I. Definition

Prostate cancer is a malignant disease of the prostate which is part of the male genital system. Amongst men, prostate cancer is one of the most frequently detected malignant diseases.
In Europe, there are 214 prostate cancer cases per 1000 males, making it more common now than both lung and colorectal tumours.
It is noticeable that evidence of prostate cancer is often found in patients who died as a result of other cancers.
The frequency of mutation increases exponentially with age.
Therefore, in developed countries, the health significance of prostate cancer increases with the average age of the population.
Currently, in developed countries, the rate of prostate cancer amongst male malignant diseases is 15%, while in developing countries it is only 4%.
Important findings have revealed that there are big differences in the prevalence of prostate cancer according to geographical regions.

Symptoms

It causes extremely diverse signs and symptoms. Initially, it is mostly urinary problems that present themselves. They are very similar to the benign enlarged prostate’s symptoms (frequent urination, urgent need to urinate or difficult urination). As the disease advances, signs normally associated with other kinds of tumours begin to appear.
Finally, urinating blood and/or urinary retention often occurs. The onset of metastasis makes the variety of symptoms even larger.
