GISTs occur in 10-20 per one million people. The true incidence might be higher, as novel laboratory methods are much more sensitive in diagnosing GISTs.

This makes GIST the most common form of sarcoma, which constitutes more than 70 types of cancer, but in all forms constitutes less than 1% of all cancer.
