Read levistud's entry about luncheon meat and
Got myself really curious about cancer and the main causes of cancer.

Some Facts on Cancer (based on Wikipedia)

In the USA and other developed countries, cancer is presently responsible for about 25% of all deaths.

For males in USA, most common cancer is
prostate cancer (33%),
lung cancer (13%) and
colorectal cancer (10%)

For males in USA, most common cause of death is
lung cancer (31%),
prostate cancer (10%) and
clorectal cancer (10%)

The most consistent finding, over decades of research, is the strong association between tobacco use and cancers.

Lifestyle choices cause cancer: tobacco, diet, exercise, alcohol,tanning choices, and certain sexually transmitted diseases are the major risks.

There is also a growing body of research that correlates cancer incidence with the lower levels of melatonin produced in the body when people spend more time in bright-light conditions, as happens typically in the well-lit night time environments of the more developed countries. This effect is compounded in people who sleep fewer hours and in people who work at night, two groups that are known to have higher cancer rates.

Sodium Nitrite as a food addictive
As a food addctive, it serves a dual purpose in the food industry since
It both alters the colour of preserved fish and meats and also prevents
Growth of Clostridium botulinum, the bacteria that causes botulism.
While the chemical will prevent the growth of bacteria, it is also toxic for mammals.

Various dangers of using this food addictive have been suggested and researched
By scientists. A primary concern is the formatoin of carcinogenic N-nitrosamines by reaction with sodium nitrite.
