Cancer is a disease of aging, that being said, the latest research study out of the UK shows that what we put in our bodies directly affects our chances of developing the disease.
The researchers involved said the results consistently suggested that 70-90% of the risk was due to environmental factors.
Doctor Emma Smith, of Cancer Research UK, said: ‘Healthy habits like not smoking, keeping a healthy weight, eating a healthy diet and cutting back on alcohol are not a guarantee against cancer, they do dramatically reduce the risk of developing the disease.’
There seems to be a controversy in the medical community as to how much of a factor errors in DNA caused aging are to blame for cancer versus the way we live our lives.
Scientists previously thought that most cases of cancer were due to ‘bad luck’, rather than an unhealthy lifestyle. The previous study showed that 2 out of 3 cancer patients had issues with random mutations in their genes rather than possible poor choices they had made.
The latest study involved four analyzes of the causes of cancer and used some of the same data as the first piece of research.
However, this time, the study came to the opposite conclusion, suggesting that cancer incidence is far too high to be explained by simple mutations in cell division alone.
Researchers said that, if random mutations were to blame, there would be far fewer cases of cancer than there are.
Doctor Yusuf Hannun, of Stony Brook University, said that while luck plays a role, factors in the world around us are much more important.
These include diet, alcohol, cigarettes, sunburn, some viruses, pollution and likely other factors that have yet to be identified.
The researchers also looked at previous studies which have shown how immigrants moving from low cancer incidence to countries with high cancer incidence soon develop the same tumour rates, suggesting the risks are environmental rather than biological or genetic.
Nearly 75 per cent of the risk of colorectal cancer is now believed to be due to diet.
That being said, you should head over to the World Health Organization website where they explain how analysis of data from 10 studies estimated that every 50-gram portion of processed meat eaten daily increases the risk of colorectal cancer by about 18%.
