Best answer: Can a person with Down syndrome get cancer?

Can Down syndrome get cancer?

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it’s been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Does Down syndrome increase cancer risk?

Down syndrome (trisomy 21): Children with Down syndrome have an extra (third) copy of chromosome 21. They are many times more likely to develop either acute lymphocytic leukemia (ALL) or acute myeloid leukemia (AML) than are other children, with an overall risk of about 2% to 3%.
