Many adults in the U.S. are not getting the recommended screening tests for colorectal, breast and cervical cancers, according to data published in the Centers for Disease Control and Prevention’s (CDC) Morbidity and Mortality Weekly Report. For 2013, screening for these types of cancers either fell behind previous rates or showed no improvement.

Not counting some kinds of skin cancer, breast cancer is the most common cancer in women in the United States, according the U.S. Centers for Disease Control and Prevention (CDC), which is using the month of October to urge women to get mammograms on a regular basis.
