Fibroadenoma with florid intracductal hyperplasia

Hi,
I'm 20 years old and I have a history of a fibroadenoma with florid intraductal hyperplasia. I went for my 6 month biopsy follow-up using ultrasound. My results state that the tumor has grown mildly (about 3 mm all around) and that it may be prudent to surgically remove it. I will be seeing a surgeon on the 29th. Can you please give me an idea of what this all means. Can my florid hyperplasia turn into Atypical? Is this something serious to worry about? Can I develop breast cancer within a few years? Cancer in general runs in my family like mad. My 19 yr. old male first cousin  recently had his testicles removed due to testicular cancer, my 28 year old male first cousin past away 4 years ago with sarcoma. I don't know if the high cancer rate in my family will influence any chances of me getting breast cancer.
What does echogenic nodule mean? What does greatest diameter mean? If you could help clear some of these questions I would be most at peace. Thank you!!! :o)

Dear Morgan Ashly:  Fibrooadenomas are distinct on a mammogram or ultrasound and when aspirated - no fluid comes out. A physician can generally tell whether a lump is a fibroadenoma by feeling it. As long as the doctor is sure it is a fibroadenoma, there is no need to remove the lump. In 50% of the cases fibroadenomas will go away on their own within 5 years. In others, the life of a fibroadenoma is about 15 years. In teenagers - the tendency is not to remove fibroadenomas. In middle age women, the tendency is to remove the fibroadenomas to be sure they are, in fact, fibroadenomas.

Florid hyperplasia essentially means overactive breast tissue.  It does not turn into atypical.  But that does not mean that the conditions do not exist to form other types of hyperplasia.  It does not mean you have cancer.  Echogenic nodule means it shows up on ultrasound.  Greatest diameter means that...when measured in 3 dimensions the largest is the greatest diameter.
