Change game-cursor on gameobjects within range

Hi.

I have a problem with the following code:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.EventSystems;
 
 public class Move : MonoBehaviour
 {
     public bool Cursor_enemy = false;
 
     public float radius = 50f;
     public  Collider[] colliders;
     public LayerMask mask;
 
     void LateUpdate() {
 
         Ray ray;
         RaycastHit hit;
         ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         colliders = Physics.OverlapSphere (transform.position, radius, mask);
 
         foreach (Collider col in colliders) {
             if (Physics.Raycast(ray, out hit)) {
                 if (hit.collider == col) {
                     Cursor_enemy = true;
                 } else if (hit.collider != col) {
                     Cursor_enemy = false;
                 }
             }
         }
 
         if (Cursor_enemy == true) {
             GameObject.Find ("Canvas").GetComponent<InGameCursor> ().enemy_target = true;
         } else {
             GameObject.Find ("Canvas").GetComponent<InGameCursor> ().enemy_target = false;
         }
     }

This code change the game-cursor when it's hovering the first gameobject in the array of colliders found within a radius of 50 units, but it doesn't change the game-cursor when it's hovering any other gameobject that's within 50 units also.

Am I using a wrong method here?
