What is the real cause of cancer?

Exposure to certain factors in the environment, such as chemicals like asbestos and benzene, as well as talcum powder and various sources of radiation (including excessive X-rays), can also cause cancer. These substances capable of damaging DNA and triggering cancer are referred to as carcinogens.

There is no one single cause for cancer. Scientists believe that it is the interaction of many factors together that produces cancer. The factors involved may be genetic, environmental, or constitutional characteristics of the individual.

How does cancer cause death?

Cancer kills by growing into key organs, nerves, or blood vessels and interfering with and impairing their function. It can begin in almost any human cell. Usually, new cells form through growth and division. Cells die once they become too old or damaged, and newly formed cells replace them.

What causes childhood cancer and what causes adult cancer?

A sporadic (occurs by chance) cell change or mutation is usually what causes childhood cancer. In adults, the type of cell that becomes cancerous is usually an epithelial cell. Epithelial cells line the body cavity and cover the body surface. Cancer occurs from environmental exposures to these cells over time.

How are the cells in your body affected by cancer?

Cell changes and cancer. Our bodies are made up of more than a hundred million million (100,000,000,000,000) cells. Cancer starts with changes in one cell or a small group of cells. Usually, we have just the right number of each type of cell. This is because cells produce signals to control how much and how often the cells divide.

How does a virus cause a person to get cancer?

Possibly, the virus alters a cell in some way. That cell then reproduces an altered cell and, eventually, these alterations become a cancer cell that reproduces more cancer cells. Environmental exposures. Pesticides, fertilizers, and power lines have been researched for a direct link to childhood cancers.

Why are some people more likely to get cancer?

They can also be caused by the processes of life inside the cell. Or by things coming from outside the body, such as the chemicals in tobacco smoke. And some people can inherit faults in particular genes that make them more likely to develop a cancer. Some genes get damaged every day and cells are very good at repairing them.
