Prostate cancer and dimension D of the "pains"

Scientists had previously conducted studies have found that some prostate cancer patients the blood levels of vitamin D lower, suggesting that vitamin D and prostate cancer have a certain relationship, but the experiments prove that vitamin D on prostate cancer have a certain degree of inhibition of proliferation is the first time.

The University of Pittsburgh researchers found that a large number of additionalVitamin D enables the body of mice with metastaticProstate cancer to be curtailed. The findings for the prevention and treatment of human prostate cancer provides a new way.

 

University of Pittsburgh Medical Center, Ben Wright has recentlyReported that he and his colleagues will be highly metastatic prostate cancer cells transplanted into a number of mice in vivo, and then the rats were divided into two groups, one group of consecutive injections 3 weeksVitamin D, a group without any treatment. The results showed that vitamin D, a group of mice in vivo tumor volume 88% smaller than the other group, has been transferred to the lungs, a small number of 75% of the tumor, lung tumor the size of a small 85%.

 

Scientists had previously conducted studies have found that some prostate cancer patientsThe blood levels of vitamin D lower, suggesting that vitamin D and prostate cancer have a certain relationship, but the experiments prove that vitamin D on prostate cancer have a certain degree of inhibition of proliferation is the first time.

 

At present, the University of Pittsburgh researchers are vitamin D treatment of prostate cancer in early clinical trials, they will also explore other types of vitamin D andThe relationship between tumor.

 

Finnish MedicalExpertResearch

Finnish medical experts studies have shown that a lack of vitamin D will significantly increase the risk of prostate cancer risk, and will accelerateOf cancer development. In particular, 40 to 50-year-old middle-aged man, if too little vitamin D levels, the possibility of prostate cancer will increase greatly.

 

The result is a University of Tampere Medical Research Institute of the past 13 years 19000 40-year-old to 58-year-old after follow-up study of Finnish men arrived at.

 

They published a research report that the sun's rays are the most important source of vitamin D. Less in light winter, the body levels of vitamin D may decrease. ParticipatingFinnish men in the survey, more than half of people in the winter may cause deficiency of vitamin D, they risk the possibility of prostate cancer is 1.8 times normal. The study also found that 40-year-old to 51-year-old male, if low vitamin D levels, their risk of prostate cancer up to 3.5 times the normal cancer 6.3 times higher risk of proliferation.

 

The researchers analyzed that the human body, high levels of vitamin D will help to curb the proliferation of prostate cancer cell division and to supplement vitamin D intake may become a way of treating prostate cancer.

 

They pointed out that two-thirds of the human body needs vitamin D from the sun, one third from the食物. The role of solar UV is irreplaceable, and the summer should have more sun to store vitamin D, but to protect the skin. Of vitamin D from food intake is mainly through fish and milk products.

 

U.S. National Cancer Institute

The researchers said, was known as the "sunshine vitamin," vitamin D does not reduce the risk of men suffering from prostate cancer.

 

Earlier studies have shown that higher levels of vitamin D would include theColon andCancer, including breast cancer, and otherDisease prevention.

 

U.S. National Cancer Institute (National Cancer Institute) researchers surveyed 749 men with prostate cancer and 781 men without this disease, track record of the body of vitamin D concentration in the blood.

 

The researchers found that high levels of vitamin D and reduced risk of prostate cancer were not linked. The study also found that vitamin D the body if the higher risk of suffering from malignant prostate cancer is likely to increase, but this correlation between the two is statistically not significant.

 

"In our study, we did not find vitamin D in prostate cancer have any preventive effect," the U.S. National Cancer Institute researcher Jiyoung Ahn, said in a telephone interview.
