Cancer, by nature, is a destructive force. Sometimes, it spreads, or metastasizes, to a distant body part. While some cancer cells die during this process, others might go on to create additional tumors. Cancer's ability to spread throughout the body can turn a curable case into an aggressive and sometimes fatal one. A team of engineers and cancer biologists may have found a way to slow down, and even stop, the migration of breast cancer cells. The majority of treatments are ineffective at curing metastatic cancer, so it is vital to find ways to stop the cancer cells from spreading. Researchers believe electromagnetic fields can help. While this has been a point of interest for years, it is only recently that experts have begun to unravel the mechanism. A new study, published in Communications Biology, has found that these electromagnetic fields are effective in halting the spread of some breast cancer cells. The speed at which breast cancer migrates varies between individuals, and it is almost impossible for experts to calculate how and when cell mutations occur. What we showed, biologically, is that these cancer cells are becoming profoundly less metastatic, which is a very important finding.", says Jonathan Song. (credits: www.medicalnewstoday.com)

People with diabetes, particularly those with type 1 diabetes, may have an increased risk of hypoglycemia (low blood sugar) if they receive too much glucose lowering therapy. New research now warns that many people with diabetes face that risk. The researchers found that in the U.S., people with diabetes often receive much more medication than their hemoglobin A1C levels would require. Hemoglobin A1C levels are a person's average blood sugar levels over a period of around 3 months. In the cohort they studied, this resulted in 4,774 hospital admissions and 4,804 emergency department visits in the span of 2 years. According to the study, 32.3% of the 10.7 million people in the cohort had clinically complex profiles. However, this did not seem to have any bearing on whether or not an individual received intensive treatment for diabetes. "Older people and others we consider clinically complex are more at risk to develop hypoglycemia, as well as experience other adverse events because of intensive or overtreatment," says Dr. McCoy. "However, at the same time, these people are unlikely to benefit from intensive therapy rather than moderate glycemic control," she notes.
