The chemicals in sunscreens help shield people from the sun's rays, but they are also absorbed into the body at levels that raise some safety questions, a new study confirms.
The study, by the U.S. Food and Drug Administration (FDA), is a follow-up to a 2019 investigation. Both reached the same conclusion: The active ingredients in popular sunscreens can be absorbed into the blood at ...
A 29% drop in U.S. cancer deaths between 1991 and 2017 was driven by declines in deaths from four major cancers -- lung, colon, breast and prostate, according to the latest American Cancer Society (ACS) annual report.
Cancer deaths in the United States fell 2.2% between 2016 and 2017, the largest-ever single-year decrease.
Weight-loss surgery does more than shed pounds: new research suggests it might also lower your risk for skin cancer.
"This provides further evidence for a connection between obesity and malignant skin cancer, and for the view that we should regard obesity as a risk factor for these forms of cancer," said investigator Magdalena Taube. She's a researcher in molecular and clinical medici...
Former U.S. President Jimmy Carter is recovering in a Georgia hospital after he broke his pelvis in a fall at his home on Monday night.
"He has been admitted to Phoebe Sumter Medical Center for observation and treatment of a minor pelvic fracture," said a statement issued early Tuesday by The Carter Center. "He is in good spirits and is looking forward to recovering at home."
Melanoma is the most lethal type of skin cancer, and a new study finds that the diagnosis of a suspect lesion gains accuracy when a specialist pathologist is brought on board.
Many patients with melanoma are first diagnosed by general practitioners, dermatologists or plastic surgeons. A biopsy sample of the suspect lesion might then be sent to a general pathologist for further diagnos...
Wondering if you can do more than slap on some sunscreen to prevent skin cancer? A new study suggests that getting more vitamin A may help.
The study of around 125,000 Americans found that people with the highest intake of vitamin A lowered their risk of squamous cell skin cancer by around 15%. Most of the vitamin A they consumed came from foods.
Monitoring a melanoma patient's progress is challenging. But a laser-based test might allow doctors to quickly screen the patient's blood to spot tumor cells roaming the body, a preliminary study suggests.
Those cells, known as circulating tumor cells, are "shed" from the original cancer site into the blood vessels or lymph system. They are considered a potential red flag. They could ...
Interest in homemade sunscreens is hot, but many of these do-it-yourself brews lack effective sun protection, a new study warns.
Researchers found that only about one-third of homemade sunscreens on the popular information-sharing website Pinterest specified how much sun protection factor (SPF) each "natural" sunblock contained. In some cases, SPF content dipped as low as 2 -- far bel...
For years, you've been urged to slather on sunscreen before venturing outdoors. But new U.S. Food and Drug Administration data reveals chemicals in sunscreens are absorbed into the human body at levels high enough to raise concerns about potentially toxic effects.
Bloodstream levels of four sunscreen chemicals increased dramatically after test subjects applied spray, lotion and cream...
A healthy diet may trigger a better response to a certain kind of melanoma treatment.
New research suggests that a diet that's full of fiber appears to lead to more diverse intestinal bacteria (microbiome). In turn, a thriving gut microbiome is linked to a stronger response to an immune therapy for the aggressive skin cancer.
For people with the deadly skin cancer melanoma, one dose of the drug Keytruda before surgery might stop the cancer in its tracks, according to a groundbreaking new study.
Keytruda (pembrolizumab) is a PD-1 inhibitor, an immunotherapy drug that triggers the body's immune response to attack cancer cells. According to results of this study, the drug's effects peak as early as seven days...
A combination of two drugs that work with the immune system can help beat back melanoma that has moved to the brain, an early clinical trial has found.
The study included 94 patients with advanced melanoma that had invaded the brain. All were treated with two "immunotherapy" drugs -- Opdivo (nivolumab) and Yervoy (ipilimumab) -- which help the immune system find and destroy tumors.
Poverty is a major reason black and Hispanic children with some types of cancer have lower survival rates than white patients, a new study finds.
Researchers examined U.S. government data on nearly 32,000 black, Hispanic and white children who were diagnosed with cancer between 2000 and 2011. For several cancers, whites were much more likely to survive than blacks and Hispanics.
Organ transplant recipients are at increased risk for skin cancer and need to protect themselves, a dermatologist warns.
"Individuals who receive organ transplants need to take immunosuppressive medications for the rest of their lives, and this makes it more difficult for their bodies to fight disease, including skin cancer," said Dr. Christina Lee Chung. She is former director of th...
Stick or spray-on sunscreens are essential tools against skin cancer, but it's important to use them the right way, a dermatologist says.
"Sticks are easy for under the eyes and the backs of the hands, while spray sunscreens are often easier to apply on children," Dr. Debra Wattenberg said in an American Academy of Dermatology news release.
Flight attendants may face higher-than-average risks of breast and skin cancers, a new study finds -- though the reasons why aren't yet clear.
Harvard researchers found that compared with women in the general U.S. population, female flight attendants had a 51 percent higher rate of breast cancer. Meanwhile, their rates of melanoma and non-melanoma skin cancers were about two to four t...
If you could protect yourself from cancer, you'd do it, right? Yet most Americans still aren't taking the easiest step to prevent the most commonly diagnosed type -- skin cancer, which will affect one in five people at some point in their lives.
Only 14 percent of American men and 30 percent of women regularly use sunscreen when outside for more than an hour, according to a report fro...
Summer sun brings childhood fun, but experts warn it also brings skin cancer dangers, even for kids.
"Don't assume children cannot get skin cancer because of their age," said Dr. Alberto Pappo, director of the solid tumor division at St. Jude Children's Research Hospital in Memphis, Tenn. "Unlike other cancers, the conventional melanoma that we see mostly in adolescents behaves the sa...
For U.S. military personnel, deployment carries many dangers. And besides the well-known threats they face, these men and women are also at a higher-than-average risk for skin cancer, including potentially deadly melanoma, a new research review suggests.
Two military groups face a particularly high risk: white service members and men over 50, according to the report.
Construction workers, farmers and others who work in the sun are at greater risk for skin cancer, according to researchers. And a new study reveals these job-related cancers cost nations millions in medical expenses.
The researchers said lawmakers should address this trend and take steps to reduce job-related exposure to the sun's harmful ultraviolet rays.
