Physical activity is considered an important way to lower risk for breast cancer. But what if your ability to be fit is influenced by genes you inherit? Would that raise your risk? In rats, it did.
October is breast cancer awareness month. Women should know there is no reliable evidence that routine mammograms reduce death from breast cancer, and there's good evidence that they cause harm.
Canadian insurance companies argue that a new law denying them access to genetic test results will raise the cost of insurance for everyone. That's doubtful.
A new study has found the alcohol industry deliberately misrepresenting the cancer risk of alcohol, while passing it off as health messaging.
Calls to routinely offer breast cancer screening to more women might sound like a good idea, but can harm. Here are three questions to ask when figuring out whether more screening really is better.
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.
Australian health-care organisations are urging action on treatments of people who don't need them.
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.
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 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.
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.
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.
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.
Obesity is one of the factors behind a large rise in cancer rates among women.
Not only are tumors are different from one another, but there can even be genetic differences within a single tumor.
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.
Until now, the processes that lead some girls to start developing before others have been poorly understood.
