Your friend have answered correctly,

1. All the diseases do not spread by physical contact. Only infectious diseases like common cold, smallpox etc spread through contact.

2. The non infectious diseases like cancer, high blood pressure, do not spread from one person to other.

3. The causes of non infectious diseases may lack of nutrition, genetic problems, accidents etc.
