What Causes Bloody Nipple Discharge?
Bloody nipple discharge can have various causes, ranging in severity from 'needs attention' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose bloody nipple discharge, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.

|Some medications can cause non-bloody nipple discharge. The most common culprits are cimetidine (for stomach problems), oral contraceptives, some antidepressant and other drugs for psychological problems, and domperidone (for nausea). Even if you have not noticed any blood, your doctor may ask you to try to squeeze a few drops out, and will test it for microscopic blood.|Breast Cancer
|Nipple discharge can be a symptom of breast cancer, particularly if it is bloodstained. You should definitely discuss any nipple discharge with a doctor – especially if you are a man, because the usual cause is a tumor and you will need treatment.|
