In this novel analysis, investigators led past times Farhad Islami, M.D., Ph.D., of the American Cancer Society used the prevalence of known adventure factors in addition to their relative adventure (the extent to which they growth cancer risk) to guess the proportion of cancers due to those factors. They therefore applied those proportions to actual cancer information to guess the issue of associated cases in addition to deaths overall in addition to for 26 cancer types. The adventure factors included inwards the analysis were: cigarette smoking; secondhand smoke; excess trunk weight; alcohol intake; consumption of ruby-red in addition to processed meat; depression consumption of fruits/vegetables, dietary fiber, in addition to dietary calcium; physical inactivity; ultraviolet light; in addition to half dozen cancer-associated infections.
They found that inwards the U.S., an estimated 42.0% of all cancer cases (659,640 of 1,570,975 cancers) in addition to 45.1% of cancer deaths (265,150 of 587,521 deaths) inwards 2014 were attributable to these modifiable adventure factors.
Cigarette smoking accounted for the highest proportion of cancer cases (19.0%; 298,970 cases) in addition to deaths (28.8%; 169,180 deaths), followed past times excess trunk weight (7.8% of cases; 6.5% of deaths), alcohol intake (5.6% of cases; 4.0% of deaths), UV radiations (4.7% of cancers; 1.5% of deaths) in addition to physical inactivity (2.9% of cases in addition to 2.2% of deaths). Low fruit in addition to vegetable intake accounted for 1.9% of cases in addition to 2.7% of deaths, spell HPV infection accounted for 1.8% of cases in addition to 1.1% of deaths.
Lung cancer had the highest issue of cancer cases (184,970) in addition to deaths (132,960) attributable to evaluated adventure factors, followed past times colorectal cancer (76,910 cases in addition to 28,290 deaths). Several major cancers had a high proportion of cases attributable to evaluated adventure factors, including 85.8% of lung cancers, 71% of liver cancers, 54.6% of colorectal cancers, in addition to 28.7% of thorax cancers.
Other selected findings from the report:
- Smoking accounted for 81.7% of lung cancers, 73.8% of larynx cancers, 50% of esophageal cancers, in addition to 46.9% of bladder cancers.
- Excess trunk weight was associated amongst 60.3% of uterine cancers, nearly one-third of liver cancers (33.9%), 11.3% of thorax cancers inwards women, in addition to 5.2% of colorectal cancers.
- Alcohol intake was associated amongst almost half of oral cavity in addition to pharyngeal cancers inwards men (46.3%) in addition to nearly one-fourth (27.4%) inwards women, 24.8% of liver cancers inwards men in addition to 11.9% inwards women, 17.1% of colorectal cancers inwards men in addition to 8.1% inwards women, in addition to 16.4% of thorax cancers inwards women.
- UV radiations was associated amongst 96.0% of melanomas of the pare inwards men in addition to 93.7% inwards women.
- Physical inactivity accounted for 26.7% of uterine cancers, 16.3% of colorectal cancers, in addition to 3.9% of woman someone thorax cancers.
- Low fruit in addition to vegetable consumption was associated amongst 17.6% of oral cavity/pharyngeal cancers, 17.4% of laryngeal cancers, in addition to 8.9% of lung cancers.
- Red in addition to processed meat consumption accounted for 5.4% in addition to 8.2% of colorectal cancers, respectively. Low dietary fiber accounted for 10.3% of colorectal cancer cases, spell depression dietary calcium accounted for 4.9% of cases.
The authors enjoin their results may underestimate the overall proportion of cancers attributable to modifiable factors because several other potentially modifiable adventure factors could non travel evaluated due to lack of exposure data. Also, a issue of cancer types amongst likely, only as-yet unestablished associations amongst modifiable adventure factors were non considered.
"Our findings emphasize the continued take away for widespread implementation of known preventive measures inwards the solid seat down to cut back the morbidity in addition to premature mortality from cancers associated amongst potentially modifiable adventure factors," write the authors. "Increasing access to preventive wellness tending in addition to awareness nearly preventive measures should travel component of whatever comprehensive strategy for broad in addition to equitable implementation of known interventions to accelerate progress against cancer."
"In 1981, Doll in addition to Peto published what has larn a classic newspaper on the causes of cancer," said Otis W. Brawley, M.D., American Cancer Society primary medical officeholder in addition to study co-author. "Since then, volumes of information conduct hold been published that conduct hold clarified the association betwixt several of import adventure factors in addition to cancer. In this novel report, ACS scientists furnish a 21st century calculation that volition guide us inwards the years ahead."
