For smokers with certain symptoms

Lung Cancer (Part 2):
Frequency, causes, risk factors

cigarette smoke

The risk increases depending on the number of cigarettes smoked per day up to 20-30 times that of a nonsmoker. The risk increases also corresponding to the time period in which a person smokes in his live. Approximately one in ten smokers gets lung cancer in the course of his life, on average 30-40 years after the start of smoking. Even passive smoking is increasing the personal risk slightly (1.3-fold to 1.4-fold).

passive smoking

Cigarette smoke is the major cause of 80-90% of lung cancers in men and 30% -60% in women. The above-mentioned increase in the number of affected women is associated with increasing cigarette consumption. For pipe smokers and cigar smokers the risk of lung cancer is slightly lower than for cigarette smokers, but still extremely high compared to that of a nonsmoker.

In the workplace, various substances can be inhaled, which are carcinogenic, especially in combination with smoking.

arsenic

Some important examples which may be mentioned are: asbestos, arsenic, chromium, nickel, aromatic hydrocarbons and radon.

A high pollution of the outside air can increase the risk of lung cancer slightly (1.5 times). As a significant factor in this case the diesel is classified.

Diet also plays a role.

Vegetables and fruit

A too low consumption of fruits and vegetables increases the disease risk by 2x, especially in smokers. Artificial vitamins do not replace fruits and vegetables.
