abstract: Physical activity has a particularly beneficial effect on the immune system, reduces the concentration of sex hormones, effectively struggling with obesity and improves digestion and accelerates intestinal transit by reducing the risk of cancer.
  
  
  OBJECTIVE
  The aim of study was to determine whether lead an active lifestyle during childhood and adolescence may protect against the onset of cancer, a statement whether the person who contracted actively participated in physical education classes and whether practiced sport they have completed school. Also analyzed the way leisure and determined whether children and young people devote sufficient time to the activity. They attempted to determine whether their BMI contributed to the occurrence of cancer.
  
  
  METHODS
  The study was conducted in the period from September to November 2014 and January 2015 Podkarpacki Oncology Center at the Provincial Specialist Hospital. Frederic Chopin in Rzeszow. The study included 100 patients with a diagnosis of various cancers. The average age of patients was 52.6 years. Among the respondents, 39 people lived in the countryside, and 61 in the city. Most subjects had secondary education (50% of respondents). The body mass index of 41% was normal, 38% were overweight and 17% obese.
  
  
  RESULTS
  It was found that abnormal BMI had no impact on the incidence of cancers among respondents. Respondents are asked about whether they were active in school age in the vast majority (92% respondents) answered yes. However, the active forms of leisure declared only 35% of respondents. A large group of respondents do not devoted enough time for extracurricular physical activity as much as 48% devoted for this purpose only 0-0,5 h week. In physical education classes actively participated 82% of respondents, while sport after graduation cultivated only 10% of respondents.
  
  
  CONCLUSIONS
  Although the current study did not confirm a statistically significant correlation between the activity of school age, and the incidence of the most common cancers can be seen that the activity was investigated in many cases insufficient. It should therefore promote the activity of making a beneficial effect not only in childhood, but also at any age. It is advisable to study on a larger group of patients.
