(Ivanhoe Newswire) — About 80 percent of cancer diagnoses occur in the elderly, but many of their risk factors for the disease are behavioral, a new study revealed.
The Duke University study was done to estimate the impact measurable risk factors have on cancer in the elderly. It revealed more than 80 percent of known risk factors in individuals 65 years of age or older are potentially preventable.
Some of the risk factor/cancer links were similar to those found in The National Long Term Care Survey (NLTCS). Physical activity especially impacted colon and prostate cancers. Tobacco use was also significantly linked to lung cancer. Surprisingly, cancer risk was not related to alcohol consumption, which other studies have shown.

WEDNESDAY, Oct. 22 — Researchers have identified 26 genes associated with the most common type of lung cancer, adenocarcinoma — more than doubling the number of genes known to play a role in the deadly disease.
The discovery could help in developing individualized ways of diagnosing and treating lung cancer, the top cancer killer, the researchers said.
“Although similar, smaller cancer gene sequencing projects have been reported, our study is the largest to date and provides the statistical power to detect significantly mutated genes,” study co-author Richard Wilson, director of Washington University’s Genome Sequencing Center in St. Louis, said during a Tuesday teleconference.

NEW YORK (Reuters Health) - A study of Vietnam War era veterans shows that exposure to Agent Orange is associated with more than a two-fold increased risk of prostate cancer, earlier disease onset, and prostate cancer with more aggressive features.
“Consideration should be made to classify this group of individuals as ‘high risk’, just like men of African-American heritage and men with a family history of prostate cancer,” Dr. Karim Chamie, from the University of California Davis, Sacramento, and colleagues recommend.
