First of all, calm down. Do not worry a lot as even if your Mother and your aunty got breast cancer
, does not mean that you are going to get breast cancer. Every person has genes which can cause cancer but there are genes which stop cancer from starting.
The most common cause of pulsating pain in breast can be when you would be having your menses in a week's time.
To check whether your breasts are normal, use your palm and feel your breasts with your palm and move your palm in a clockwise direction from sides to the center of nipple and then in anticlockwise direction from nipple to side. In this movement, if you feel everything as soft, then there is nothing to worry.
In the end, to remove out any doubts, you can have a mammogram
done. Mammogram is a easy procedure and is painless too. It is just a Ultrasound sonography
of the breasts. All your doubts will get cleared by a mammogram.
