i just had a Qbank question that asked me for the 3 most common causes of cancer in women. i chose "lung, breast, ovary"...but the right answer was "breast, lung, colon, rectum"....does anybody have a source that says breast cancer is the #1 most prevalent CA in women? because BRS and robbins both say that lung is #1, breast is #2. first aid agrees with Qbank. can anyone clarify please??
