They call on behalf of Cancer Charities for a donation, [***] on those scumbags.

They called for a donation. How do these folks get our numbers.

If you donate to one charity, they soon share your contact information with other charities.

As Slim said, donating to one puts your name on a "sucker list", and before you know it, you'll be getting calls from charities you never knew existed--all shady ones at that. When I was taking unknown calls, I was hit by ridiculous ones like Disabled Firefighter, Police, Sheriff, drunk driving, and mentally impaired to name a few.
