Maybe fibre, irregular shape in my right breast when doing an ultrasound. mom had breast cancer 4yrs ago and her aunt before. is a mammogram needed?

Check: Probably ok at your age. See your doc. Mammogram at your age not usally helpful, but may need an ultrasound .

Probably not: For the average risk woman, screening mammo should begin at 40. For very high risk patients, for example BRCA gene carriers, screening can begin earlier. Have your doctor assess your risk profile to see where you fit in.
