Dear lp2408, When a person has nipple discharge there are certain situations that are of more concern and should be followed up on to determine what is the cause of them. These situations include: when the discharge is spontaneous (fluid comes out on it's own without squeezing), if the discharge is bloody, or it is sticky (like an egg white). Bloody discharge could be due to benign conditions such as a papilloma (wart-like structure within the duct), however it might also be due to a pre-cancerous condition, or cancer. Cancers are rarely the cause of discharge, however having this followed up to be sure of the cause is prudent.
