National screening benchmarks for finding polyps during a colonoscopy might be too low
A recent Mayo Clinic study found that using high-definition imaging tools during screening colonoscopies can increase adenoma detection rates by up to 25% in women and 41% in men. The study suggests that national benchmarks for detecting polyps may be too low, especially when using advanced technology.
Pioneering study shows that local volunteers increase early breast cancer detection rates in a low-income rural area

American Cancer Society recommends informed decision making in lung cancer screening
The American Cancer Society recommends low-dose computed tomography (CT) screening for patients aged 55-74 with a 30-pack-year smoking history. A thorough discussion of benefits, limitations, and risks is essential before screening. Screening can reduce lung cancer mortality in high-risk groups.
Hispanics leery of health care providers, often avoid cancer screenings, Moffitt study shows
A Moffitt study found Hispanics are nearly twice as likely to avoid cancer screenings due to fears and mistrust of medical professionals. The researchers suggest improving communication and building trust with patients is crucial for increasing screening rates, particularly among Hispanic and lower-income minorities.
Costly breast cancer screenings don't add up to better outcomes
A recent study published in JAMA Internal Medicine found that higher spending on breast cancer screenings does not result in improved outcomes for older women. The research team analyzed Medicare expenditures and screened female beneficiaries over two years, discovering substantial geographic variation in costs.
Rural dwellers less likely to follow cancer screening guidelines
A recent study found that rural US residents are less likely to follow colorectal cancer screening guidelines due to the time required for travel and limited access to healthcare. The researchers also noted that lack of health insurance and primary care provider shortages contribute to this disparity.
Breath test could possibly diagnose colorectal cancer
Researchers have developed a simple breath analysis technique that can screen for colorectal cancer with an accuracy of over 75%. The method analyzes volatile organic compounds in exhaled breath, which are different in patients with cancer.
Models developed from the PLCO may help identify at-risk patients for adverse smoking outcomes
Researchers developed models from PLCO data to predict smoking status, finding that relapse and continued smoking are linked to demographic and tobacco-related characteristics. The models suggest variables like longer-term smokers, recent quitters, and pipe or cigar smokers are at higher risk for relapse.
Increased use of colonoscopy screening could explain decrease in colorectal cancer rates
A recent study from Stanford University School of Medicine found that increased use of colonoscopy screening may be responsible for the significant decrease in colorectal cancer incidence over the past decade. The study analyzed data from over 2 million patients and found a correlation between Medicare's extension of colonoscopy covera...

Fecal occult blood testing effective in colonoscopy screenings
A study published in the Journal of the National Cancer Institute found that fecal immunochemical testing (FIT) is more effective than guaiac fecal occult blood testing (gFOBT) in colonoscopy screenings, increasing attendance and diagnostic yield while reducing false positives. FIT is also cost-effective and clinically beneficial for d...
Study shows no increased risk of breast cancer for non-carriers in families with BRCA gene mutation
A population-based analysis found that close relatives of women with breast cancer who don't carry the BRCA mutation have a similar risk to the general population. The study suggests they may not need extra cancer screening and preventive measures.
Cheaper and easier isn't necessarily better in new colon cancer screening procedures
Fecal immunochemical testing (FIT) is an accurate predictor of colorectal cancer, but it remains inferior to colonoscopy for prevention. Yearly FIT screenings may allow treatment to follow closely on the heels of discovery, but practices with repeat testing over time perform poorly.
UT Southwestern, Parkland partner for $6.3 million NCI grant to improve colorectal cancer screenings
