A study from the Mayo Clinic Center for the Science of Health Care Delivery finds that advances in imaging technologies, including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), are fueling an epidemic in the diagnosis and treatment of thyroid cancers that are unlikely...
Gene That Helps Control Aging Is Linked to Multiple Myeloma
A telomerase RNA component gene called TERC, which is responsible for regulating the length of caps on the ends of DNA molecules and believed to be involved in the aging process, has been linked to the development of multiple myeloma, according to a study published in Nature Genetics. Researchers...
Experts Discuss Challenges in Counseling Patients About Contralateral Prophylactic Mastectomy
Many factors play into why women diagnosed with breast cancer often choose overly aggressive treatment even when there is little evidence to show clinical benefit: the shock and fear of suddenly being confronted with a major health threat, the impression of having to make treatment decisions...
NCI Working Group Recommends Changes to Screenings, Treatments, and the Definition of Cancer
A growing concern that hundreds of thousands of men and women are undergoing unnecessary and sometimes harmful treatments for premalignant and slow-growing, low-risk cancerous lesions that may never cause harm has led scientists from a working group of the National Cancer Institute to recommend a...
CDC Report Shows Stagnated HPV Vaccination Rate for Girls
For the first time since the human papillomavirus (HPV) vaccine became available for adolescent girls in 2006, the vaccination rate for the teenagers has stalled, according to data published in the Centers for Disease Control and Prevention’s (CDC’s) Morbidity and Mortality Weekly...
Alternate-day, Low-dose Aspirin May Reduce Colon Cancer Risk
Low-dose aspirin (100 mg) taken every other day may reduce a woman’s risk of developing colon cancer, according to an observational study published in the Annals of Internal Medicine. The findings are based on a large long-term study of 38,876 healthy women enrolled in the Women’s...
Aspirin May Help Prevent Cancer in Patients with Barrett’s Esophagus
Although aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) have been shown to reduce cancer mortality by 20%, exactly why these drugs reduce the number of cancer incidences and deaths is not known. Now, a small longitudinal study of 13 patients with Barrett’s esophagus is...
Scientists Develop Mathematical Model to Predict Cancer Cells’ Resistance to Therapy
New research using mathematical models of different types of cancer—including melanoma, pancreatic, and colorectal—to determine the evolutionary dynamics of lesions in response to treatment is revealing why and how cancer cells resist targeted therapies. The study by Ivana Bozic, PhD,...
Study Shows HPV Vaccine Reduced Rate of Infection in Teenage Girls by 56%
A new government study investigating the prevalence of human papillomavirus (HPV) infections in females aged 14 to 59 before and after the introduction in 2006 of the HPV vaccine found that the rate of the HPV infection dropped by 56%, decreasing from 11.5% in 2006 to 5.1% in 2010 among female...
Global Alliance Is Formed to Share Genomic Data
This month, an international group of over 70 research and health-care organizations, academic centers, and medical societies, including ASCO, signed a letter of intent to form a global alliance to make medicine more effective by consolidating the world’s databases of genomic information. The ...
Human Genes May Not Be Patented, Rules the Supreme Court
The U.S. Supreme Court ruled unanimously on Thursday that isolated human genes may not be patented. However, the creation of synthetic forms of DNA, known as complementary DNA (cDNA), is eligible for patent protection. The decision resolves the question brought before the Supreme Court justices in...
