Is cancer contagious?

While some animal cancer was found to be contagious, no human form has been found so far. However, some contagious diseases can cause cancer in humans. These diseases do not pass cancer cells, but viruses causing diseases. In addition, some behavior is considered contagious, or at least may cause cancer -causing attractions. In this case, cancer cells are not contagious, but the behavior that causes it to be smoking can be more likely in family groups.

Some viruses are directly related to certain cancer. For example, some forms of human papillomavirus (HPV) are now referred to as the primary cause of all cervical cancer and can also cause penis cancer. There are only a few types of human papillomavirus that cause such diseases, and not anyone who has a virus will gain cancer. All HPV types that can cause them to be sexually transmitted.

Another sexually portable noThe power that is indicated in the form of cancer is the Human Herpes 8 (HHV8) virus. It was associated with the development of Kaposi sarcoma and is almost always incorrectly labeled as caused by AIDS. This misunderstanding occurs because people with HIV and AIDS are exposed to a much greater risk of HHV8.

Some behavior can predict people for certain types of cancer and disease. For example, those who smoke not only risk lung cancer, but can also increase the risk to others they smoke. Moreover, children of parents who smoke more often smoke. So in an unconventional sense, this behavior can be considered "contagious".

Alcoholism is another form of indirectly "contagious" behavior that increases the risk of stomach and liver cancer. Children of alcoholics become more often alcoholics. Although it may be in the part of Behavioral, there may also be genetic factors that predetermine people to addiction. In thesePads can move from one generation to another to increase the risk of certain form of cancer.

In the traditional sense "contagious", most forms of cancer cannot be handed over to another person. However, the recent discovery of the role of HPV in cervical cancer raises questions about whether others can be exposed to certain viruses or bacteria. Scientists continue to investigate this area in the hope of finding more ways to treat and prevent these diseases.
