WEDNESDAY, Nov. 13, 2019 (HealthDay News) -- More Americans are surviving lung cancer in recent years, but very few people at high risk are getting the recommended screening.

Those are the highlights from the latest "State of Lung Cancer" report from the American Lung Association (ALA), published Nov. 13.

There are positive trends, including the survival numbers: Compared wi...

THURSDAY, Oct. 24, 2019 (HealthDay News) -- Could a person's risk for lung cancer someday be determined with a quick swab of the nose?

If the preliminary findings of a new study are any indication, it's a distinct possibility.

The experimental nasal swab relies on the fact that most lung cancer patients are current and former smokers. It's meant to be a noninvasive means of ...

THURSDAY, Sept. 12, 2019 (HealthDay News) -- CT lung cancer screening can detect other serious smoking-related conditions, such as heart disease, osteoporosis and emphysema, researchers say.

Medical experts consider lung cancer screening an effective way to detect malignant tumors at earlier, more treatable stages. Now, new research suggests low-dose CT scans of the lungs could also i...

TUESDAY, Sept. 3, 2019 (HealthDay News) -- Despite efforts from medical groups to cut down on the overuse of CT scans and MRIs for safety reasons, their use has instead increased, a new study shows.

"Medical imaging is an important part of health care and contributes to accurate disease diagnosis and treatment, but it also can lead to patient harms such as incidental findings, overdia...

WEDNESDAY, July 24, 2019 (HealthDay News) -- Use of risky CT scans during pregnancy has risen significantly in North America in the past two decades, a new study finds.

"It's important to quantify exposure to ionizing radiation because it can cause cancer and birth defects, and should be kept to a minimum, especially during pregnancy," said co-lead author Marilyn Kwan. She's a senior ...

MONDAY, July 15, 2019 (HealthDay News) -- A newer form of lung cancer screening may mean fewer deaths from the disease, a new study contends.

Using low-dose computed tomography (LDCT) instead of X-rays helped reduce lung cancer deaths in current and former smokers, the study authors said.

"Lung cancer is the leading cause of cancer death worldwide, and early detection and t...

WEDNESDAY, March 13, 2019 (HealthDay News) -- The term artificial intelligence (AI) might bring to mind robots or self-driving cars. But one group of researchers is using a type of AI to improve lung cancer screening.

Screening is important for early diagnosis and improved survival odds, but the current lung cancer screening method has a 96 percent false positive rate.

But i...

MONDAY, Jan. 7, 2019 (HealthDay News) -- CT scans diagnose many serious conditions and illnesses, but they expose patients to levels of radiation that aren't always consistent and may be harmful, a new study finds.

The large differences in the doses of radiation patients are exposed to appear to be caused by who is doing the scanning and not differences in patients or equipment, resea...

MONDAY, Jan. 7, 2019 (HealthDay News) -- Higher costs, not better patient care, explain why the United States spends much more on health care than other developed countries, a new study indicates.

U.S. health care spending was $9,892 per person in 2016. That was about 25 percent more than second-place Switzerland's $7,919 and more than twice as high as Canada's $4,753, researchers fou...

MONDAY, Nov. 12, 2018 (HealthDay News) -- People who have experienced either a concussion or a mild traumatic brain injury are twice as likely to commit suicide than others, a new review suggests.

The analysis also indicates that men and women who have had a concussion are also more likely to consider or attempt suicide.

The investigators stressed that the absolute risk of s...

THURSDAY, July 12, 2018 (HealthDay News) -- The underpinnings of autism may lie in an unexpected part of the brain, a small study suggests.

Scientists conducted brain scans on 20 boys with autism and 18 boys without the neurodevelopmental disorder. The scans showed that boys with autism had a significantly flatter surface on the right side of their cerebellum. That side happens to be ...

WEDNESDAY, Feb. 14, 2018 (HealthDay News) -- The first blood test to help diagnose a concussion has been approved by the U.S. Food and Drug Administration.

Known as the Banyan Brain Trauma Indicator, it could help reduce the need for CT scans and thus decrease radiation exposure to patients, according to the FDA.

The blood test checks for levels of specific proteins that hav...

TUESDAY, Feb. 13, 2018 (HealthDay News) -- Before they go in for an X-ray, CT scan or MRI, patients may have questions about their screening. But new research finds at least one in every five people saying they received no information about their procedures beforehand.

"This is an important finding in today's health care system, where we want more patient engagement and involvement," ...

TUESDAY, Feb. 13, 2018 (HealthDay News) -- Kidney stones are becoming more common, especially in women, new research has found.

Better diagnostic tools could be part of the reason for the steady rise in diagnoses, according to Mayo Clinic researchers.

By using CT scans, "we are now diagnosing symptomatic kidney stones that previously would have gone undiagnosed because they ...

WEDNESDAY, Nov. 15, 2017 (HealthDay News) -- ER doctors frequently use pricey but unnecessary tests to determine whether people with chest pain are having a heart attack, a new study reveals.

Results show that patients don't do any better when CT scans or treadmill stress tests are tacked onto the standard battery of diagnostic tests for chest pain patients.

"You don't need ...
