Explain why mammography provides a sharper image of postmenopausal versus young breasts
What will be an ideal response?
Fibrous and glandular tissues appear as white interlacing strands on a mammogram; fatty tissues appear dark; and cysts and tumors appear as white, well-circumscribed masses. A postmenopausal breast has more fatty tissue that provides a sharper contrast to the lesser amount of fibrous and glandular tissue. A young breast has more fibrous and glandular tissue than fatty tissue such that there is lesser contrast provided to easily detect suspicious masses.
