Late cancer detection puts Qlders at risk

More than half of all breast cancer cases in Queensland aren't diagnosed until the disease has already grown or spread, research shows.

Data from the Cancer Council Queensland (CCQ) show that 52 per cent of cases are only picked up at an advanced stage, significantly reducing the chances of survival.

The CCQ also found 45 per cent of people with bowel cancer weren't diagnosed until the disease was in the advanced stages.

CCQ spokeswoman Katie Clift said the results were alarming, further emphasising the importance of regular check-ups.

"Early diagnosis means that the cancer is less likely to have spread, making it easier to treat and improving a person's chance of survival," she said.

"All Queenslanders should get to know their own skin."

CCQ recommends women between 50-69 have a mammogram every two years, while women of all ages should self-assess and report any abnormalities to their doctor.

Breast cancer is the second most common cause of cancer-related deaths in Australian women after lung cancer.

Three in four women diagnosed in Queensland are aged over 50.
