Each year the journal CA, A Cancer Journal for Clinicians, provides an analysis of cancer statistics for all cancers. Breast cancer continues to be the most frequently diagnosed cancer and the leading cause of cancer death among women worldwide. This initial report shows that the cancer burden continues to increase worldwide, attributable in part to the fact that people now live longer than in past generations.
In the US, cancer incidence has been stable for men and has been declining in women by 0.6% yearly since 1998.
In the United States for 2011, breast cancer accounts for about 30% of diagnosed cases and 15% of cancer deaths. Pennsylvania has one of the highest rates for both incidence and death from breast cancer in the US.
A follow-up report, issued later in the year, details statistics for the United States. For the complete US report, go to: http://onlinelibrary.wiley.com/doi/10.3322/caac.20121/pdf
