Study Shows 50% of Cancers Based on Lifestyle


New research finds that almost half of cancer cases in the United States are due to potentially modifiable exposures. Smoking, drinking, and excess body weight stay as top cancer factors.

A new study published in CA: A Cancer Journal for Clinicians concentrated On looking into the amount of cancer cases and death that is attributable to modifiable or changeable factors like vices, body weight, and physical inactivity.

Specifically, researchers estimated the number of cancer cases and death overall for 26 kinds of cancer in adults over the age of 30 in the United States that might be attributed to preventable exposures. These include secondhand smoke exposure, smoking, excessive body weight, high consumption of red meat and processed meat, low consumption of fruits and vegetables, physical inactivity, and alcohol intake.

Utilizing data from the Centers for Disease Control and Prevention (CDC) And the National Cancer Institute (NCI), researchers of the study found that an estimated 42 percent of cancer incidences and 45.1 percent of cancer deaths could be associated with such exposures.

Among the risk factors, cigarette smoking demonstrated to have the highest association with cancer cases at 19 percent and 28.8 percent of cancer deaths. Excess body weight comes in second with 7.8 percent and 6.5 percent proportion of cases and death, respectively, followed by alcohol ingestion with 5.6 percent of cancer cases and 4 percent of cancer deaths. One of cancer cases, lung cancer remains on top, accounting for 184,970 instances and 132,960 deaths. Colorectal cancer follows with 76,910 cases and 28,290 deaths.
Cancer In The United States

In 2014, the latest year with available incidence data, there were 1,596,486 new cases of cancer and 591,686 deaths from it. It’s the second main cause of death after heart disease and is responsible for one in four deaths in the nation.

Breast cancer tops the chart for many new cancer cases, followed by Prostate cancer and bronchus or lung cancer. However, when it comes to cancer speed deaths, lung cancer tops the list, followed by breast and prostate cancer.

Results of this study show that a sizable chunk of cancer cases in the As such, researchers surmise that preventative strategies focusing on preventing exposure may decrease the number of cases and deaths from cancer. Preventive measures ought to be part of any comprehensive strategy for Broad and equitable implementation of interventions to accelerate progress against cancer,” noted researchers in their study.
