My wife is a doing ct scan annually after rectal surgery and the last one is two months ago and confirms cysts in breast ,shall we do mammogram ?

Depends: Cysts are usually always benign (not cancer) and ultrasound is the best imaging test for evaluation. This is only needed if they are causing symptoms (pain, enlarging, discharge). A yearly screening mammogram is recommended on any woman over 40 years of age.

CT is not: adequate for evaluating breast cysts or potential cysts. Mammography and breast sonography should be considered.
