Many cancer patients have chemotherapy after surgery, but not all of them actually need it.
We have no reliable way of knowing which patients' cancer will return after surgery, so often chemotherapy is given to mop up any remaining cancer cells that may have gone undetected.
What trends might emerge when we map cancer incidence and mortality rates across Australia?
It's clear that socioeconomic position has a strong influence on cancer incidence and mortality in Australia.
Colonoscopies are on the rise in Australia.
A colonoscopy is usually done to diagnose bowel cancer. It is an invasive procedure with risks such as bowel perforation. It's important to only have the test if you're likely to benefit.
We only know if a cancer has been cured in hindsight.

A cancer is in remission when it can no longer be detected. But we only say it's cured when it hasn't come back for a certain time – and that differs for different cancers.
Many people aren’t aware of the long-term risks alcohol poses to health.
The growing list of alcohol-related diseases includes bowel cancers, mouth and oesophageal cancers, breast cancers, heart disease, respiratory infections and mental health problems.
The researchers looked at cancer occurrence in those exposed to higher intakes of ultra-processed foods, compared to lower intakes.
The study showed that every 10% increase in consumption of ultra-processed food was linked to a 12% increase in developing some types of cancers. But it didn't show the processed food caused cancers.
Liquid biopsy is less invasive than standard biopsy, where a needle is put into a solid tumour to confirm a cancer diagnosis.
There are currently few effective and non-invasive methods to screen for early stages of cancer. But scientists have now developed a new blood test that promises to detect eight different cancers.
We’ve known for over three decades that cancer risk increases with alcohol consumption.
A new study has found the alcohol industry deliberately misrepresenting the cancer risk of alcohol, while passing it off as health messaging.
If you were destined for dementia in your 60s, but there was nothing you could do about it, would you want to know?
A test of all your genes for disease risk is not yet the precision diagnostic and treatment tool we hope it will one day be.
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.
I recently had a colonoscopy, an invasive medical procedure to examine the bowel, and was hugely relieved to get the all-clear. I posted a description of my experience to my friends on Facebook and got…
A bit of prosciutto as part of a well-balanced diet is not going to do you much harm.
Age-standardised cancer death rates have been falling in Australia.
Currently, seven cancer types are listed in the top 20 causes of death in Australia. These are cancers of the lung, blood and lymph, bowel, prostate, breast, pancreas, skin and some childhood cancers.
Nothing to be embarrassed about.
Too many people literally are dying of embarrassment.
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.
Relative risk is your risk compared to that of someone else.
Relative risk is the risk one group of people has of developing a cancer compared to the risk of another group.
The fry who came in from the cold.
Hold the cape and leggings. The dear old blood pudding has its merits, but it's far from perfect.
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.
Moderate intakes of red meat and alcohol can prevent a cancer diagnosis.
Nearly 40,000 cancers diagnosed in Australia can be prevented if people avoid known risk factors for the disease, according to research published today.
