A new research shows that almost 50% of the cancer deaths are caused by preventable risk factors. This means that avoiding some bad habits could help lower a person’s risk of developing cancer and death.
Which are the Preventable Risk Factors?
American Cancer Society researchers analyzed data on cancer deaths and incidence. They observed that 42% of cancer cases in the US are linked to preventable risk factors.
Also, they noted that almost 50% of all cancer deaths in the US are linked to such causes as well. Some of the most common preventable risk factors are the exposure to smoke, alcohol intake, cigarette smoking, dietary choices, and excess body weight.
Cigarette smoking is the one noted to cause the most damage. This factor was linked to more than 28.8% of cancer deaths and 19% of all cancer cases. Obesity and being overweight were in the second place, causing more than 6.5% of cancer deaths and 7.8% of cancer cases. Alcohol intake was the third preventable risk factor as it led to 4% of deaths and 5.6% of cancer cases in the US.
“The results indicated that we can prevent a substantial proportion of cancers with the help of behavior and prevention strategies,” mentioned the lead study author, Dr. Farhad Islami
The researchers stated that they believe they underestimated the number of cancer cases which can be prevented by some lifestyle changes. Still, they also brought some good news. Over the last decades, the number of cancer deaths in the US decreased by more than 25%. Thanks to new technologies and better treatment, people diagnosed with cancer have a higher survival chance.
From the preventable cancers that were studied, lung and colorectal cancer presented the highest number of cases and deaths. Another finding shows that cancer deaths and cases connected to red meat consumption, smoking, UV radiation, HIV, and Hepatitis C infections were higher in men than in women. In comparison, the cases and deaths linked to alcohol intake, excess body weight, and physical inactivity were higher in women.
