I found 2012 statistics at the American Cancer Society's website.

How Many Cancer Survivors Are Alive in the US?
An estimated 13.7 million Americans with a history of cancer
were alive on January 1, 2012. This estimate does not include
carcinoma in situ (non-invasive cancer) of any site except uri
-
nary bladder, and does not include basal cell and squamous cell
skin cancers. The 10 most common cancer sites represented
among survivors are shown in Figure 1. The three most common
cancers among male survivors are prostate (43%), colon and rec
-
tum (9%), and melanoma (7%). Among female survivors, the
most common cancers are breast (41%), uterine corpus (8%), and
colon and rectum (8%).
