It is known that obesity is a big risk factor for many diseases, such as cancer, type 2 diabetes, and heart disease.
In a new study, researchers found that obesity may bring new health risks to men with prostate cancer risk.
They found that obesity could affect the results of the most widely used test for prostate cancer.
This means obese men may get an inaccurate prostate cancer diagnosis, which could affect their treatment.
The study was conducted by a team from the University of Adelaide, Australia.
In the study, the team used data from 970 South Australian men from the Florey Adelaide Male Ageing Study.
They examined the effects of obesity on PSA levels detected in blood and the influence of the hormones, testosterone, and estrogen.
Previous research has shown that elevated levels of prostate-specific antigen (PSA) in the blood can indicate prostate cancer and lead to further diagnosis.
PSA is increased by the male sex steroid hormone, testosterone.
The team found that the concentration of PSA in the blood is lower in men with severe obesity than in lean men.
They explain that this can be attributed to lower concentrations of circulating testosterone in obese men.
The team suggests that the finding has important implications for detecting and monitoring the most common form of cancer in men.
It is important for doctors to interpret PSA levels in obese men more carefully.
The supervisor of the study is Professor Gary Wittert.
The study is published by the Society for Endocrinology.
