I Had A Mammogram 2 Weeks Ago. This Is My

I had a Mammogram 2 weeks ago. This is my 2nd Mammogram during my lifetime, the 1st was 3 yrs ago. the mammogram I had done this time utilzed Tomosynthesis. after the test was done and the tech was looking at it, she said to me "see that white spot with the movement going through it....thats not good" now I have been called back for additional views (even though she took more pictures before I had left). should I be concerned about breast cancer
