All the cancers begin within the basic unit of life – the cell. Normal cells during a body have the power to grow and divide during a controlled thanks to produce more cells as per needed to stay the body healthy. When the cells get older or damaged, they die and obtain replaced with new cells. During a normal process, old cells die after a particular period of your time and are replaced by new cells. But during a cancerous state, new cells keep it up developing while old cells don’t die once they should thus resulting in a mass of tissue referred to as a tumor in order to control it visit cancer hospitals.

There are certain risk factors which could cause cancer development. These are:
- Growing Older
- Certain chemicals and other substances
- Some viruses and bacteria
- Certain hormones
- Case history of cancer
- Poor diet, lack of physical activity, or being overweight
Most of those risk factors are often avoided, while some others, like case history, can’t be avoided. Wherever and whenever possible, steps are often taken in staying faraway from known risk factors.
