You can always use your marque tool to make your selection,
Select>Inverse and delete. It will make the rest of the image go
away and will leave you with a transparent background. Then you can
Fit Canvas, or whatever you need to with the image.
Drag out an oval, fill it with white and position it over the
area you want
to save. I always reduce the opacity of the white oval/circle
so I can see
exactly where I'm placing it, but you must increase it back
up to 100% after
you're happy with the positioning. Select both your image and
the white oval
layer and Modify>Mask>Group as Mask. That should leave
you with only the
oval area visible. Now just Ctrl+Alt+T to trim the excess
