My grandmother had breast cancer, does that mean I'll have it?

My grandmother from her father had breast cancer, does that mean I'll have it too? Because I feel a lot of pain in my breasts and I'm worried because I'm 33 years old and I have not had a mammogram yet, I already had an ultrasound and the doctor did not find anything is normal these pains?
Expert answer:

If your grandmother had breast cancer means that your chances of having breast cancer are greater than the chances of a woman with no family history of breast cancer, but not to say that she will have it, only the chances are higher. No pain is normal.
