Should People Over Age 75 Be Screened for Colorectal Cancer?Screening people for colorectal cancer after age 75 may be beneficial, a new study suggests. The findings provide helpful information for physicians to use in discussing screening choices with their older patients.
-
Texting May Help Reduce Disparities in Colorectal Cancer ScreeningCombining text messaging with mailing people free at-home FIT kits helped increase screening for colorectal cancer among a predominantly Black population, a new study has found. It’s part of a larger effort to reduce disparities in cancer screening.

ACS’s Updated Cervical Cancer Screening Guidelines ExplainedUpdated cervical cancer screening guidelines from the American Cancer Society recommend HPV testing as the preferred approach. NCI’s Dr. Nicolas Wentzensen explains the changes and how they compare with other cervical cancer screening recommendations.
-
Many Older Adults Screened Unnecessarily for Common CancersMany older adults are being screened for cancer who no longer need to be, a new study shows. Based on a nationwide survey, the study found that at least half of older US adults had received at least one unnecessary cancer screening test in the previous few years.

How Does Ovarian Cancer Form? A New Study Points to MicroRNAA microRNA—a molecule made by cells to turn genes on and off—called miR-181a may help high-grade serous ovarian cancer form, a study has found. The scientists think the microRNA could potentially help doctors detect ovarian cancer earlier.

Liquid Biopsy Detects Brain Cancer and Early-Stage Kidney CancerResults from two studies show that a liquid biopsy that analyzes DNA in blood accurately detected kidney cancer at early and more advanced stages and identified and classified different types of brain tumors.
-
Study Examines Whether Blood Test Can Identify Early CancersA blood test combined with imaging tests detected tumors—some at an early stage—in women with no history of cancer or symptoms, a recent study showed. The test also mistakenly indicated some women had cancer when further testing showed they didn't.
-
Mapping Cancer Genomic Evolution Offers Insights into Tumor DevelopmentScientists have mapped the evolution of 38 cancer types, noting common gene and protein alterations that occur early, in the middle of, and late in their development. The hope is that these maps create opportunities to identify cancers much earlier.
-
MGUS to Myeloma: Study Suggests Risk of Progression Can ChangeA person’s risk of progressing from a benign condition called monoclonal gammopathy of undetermined significance (MGUS) to the blood cancer multiple myeloma can change over time, according to a new study.
-
Study Suggests Reviewing Lung Cancer Screening Criteria for African AmericansClinical recommendations on who should be screened for lung cancer may need to be reviewed when it comes to African Americans who smoke, findings from a new study suggest.
-
Laser-Based Device Detects and Kills Melanoma Cells in the Blood, Study FindsResearchers have developed a device that uses lasers and sound waves to scan circulating blood for melanoma cells. In a small study, the device accurately detected and reduced the amount of cancer cells in participants’ blood.
-
Metastatic Colorectal Cancer May Spread Early in the Disease, Study FindsMany colorectal cancers likely have spread long before the original tumor is detected, researchers have found. The findings suggest the need for very early detection and could help identify patients who need more aggressive systemic treatments.
-
Could a Vaccine Prevent Colorectal Cancer in People with Lynch Syndrome?Findings from an NCI-funded study suggest a new vaccine approach may have the potential to prevent colorectal cancer in people with Lynch syndrome, an inherited condition that increases an individual's risk for developing certain types of cancer.
-
After Lung Cancer Screening, Follow-Up Procedures May Be Riskier than ThoughtIn everyday medical care, there may be more complications from invasive diagnostic procedures performed after lung cancer screening than has been reported in large studies.
-
For Early-Stage Lung Cancer, Study Identifies Potential New Biomarker, Treatment TargetA new study has identified a potential biomarker of early-stage non–small cell lung cancer (NSCLC). The biomarker, the study’s leaders said, could help diagnose precancerous lung growths and early-stage lung cancers noninvasively and distinguish them from noncancerous growths.
-
Genomic Test Helps Identify Thyroid Nodules That Don’t Require SurgeryThe test measures genomic changes in thyroid biopsy samples and generates a score based on how strongly each change is associated with thyroid cancer. A study showed the test accurately identified samples that, after surgery, were found to be benign.
-
For HPV-Positive Women, Test Can Guide Cervical Cancer Screening Follow-UpA new test can help to improve the clinical management of women who screen positive for HPV infection during routine cervical cancer screening, an NCI-led study has shown.
-
Study Provides Closer Look at Postmenopausal Bleeding and Endometrial CancerA new study has found that 90% of postmenopausal women diagnosed with endometrial cancer reported vaginal bleeding before their diagnosis. Approximately 9% of postmenopausal women who saw a doctor for bleeding, the study showed, later received an endometrial cancer diagnosis.
