If I Have Breast Implants, Can I Work Effectively As a Police Officer?

There is no reason why a reasonably sized breast implants would interfere with your ability to perform functions of a police officer. That's unless you find a surgeon who gives you excessively disproportionate, large implants.
The surgery itself is safe and common, your recovery should allow you to be physically active a few weeks after surgery.
Sincerely,

I have done breast augmentation procedures on people with physically demanding occupations and they have not had any problems related to the breast implants.
