Introduction (3)

According to literature data.

Cancer incidence among rural population is lower than in general one

Cancer mortality in rural population is higher than in general one

Some neoplasms, such us prostate, ovaries cancers, melanoma are more frequent in rural than in general population

Positive relationship was found between pesticide use and leukemia, Hodgkin disease, multiple myeloma, melanoma, bladder, lung, colon, rectal, prostate cancers.

Introduction (4)

There are no data concerning to cancer prevalence and structural pattern in rural population of Armenia, as well as in population of Ararat valley

Many questions concerning to pesticides aren’t yet clear, their usage influence isn’t observed taking into consideration that Armenia has unique developed agriculture and wide assortment of pesticides being used.

Introduction (5)

The aim of our research was to study peculiarities of incidences and structural pattern of cancer

in rural population of Ararat valley.

Methods and materials (1)

Ararat region – teritory- 4.2% population- 8.8% agriculture- 6.5%

Armavir region – teritory- 7% population- 6% agriculture- 17%

Methods and materials (2) Research design - quantitative survey All cases of cancer registered in National

Institute of Oncology during 2011 and 2012 were included in study.

Data on population size taken from National Statistical Service of Armenia.

The total number of all cases was 2395:1099 in 20111296 in 2012.
