Prostate-Specific Antigen Author: Devon Carney
Example of an ultrasound impacted by prostate trouble. Cancer develops from the tissues of the prostate, a gland in the male reproductive system when cells will mutate to spread so uncontrollably.
These can spread ( metastasize is ) in migrating from the prostate to other parts of the body ( particularly bones and lymph nodes ).

Prostate cancer happens with no regard for benign prostatic hypertrophy ( or prostate adenoma ).
Prostate problems can cause agony, difficulty urinating, penile dysfunction and other symptoms. Treatment is by surgery, radiotherapy, hormone treatment and sometimes chemotherapy, or combination of these strategies.
The rate of breast cancer varies widely internationally. It is less widespread in South Far East and Far East, commoner in Europe and even the united states.
This is the type of cancer most typical in men, where he is responsible for more deaths than any other cancer ( except lung cancer ). However many men who develop prostate cancer symptoms do not, do not undergo any therapy and die for other reasons. Many factors of genetic origin, toxicological and diet-related appear involved in the development of this cancer.
In 3% of cases, this cancer will be lethal.
There are serious differences in the expression of this cancer, which appears commoner among the black man, or where the family has a history pathological with this condition. From 1983-2002, while deaths from cancer were generally higher in the Caribbean city, deaths from prostate trouble and stomach were twice as often found in the Caribbean in the mainland ( while colorectal cancer and lung cancer were three times less frequent ). is not ).
The causes are not known with precision.
There is a genetic predisposition and the presence of certain genes seems slightly interrelated with the commencement of the disease.
Nutritional causes were debated with a probably protecting role of lycopene. In a similar fashion, exercise may have a barely protecting effect and tobacco a deleterious effect.
Usually, prostate trouble is asymptomatic, ie it is discovered when it does not own event to it. It is most frequently found :
During blood tests, including investigation of the PSA ( express antigen for prostate, whose predictive price and use, without proved benefit to public health, has just been questioned ). This property has raised many hopes vis screening. The blood level of PSA can be increased by lots of other factors ( the prostate volume, infections and / or swelling, the mechanical ( digital anal other ) … ) or reduced by certain treatments for benign hypertrophy ( ministered ). The thresholds of significance therefore are tricky to establish. It is recognized rates of PSA between four and ten ng / ml are doubtful, but it is obviously major beyond. Some authors have proposed to bring the rate to its precise weight of the prostate, or appraise the free PSA / total PSA, or the kinetic growth rate over 2 years. Scorer still doubtful for screening, the PSA level is, however a key indicator for monitoring and treatment of cancers reported. .
