Half of all women experience false positive mammograms after 10 years of annual screening

A study published in JAMA Network Open found that half of all women will experience at least one false positive mammogram over a decade of annual breast cancer screening with 3D mammography. The risk of false positives is lower for women screened every other year, and non-dense breasts also show a lower false positive risk.

City of Hope researcher advises doctors against overreliance on a popular liquid biopsy used to screen for colorectal cancer recurrence

A recent study by City of Hope researchers highlights the limitations of Signatera, a popular liquid biopsy test for detecting colorectal cancer recurrence. The study found that standard-of-care CT scan plus CEA blood draw test was more effective in identifying early disease recurrence.

New risk algorithm would improve screening for prostate cancer

A new study developed an algorithm estimating a person's risk of developing prostate cancer based on age and two prostate cancer markers. The approach was found to reduce the number of false positives by three quarters compared to a standard PSA test while catching the same proportion of cancers, making screening safer and more accurate.

Breast cancer overdiagnosis may not happen as frequently as previously thought

A modeling study suggests that breast cancer overdiagnosis may occur in about 15% of screen-detected cases, rather than the estimated 30%. This could spare around 25,000 women unnecessary treatment. Researchers used data from the Breast Cancer Surveillance Consortium to estimate the rate of overdiagnosis.

Colon cancer screening can erase disparities in outcomes

A regionwide, structured colorectal cancer screening program eliminated disparities in colorectal cancer death rates between Black and white Kaiser Permanente members. Organized screening outreach markedly increased screening rates and led to significant decreases in incidence and death rates.

MRI may lower breast cancer deaths from variants in 3 genes

Annual MRI screenings starting at ages 30-35 may reduce breast-cancer mortality by more than 50% among women who carry certain genetic changes in three genes. The predictions involve pathogenic variants in ATM, CHEK2 and PALB2 genes – which collectively are as prevalent as the much-reported BRCA1/2 gene mutations.

Follow-up costs can add up if a free cancer screening shows a potential problem

New studies from Michigan Medicine researchers aim to remove financial barriers for patients who receive abnormal test results, enabling them to complete the diagnostic process. The findings suggest that removing cost barriers could save lives by increasing screening uptake, particularly among women and underserved populations.

Tiny antenna enables portable biomedical, food-analysis, and other gadgets driven by integrated nano- and terahertz technologies

Researchers have designed a tiny and flat antenna for receiving and transmitting terahertz signals, enabling the miniaturization of THz devices. The new design integrates the antenna with the system, eliminating the need for bulky silicon lenses and reducing optical power required.

Little test, big impact: dipstick screening for hematuria

Researchers in Japan evaluated the cost-effectiveness of adding dipstick hematuria screening to a mass health check-up program. The study found that including routine testing for hematuria would promote early detection and treatment, leading to cost savings and improved patient outcomes. This cost-effective approach has the potential t...

Genetic and lifestyle calculator reveals which younger adults are most at risk of colorectal cancer

A new polygenic risk score is made from genetic variants and lifestyle factors to identify younger adults at risk of colorectal cancer. The study found those with the highest risk scores were four times more likely to develop colorectal cancers than those with lower scores.

Faulty BRCA genes linked to prostate and pancreatic cancers

A recent study has found that faulty versions of the BRCA1 and BRCA2 genes are associated with an increased risk of developing prostate and pancreatic cancers in men. The study analyzed data from over 3,200 families and estimated that men who carry a BRCA2 mutation have a 27% risk of developing prostate cancer by age 80.
