Israeli Prime Minister Ehud Olmert in Jerusalem recently held a news conference to admit that he suffering from early stage prostate cancer. This once again sounded the alarm for us. Talking about prostate cancer, people often think it is Europe and the United States “patent”, because in Europe and the United States population, the incidence of the disease as much as 100/10 million more, the Habitat cancer was the second largest cause of death. The incidence of prostate cancer in China although much lower than western countries, but were significantly increased in recent years the trend.
According to statistics, every year there are about 80,000 prostate cancer new cases mainly occurred in over 60 years in the elderly. Because prostate position concealed, cancer site will occur after the leaves around the zone, not oppression urethral early urination difficulties caused symptoms, the incidence of early and mid-often without any symptoms, it is difficult to arouse the vigilance of patients; If any discomfort, such as urination difficulties, but also often mistaken for a year old performance, or prostatic hypertrophy induced, in turn delay early diagnosis and treatment.
■ prostate specific for the men, there are four reasons for Carcinogenesis
The prostate is a bladder at the bottom, wrapping around the urethra gland, such as chestnut normal size, from the middle through the urethra for men unique. It secretion of the liquid is a component of semen. Now that the incidence of prostate cancer with the relevant factors are:
⑴ activities, as is the androgen-dependent prostate organ.
⑵ food factors, is prostate cancer risk factors.
⑶ unhealthy living habits, such as long-term sedentary, less activities.
⑷ ethnic or genetic factors, the global high incidence of blacks, the incidence of family history of high, Statistics found that the brothers patients with prostate cancer than others the chance of prostate cancer in high-three times, but also generations of people with the disease, more than 60 years before onset.
■ asymptomatic prostate cancer early, discomfort is not enough to arouse the attention of patients
After prostate cancer, early and asymptomatic. When the tumor increased to urinary tract obstruction, appearance and benign prostatic hyperplasia similar symptoms, if gradually increase the flow slow, frequency, urgency, urinary flow interruption, not urination, incontinence or dysuria, hematuria is not uncommon, late in low back pain, anemia, lower extremity edema , bone pain, pathologic fractures, paraplegia, dysuria, oliguria, anuria, uremia, and so on.
As of early prostate cancer and asymptomatic, even if there are not, is not enough to cause the patient’s attention, and benign prostate enlargement and prostatitis with the symptoms similar to cancer, so it is difficult to distinguish early. When the tumor increased to a certain level, to have a urethral compression, often is not early. Clearly, early detection of prostate cancer is very important, especially for prostatitis, prostatic hyperplasia patients, great attention to the condition changes to prevent cancer.
Prostate cancer is not terrible, early detection and timely treatment, can be cured and do not affect life expectancy. Clearly, the early diagnosis of prostate cancer is very important.
Prostate cancer screening include the digital rectal examination, serum prostate specific antigen test and transrectal ultrasonography trilogy, in which the digital rectal examination and serum prostate specific antigen is the most basic of the two checks. General above the age of 50-year-old male, an inspection should be done every year; Unusual, again transrectal ultrasound and ultrasound-guided prostate biopsy.
■ best prostate cancer treatment is radical surgery, prevention takes from the “picky eaters” start
For early prostate cancer, the best treatment is to do radical surgery, that is, when the cancer confined to the prostate, its radical resection can be achieved cure the purpose of life, and did not affect the quality of life of patients. On the prostate capsule rupture, partial violations of prostate cancer, neoadjuvant therapy can be on the basis of considering radical surgery or surgical castration, combined with endocrine therapy.
With surgical anatomy technical level and the enhancement of retention of the radical nerve and vascular surgery, most patients can resume sexual function. Advanced prostate cancer by anti - androgen therapy, and the situation with local radiotherapy, chemotherapy or frozen treatment, the vast majority have better efficacy.
Clinical frequently encountered due to benign prostatic hyperplasia accepted the transurethral resection of prostate patients after resection of the prostate tissue pathological examination which found prostate cancer, called sporadic cancer. This type of prostate cancer for more focal type, tumor size small, well-differentiated cells, slow growth, transfer opportunities are few, good prognosis.
The prevention of prostate cancer should pay attention to the following points:
⑴ control of animal fat in food, maintaining the total calorie fat content of about 20%;
⑵ as far as possible, eat less pigs, cattle, sheep and other red meat;
⑶ eat soybean products, vegetables, fruits, cereals, which contain the phytoestrogens can reduce the incidence of prostate cancer. Especially soybean products, the daily need of potable 50 grams above;
⑷ more drinking green tea can reduce the incidence of prostate cancer.
In addition, the United States recently prostate cancer research centers oncologist Brian Molanboshi study found that eating fish and tomatoes, to prevent and reduce the incidence of prostate cancer has a role.
