What is prostate cancer?
Prostate cancer is a malignant tumor of the male prostate gland (prostate). Medically, prostate cancer is also called prostate carcinoma. In almost 70% of men, the growth forms in the outer zones of the prostate, far away from the urethra. The cancer of the prostate remains
Often undetected for a long time, because it causes little or no symptoms at the beginning. Only when the tumor grows does it become noticeable, for example through problems with urination. Prostate cancer: when. How often it occurs?Prostate cancer is the most common cancer in men in Germany. According to the guideline of the German Cancer Society one in six men over the age of 50 will develop the disease At. The Center for Cancer Registry Data gives a good 62 for the year 2017.200 new cases of.
Over nearly two decades, the incidence of prostate cancer has increased, probably because of improved early detection and the use of the PSA test. Above all, more prostate carcinomas were discovered in early stages. Without PSA testing, the disease might have gone unnoticed. Since 2011, however, the numbers are actually declining. In the future, experts reckon. Experts, however, again with more prostate cancer cases. Because by the year 2050, the proportion of men over 60 in the population is expected to rise to around 28 million – twice as high as it is today.
This demographic trend, with more and more older men, means that there are likely to be more new and existing cases of the disease in the population. Prostate cancer and age are very likely to be closely related: Before the age of 50. Prostate cancer is rare before the age of 50. On average, men developed the disease at around 72 years of age in 2017, reports the new S3 guideline on prostate cancer.
What is the prostate? The prostate gland – or prostate – is similar in shape to the. Size of a walnut or horse chestnut. It is a sex gland, so it belongs to the male reproductive organs. It is located in the upper part of the urethra. Its two lobes surround the urethra from the left and right sides. Above the prostate is the urinary bladder, behind it borders the rectum and below it the pubic bone. Many nerve cords, seminal vesicles and blood vessels also run in the immediate vicinity. There are five different prostate zones:
Peripheral zone: with almost 75 percent, the largest part of the prostate gland, is located below, to the side and behind – through a palpation examination via the rectum (digital-rectal examination), the prostate can therefore be felt.
Central zone: Makes up a quarter, includes the areas around the squirt ducts that carry the bulk of ejaculate.
Transition zone: this part becomes larger in the course of life, possibly up to benign prostate enlargement, is located in front of and to the side of the beginning of the urethra.
Urethral environment: this area consists mainly of muscle.
Anterior zone: In this thin area there is almost only connective tie and musculature, hardly any glands.
The glandular cells are also located within the connective tie capsule that surrounds the prostate. There are around 30 to 50 individual glands which, from puberty onwards, secrete a milky, cloudy, thin secretion under the influence of the male sex hormone testosterone. This secretion does not pass into the bloodstream, which is why the prostate is considered an externally secreting (exocrine) gland. In adult men, the prostate muscles contract during orgasm. Then a larger quantity of the secretion empties into the urethra, which forms the ejaculate from it – together with the sperm cells produced in the testicle.
The prostate gland weighs about 20 grams in a man around 20 years of age. With age, it can grow to a weight of up to 100 grams. In many men, a prostate gland develops in the second half of life Benign prostate enlargement (benign prostatic hyperplasia/BPH). It is usually harmless. Treatment is only necessary if the prostate gland grows too large, causing a man to have problems urinating.
It is different with prostate cancer. In this case, early diagnosis and treatment are crucial for the prognosis and chances of recovery.
