From year to year cancer takes the lives of thousands, even of millions people all over the world.
It ranks second among the most common causes of premature deaths, giving the pas only to the cardiovascular diseases.
All normal cells in human’s body have determined duration of life. When the time is over, cells die off and get substituted by other cells.
Cancerous cells tend to grow and multiply out of control. They don’t die, propagating and crowding normal cells with time.
These cells may look like normal ones or may have different structure.
If these abnormal formations grow slowly and don’t spread to other body areas, the condition is usually called benign tumor.
At the same time malignant cells have ability to metastasize (propagate to other organs and tissues).
This trouble can occur in any part of the body, including blood.
Up to the present time it’s not completely clear, why do actually cancer develops.
Experts have found that aging, ethnicity and genetics play a great role in this disorder.
In addition to this, several potentially modifiable factors can extremely boost your hazards of malignancy. The most common of them include smoking, excessive weight, alcohol misuse, frequent exposure to radiation and lack of physical activity.
