Cancer Risk Increasing With Age

Postby Shattuck » Sat May 14, 2016 3:27 pm

What makes our risk of cancer increase with age?  Why are there relatively so few cases of cancer in younger people?

Is it a lowered immune system thing?

Cancer Risk Increasing With Age

Postby Buckley » Sat May 14, 2016 9:50 pm

Dear Lianne,

Great question! We don't know all the answers but a declining immune system is part of it.

But the biggest risk seems to be the accumulated damage of life. we now think that most or all cancers start in our stem cells. These are cells that last our whole life. As the accumulate damage from chemicals, radiation, or viruses, there is a risk that they will lose control of their growth and turn into a tumor.

Sincerely,

Michael
