How is the fibrocystic disease diagnosed?

Sweat Chloride: If you are referring to cystic fibrosis, the standard diagnostic test is to conduct 2 back-to-back sweat chloride tests. These tests measure the amount of sodium and chloride in the sweat content; levels of 60 milliequivalents per liter or above are considered diagnostic. The disease can also be diagnosed by running a genetic test, but this is more expensive.

Exam and images: All breasts are fibrocystic but some of us will have more lumpiness and/or pain. A good evaluation by a breast specialist along with and ultrasound (since you are so young) can make the diagnosis. This is not a precursor to cancer. Fibrocystic breast condition (i don't use the word disease in this instance) is more common than breast cancer.
