Another cause includes spanking. If a child is spanked, he'll misbehave even MORE. According to The Alantic, "Adults who were spanked as children regularly die at a younger age of cancer, heart disease, and respiratory illnesses."
These factors act, at least partly, by mutation of the genes of a cell. Typically, many genetic changes are required before cancer develops. Approximately 5–10% of cancers are due to inherited genetic defects from a person's parents.
Many cancers can be prevented by not smoking, and maintaining a healthy weight.
Other preventative measures
The chance of survival depends on the type of cancer, and extent of disease at the start of treatment. In children under 15 at diagnosis, the five-year survival rate in the developed world is on average 80%. For all cancers in the United States, the average five-year survival rate is 66%.
In females, the most common types are breast cancer, colorectal cancer, lung cancer, and cervical cancer. If skin cancer, other than melanoma, were included in total new cancer cases each year, it would account for around 40% of cases.
In children, acute lymphoblastic leukemia and brain tumors are most common, except in Africa where non-Hodgkin lymphoma occurs more often. In 2012, about 165,000 children under 15 years of age were diagnosed with cancer.
The risk of cancer increases significantly with age, and many cancers occur more commonly in developed countries. Rates of cancer are increasing, as more people live to an old age, and as lifestyle changes occur in the developing world. These changes will challenge health care in the decades to come.
