Clear nipple discharge is often caused by benign factors such as hormonal changes, breast stimulation, certain medications, or non-cancerous conditions like duct ectasia. In most cases, it is not a sign of breast cancer. However, if the discharge is spontaneous, persistent, bloody, or occurs in only one breast, it should be evaluated by a healthcare provider.

Because nipple discharge can have many possible causes, understanding your specific symptoms is the first step toward peace of mind and appropriate care. Take a free, instant, online symptom check to better understand what may be behind your symptoms and get clear guidance on your next steps.
