The causes of prostate cancer

prostate cancer called malignant neoplasm arising from the alveolar epithelial cell glands.
common malignant process is denoted by four degrees of prostate cancer:
first stage, usually microscopic, and can not be detected during a digital rectal exam or ultrasound;
second step is a malignant tumor that has not spread beyond the prostate gland;
On the 3rd stage of the tumor begins to spread to nearby tissue (seminal vesicles);
On 4th stage of the tumor extends beyond the body and goes to other tissues.

Cancer BPH, who is in the early stages, are not able to metastasize.At this stage, the area of ​​distribution is limited to the prostate.If the cancer is progressing, ieis 3-4 stages of the process, it is possible that will metastasize to the lungs, lymph nodes, liver and bone.

Symptoms of prostate cancer

the initial stages of cancer symptoms of BPH are similar to the symptoms of benign prostatic hyperplasia.The patient may be a part of going to the toilet on the little night-time urination can be
difficult.Then, as the tumor spreads, the disease is characterized by pain, occurring in the abdomen, in the urine appear traces of blood.The patient noted a general weakness, fatigue and weight loss.If prostate cancer is launched, and metastases have pronounced, it can manifest occurrence of bone pain, swollen lymph nodes, jaundice.
Diagnosis of the disease in the early stages of malignant process difficult.Confident diagnosis of the presence of cancer of the prostate can be made if visibly tight formation, roughness and increased the size of the prostate.Only 10% of prostate cancer that is detected during digital examination, amenable to effective treatment.Set prostate cancer at an early stage by using the needle biopsy of the prostate, and ultrasound imaging.

The causes of prostate cancer

all causes can be conditionally divided into 3 groups.The first group includes the risk factors identified by the study.The main risk factor is age.Cancer BPH occurs in about 70% of men over the age of 80 years.The likelihood that prostate cancer is detected in 39 are over the men is 1 in 10,000, are over the 59 - 1 to 103 men between the ages of 60 years - 1 to 8.
causes of prostate cancer are alsomay be hiding in the hereditary, genetic level.This factor accounts for 10% of the total number of cases of prostate cancer.
The second group of reasons are likely risk factors, or by the study, but not all.The probability of the disease increases with the consumption of large amounts of animal fats.These products are fast foods, chips, burgers, salty foods, meats, dairy products, fried foods, fatty fish, fat meat.
The third group of causes of prostate cancer are potential risk factors that have not been proven in research, but there is speculation that they are important in the development of cancer of prostate adenoma.
also contributes to the development of prostate cancer low levels of vitamin D. The results showed that people living in the south, is much less likely to suffer from this disease.
also on the development of prostate cancer is influenced by reproductive tract infections (mycoplasma, pale treponema, gonococci, trichomonas, chlamydia).They cause in normal, healthy cells as irreversible changes as a starting point in the development of tumors.
of prostate cancer also occurs because of the hormone androgen, which in itself is not carcinogenic, but play a catalytic role in the development of the disease.
Most prostate cancer is at the stage of precancer, which is understood as a group of diseases characterized by changes in the epithelium of the prostate gland.In certain conditions of disease can go into prostate cancer.

to precancerous diseases include:
- intraepithelial neoplasia;
- atypical hyperplasia.
