A disease that doesn't spread from person to person is called a noninfectious disease. And example is:
Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control, but in the case of cancer, these systems fail. Cancer is usually caused by mutations; you know that mutations are random errors in genes.
Cancer is caused by many different chemical substances. Dozens of chemicals in tobacco smoke, including nicotine, have shown to cause cancer. Smoking increase the rick of cancer of the lung, mouth, throat and bladder.
Another noninfectious disease is diabetes. Diabetes happens when the pancreas cannot make enough insulin. In other words, from to much sweets.
And allergy is when the immune system attacks a harmless substance that enters the body from the outside. Common causes of allergies include: Mold, dust, dead skin and bee stings.
