Most people feel like they already know the basics about cancer.
Don’t smoke. Be sun safe. Eat well.
What’s changing is not the advice itself, but who cancer is affecting and how early it’s being picked up.
Recent reporting, including the Four Corners program, Cancer Generation, highlights a rise in diagnoses among Australians in their 30s and 40s. For many, it is not coming from one obvious cause, but a mix of factors that build over time.
That shift is why awareness is starting to focus less on broad rules, and more on noticing smaller changes earlier.

What cancer actually is
Cancer begins when some cells in the body stop following the usual pattern.
Instead of growing, dividing and stopping at the right time, they continue to grow and can form a mass or spread.
Some cancers develop slowly, while others move more quickly.
That difference is why noticing change early can make a real difference in how something is managed.
What newer research is pointing to
There is growing interest in how modern routines may influence cancer risk over time.
Researchers are looking at patterns such as:
Long stretches of sitting with little movement
Sitting for extended periods can affect how the body regulates blood sugar, hormones and inflammation. Over time, this may influence how cells grow and repair, particularly if it becomes a daily pattern.
Irregular sleep cycles
Disrupted sleep can affect the body’s internal clock, which helps regulate hormones and immune function. These systems play a role in how the body detects and responds to abnormal cell changes.
Higher alcohol intake across the week
Alcohol is processed by the liver into substances that can damage cells. Regular intake, even at moderate levels, can increase exposure over time, particularly when spread consistently across the week.
Cumulative sun exposure from outdoor lifestyles
In areas like the Redlands, regular time outdoors adds up over years. Even without sunburn, repeated exposure can lead to skin changes that may not be obvious without monitoring.
In May, events like Australia’s Biggest Morning Tea continue to support research into these patterns and improve understanding of how cancer develops.
At the end of May, World No Tobacco Day highlights the ongoing link between smoking and cancer risk. Stopping smoking, and never taking it up in the first place, remains one of the most effective ways to lower long-term risk.

Signs that are easy to overlook
Most changes people notice are harmless, but a few are worth checking rather than waiting.
For example:
- a lump that does not settle after a few weeks, especially if it continues to grow
- a sore or patch of skin that does not heal
- a mole that changes in colour, shape or size
- ongoing fatigue that feels different from your usual tiredness
- changes in bowel habits that persist
These are not automatically serious, but are worth having assessed if they do not return to normal.

Why finding changes early matters
When changes are picked up early, there are usually more options available.
This can mean simpler treatment, shorter recovery times, and in some cases avoiding more complex procedures.
In Queensland, where skin cancer is common, checks such as skin cancer screening and Total Body Mapping (TBM) can help identify changes that are difficult to track on your own.
When to get something checked
If something is new, not settling, or feels different from what you would expect for your body, it is worth having it looked at.
At Sunstate Family Practice in Victoria Point, patients from across the Redlands can book appointments for skin checks that include Total Body Mapping (TBM), general health reviews and ongoing monitoring.
Often, it’s just about confirming that everything is fine.
