Uncontrolled factors for benign prostatic hyperplasia development.
1) Age
Risk for development of adenoma and prostate cancer increases with age. Someone with “black humor” said that each male who lives a longer life gets diseased with prostate adenoma. Prostate cancer in older men occurs frequently too. Around 70% of men with diagnosis “prostate cancer” are over 65.
2) Ethnic group
Studies show that people with black skin are more prone to prostate diseases than representatives of other races. Moreover, black people get diseased with prostate cancer in younger age and often have its severe forms. However, representatives of yellow race rarely get diseased with prostate cancer. Representatives of Middle East Semitic group (ethnic Arabs and ethnic Jews) show the same incidence frequency as representatives of white race of Central European origin.
3) Family history
Family medical history do influence on probability of prostate adenoma appearing. Among men aged 40 - 55 with benign prostatic hyperplasia, most had inherited gene which made them predisposed to the disease. However, the gene does not make the disease inevitable, but it increases risks for it.
4) Mass of bones
Mass ratio of bone tissue also may influence on risks for prostate cancer. Intensive studies that lasted 30 years showed that in men with bigger mass ratio of bones prostate cancer occurs more frequently. However, it is not known yet the causes of this correlation.
