I’ve had a bump on my eyelid for over a week, is this cancer?

I’ve had a bump on my eyelid for over a week. At first I believed it was a cyst but it won’t subside and is larger. I don’t know what it is or how to deal with it, hopefully it isn’t as serious and will go away but please help me identify what this bump is, the cause and solution.
