Something in my lens?

I hope I'm in the right section.

I bought my Canon PowerShot SD1300IS on Amazon last year, brand new.

I have never had this problem, I have plenty of pictures that I've taken that were fine.

I have let my mother use it and it's been rattling around in her purse for awhile. One day I asked her for it and went to use it for a concert I went to, and I noticed a big black dot in every single one of my shots. The dot got bigger and blurrier as I zoomed in.

I tried cleaning off the lens with a glasses cloth that I have, but I'm almost positive that whatever it is, is on the inside somehow.

I'm not sure where to bring it to get cleaned out, or if such a place even exists.. But I was hoping that someone else has had this problem before and could help me fix it so that I don't have to go out and buy a new camera for my trip in April.

Thanks in advance!

Looking at the front of the lens, can you see the spot?
Tap the camera against your hand to see if the spot will move.
Try using a vacuum cleaner to suck out the dust from the side of the lens opening, just don't cover up the whole lens with the vacuum.
