I've been going thru this with them for about 5 years. First, it's the right breast. Now, it's the left breast. They call you back for extra films which includes extreme compression. Which is very painful. Then, usually a day or 2 later, they call you for a sonogram. Of course, after the sonogram they say that what they saw was just dense breast tissue. Isn't it strange that after 4 years of going thru this it's always ""dense breast tissue"". If my right breast has dense breast tissue, it shouldn't be a suprise that my left breast also has dense breast tissue. It makes sense to me. I don't think they do it for the insurance money. I think that they do it because they are afraid to get sued. Apparantly they have litigation pending.
