Many studies have explored the relationship between hair dye use and risk of cancer or cancer-related death, with conflicting findings. In a recent study, researchers analyzed survey data from over 117,000 women collected over several decades regarding hair dye use and overall cancer risk.
With increased rates of diagnosis of very early breast cancer known as ductal carcinoma in situ, there has been controversy about treatment. A recent study found that having DCIS increased the risk of invasive breast cancer later, and also that women who chose more intensive treatment early were less likely to have invasive breast cancer.
Screening for colorectal cancer can lower mortality, but it varies in effectiveness and is not always possible to perform, so alternatives are needed. Researchers analyzing studies found evidence for regular use of low-dose aspirin, leading the US Preventive Services Task Force to recommend it for some people.
Over the years, the list of aspirin’s potential benefits has grown: a number of studies suggest that taking aspirin regularly can lower the risk of certain types of cancer. Now recent studies suggest that aspirin may also reduce the risk of breast cancer.
The US Preventive Services Task Force is recommending a change to its existing lung cancer screening guidelines, to open up the screening to a wider range of people based on their age and smoking history, with the goal of detecting more cancers and reducing deaths.
Most people understand the risks of sun exposure, even if they do not regularly wear sunscreen, but getting younger people to pay attention to this concern can be difficult. A study chose a novel approach to this problem by appealing to teenagers’ vanity and focus on their appearance.
Tinted sunscreens offer all the benefits of traditional sun protection products, plus they have added pigments that give them the ability to block visible light, which can also be harmful to the skin.
Good news on health –– which seems hard to come by right now –– includes declines in the rates of six out of 10 major causes of death in the United States.
A study of older adults found that those who had had more sexual partners were more likely to have developed cancer, but that does not mean there is a causal connection, and there are many ways that sexual behavior can affect cancer risk.
Not a fan of running? Good news: You don’t need to run fast, far, or that often to reap benefits. And you can ease into running by doing a run/walk program, where you alternate periods of running and walking and gradually increase the time spent running.
