Artificial light has transformed the night sky, a change researchers continue to link to health problems.

Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Some conditions should be classified as normal in some people and don’t need treatment.
Australian health-care organisations are urging action on treatments of people who don't need them.
The curse of survival.
A twinge can be all it takes to convince patients they have a new tumour
The high cost of cancer drugs in South Africa has come under the spotlight with an investigation by the Competition Commission in the country.
Digitized strand of DNA.
Genetic testing is revealing important information about disease risks, and consumers can now pay for a test to know their risk. They might be better off if their doctors considered these risks, too.
Women with breast cancer face many treatment decisions on the path to survivorship. One question has been: Can they have fewer doses of radiation and still keep their risks for recurrence low?
Women with breast cancer often have six weeks of radiation therapy after surgery to remove the cancer. A recent study suggests that shortening that time is not only effective but also cost-saving.
Scientists know that many toxins, such as those found in cigarettes, cause most lung cancers, whose cells are depicted here. But isolating causes for other cancers is an ongoing effort.
What causes cancer? A scary truth might be that we have created an environment for it. An anthropologist's search for answers to her own diagnosis raises questions for all of us.
Tumour evolution was first identified 40 years ago. We're finally making good progress with it.
We know obesity is bad for health - but most people don’t realise it’s implicated in causing many cancers.
Obesity is linked with a host of health outcomes. Both a disease itself and a risk factor linked to many others, we explore the linkages between obesity and cancer.
Cancer cells, in red, cannibalize a type of stem cell, shown in green. The red cells with small specks of green are breast cancer cells that have “eaten” the stem cell.
After treatment for breast cancer, many women receive the news that they are cancer-free. In many cases, the disease will come back. How and why does that happen? New findings offer an explanation.
Breast cancer is more common in overweight women.
Obesity is one of the factors behind a large rise in cancer rates among women.
There are genetic difference within and between tumors.

Not only are tumors are different from one another, but there can even be genetic differences within a single tumor.
Advances in breast cancer research in the last decade has introduced new treatment regimes.
The chances of surviving breast cancer are improving everyday due to advanced research and new treatment techniques.

The case of bovine leukemia virus shows how scientists monitor health risks in our food supply and why it's critical to revisit scientific conclusions when new technologies become available.
Where first is not best.
Until now, the processes that lead some girls to start developing before others have been poorly understood.
Doctors and patients should appreciate the many roles estrogens play in the body.

Estrogens also have many positive effects on mental health, cognitive function, libido and protection of the brain, possibly even slowing the onset of Alzheimer’s disease.
Many people with cancer feel ashamed and judged by others’ reactions.
People with cancer are exposed to many, often misrepresented, ideas about cancer. These can induce stress and even shame for the sufferer who might feel they've done something wrong.
A cancer patient from Inner Mongolia seeks treatment in Beijing.
Of women who die from cervical cancer, 87% live in poor countries.
It’s normal for breasts to be a little bit lumpy.
Women are told it's important to self-check their breasts. But is this true?
Woman receiving chemotherapy.
New tools help doctors and breast cancer patients decide whether chemotherapy is needed. A recent study suggested that many can forgo chemo. But the decision is complicated. Here's why.
