Advances in breast cancer research have led to more personalized treatments, based on subtyping and more sophisticated testing. A risk assessment test can predict that some women do not need chemotherapy but will benefit from hormone therapy, and who might benefit more from both treatments.
In the last decade, overall rates of colorectal cancer have been falling among the general population in the US. However, African Americans are more likely to develop colorectal cancer at younger ages, and to die from it. The reasons for this disparity are unclear, but they are rooted in socioeconomic and racial inequities.
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 has updated its 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.
