Is it possible to get breast cancer from something hitting your boobs?

No: What usually happens is that one would pay more attentions to the breast and examine it frequently due to the trauma ( got hit by something) and she then accidentally finds a lump or mass on the breast. The lump most likely has been there for a while and not related to the trauma.

No: No, an isolated breast trauma has not been linked to breast cancer but if you have concerns about a bruised area or a lump, it is best to have it looked at by your pcp or our breast surgeon. They will likely order an ultrasound and mammogram to get baseline information and ruling out tumors.
