What I make of it is this:

This is a chest CT scan, a 3-d x-ray.  Similar scans of the rest of the
torso were done at the same time but not reported here.  The writer is asked
to ignore the cancer sites known from other tests.  This is the first time
this type of scan has been done on this patient, therefore there is no way
of assessing whether things are new or long established, growing or stable.
The scan shows a couple of suspicious spots on the right lung which are not
necessarily cancerous.  The rest of the scanned organs appear normal.  The
writer recommends that a further scan be done in 3 months to establish
whether these lumps are growing.  He also comments on an object visible near
the right armpit which he believes is not real but was spuriously generated
by noise in the imaging system.

I would think that the fact that the spots are on the same side as the
cancer and there are no spots on the other side, might mean a little more
cause for concern than there would otherwise be.

Understand that I am not a medical professional and could easily have missed
something.

You should not need to be asking this question.  Your consultant should not
give you this information without an explanation in layman's language.  It
is bad practice to give patients 'raw' technical reports as they are mostly
meaningless and often frightening to one who does not understand the jargon,
especially routine descriptions of things that are normal or unexceptional.
