ADC wire is picking up noise from cellular antenna [EMC]

Question

I have a 5 wire micro jst cable with a line for ADC readings from an IR sensor that is picking up interference from the cellular antenna of the microcontroller. Will I be able to reduce this noise if I use a USB cable with grounded shielding? What is the best way I can reduce this interference noise?

Thank you!
