A breast cancer glossary is just a dictionary that includes common terms found in breast cancer diagnosis and treatment.
Words that may be unfamiliar can make dealing with a biopsy or treatment decisions harder than they have to be. The definitions here should help you make sense out of your doctor's recommendations or your pathology report.
Use the letter codes to see terms that begin with that letter, or type the word you're looking for in the search box to look through the glossary and the rest of the site for the word you need help understanding.
This may make a breast cancer pathology report a little easier to understand so you'll know what your diagnosis and options are.
If you have any unanswered questions, make sure to write them down to ask your doctor or a member of your treatment team the next time you have an appointment.
