[1] Breast cancer is most commonly diagnosed in women aged 55 to 64 years, and the risk increases with age. The recently introduced Comfort Comp feature reduces compression without notable change to compression breast thickness or glandular dose. Exceptions to this would be multiple bilateral circumscribed masses, where a benign assessment would be appropriate[13] or masses that have been stable for at least 2 years.
