Patti, I know those phone calls can be scary , however in most cases it does end up being a fatty tissue, so try not to worry.. I did have cancer it was cervical and not breast and I really believe if he thought it was something VERY serious he would get you right in... Its hard not to worry but you have to try to remain calm and pray for the best.. I had to repeat my mamo.. 2 times.. it was nothing more then fatty tissue build up , Prayers being sent your way
