does cancer spread through generations?

[puuuke]

my mum had cancer when i was very young, then went 4 or 5 years cancer free before dieing of breast cancer when i was around 7.

im worried that i will get cancer, but i am unsure if it is possible for it to go through generations.

anyone know?

Cancer can be passed down through the family.
When my cancer popped up, I was questioned as to if any of my family has ever had brain cancer.
My cancer was not passed down to me, but breast cancer particularly I know can be passed down from parent to child.
Just be vigilant in getting your mammograms when you're supposed to, and doing self-checks.
Organizations such as Keep-A-Breast give instructions as to how to do these self-checks correctly.
If you notice anything weird, report it to a doctor, and you could stop the cancer before it's too out of control to stop.
