How prevalent is acute lymphocytic leukemia in the U.S.?
There are about 6,500 new cases each year.
About 60% of those happen in children, and 40% occur in adults.
It is considered a bimodal cancer.
What that means is it happens in two different age ranges.
So it's the most common childhood cancer.
Then we see a little bit of a decrease in middle age.
And as we get over the age of 50, we see another peak of ALL.
In general, the average person's risk is about one in a thousand of developing ALL.
