Dr said it takes 3 months for breast tissue to go back to normal after stopping breastfeeding which is why i have to wait for mammogram. true?

True: This is true but if you have an abnormal lump, the an ultrasound can be done. At 25 (if this is your real age), you should not need a mammogram unless you are high risk.

True: We usually recommend 6 months for screening. Are you 26? You are too young for screening unless you are a BRCA carrier. If you have a lump, ultrasound would be the imaging study of first choice anyway.
