ABSTRACT
Introduction:
The monitoring of the lung malignant neoplasms incidence provides reliable data (particularly to medical and administrative services) in order that they could work out and undertake current and a long-term decisions concerning with organisation of fight against cancer (including costs of cancer treatment, investments in oncology, anticancer education, etc.). But existing need most rationally resolves in a struggle with lung cancer (and other cancer). Therefore an attempts looking for the endemic areas with a long-lasting appear the biggest and smallest lung cancer incidence rates in the Silesia population. It is aim of this work.

Material and Methods:
The monitoring of the malignant neoplasm ills, among others of the lung cancer, is based on obligatory procedure of reporting them on a form MZN1a (from 1962 year). After verifications used in this work – 27 796 cases total for males and females suffering for the lung cancer within Silesia voivodeship in the years 1999-2009. Age-specific (for 5-year age groups), crude and age-standardized rates (with the use direct method by M. Spiegelman) and with the use of the age-structure of “world population” (by R. Doll) – were calculated. Comparisons of rate values (between endemic areas) made of the use O.S. Miettinen and P. Katz procedures.

Results:
Silesia voivodeship it is the region of high risk lung cancer incidence in comparison to other ones in Poland. Lung cancer incidence among women is – in comparison to men – lower. But, just as among men – it is strongly differentiated according to counties. However, in comparison two periods – 1999-2002: 2006-2009 – standardized incidence rates among females have been increasing from 14.0/100 thousands to 15.6/100ths, i.e. about 11.5%, and among males have been decreasing distinctly: from 66.9/100ths to 53.6/100ths, i.e. about 20%. The biggest frequency of ill (statistically significant high) caused by the lung cancer among men concern following (an endemic areas with a biggest of menace) administrative units, i.e. counties: będziński, częstochowski, gliwicki, żywiecki and towns: Chorzów, Dąbrowa Górnicza, Gliwice, Jaworzno, Sosnowiec i Świętochłowice; similarly as for women: będziński (county) and towns: Bielsko-Biała, Chorzów, Dąbrowa Górnicza, Gliwice, Jastrzębie-Zdrój, Katowice and Sosnowiec: it is the biggest risk of incidence for lung cancer within them. There is a partial correlation (coherence) between endemic areas of the biggest lung cancer incidence rates, taking into account sex, i.e. males and females.

Conclusions:
1. There is a partial spatial correlation (coherence) between the endemic areas of highest and lowest incidence for lung cancer in the both sexes. 2. A more “aggressive” activities, especially concerning the primary preventive treatment care (i.e. overcoming nicotinism), could lead to decreasing the level of incidence caused by the lung cancer within high risk endemic areas.
