There was a small drop of blood that I believe came from my left nipple. The breast ultrasound was negative so I never bothered coming back for the result of the mammogram I took last November 2015. Is the result only relevant within a time frame from the date of the procedure?

Hi, Joan! I do hope that it is nothing serious but as for your query, i would suggest to still seek your doctor to ensure your health and safety. You may discuss with your doctor about how often should you (or shouldn't) undergo the mammogram test basing on your personal preferences, medical history as well as your individual breast cancer risk. Based on research, mammogram isn't so accurate and perfect so it is still best to always have a checkup and talk to your doctor.
