Hi,
A BIRAD 2 means that the lesion looks to be more benign and regular follow ups would be required.
You can carry on with regular breast self examinations and then follow up periodically with your doctor and also report any abnormal features you notice on breast self examination like a breast lump, nipple discharge or skin changes.
Let us know what your doctor advises and if you have any other doubts.
Regards.
A BIRAD Score of 2 is Good. I see the word "negative" and that is good also. If you would like to research this you might put the term "BIRAD Score" in search .. the numbers go from 0 to 5 and each will be explained.
