Introduction:
An amount of the cancer deaths within Silesia Voivodeship is constantly increasing, although unequally in a separate districts. Therefore an attempt looking for endemic areas with long-lasting appear the biggest and smallest mortality rates.

Material and Methods:
On the basis of the „death cards” and the demographic data the main Bureau of statistics, the partial (for the 5-year age group: 0–4, 5–9, up till 85+) crude and standardized according to the age structure of the „world population”– cancer mortality rates were calculated. The calculations of the above mentioned rates were based on the 125,162 persons who died as the result of cancer in the years 1999– 2009 within Silesia Voivodeship.

Results:
It is assumed that in Silesia Voivodeship the registration of deaths by causes can be characterized by a high degree of completeness, what give objective and reliable statistics values. In the years 1999–2009 in Silesia Voivodeship 125,162 person died as the result of all cancers (70,544 males, i.e. 56,4% and 54,618 females i.e. 43,6%). Age-adjusted average mortality rates varied from minimum of 182.0/100 thousand to maximum 247.3/100 thousand among males and from 89.9/100 thousand to 135.4/100 thousand among females. The distribution of age-standardized cancer mortality rates for all sites among males and females within Silesia Voivodeship (by 36 counties) is very unequal. On the maps (fig. 1D and 2D) described the endemic areas with the biggest and smallest statistically significant mortality rates in the years 1999–2009.

Conclusions:
These results it is a base to organize of diverse prevention activities (anti-cancer education, secondary prevention – screenings, etc.).
