Both obesity in general, and central obesity, are associated with a higher risk of some breast cancers, finds a new Chinese study. The strength of the association was affected by whether the tumors carried receptors for estrogen or progesterone.
It used to be that breast cancer diagnosis often meant a radical surgery, removing the breast as well as underlying muscle. But in the last few decades, we've learned that such extreme measures are usually not necessary. And recent research indicates that minimal surgery (along with radiation and systemic treatment) may be all that's necessary, in some cases.
A new study in JAMA Surgery reports that a crucial decision – whether a breast cancer patient should undergo a double mastectomy when only one breast is affected – is heavily influenced by her surgeon's recommendation.
Most Americans are rightly squeamish about forcing anyone to do anything against their will. But allowing homeless people to do whatever they want is no longer a viable solution. When a community fails to practice proper hygiene and sanitation, it becomes a ticking time bomb for infectious disease.
Even under the best of circumstances, the five-year survival rate for pancreatic adenocarcinoma is devastating. According to the American Cancer Society, for stage IA it's just 14%. And for stage III – a horrifying 3%. 
Colorectal cancer is the second-leading cause of cancer death in the U.S. Finding it early can vastly improve the chances for successful treatment, but screening rates are low, even though screening is known to be effective. But if people are reminded to be screened, or are sent in-home tests, the screening rates improve. 
New reports out of Australia contain some sobering news. The number of influenza cases this year is 2.5-times that of the same time period last year. Does this mean that the US is looking at a bad flu season? Probably yes, but there are many factors involved. Several experts explain. 
While for some women it's been a lifesaver, the utility of mammography screening for breast cancer has been a bone of contention since it's unpleasant and can be downright painful. One way to make it more bearable would to give women more control over the procedure – and the FDA recently approved a device to do just that.
Rapid, accurate detection of a tuberculosis infection still remains a healthcare challenge. Developing an assay that's able to definitively diagnose TB, and one that's cheap, should be high on our priority list. Especially, as we annually see increases in TB's prevalence.
The Food and Drug Administration has just approved a reformulation of amantadine for the treatment of Parkinson's Disease. It's a significant step forward.
There's good and bad cholesterol. And if we want to avoid certain types of heart and circulatory problems, we want to lower the bad, LDL and raise the good. But how high is enough? And is it possible to get the good, HDL too high? If the results of a recent study are confirmed, yes, having HDL that's too high won't help your heart.
Tularemia is caused by the bacterium Francisella tularensis. Because it naturally infects rabbits and rodents, there isn't much we can do to eradicate it. Roughly 125 Americans are diagnosed with tularemia annually.
