MONDAY, Oct. 18, 2021 (HealthDay News) -- Researchers may have found a noninvasive way to temporarily open the brain's borders to allow tumor-fighting medication inside.
By necessity, the brain is shielded by a layer of specialized cells called the blood-brain barrier. Its job is to allow needed substances in -- like oxygen and sugar -- while keeping out substances that...
Just over a decade ago, the passage of the Affordable Care Act (ACA, or Obamacare) made many common cancer screenings free. But a pair of new studies caution that when those free tests turn up signs of trouble, important follow-up tests may be too pricey for some patients.
The bigger concern: Some patients may forgo these expensive tests, even when they may prove lifesaving.
Equal access to the most effective drugs helps eliminate the survival disparity between Black and white lung cancer patients in the United States, a new study shows.
In general, Black lung cancer patients are more likely to die than white patients, but these findings suggest that barriers to care are the main cause of racial disparities in lung cancer survival rates, the researchers said....
When Hispanic people get a skin cancer diagnosis, their tumors are about 17% larger than those of white people, researchers say.
According to the American Academy of Dermatology (AAD), skin cancer is often diagnosed at a more advanced stage in people with black and brown skin, leading to worse results. This makes it especially important to know the signs of skin cancer.
In yet another illustration of how the pandemic wreaked havoc on medical care, a new report shows that 15% of adult cancer patients worldwide didn't get potentially lifesaving surgery due to COVID-19 lockdowns.
"Our research reveals the collateral impact of lockdowns on patients awaiting cancer surgery during the pandemic. Whilst lockdowns are critical to saving lives and reducing the spr...
Black kids and Hispanic kids with cancer fare worse than their white counterparts, a large, nationwide study finds.
"This study suggests that improving health insurance coverage and access to care for children, especially those with low [socioeconomic status], may reduce racial/ethnic survival disparities," Jingxuan Zhao, an associate scientist at the American Cancer Society in Atlanta, a...
There's some encouraging news for people who develop lung cancer even though they've never smoked.
Precision drugs already approved by the U.S. Food and Drug Administration can be used to treat 78% to 92% of their tumors, a new study reports. These precision drugs target specific mutations in tumors.
Most never-smokers' lung tumors have so-called driver mutations, specific mistakes...
A pair of experimental tests could help doctors detect colon or prostate cancer with just a sample of blood or saliva.
One test examines a person's blood for four biomarkers linked to inflammation. In a small study, it outperformed the fecal blood test now used in colon cancer screening, said lead researcher Dr. Mona Eldeeb, of Alexandria University Medical Research Institute in Egypt.
The cancer drug cisplatin can save children's lives, but often with the side effect of hearing loss. Now a new study shows that young children are especially vulnerable, and the hearing damage may begin early in the course of treatment.
The researchers said the findings highlight the need to screen kids' hearing during each round of cisplatin treatment, to catch problems early.
If you have cancer and you think coronavirus vaccines may do you little good, don't let your hesitation stop you from getting the shots: A pair of clinical trials finds that patients' immune systems ramped up after vaccination.
The findings were presented this week during a virtual meeting of the European Society for Medical Oncology (ESMO Congress 2021).
An artificial intelligence tool could help radiologists spot breast cancer on ultrasound images and reduce the need for extra testing, new research suggests.
"Our study demonstrates how artificial intelligence can help radiologists reading breast ultrasound exams to reveal only those that show real signs of breast cancer, and to avoid verification by biopsy in cases that turn out to be be...
There's good news for health-conscious sausage and bacon lovers.
A new study suggests the Japanese knotweed plant could be used to make healthier cured meats.
According to researchers, this fast-growing plant that invades gardens and buildings contains a chemical that could take the place of the preservative nitrite, which has been linked to cancer, in cured meats. That might not on...
Hispanic people in the United States have lower cancer rates than white people, but they are much more likely to develop certain preventable cancers.
"The good news is that overall cancer rates are lower in Hispanic people, but we are seeing very high rates of infectious disease-related cancers, many of which are potentially avoidable," said study author Kimberly Miller, a scientist at th...
Liver cancer is on the rise in rural America, but on a downswing in cities, new research shows.
Hepatocellular carcinoma (HCC) is the most common type of liver cancer and the fastest-growing cause of cancer deaths in the United States. It's rising at an annual rate of nearly 6% in rural areas, approaching rates seen in cities, the study authors found.
New research offers good news for women with an aggressive HER2-positive breast cancer.
A targeted therapy, trastuzumab deruxtecan (T-DXd), sold as Enhertu, triples the length of time that the cancer remains in check when compared with the current gold standard, trastuzumab emtansine (T-DM1).
Both of these drugs are second-line treatment options for HER2-positive breast cancer that...
Pfizer is expanding the recall of its anti-smoking drug Chantix (varenicline), the company announced Friday.
The nationwide recall of all Chantix 0.5 mg and 1 mg tablets was prompted because they may contain levels of a nitrosamine, N-nitroso-varenicline, that are at or above levels approved by the U.S. Food and Drug Administration.
Long-term ingestion of N-nitroso-varenicline may b...
Radiologists still outperform artificial intelligence (AI) when it comes to breast cancer screening, a new paper shows.
Many countries have mammography screening programs to detect and treat breast cancer early. However, examining mammograms for early signs of cancer means a lot of repetitive work for radiologists, which can result in some cancers being missed, the authors explained.
Here's another reason to avoid unnecessary use of antibiotics: Long-term use of these medications could increase your risk of colon cancer, researchers say.
"While in many cases antibiotic therapy is necessary and saves lives, in the event of less serious ailments that can be expected to heal anyway, caution should be exercised. Above all to prevent bacteria from developing resistance but...
A recall of more than a dozen types of Philips breathing machines because of potential cancer risks has millions of Americans struggling to find replacements to deal with sleep disorders, breathing problems and respiratory emergencies.
The recall involves certain Respironics BiPAP (bi-level positive air pressure), CPAP (continuous positive air pressure) and ventilator machines made before...
As legal use of marijuana expands, experts say U.S. cancer patients are still far less likely to use it than the general population.
That's the key finding from a new study based on data on smoking habits -- both tobacco and pot -- collected from nearly 20,000 people between 2013 and 2018. Several U.S. states legalized recreational pot during that time.
Immunotherapy helped extend the lives of some patients with the most common type of advanced colon cancer, researchers report.
The new findings are important, they noted, because immunotherapy doesn't typically work against microsatellite stable (MSS) colon cancer. These patients have few treatment options once their disease no longer responds to chemotherapy.
Significant fatigue at the start of cancer treatment is associated with a greater risk of severe side effects and shorter survival, a new study finds.
Researchers analyzed data from four clinical trials of lung cancer or prostate cancer treatments that were conducted by the SWOG Cancer Research Network, a cancer clinical trials group funded by the U.S. National Cancer Institute.
An experimental gel has shown early promise in treating the most common form of skin cancer -- hinting at a potential alternative to surgery in the future.
Researchers tested the gel in 30 patients with basal cell carcinoma (BCC), a skin cancer diagnosed in more than 3 million Americans each year. The tumors rarely spread and are highly curable, usually through surgical removal.
The pandemic widely disrupted medical care across the United States, but a new study reports that clinical trials testing cancer treatments were able to carry on.
Researchers found that U.S. cancer trials quickly responded to the pandemic in the early months, allowing the studies to get back on track after an initial -- and steep -- drop-off in patient participation.
Sun protection is essential as you enjoy the outdoors this summer, a skin expert stresses.
"Skin cancer is the most common cancer in humans so it's important that we do what we can to protect ourselves," Dr. Ida Orengo, a professor of dermatology at Baylor College of Medicine in Houston, said in a school news release.
Black men in the United States have higher rates of prostate cancer than white men, yet they were far less likely to have surgery for their cancer during the first wave of the COVID-19 pandemic, a new study finds.
Researchers analyzed data from a Pennsylvania urologic database to compare prostate removal (prostatectomy) rates among Black and white patients who had untreated prostate cance...
