Cancer is not transmitted in the same way as infectious diseases; it cannot be spread from person to person. However, certain risk factors can increase the likelihood of developing cancer, such as genetic predisposition, exposure to carcinogens (like tobacco smoke and UV radiation), and certain viral infections (like HPV or hepatitis B). Additionally, lifestyle factors such as diet, physical activity, and alcohol consumption can influence cancer risk.
There are multiple human pathogens that can be transmitted through blood. HIV is probably the most commonly known, but other important ones are hepatitis A, B and C (which can cause liver cancer).
The reason that cancer is an example of a non-communicable disease is that it can not be transmitted person to person. A cold is communicable because you can get a cold from someone else.
Tobacco is not trasmitted, other than by legal (or grey market) sales of cigarettes or other forms of Tobacco. This question appears to be posted by someone who wanted to answer it themselves to deter people from smoking.
Sometimes cancer is genetic, but it increases a person's odds when they are exposed to cancer causing agents. Cigarettes contain many chemicals that are known to cause cancer.
