Study Adds to Debate about Mammography in Older WomenFor women in their 70s and older, the risk of overdiagnosis with routine screening mammography is substantial, a new study suggests. The findings highlight the need for conversations between older women and their health care providers about the potential benefits and harms of continuing screening mammography.

Catch-Up HPV Testing May Help Prevent Cervical Cancer in Some Over Age 65It may be worthwhile for some individuals between ages 65 and 69 to get tested for HPV, findings from a Danish study suggest. Specifically, the testing may help prevent cervical cancer among those who haven’t had cervical cancer screening for at least 5 years.

Study Identifies Potential Warning Signs of Colorectal Cancer in Younger AdultsResearchers have identified four warning signs that they believe may help identify colorectal cancer early in younger adults. The signs or symptoms are abdominal pain, rectal bleeding, diarrhea, and iron deficiency anemia.

Can Cancer Prevention Be Better Integrated into Primary Care?When it comes to cancer prevention, primary care clinicians play a critical role. But there are many barriers to integrating cancer prevention into primary care. Researchers are trying to better understand those barriers and how best to overcome them.

3-in-1 Approach Helps Women in Rural Areas Get Cancer ScreeningsIn a new study, providing rural women with an interactive video about cancer screening and follow-up calls with patient navigators helped get them up to date on screenings for breast, cervical, and colorectal cancer.

When Prenatal DNA Tests Point to CancerAn NIH-led study called IDENTIFY is analyzing what happens when prenatal blood tests in a pregnant person suggests the person may have cancer. Dr. Diana Bianchi and Amy Turriff talk about their experience with the study thus far.
-
Can the New “Omics” on the Block Find Liver Cancer in Blood?Researchers have developed a blood test that, in a preliminary study, accurately detected liver cancer, including in people with early-stage disease. The test uses a new type of technology called fragmentomics to analyze bits of DNA in the blood.
-
Cancer Screening Guidelines Often Lack Information on Potential Harms, Study FindsIn a review of 33 cancer screening guidelines, researchers have found that many don’t adequately capture the potential harms of cancer screening. Providing information on harms is critical so people can have informed discussions about screening with their health care providers, the researchers noted.
-
Working to Close the Cancer Screening Gap Caused by COVIDMany hospitals and community health centers are trying to increase cancer screening rates after the COVID pandemic caused them to plummet. The largest effort aims to add a total of 70,000 additional monthly screening tests over a 6-month period.

Colonoscopy after Positive FIT Test Cuts Risk of Colorectal Cancer DeathPeople who had a positive FIT result (signs of blood in the stool) but didn’t get a follow-up colonoscopy were twice as likely to die of colorectal cancer as those who did get a colonoscopy, a new study found.
-
Study Adds to Debate about Screening for MelanomaRegular skin cancer screening leads to many diagnoses of very early-stage melanomas, results from a new study suggest. The results add to a debate about whether screening is fueling an overdiagnosis of melanoma in the United States.
-
Screening for Many Cancers with One Test: Uncertainty AboundsProgress has been made on developing noninvasive tests that may be able to find many cancers early. But, as NCI’s Dr. Phil Castle explains, there’s still much to learn about these multi-cancer early detection tests before they become widely used.
-
Can Artificial Intelligence Help See Cancer in New, and Better, Ways?Researchers have been developing artificial intelligence (AI) tools that could make cancer imaging faster, more accurate, and more informative. But there are also questions about whether these tools are ready for doctors’ offices, whether they will actually help people, and whether that benefit will reach all—or only some—patients.
-
Why Are Many Women Overdue for Cervical Cancer Screening?The rates of timely cervical cancer screening fell between 2005 and 2019, researchers found, and disparities existed among groups of women. The most common reason for not receiving timely screening was lack of knowledge about screening or not knowing they needed screening.
-
New Risk Model Aims to Reduce Breast Cancer Disparities in Black WomenMost breast cancer risk tools were developed with data mainly from White women and don’t work as well for Black women. A new tool that estimates risk for Black women may help identify those who might benefit from earlier screening, enabling earlier diagnosis and treatment.
-
Why Have Thyroid Cancer Diagnoses Spiked for US Women?Women are far more likely than men to be diagnosed with small thyroid cancers that probably would have never caused problems during their lifetime, a new study finds. The results may help explain why thyroid cancer seems to be more common in women.
-
Advancing Cancer Prevention: A Conversation with NCI’s Dr. Philip CastleThe director of NCI’s Division of Cancer Prevention, Dr. Philip Castle, discusses the division’s priority areas and his vision for making more rapid progress in cancer prevention, including moving toward precision prevention and immunoprevention.
-
Could a Diabetes Diagnosis Help Detect Pancreatic Cancer Early?Numerous studies have pointed to a link between new-onset diabetes and pancreatic cancer. Now, several large NCI-supported studies are testing ways to pick out those people whose diabetes might be a sign of early pancreatic cancer, when treatments may be more effective.
-
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.
