If it's not one cancer...

Then it's another. As if getting successfully through one cancer diagnosis is not triumph enough, Danish investigators sorting through a half million records found that women who survived breast cancer had a 25% increased risk of contracting a new primary nonbreast cancer in 57 years of follow-up compared with women cancer-free from the outset.

The scientists suggested several reasons why this might be so including: a genetic susceptability to cancer, shared environmental risk factors, the result of previous cancer treatment, and increased surveillance.
