Wow a PSA that is actually a PSA.

I do not think that they are equivalent. Violence is easy to "grab" the face. When an 8-year-old child sees something like DOOM, they do not mimic it in real life. It is easy for an 8 year old child to understand that violence is wrong at the moment. If not, I think this is another question

On the other hand, to suggest sexuality, I think parents would want to sit with their children for the first time. Therefore, the exposure of children to such things should be controlled by parents, which is why I think that they are interested for why we filter it.

When it becomes violence, there is no equivalent to "bird and bee". The closest thing is to talk with the child after the child is playing at school or elsewhere.

PSA speed and PSA doubling time PSA speed is the rate of change of male PSA level over time and is expressed as annual ng / mL. The PSA doubling time is a period in which the male PSA level doubles. Several lines of evidence suggest that the rate of increase in male PSA levels may help predict whether he is suffering from prostate cancer. Pro-PSA pro PSA refers to several different inactive precursors of PSA. There is evidence that pre-PSA is strongly related to prostate cancer and BPH. A recently approved test combines the measurement of pro-PSA form called proPSA with the measurement of PSA and free PSA. The resulting "prostate health index" helps to determine if people with PSA levels between 4 and 10 ng / mL should undergo biopsy.

PSA is a specific protein produced by the prostate. The level of PSA varies with age, but most men with prostate cancer usually have PSA levels above 4 ng / ml. Unfortunately, 15% of men with prostate cancer have a PSA lower than this value. In my experience, PSA level trends are more important than absolute amounts. 1) The higher the age, the higher the PSA. If you examine the prostate glands of all men over the age of 80, you may find that everyone has signs of prostate cancer. The problem is that most people die from disease rather than disease. The real problem is that there are more positive people than the benign forms of prostate cancer. Many people think that PSA test should be stopped at the age of 70 and over.

There is no proportion of PSA. PSA has two main forms in the blood. One binds to or binds to blood proteins, and the other circulates freely. PSA-free percentage tests showed how much freedom PSA has compared to total PSA levels. The proportion of free PSA in prostate cancer patients is lower than in men without prostate cancer. If the PSA results are in the critical range (4 to 10), the lower proportion of PSA (less than 10%) means that there is a 50% chance of prostate cancer, probably a biopsy Is required. Some physicians recommend biopsies of men with no more than 20 PSA.

Total PSA is free. The amount of PSA in "free" (not bound to other proteins) divided by the total amount of PSA (free + bound) in blood is expressed as the ratio of free PSA. Several lines of evidence suggest that a lower percentage of free PSA may be associated with more aggressive cancers. PSA density in the transition zone The blood concentration of PSA is divided by the volume of the transition zone of the prostate. The transition zone is the inner part of the prostate surrounding the urethra. Several lines of evidence suggest that this measurement method may be more accurate than the standard PSA test in the detection of prostate cancer.
