Digital mammography is the best out there these days for imaging of breasts. Be sure you go to an institution that has an onsite Radiologist with MRI and Ultrasound capabilities for possible biopsy. Prognosis depends on what type of Ca and what stage it’s in. (been there, done that, Seminoma Grade 2A-B survivor)
My wife’s surgeon says that there aren’t that many radiologists that can properly read breast MRI’s. The one used by the Comprehensive Cancer Center in Palm Springs, CA has one of the best in the country, and everyone at the clinic makes you feel right at home...absolutely wonderful people, all of them.
