The use of radiation-based imaging has risen dramatically in the past decade, and medical radiation now accounts for a significant proportion of all radiation exposure in the United States. Critically ill patients are often subjected to many CT scans and x-rays, but who is keeping track of when enough is enough?
There are more than a million colon cancer survivors in the U.S. according to the American Cancer Society. That number is rising because doctors are finding and removing more precancerous polyps during colonoscopies.
Patients with metastatic melanoma have faced grim prospects: the American cancer society says the five-year survival rate is only 15 percent. That started changing when the FDA approved Keytruda in 2014. Despite the drug's success, 60 percent of patients didn't respond. Now researchers at UCLA hope that adding a second drug could cut that number in half.
Ovarian cancer is the most fatal gynecological cancer because it lacks early detection strategies. But something that's already sitting on your medicine cabinet shelf might be a step in the right direction for some women.
More than 50 percent of patients with colorectal cancer will develop liver metastases, and while the standard treatment is liver surgery, only one third of patients are candidates. Now a new protocol is opening the door for another option.
For years, older model, so-called legacy pacemakers were not compatible with MRIs because the metal in the pacemakers caused the magnetic resonance imaging devices to fail, lead tips to overheat, and caused discomfort in patients. Now, imaging experts have made adjustments so MRIs can be safe for more patients.
Almost half of all adults in the U.S. develop colon polyps during their lifetime, growths that are often benign, but sometimes develop into cancer. Now, one doctor at Mt. Sinai hospital in New York is advocating a procedure developed in Japan for removing and testing some of them.
