Is cancer contagious

Is cancer contagious?

Cancer is NOT contagious.

A healthy person cannot “get” cancer from somebody who has it. There is no sign that close contact or things like sex, kissing, touching, sharing food, or breathing the same air can spread cancer from one person to another.

Cancer cells from one person generally cannot live in the body of an additional healthy person. The immune system of a healthy person recognizes foreign cells and destroys them, including cancer cells from another person.

Germs are contagious

We know that germs (especially bacteria and viruses) can be passed from one person to another through sex, kissing, touch, and sharing or preparing food. Some can even be spread by breathing the same air. But germs are much more probable to be a threat to a person with cancer than to a healthy person. This is because people with cancer often have weakened immune systems, especially when they are receiving treatment. They may not be able to fight infections very well.

Is there any type of cancer that is contagious?

In general, no. Cancer is not a contagious disease that spreads easily from person to person. The only condition in which cancer can spread from one person to additional is in the case of organ or tissue transplantation.
