Each person’s unique gut microbiota composition is in continuous communication with the immune system.
The composition of bacteria in our gut regulates our immune system. Modifying it - through poo transplants for example - can control cancer risk, as well as response to treatment.
A study found children are at greater risk of developing later cancers from radiation from CT scans.
In a recent study of almost 11 million young Australians, we showed those exposed to a CT scan before the age of 20 had a small increase in cancer risk in the years after exposure.
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.
There’s no reason why more boys should be diagnosed than girls.

There's no good reason why diagnosis rates differ. And it may be down to gender discrimination.
Breast density appears white or bright on mammograms – so do breast cancers.
Women with dense breasts are more likely to develop breast cancer. Density also makes it harder for doctors to detect breast cancer on a mammogram.
But it’s unclear what that means for cancer risk.
Of the 49 inks tested, only four complied with the European standards. Carcinogens were found in more than one-fifth of the samples, and in 83% of the black inks.
People should not interpret the study as saying that every woman who has been overweight for some time in her life will develop cancer at some point.
UConn Rudd Center for Food Policy & Obesity
A longitudinal study featuring nearly 74,000 US women has found that the longer a woman has been overweight or obese during her adult life, the higher her risk of developing cancer.
Whether or not coffee causes cancer has been under question since 1991.
Scalding injury to body tissue is not known to cause cancer. But experimental data suggest cancer may arise when injured tissue then comes into contact with carcinogens.
After one reactor at the Chernobyl nuclear power plant caught fire and exploded in 1986, the whole site was encased in a concrete sarcophagus.
The meltdown at the Chernobyl Nuclear Power Plant in 1986 exposed 572 million people to radiation. No other nuclear accident holds a candle to that level of public health impact.
When the DNA repair tool is faulty or broken, cancer happens.
Lynch syndrome is a common, inherited condition that affects thousands of Australians and greatly increases their risk of developing cancer. Yet 95% of those who have it don't know about it.
Elementary school students about 13 miles from the Fukushima Daiichi nuclear power plant walk past a geiger counter in 2012.
Remediation will never get radiation to zero in the area affected by the 2011 meltdown at the Fukushima-Daiichi nuclear power plant. Rather than safety, the conversation should focus on acceptable risk.
This body map brings together evidence on proven cancer causes. Using credible, scientific sources it answers questions about whether alcohol, red meat or sun exposure increase your cancer risk.
What triggers cancers: bad luck or environment?

Two major studies have come to different conclusions – but there's much more to it than chance alone.
Different parts of the guayabano or soursop plant has cancer-fighting properties.
There are several natural remedies that have can help reduce cancer cells.
A report released by the World Health Organisation has ranked red meat as probably carcinogenic to humans, possibly causing bowel cancer.
The World Health Organisation's report on the increased cancer risk with eating processed and red meat has been met with mixed reactions.
Methods of communicating relative risk to the public are often confusing.
There are several ways scientists can explain risks of cancer and other diseases; some are easier to understand than others.
Consumption of chicken has been rising in Africa. This is a short-term solution to improving food insecurity.
Meat has health benefits. And good quality meat could also be the solution to the food insecurity problems that plague two-thirds of households in the developing world.
Eating two slices of bacon every day increases your risk of bowel cancer.
The World Health Organisation has determined that eating processed meat definitely causes cancer, while eating red meat probably does.
No, we’re not swimming around in a soup of cancer-causing chemicals.
Cancer is caused by a combination of genetic and environmental influences – a kind of genetic lottery where the odds are stacked by environmental and lifestyle factors.
More sleep is not necessarily better for long-term health.
Sleep is vital for good health but more may not always be better for everyone. In fact, a growing body of research shows that it may increase your risk of early mortality.
