An overweight or obese person is at an increased risk for developing different types of cancers, a European research analysis shows.

The researchers compiled data from 141 studies and considered the impact of weight on 15 cancer sites on more diverse populations than had been done previously. The research covered more than 280,000 cases from North America, Europe, Australia and Asia

Researchers from two U.S. universities have developed a new vaccination technique for preventing prostate cancer and a new test to detect the disease more accurately.

Researchers at the University of Southern California (USC) developed a vaccine that stimulates immune response against prostate stem cell antigen (PSCA), a protein whose over-expression indicates a developing prostate cancer. The vaccine proved successful in arresting the growth of a prostate cancer in mice that were genetically modified to develop the disease

Men with prostate cancer are more preoccupied with survival than the sexual and urinary dysfunctions that follow after the surgical removal of their prostate. Thus, health care professionals must educate them about the side effects to help them physically and emotionally cope with the complications later.

These were the finding and recommendation of a study by researchers from the University of Florida's College of Nursing published in a recent issue of Urologic Nursing. The research studied 72 men six weeks after they underwent prostatectomy

Researchers at Japan's National Cancer Center said daily intake of at least five cups of green tea among men might reduce prostate cancer risk.

About 50 percent of men who drink five or more cups or green tea a day are lesser prone to developing prostate cancer, the study team found

A study funded by the Japanese government revealed that drinking several cups of green tea daily may aid in the prevention of the spreading of prostate cancer.

With about 50,000 Japanese men aged 40-69 as respondents, the study done by the Tokyo's Epidemiology and Prevention Division discovered that those who had a 5 cup-or-more daily intake of green tea cut their risk of spreading prostate cancer by half, as compared to those who drank less than one cup
