Part of being a good friend is being there for a friend that is sick. You may feel uncomfortable when you visit a sick friend and you may worry about saying the right thing. It is important to remember that this friend is the same person that he always was. If you feel uncomfortable about being with him, share your feelings and ask if there is anything you need to know. More often than not, your friend will want you to just be yourself and you will see that nothing has changed as a result of his illness.
