How Fast Can Skin Cancer Spread And Grow? Does It Take Days, Weeks, Or Months?

I see all of these things that say… you need to catch skin cancer early. But nothing says what early means, does this mean every time i see an abnormal thing on my skin i should run to the doctor? Or should I wait a day, or a week, or a month?
When people go to the doctor and the cancer is in it’s late stages, were they an hour too late, a day too late, a week too late, 10 years to late?
Seriously… cancer sites need to put more information out there about rate of growth and timing.
