Obesity increases the risk of incurable forms of prostate cancer


 



British doctors have discovered that men with a high body mass index are more likely to die of prostate cancer than others.



The press office of the European Society for the Study of Obesity (EASO) notes that the risk of fatal forms of tumor increases by 10% per five BMI points.


According to the Office's report, "It is not yet clear whether obesity helps to develop dangerous forms of prostate cancer, or is due to delayed diagnosis of cancer. However, these conclusions must become an incentive for all men to eliminate excess weight. "



According to recent estimates by the World Cancer Research Foundation (WCRF), prostate cancer is the second most prevalent, affecting 1.2 million men and destroying the lives of 360 1,000 men annually. As a general rule, this type of cancer affects older men and leading deaths from tumors.


Prostate cancer is characterized by its slow progression, allowing doctors to diagnose it before metastasis and remove it with some risk to the patient. But some tumors are particularly aggressive, their growth cannot be suppressed using testosterone inhibitors and other drugs.


What are the consequences of male obesity?


  • A scientific team chaired by Perez Cornague studied the effect of obesity on the development of aggressive forms of prostate cancer. In order to obtain the necessary information
  • the scientific team analysed the data collected under the UK Biobank project, which involved 218 thousand British men.
  •  all of whom agreed to undergo comprehensive examinations, including determination of body fat mass and tests for identifying different tumour indicators. 
  • The health status of these men has been followed for 11 years, allowing scientists to comprehensively study the impact of excess weight on the likelihood and nature of prostate cancer development.


The results of the study showed that the likelihood of developing severe forms of untreatable cancer in obese men is very high. A BMI rise of 5 points increases this risk by 10 per cent, and each additional 10 centimetres in the waist increases this risk by 7 per cent.


However, scientists cannot say whether obesity itself contributes to the development of severe forms of prostate cancer, or their findings are that men with obesity rarely review doctors. They are therefore diagnosed with late-stage prostate cancer.


The researchers hope that these results and experiments on animals will help to get an accurate answer to this question.







Exciting study. Food that doubles its "excess consumption" risk of prostate cancer



A new study of 29 alpha and 133 men in Finland found that individuals who took 2000 mg of calcium or more per day saw a marked increase in the risk of prostate cancer.


The high consumption of dairy products was also associated with an increased risk of disease, which researchers attributed to the calcium found in those foods.


Worryingly, another study published in the journal Cancer Research of the American Cancer Research Society found that calcium consumption among Chinese men -- even at relatively low levels and from non-dairy food sources (such as soybeans, cereals and vegetables) -- can increase the risk of prostate cancer.


Senior researcher, Leslie M. Butler, Assistant Professor of Epidemiology at Colorado State University: "Our results support the idea that calcium is a dangerous factor in enhancing the role of prostate cancer development."


Some studies in the population of North America and Europe linked high dairy consumption to an increased risk of prostate cancer. Some studies have indicated that calcium in milk is the causal factor, but the evidence is unclear.


Using data from the China Health Study in Singapore, researchers assessed whether dietary calcium increased the risk of prostate cancer in 27,293 men, aged 45 to 74, with low dairy consumption.


In the study, participants completed a questionnaire assessing their diet over the past year. Of these men, 298 were diagnosed with prostate cancer.


Butler and his colleagues at Colorado State University, the National University of Singapore and the University of Minnesota basically assessed participants' diet.


The results showed a 25% increased risk of prostate cancer, when compared to those who took (on average) 659 mg against 211 mg of total calcium per day, according to the study.


According to the NHS, other risk factors include:


  1. - Age progression
  2. - Ethnic group - prostate cancer is more common among men of African descent and the Caribbean than Asian men.
  3. - Family history "Genetics of inheritance"
  4. - Obesity - A balanced diet and regular exercise may reduce a person's risk of prostate cancer.
