Small lump underneath left nipple

[Dean619]

Hi there, I am a 26 year old fit and healthy male. I found a small lump under my left nipple several months ago. The nipple is also tender. I initially put this down to being gyno due to me training a lot in the gym resulting in an increase in testosterone. I have no other symptoms other than the lump and tenderness to touch. I would say the lump is slightly bigger than pea size. I have booked an appointment at the doctors but that’s over a month away. Does this sound serious enough to warrant booking an emergency one to get seen asap?

Many thanks

Lumps caused by breast cancer CAN be painful, but rarely are: https://www.cancer.org/latest-news/breast-cancer-symptoms-what-you-need-to-know.html

It sounds more like a cyst.  If it's growing in size or the pain increases, I'd see urgent care as it may be the result of an infection, but otherwise, I'd just keep the pre-scheduled appointment.
