You are me! I had this happen only was told that I had a BiRad of 5! I saw a breast surgeon who told me why and my calcifications were numerous, shaped in such a way and grouped in such a way that they were highly suspicious. I scheduled a needle biopsy. I will tell you, NO CANCER. I did not have cancer. It's been over 10 years and STILL do not have cancer with a mammogram just a couple of months ago. I know it is scary and you are very worried, but this does not mean that you have cancer, just that they need to investigate further. Are you getting a biopsy soon?
4A: Low suspicion for malignancy (more than 2% but no more than 10%)
4B: Moderate suspicion for malignancy (more than 10% but no more than 50%)
4C: High suspicion for malignancy (more than 50% but less than 95%)
Groups of amorphous calcifications are technically 4B. With grouped calcifications, the primary diagnostic consideration is ductal carcinoma in situ (DCIS), which is noninvasive or preinvasive, the earliest form of breast cancer. So basically, in the worst case scenario, your scenario is not that bad. For more details, please refer to the following article:
Bi-rads 4 means that there is a little bit chance of cancer, but it also means a 60% to 70% chance of not having breast cancer.
So be positive and stay calm, if you're worried that you may have breast cancer due to family history of cancer then get it checked on a regular basis.
Thinking of you MsWags. I hope you are doing alright after the surgery yesterday.
