To better understand how this wall nut like gland is affecting men, one must know it's position. It is situated next to the urethra and the front part of the prostate actually surrounds this tube, used for carrying urine from the bladder. Therefor changes, even of the smallest matter in the shape of this gland lead to difficulty in urinating, because they narrow, sometimes even block the urethra.

After knowing the position of the prostate and it's effects on men, the next question would be: but what is prostate cancer and how it do men develop this? Of course I will also answer this question. First we must know that the uncontrolled growth of cells makes a lump or tumor in medical terms(and in our case a prostate tumor). This can be of two kinds : either cancerous, also known as malignant or benign, which doesn't cause cancer. There is also known that the most likely part of the prostrate to get cancerous is the outer one. Symptoms differ from one person to another. Some men never have any symptoms at all, opposite to others that have. The reason why that happens is related to the way in which the tumor grows. If it grows slowly, it may never become a serious thereat to one's health. But if the growing is aggressive or fast, the results can be very harmful.

Symptoms may appear when the urethra is narrowed by the growth of cancer in the prostate. Men may feel then various symptoms such as: urinating difficulties: a weak flow of urine, sometimes even intermittent, the need to eliminate urine very often, blood, a continuos felling of needing to urinate and pain when one orgasms. But these symptoms don't necessarily men that one has prostate cancer because they are similar to another tipe of disease, a non-cancerous one, when the prostate is enlarged. If found in time, prostate cancer can be cured. Be careful though because there is always the risk of cancer spreading to the bones, developing more symptoms: pain in the bones.

The second part of the question was: but why to men get cancer. Well this is a difficult one, for nobody knows for sure even to this day. Certain factors that make this type of cancer more likely are: age(the risk of developing prostate cancer rises with age), the origin may also be a factor, a diet full of fats can increase the risk of cancer and nevertheless genetics(one may inherit the cancerous gene).

If symptoms similar to those above appear, is best that you see a doctor. By the advanced tehnology offered to us today combined with old mhetods, a doctor can easily diagnose you. The first thing to do is feel your prostate, to see if it is hardened or knobbly. To do that, the doctor gives you a rectal examination, inserting his finger into your rectum. Another method is a blood test. This reveals the level os prostate-specific antigen. If the number is very big, this may indicate a prostate cancer. It can also indicate other disease of the prostate, therefor it is not a certain method. A third one and more secure is the biopsy. A small part of the prostate is taken with the help of a needle and sent for further investigation.

If indeed one is diagnosed with prostate cancer, there are more methods for doctors to find out how far the cancer has spread. A magnetic resonance imaging(MRI), a tomography or bone scans.
