Hi, I am 54 and was told that I have dense breasts, as well. I have a mammogram every year because [breast and other] cancers run in my family. I know that seeing your doctors, especially when you have had specific issues is vitally important. I have not been diagnosed with any issues with my breasts, other than being told that they are dense, but due to a motorcycle accident years ago I have had a lot of experience with doctors and other therapists over the become a believer that if you don't feel good about one [or more!] of your doctors or therapists, there is usually a good reason for this. It might be that they don't know as much as they would have you believe, maybe they have made a false call about something and ae trying to cover-up their mistake, or they simply don't know what they are doing.
