This is Dr. David
I am a cancer doctor.
breast cancer would be unlikely in this situation
much more likely for the hematoma to be causing a bit of the blood coming out of your nipple.
you should try some cold compresses on your breast to help decrease swelling
this could over time help slow down your milk production as welll
you should ask for a breast ultrasound to make sure your hematoma is getting better
sometimes breast hematomas can take weeks to months to get better
let me know if you have other questions.
