Then, scientists applied these proportions to current cancer data to estimate the number of associated cases and deaths for 26 cancer types.
Amidst the risk factors cigarette smoking demonstrated to have the most massive coalition with cancer cases at 19 percent and 28.8 percent of cancer deaths. Now, a new study suggests that almost half of the country's cancers may be preventable through decisions we make every day.
A recent research shows that almost half of the cancer deaths occur in the United States are triggered by potentially preventable risk factors, among which drinking, Smoking and excessive weight gain remain on the top.
Results of the study show that a large chunk of cancer cases in the United States may be attributable to preventable factors. Previous studies have found that environmental factors can be blamed for up to 90% of cancer cases.
The good news is that the rate of death from cancer in US has decreased by 25% over the past several decades.
The goal of the study was to calculate "the contribution of several modifiable risk factors to cancer occurrence", said the report in the journal CA: A Cancer Journal for Clinicians. Platz, who was not involved in the research, said she was "very excited" about the findings because they point out that prevention can keep cancer at bay.
A remarkable new study claims that about four in 10 cancers can be prevented by changes in lifestyle or preventive behaviors..
Platz added that the emphasis on obesity is particularly timely. "The worst part is that this is evident in children too". Excess body weight causes twice as many cancers in women as in men.
Out of the preventable cancers studied, lung cancer had the highest number of associated cases and deaths, followed by colorectal cancer.
These risk factors include cigarette smoking; secondhand smoke (SHS); excess body weight; alcohol intake; consumption of red and processed meat; low consumption of fruits and vegetables, dietary fiber, and dietary calcium; physical inactivity; ultraviolet (UV) radiation exposure; and infection with Helicobacter pylori, hepatitis B virus (HBV), hepatitis C virus (HCV), human herpes virus type 8 (HHV8), human immunodeficiency virus (HIV), or human papillomavirus (HPV).
Blame all you want on genetics, but the unholy trio of cigarettes, alcohol, and an unhealthy diet cause over 40 percent of all cancer cases in the US.
