THURSDAY, Aug. 6, 2020 -- Contrary to recommendations set by the U.S. Preventive Services Task Force, many Americans are getting screened for cancer even when old age or poor health would likely render such screenings risky and pointless, new research finds.
The task force notes that screening always entails some degree of risk, and cancer treatment can be harsh. So the reasoning is that neither the risk nor the ordeal are worth it for those who don't have long to live anyway.
THURSDAY, July 23, 2020 -- Scientists are working on a blood test that may catch five common cancers years sooner than current methods.
The blood test, which is still experimental, hunts for certain genetic "signatures" associated with tumors. Researchers found that it can detect five types of cancer -- colon, esophageal, liver, lung and stomach -- up to four years earlier, compared to routine medical care.
FRIDAY, July 31, 2020 -- Cities around the world are increasingly turning to streetlights emitting so-called "blue light," and it's also common in smartphones, laptops and tablets. Now, a study hints that excess exposure to blue-spectrum light might raise a person's odds for colon cancer.
As a team of Spanish researchers noted, prior studies have suggested that blue light emitted by most white LEDs (light-emitting diodes) and many tablets and phones was linked to ailments such as sleep disorders, obesity and an increased risk of various cancers, especially among night-shift workers.
TUESDAY, July 14, 2020 -- Many cancer patients have faced delays to their health care during the coronavirus pandemic, but with what consequences?
Researchers at Beth Israel Deaconess Medical Center in Boston analyzed 15 years of data to determine how long surgery for certain types of cancer can be delayed without harming patients' chances of survival. The study began in early spring, as the pandemic led many hospitals to cancel or postpone non-emergency procedures, including surgery for cancer.
TUESDAY, July 7, 2020 -- CT scans have been proven to help spot lung cancer early and save lives. Now, updated expert recommendations could double the number of Americans who are eligible for the yearly screening.
The recommendations -- from the U.S. Preventive Services Task Force (USPSTF) -- would expand the definition of "high risk" for lung cancer. That's expected to not only increase the number of people eligible for screening, but also to have a particular benefit for women and Black Americans.
MONDAY, June 22, 2020 -- Statin drugs, used for decades to treat high cholesterol, may also reduce deaths for women with ovarian cancer, a new study suggests.
"These drugs are appealing as they are widely used, inexpensive, and well-tolerated in most patients. The associated reduction in ovarian cancer mortality is promising," said lead researcher Dr. Kala Visvanathan, a professor of epidemiology and oncology at Johns Hopkins Bloomberg School of Public Health in Baltimore.
