The genetic code of two of the most deadly cancers has been cracked by British scientists in a world first that opens up a whole new era in the treatment for the disease.
All the mutations that turn healthy cells cancerous in both lung and skin tumours have been identified in what researchers described as a "transforming moment" in the search for preventions, treatments and cures for both terminal illnesses.
High levels of a hormone that controls appetite appear to be linked to a reduced risk of developing Alzheimer's disease, US research suggests.
The 12-year-study of 200 volunteers found those with the lowest levels of leptin were more likely to develop the disease than those with the highest. The JAMA study builds on work that links low leptin levels to the brain plaques found in Alzheimer's patients.
Researchers presented new findings Saturday at a breast-cancer symposium here suggesting that the risks associated with anthracyclines, a class of chemotherapy drugs widely used to treat the disease, outweighed their benefits in some patients.
Here's how it's happening:
Tobacco use kills at least 5 million people every year, a figure that could rise if countries don't take stronger measures to combat smoking, the World Health Organization said Wednesday.
The Food and Drug Administration said some patients received up to eight times the normal amount of radiation. High doses of radiation can cause cataracts and increase the risk of some forms of cancer.
In October, the FDA said it was investigating 206 cases of patients being overexposed to radiation during CT perfusion scans of the brain at Cedars-Sinai Medical Center in Los Angeles during an 18-month period.
Imagine being watched by two undercover cops as you engage in an illicit deal in a deserted parking lot. The buyer hesitantly hands you some cash. You flash a look over your shoulder, just to make sure the coast is clear, then you hand over the contraband. Neither of you says a word. You just nod, acknowledging the deal is done, then you head back to your car and buckle up for the drive home.
