A lot of people have spent a very long time wondering what causes cancer – and scientists still can’t say for certain why an individual person might have it.

I have worked on this problem for many years, and to be honest it still blows my mind to really think about just how complex it is.
The science isn’t clear on whether organic foods can lower your risk of cancer. But eating plenty of fruit and veg – however it’s grown – can reduce your risk.
The participants who chose more organically grown foods over 4.5 years had slightly lower rates of cancer. But it doesn't necessarily mean one thing caused the other.
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.
A California judge ruled coffee should carry a cancer warning label but the evidence says something very different.
Many men who have prostate cancer will die with it, rather than of it.
Since the 1980s, PSA tests have been used for the diagnosis and follow-up of prostate cancer. However, its use as a screening test for prostate cancer remains controversial.
People who are unable to tan and who have moles on their skin are among those at heightened risk of developing melanoma.
Australians over the age of 40 can now calculate their risk of developing melanoma with a new online test.
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.
Different people have very different chances of being diagnosed with breast cancer.
There is usually no one factor that causes breast cancer. It's likely a combination of the effects of a person's risks combined with an element of bad luck.
Bladder cancer has a lower profile compared to other types of cancer such as breast, lung and prostate.
Timely and appropriate investigation of suspicious symptoms, especially blood in the urine, is crucial for the accurate and early diagnosis of bladder cancer.
Physical activity has long been considered a way to lower risk for breast cancer.
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.
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.
Most common childhood cancers are leukemia and Hodgkin lymphoma.
Most children who have cancer live in the developing world where their survival rate is less than 25%. In Kenya awareness about childhood cancer is low and treatment isn't always readily available.
Sen. John McCain (R-Ariz.) returned to the Capitol July 25 to cast what was a tie-breaking vote to proceed to debate a bill to repeal Obamacare.

A diagnosis of glioblastoma did not keep John McCain from the Capitol to cast a crucial vote that could end Obamacare. His actions are a reminder that stats are one thing but human beings, another.

Two US researchers have traced the majority of cancers to DNA replication errors during our natural cell replacement. Their finding asks for a renewed inquiry into the role of "chance" in cancer.
The incidence of liver cancer is increasing and has the potential to become a national health crisis.
While other cancer rates fall or remain static, liver cancer is on the rise. Here's why we need to start paying attention.
Captain, we’re being pummeled by cosmic rays!

The true radiation risk from commercial flying has nothing to do with security scans. A radiation expert explains how much cancer risk the most frequent of flyers take on when they take to the skies.
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.
