Prostate cancer is the male reproductive system common malignancy. Prostate below the bladder in a chestnut-shaped gland, in the middle through the urethra. It is the secretion of sperm liquid nutrient solution is a component of semen. Benign prostate enlargement and prostatitis produce similar symptoms and cancer. Prostate cancer mainly primary site for posterior subcapsular gland, was latent slow growth, a tumor hours without any clinical manifestation. Thus the advanced prostate cancer generally only show symptoms. A clinical disease duration and often asymptomatic B, C obstructive symptoms of a period, and D both distant metastasis obstructive symptoms have symptoms.

Etiology
The cause of prostate cancer etiology is not clear. But what is certain is prostate cancer and genetic factors, environmental factors and the level of a certain hormone relations.

Additionally, there are a variety of related factors, such as prostate had gonorrhea, and chlamydia virus infection, sexual activity and increase hormone levels change, age, high-fat, vasectomy resection, smoking, heavy metal contact, inappropriate sexual life and the STD.

The incidence of prostate cancer may be affected by many factors, emphasizing the significance of a single factor is very difficult.

Clinical manifestations
Early symptoms: difficulty urinating, was gradual, starting only urine fine line change, the future development impeded urination, urination and effort, not the final performance for the line drops of urine; Frequency, urgency, hematuria; Voiding pain or burning sensation; The lower back, pelvis or upper thighs of the row pain.

Advanced symptoms: bone marrow depression, tumor metastasis, vice tumor syndrome, with a high calcium, pain, high uric acid, pleural leakage, swelling of the legs.

Common symptoms of the following three groups:
(1) obstruction symptoms of prostate cancer of the bladder neck obstruction and symptoms of benign prostatic hyperplasia almost no difference in performance for urinary ease, urgency, urinary interruption, not urination, frequency, can cause serious drop Lek urination and urinary retention. The process of blocking its clinical significance 2:00: ① disease progresses, and prostate hyperplasia, the slow progress in different conditions; ② hematuria is uncommon. It is worth noting that prostate cancer is not the first symptoms of urethral obstruction, the more common it is the proliferation of regional or bone metastases only in advanced cancer organizations around the urethral gland violations caused obstruction symptoms.

(2) transfer of symptoms when the tumor capsule and the surrounding nerves of the peripheral lymphoid, there will be the perineal pain and sciatica. Bone pain is a common symptom D, waist and pelvis showed the continuing pain, more intense when bedridden; Rectal involvement performance can be difficult for defecation or colonic obstruction; Other transfers have symptoms of lower limb edema, swelling of lymph nodes, subcutaneous metastatic nodules, pathologic fracture.

(3) systemic symptoms of systemic symptoms as weight loss fatigue, low heat, anemia, cachexia or renal failure.

Laboratory tests
Elevated serum acid phosphatase and prostate cancer metastasis, but the lack of specificity. In recent years by radioimmunoassay can improve its specificity. Benign prostatic acid phosphatase monoclonal antibody, prostate antigen specificity of their needs to be raised. C stage prostate cancer 20% to 70% of the acid phosphatase increased, lymph node metastasis also increased, if sustained increase will certainly have bone metastasis. Serum acid phosphatase and prostate acid phosphatase increased after surgery in the fall, is a symbol of better prognosis. In coated with prostate cancer from benign prostatic acid phosphatase cells secreted by the prostate catheter drainage, prostate cancer, cancer cells without the acid phosphatase from ductal carcinoma lesions were ductal or obstruction of oral cycle, and acid phosphatase increased.

Treatment
Prostate cancer treatment, mainly surgical treatment, hormone therapy, chemotherapy, radiotherapy and immune therapy. The selection of the specific method, in accordance with the patient's age, general condition, cancer and the transfer of local circumstances.

(1) Surgical treatment:
1) prostate cancer radical operation, covering the prostate gland and prostate capsule;
2) removal of pelvic lymph nodes;
3) Transurethral resection of the prostate, bladder neck obstruction for lifting.

(2) Radiation Therapy: Radiation therapy of prostate cancer has more than 60 years of history, mainly in the following ways: a) in the radiotherapy; 2) the organization radiotherapy, and in this way often radical prostatectomy with or combined with pelvic lymphadenectomy; 3) systemic radiotherapy : to a certain extent, can alleviate the pain of bone metastasis and reducing disease development.

Prognosis
Prostate cancer development process varied considerably, the prognosis varies.
A1 period: the elderly do with distant metastasis to 8%, 2% in five to 10 years died.
A2 period: 30% distant metastasis, 20% in five to 10 years died of prostate cancer.
B1 period: 30% in the transfer of five years, 20% died of prostate cancer.
B2: 80% in May to 10 years in the transfer, 70% died of prostate cancer.
Stage C: 50% in five years distant metastases, 75% died of cancer in 10 years.
D1 period: 85% in five years distant metastasis, died of cancer three years the majority.
D2 period: 50% in three years died of prostate cancer, five years 80% 90% 10 years died of cancer.
Endocrine any recurrence after treatment, 90% of deaths in two years.

Diet therapy
Fish eat beans and vegetables, soy isoflavones can reduce the damage of male hormones, and restrain and kill cancer cells. Eat all kinds of vegetables. Chinese cabbage, cauliflower, the West has blue flowers and vegetables of the effectiveness of prostate cancer. Fish containing a body can prevent prostate cancer OMEGA-3 fatty acids, especially the more fat such as salmon in the fish contain more OMEGA-3 fatty acids, the fish were not regular prostate cancer susceptibility.

In addition, daily snack can also flaxseed, tomatoes. Tomatoes contain lycopene on prostate cancer prevention role.

Prevention and treatment of prostate disease recipes:
Breakfast: a glass of tomato juice;
Lunch: eat a bowl containing carrots, cabbage or blue flowers West salad or boiled vegetables;
Dinner: 1:00 to eat beans, rice or brown rice to eat; Hungry stomachs, a snack at radishes, tomatoes, neither obesity, and the prevention and treatment of prostate cancer benefit.

Should they drink green tea every day, with the timing and quantity of tea increased, the role of green tea on the performance of the more obvious. Prostate congestive easy to drink. Even if they can only drink alcohol in the lower drink some wine. More details on diet, can not only effectively prevent and treat prostate disease, the health of men in all aspects, are also very good.
