Orb on photos...need to clean inside?

I have read dust on the lens shouldn't be visible on images, but I have an orb that shows up in the same place on many photos. (It's not a ghost, though I bet the Stanley Hotel wold have been thrilled to see my pics.)

I can see a white spot on lens in the lower right edge of the inner circle (lens?) that is visible on the image I attached. (There are many white spots when I take a photo of the lens, but these aren't readily visible when I just examine it with my eyes.)

Is this something I can fix by taking it apart?

Do you think this is dust?

And where do you think the dust or whatever is? (Lens, sensor, or ...? Could be helpful in searching for a solution.)

Do you know of a link to instructions on how I go about fixing this issue?

THANKS!

I actually don't know what a cam frame is, but yes, the one I see with my naked eye is the red circled one. IF lenses work by flipping the image both horizontal and vertical, that would be the one right where the orb is on the photo. However, I also see a spot in the photo of the lens that has a spot just about exactly where the orb is now...
