In 2002, 70,651 men and 68,883 women were diagnosed with Colorectal Cancer. Among them, 28,471 men and 28,132 women died from this disease. Even more cases are diagnosed in Europe, with 190,000 new cases every year.

This disease strikes people in their middle age and increasingly thereafter. In fact, we find 92% of Colorectal Cancer cases occurring in people over 50.

Current statistics on Colorectal Cancer show an increase from 10 cases per 100,000 people at the age of 40 - 45 years, to 300 cases per 100,000 people at the age of 75 – 80 years.

The lifetime risk of developing this cancer is about 7 percent, in the US.

This cancer is much more frequent in the Western world than in Asia and Africa. However, immigrants to our country also have a higher incidence of Colorectal Cancer than those that stayed behind. Therefore, our high risk of Colorectal Cancer may be related to our different lifestyle, such as our sedentary life and Western dietary habits.

Fortunately it has been found that in animal experiments and in studies of humans that a Calcium-rich diet and Calcium supplements have a protective effect and will lower the risk of Colorectal Cancer. To this end, doctors recommended regular intake of Calcium supplements, as well as physical activity, a diet high in fruits and vegetables but low in fat and red meat, along with other measures.
