I understand your concern and I'm sorry to hear about the accident. You are correct that this type of trauma may take some time to heal, and this might result to a residual firm or hard lump in that area of the breast. However, there is no direct evidence that trauma to the breast results to breast cancer. What is actually happening is that the breast trauma will prompt a woman to examine her breasts, and in so doing, some would detect lumps or cancers that are already there in the first place, even before the traumatic event. I suggest you follow up with the doctor regularly to monitor the healing process, but at the same time, not to worry too much that this might lead to cancer. Hoping for your full recovery.
Regards and God bless.
