One of the most well known risk factors for causing smoking is tobacco. The risk from cigarette smoking comes from two places:
direct smoking and second hand smoking. Direct smoking is the cause of about 87% of lung cancer deaths and also contributes to
the development of cancers in other parts of the body like the stomach, liver, kidneys and some kinds of leukemia. There are
some groups that promote non-smoking and it has been shown they have lower rates of lung cancer.
Secondhand smoking comes from smoke that is exhaled or from burning tobacco. When nonsmokers are exposed to this smoke that
causes them to absorb nicotine, it is called passive smoking. From passive smoking, an individual is inhaling 60 known
compounds that cause cancer.
You can also develop cancer from the sun and ultraviolet rays. UVA rays can cause skin cancer to form and UVB rays can damage DNA cells that will then lead to the development of skin cancer. You also have an increased risk of developing skin cancer from other sources of ultraviolet light such as tanning booths and sunlamps.
There are some substances known as carcinogens that cause changes in the body which then leads to the development of cancer. Some of the known carcinogens are asbestos, nickel compounds, arsenic, benzene and solar radiation.
Although these are factors that increase your risk of cancer, there are some steps you can take to reduce your risk of developing the disease. These include eating healthy and maintaining a nutritional diet by limiting your consumption of fried foods, alcohol, and refined carbohydrates. It is also in your interest to choose white meat over red meat and to eat whole grain foods rather than processed ones. It also helps to be physically fit by exercising at least an hour a day and walking as much as you can or joining a team.
