Is there any type of blood tests that can be given to detect if someone has some form of cancer growing in their bodies & cure it before its to late?

No: There are a couple of phony labs that offer this, one pair of well-intentioned people who offer a test that i would urge you not to rely on, and there is no substitute for a proper history and physical exam for cost-effective cancer screening. I'm more impressed with breast self-exam and colonoscopy as life-savers than anything else; tumor markers aren't realistic screens.
