Cancer Of Prostate – Treatments And Symptoms
Example of an ultrasound affected by prostate cancer (ultrasound can be used to guide a biopsy). Cancer develops from the prostate tissues, 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 (especially bones and lymph nodes).
Prostate cancer occurs regardless of benign prostatic hypertrophy (or prostate adenoma). It is in the vast majority of cases adenocarcinoma.
Prostate cancer may cause pain, difficulty urinating, erectile dysfunction and other symptoms. Treatment is by surgery, radiotherapy, hormone therapy and sometimes chemotherapy, or combination of these methods.
Frequency
The rate of breast cancer varies widely throughout the world. It is less widespread in South Asia and Far East, more common in Europe and even the United States. According to the American Cancer Society, breast cancer is rare among Asians as well as more prevalent among blacks (high rates may also be influenced by the increased effort detection).
ProstateProstate cancer develops most often in men over 50 years. This is the type of cancer most common in males, 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 some reasons. Many factors of genetic origin, toxicological as well as diet-related seem involved in the development of this cancer.
We find outbreaks of cancer cells in 30 to 70% of cases in studies performed in autopsies of men 70 to 80 years (details information is included in prostate cancer survival rates); prostate cancer remains the most often asymptomatic: the probability of a man 50 years know a diagnosis of prostate cancer is only 10%. In 3% of cases, this cancer will be fatal.
Geography of Prostate Cancer
There are significant differences in the expression of this cancer, which seems more common 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 cancer and stomach were twice as common in the Caribbean in the mainland (while colorectal cancer and lung cancer were three times less frequent). This could be explained by both genetic reasons and food (green tea and / or soybeans or other foods rich in selenium) which appear to protect most Japanese living in Japan (while living in the United States is not).
Causes
They are not known with precision.
There is a genetic predisposition and the presence of certain genes seems slightly correlated with the onset of the disease. In particular, a mutation on chromosome 8 might explain the higher incidence of this cancer in black American.
Nutritional causes were discussed with a potentially protective role of lycopene. Similarly, exercise may have a slightly protective effect and tobacco a deleterious effect.
