You won't need to replace the cable.
Just cut out the bad section out, put proper connectors on the ends and make or buy a short jumper piece to connect in.
Yes, you will end up with two added connector sets but that small additional loss is nothing compared to the problems that can occur when you damage the shield.
Most people don't understand that coax cable at these frequencies acts as a waveguide. The shield is an integral part of the wave guide. Behaves very differently than a pair of wires for DC or AC power.
