3D mammograms may be useful in investigating abnormalities, but as a means of routine screening, they may do more harm than good.
3D mammography is becoming more widely available, but is it superior to the traditional 2D technology for breast cancer detection? The answer isn't clear-cut.

Russia appears to have developed a revolutionary mini-reactor able to power a missile.
Outside Earth’s protective atmosphere, there is nothing to shield astronauts from the dangerous cosmic radiation of space.
Space missions are dangerous. But when it comes to long missions, radiation may be the greatest threat to astronauts' health.
The scientific consensus is that 5G doesn’t pose a danger to our health.
Should we be concerned about the health effects of 5G? The short answer is no – there's no substantiated evidence that the electromagnetic energy used by mobile telecommunications causes harm.

New research shows the risk of lung cancer slowly increases five to 10 years after a breast radiation treatment; a form of brachytherapy developed in Canada is the safest treatment to reduce this risk.
New research reveals the risks of lung cancer after breast cancer radiotherapy and identifies the best treatment to reduce these risks.
Medical imaging such as MRI can seem daunting, and perhaps even a little sci-fi.
There are many different types of medical imaging and they all pick up different things.
