What are the different ways to repair concrete cancer?

What are the different ways to repair concrete cancer? Are there options like polymer-modified repairs or electrochemical treatments besides the traditional method of removing and replacing damaged concrete?

It depends where the concrete cancer or spalling is appearing.

It really depends on where the concrete cancer or spalling is appearing. Cracks can be injected with epoxy for structural issues or polyurethane for waterproofing. It is still better to treat the cause of the issue by re-waterproofing it above the crack.

If the issue is spalling, the most common repair method is to grind out the affected concrete, treat the corroded reinforcement and rebuild using a specific mortar.
