A recent study has suggested that men with larger waistlines could be at higher risk of developing aggressive prostate cancer.

Research on 140,000 men from eight European countries found that a 4in larger waist circumference could increase the chances of getting the cancer by 13%.

Men were most at risk when their waist was bigger than 37in, the University of Oxford study found.

Prostate cancer is the most common cancer in men.

Weight loss could be a potential factor in regaining erectile function by losing 5 to 10 percent of the body weight

The study, which was presented at the European Obesity Summit in Gothenburg, Sweden, looked at the association between body measurements in men in their 50s and prostate cancer risk over 14 years.

In that time, there were about 7,000 cases of prostate cancer, of which 934 were fatal.

The researchers found that men with a higher body mass index (BMI) and waist circumference had an increased risk of high grade prostate cancer, an aggressive form of the disease.

For example, men with a waist size of 37in had a 13% higher risk of aggressive prostate cancer than men with a waist of 33in.

Scientists also observed a higher risk of dying from prostate cancer with increased BMI and increased waist circumference.
