recommended to stop pressing the nipple repeatedly as this might worsen discharge, and consult a healthcare provider for a thorough evaluation.
