Senator Claire McCaskill says she has been diagnosed with breast cancer.  In a blog post, the Missouri Democrat explained that the cancer was detected through a regular mammogram. 

She'll be undergoing treatment for the next three weeks in St. Louis.  She says the prognosis is good and she expects to make a full recovery. McCaskill has been representing Missouri in the Senate since 2007 and is 62 years old.
