After 2008 auto accident, a lump appeared in the left breast 6 o'clock. Injury from seat belt and air bags caused breast tissue damage, rippling and breaking of muscle tissue that hold the breasts -up. Local mammogram and sonnogram screening showed NO changes from my 2005 mammogram...Would tissue changes show on these tests? Can the accident contribute to the increased cause of cancer later on? No previous history
(and no family history) of lumps or cysts.
