Hi, i have nipple discharge recently but now it become scab . its not painful . i have eczema which is very vad. can i know if this is cancer?

Not likely: Not likely. Did you squeeze your nipple or did it have discharge spontaneously? Spontaneous one is more worrisome but still more likely a hormone problem than cancer. If you squeeze it or have been scratching your nipple a lot from eczema, you could have stimulated your brain to cause breast milk production. Either way, you should see a doctor to get eczema under control and do a breast exam.
