Strict enforcement of radiation monitoring and procedural evaluations has led to a drastic reduction of South Korean healthcare workers' exposure to radiation over the past 10 years, according to government data published online in the Korea Herald.

A new study reinforces the expectation that cancer patients who postpone radiation therapy treatments will have poorer outcomes than those who fully comply with the program as scheduled. No surprise there, but the researchers also found that the differences are sharp, consistent across disease sites and observable despite eventual program completion by the stragglers.

Johns Hopkins researchers have begun genetically modifying adult cells to create balls of neurons that may serve as “mini-brains,” potentially good for preclinically studying—in petri dishes rather than in animals—Alzheimer’s, Parkinson’s, autism and the effects of drugs, for starters.

Men tend to think they’re at slim-to-zero risk of getting breast cancer. So when a man gets it—and the man is a cancer biologist, and he has a mastectomy, and he blogs about it to undeniably illuminating effect—that man is worth hearing from.

When it comes to predicting the cognitive-impairment course Alzheimer’s disease will take in a mildly stricken patient, neither of two tracers commonly used with PET—18F-FDG (for assessing glucose metabolism) and 11C-PiB (for assessing amyloid deposits)—brings much to the table. And that’s so regardless of automated vs. visual analysis.

Radiation therapy for post-lumpectomy patients 70 and older with small, hormone receptor-positive breast cancer should have significantly declined over the past 16 years, but it’s only dipped a bit.

Cigarette manufacturer Philip Morris USA does not have to pay for annual low-dose lung cancer CT screening for healthy smokers of Marlboro cigarettes, a Massachusetts federal jury has decided on Wednesday.

Ultrasound imaging using power Doppler signaling to assess damage and guide biopsy can help identify rheumatoid arthritis (RA) patients in remission who stand to benefit by getting off biologics, which suppress the immune system to considerable risk and can produce harsh side effects.
