Understanding prostate cancer The prostate is the largest accessory gland in men and is an organ that only men have because it is arranged in front of the bladder like a guard, so people named it the “prostate”. The prostate gland is located between the root of the penis and the bladder and surrounds the posterior urethra. Although the normal prostate is only the size of a chestnut, its role in the human body is not to be underestimated. It can secrete prostate fluid, an important component of the toast, maintain the normal function of sperm, and is very important for fertility. It is precisely this bullet point of “mutiny” – prostate cancer – that has become the “number one killer” of older men. In our country, prostate cancer is on the rise. The number of prostate cancer cases in the last two years is nearly three times the number in the early 1990s, as observed in the clinical work of some hospitals. This is enough to raise public awareness of this disease. The difference between prostate cancer and other malignant tumors is that prostate cancer is also a cancer, but it is very different from other cancers. It has several special “personalities”, which are summarized in three words: “lazy, greedy and stubborn”. ”The first time some cancer cells appear in the prostate, the size of the tumor is small and it is often in a stable state, not posing a threat to health. There are no clinical symptoms. Prostate cancer is a “gluttonous” child, during most of its development, it only “loves” one thing, androgen, once androgen is blocked, it is like prostate cancer is cut off. ”The “stubborn” means that although prostate cancer is highly androgen-dependent, when hormone therapy is administered, the tumor cells will adapt to the new environment and slowly change to one that does not depend on sex hormones. The tumor cells will adapt to the new environment and slowly transform into tumors that do not depend on sex hormones. Once prostate cancer reaches this stage, it is very difficult to control its growth with current medical technology. This is the reason why prostate cancer patients should firmly grasp the time of treatment surgery, timely follow-up and treatment, otherwise the prostate gland will sooner or later enter the state of this “persistent disease” until the life of the patient is at stake.
