When a cable is deformed, either coax or twisted pair, an impedance bump is created that will affect the signal.
All taken into account when the protocol was designed. Otherwise all cat5e cables would be straight and ridged.
There's no use wringing your hands about this because cables will never stay straight or pristine. If you sincerely believe this will cause signal degradation, i sugges you get out your scope and try to measure it.

With fiber-optic cables there is a minimum radius of curvature. That was interesting to find out. The reason is light reflects off the side of the cable as it propagates down the fiber. It the bend is too great, the light going down the fiber won't reflect, but instead will go through the side. That I've heard of and its a real issue because it is easy to bend the fiber too tight. But for cat5, I'm not aware of any minimum bend radius issues that need to be consciously thought about when you install it.
