Black spots on Xray

I have recently had a mamogram (mammogram) and been told ( and seen on it) I have several cysts on each breat, largest 12mm, and under my arms. NO need to worry at this point.
BUT I also have had a pelvic X-ray about the same time which happen to include a full body x-ray shot (Phillips brilliance - dye type exray) that shows all the" cysts"  as black spots (not white ones) very clearly.
Is it cancer, not simply cysts???? (Breast cancer is in the family - my mim!!!)

Different types of X-ray exams demonstrate things differently on film. Cysts are cysts and they are a benign condition and no cause for concern. Was there a problem that called for the pelvic X-ray; and why a full body X-ray .... that's a lot of exposure to radiation unless there was a serious condition that warranted this.  If you aren't comfortable with the reading of your mammogram you might either request an Ultrasound OR ask that your mammo films be read by another Radiologist.
