Study highlights cancer risk from millions of CT scans performed annually

ct scan cancer risk

CT scans diagnose afflictions from tumors to kidney stones to life-threatening diseases and injuries, such as aneurysms and blood clots leading to stroke.

But the radiation emitted by this essential diagnostic tool may cause more harm than previously known and could eventually be responsible for roughly 5% of all cancers diagnosed in the U.S. in a single year, a new study finds.

"Medical imaging has potential benefits," said radiologist Dr. Rebecca Smith-Bindman, an epidemiology professor at the University of California, San Francisco, and lead author of the study published Monday in JAMA Internal Medicine. "It has potential harms as well, and it's really important to balance them."

Scientists long ago established that ionizing radiation emitted by computed tomography, or CT, scans increases cancer risk. But, since 2007, use of the imaging technique has surged 35%, the study says, due in part to growth in what Smith-Bindman and her colleagues call "low-value, potentially unnecessary imaging."

‘Bureaucratic cruelty’: 9/11 responders and survivors shaken by US health cuts

First responders

A program that provides free healthcare to first responders and survivors of the World Trade Center terror attacks has been in turmoil for months, with services cut, restored and cut again as part of the Trump administration’s “restructuring” of the federal health department.

Following the most recent cuts, groups representing survivors and even Democratic US senators say they have no clarity on how the program will continue to provide benefits.

“This is bureaucratic cruelty,” said Michael Barasch, an attorney who represents thousands of first responders and survivors of the attacks. Barasch himself was a downtown Manhattan office worker on September 11.

“You’ve got people with [post-traumatic stress disorder], which was diagnosed from all the body parts they were picking up, all that trauma – these people rely on treatment. Can you imagine their level of anxiety? Their level of anxiety is skyrocketing,” said Barasch.

Wyoming governor vetoes ultrasound requirement for medication abortions

Wyoming health clinic

A bill that would have required women seeking medication abortions to get ultrasounds has been vetoed by Wyoming’s Republican governor, who questioned whether it was reasonable and necessary especially for victims of rape and incest.

“Mandating this intimate, personally invasive, and often medically unnecessary procedure goes too far,” Mark Gordon wrote in a letter explaining his veto late on Monday.

Groups working to maintain abortion access in Wyoming – the first state to attempt to explicitly outlaw medication abortions – praised the veto even though Gordon over the past three years has signed into law several bills seeking to ban the procedure.

“It’s important that women are able to access this healthcare without undue and unnecessary burden,” Christine Lichtenfels, executive director of the abortion access advocate Chelsea’s Fund, said on Tuesday.

Texas measles outbreak grows to 90 cases, worst level in 30 years

Measles outbreak worsens

The measles outbreak in Texas has grown to at least 90 cases, reaching historic levels, according to officials.

Since late January, 90 cases of measles have been identified in the South Plains region, the state’s department of state health services (DSHS) reported Friday. At least 16 patients have been hospitalized as a result.

The majority of reported measles cases were in children and teenagers; minors between the ages of five and 17 accounted for 51 cases. Children under four made up 26 cases. Most patients’ parents either had chosen to not immunize them against the highly contagious illness through vaccines meant to prevent the potentially deadly illness and its spread, or their vaccination status was unknown.

NIH cuts overhead funding for research

nihThe National Institutes of Health (NIH) on Friday made a significant reduction in grants reserved for research institutions, a decision that may significantly impact American higher education.

The NIH said it provided over $35 billion in grants to more than 2,500 institutions in 2023, announcing that it will now limit the amount granted for “indirect funding” to 15 percent. This funding helps cover universities’ overhead and administrative expenses and previously averaged nearly 30 percent, with some universities charging over 60 percent.

The change will take effect on Monday, and will save roughly $4 billion annually, per the NIH.

US Food and Drug Administration bans Red 3 dye in foods citing cancer risk

Red dye banned by fda

US regulators on Wednesday banned the dye called Red 3 from the nation’s food supply, nearly 35 years after it was barred from cosmetics because of potential cancer risk.

Food and Drug Administration officials granted a 2022 petition filed by two dozen food safety and health advocates, who urged the agency to revoke authorization for the substance that gives some candies, snack cakes and maraschino cherries a bright red hue.

The agency said it was taking the action as a “matter of law” because some studies have found that the dye caused cancer in lab rats. Officials cited a statute known as the Delaney Clause, which requires FDA to ban any additive found to cause cancer in people or animals.

5 risk factors to watch out for this respiratory virus season

Risks for illness this flu season

Respiratory viruses impact everyone differently. Some may miss a few days of work, while others face a long recovery. Certain risk factors can make you more vulnerable to getting very sick from COVID-19, flu and RSV.

To stay healthy, people at high risk and their loved ones should take precautions — whether they’re an active senior staying up to date on their shots or a pregnant person getting vaccinated to protect their unborn baby. Vaccines are your best defense against getting very sick.

Here are five key risk factors to know:

1.Age. Grandparents and grandkids share a special bond, but during respiratory virus season, older adults need to take extra care. People ages 65 and older are at a higher risk of developing severe illness from COVID-19 and flu, while those 75 and older are at a higher risk for severe RSV. Additionally, older adults who are 60 to 74 and live in nursing homes or have health conditions, such as heart and lung disease, obesity, diabetes, kidney disease and other chronic conditions, are at higher risk of complications and more severe illness from RSV
