From after originally thought to the end of the story, the elimination of the disease, with disease farewell. However, it often tangled up, especially cancer and related diseases, is lingering.

For example, prostate cancer in some patients the tumor resection surgery shortly after illness relapse, the disease may continue to bear the torment, it is indeed worrisome.

In Singapore, prostate cancer is the first of six male cancer. Since the disease is a high incidence of cancer, the cancer mortality in men, second only to lung cancer. Over the past 30 years, cancer rates increased three-fold, to over 60-year-old patient who has the most.

The highest prevalence of prostate cancer in the United States and American blacks whites, prostate cancer is the second largest cancer killer in each claimed the lives of 30,000 Americans.

Two developments in the identification of material

Recently, American scientists through years of research, found in the human body has two protein substances logo of prostate cancer development.

They found that as a "EZH2" protein and another called "ECAD" protein material. When "EZH2" a large body of the patient, "ECAD" relative decline, which indicate that the patient will again be fought attacks.

Researchers say prostate cancer in the human body is not rapid development, with early prostate cancer who do not necessarily have to use surgical treatment immediately, could take "further development of its surveillance," however. Especially for some of the patients suffering from chronic diseases, it can be treated and avoid the adverse effects.

259 scientists have done prostate surgery in patients with prostate cancer research. Because of the recurrence of cancer usually need a few years time, the researchers tested the patients mainly in the blood and prostate-related antigens, and as to whether the growth of cancer a signal.

The researchers said that, in normal circumstances, once the prostate was removed a few such antigen test should be zero. Therefore, a judgment after surgical treatment of the patients with prostate cancer recurrence, we must observe its adoption of this antigen in the blood is rising. This means that the increase in antigen surgery, cancer has spread to other parts of the body, or that the operation was not to the cancer lesions in addition to all the net.

"One high and one low," that may relapse

According to the results of the study, 53 patients with elevated prostate antigen that has been evidence of recurrence. In these circumstances, researchers and the cancer cells of these patients had biochemical markers inspection found "EZH2" indicators of increased "ECAD" moderate decline in the indicators of patients, nearly half of cancer patients relapse.

The results showed that this protein targets, "one high and one low", indicating the possibility of recurrence of cancer patients has tripled.

Urinary Elizabeth Medical Center specialist Chen Ying senior adviser, said: "This' one high and one low 'target protein assays, but the research stage, no formal clinical use. Currently, most or through the prostate antigen (PSA) testing for prostate cancer, high accuracy. "

Cancer of the prostate

Four stages of prostate cancer, 10 years ago, because testing technology is not perfect enough, the patient was suffering from prostate cancer test, the general has come to a final or a third. Now, 30% to 50% of patients through the prostate antigen test conditions, the incidence of early or more of the second stage, greatly increasing the risk of patients recovered. The first phase of treatment (radiation or surgery), can survive for about 10 years.

Men suffering from prostate cancer, difficulty urinating, or a frequency of some patients to reduce weight, if spread to the bone, will feel pain.

Through blood tests can detect prostate antigen in the blood volume antigen is secreted by the prostate, high-volume, it is very likely suffering from prostate cancer, may also be a prostate reflects the impact, must be determined through biopsy.

Early prostate cancer can be confirmed by blood tests.

How to prevent prostate cancer

The American Cancer Society, eat low-fat, fiber foods, eat more fruits and vegetables, can prevent the risk of cancer.

Because the real cause of prostate cancer is not clear, therefore, difficult to prevent. Like age (60 years old and above the significant increase in the disease), race (African-American rate of the disease is twice the European-Americans), and family history and other risk factors are uncontrollable.

However, the American Cancer Society still propose a prevention recommendations:

One, quit.

Two, do not eat animal fat.

3, beans and selenium may be useful against prostate cancer.

4, tea, especially green tea rich in antioxidants, but also useful.

5, as the antioxidant lycopene, help to prevent DNA damage. Red grapefruit and watermelon are rich sources of lycopene.

6, vitamin E can reduce the risk of prostate cancer 30% rate of the disease. When vitamin E and selenium, taken together, the results better.

7, men over 50, should be done once a year prostate cancer screening, can do blood tests or rectal examination.
