Revealed: How your suburb can determine your risk of cancer

New research reveals where you live in Sydney could help determine your risk of being diagnosed with cancer.

The research, by NSW Cancer Institute, shows women in more affluent suburbs are more likely to get breast cancer while people in Sydney's west and southwest are more likely to develop lung cancer.

Professor David Currow from NSW Cancer Institute said a privileged life can also lead to the disease.

"I think many people are surprised by the fact an affluent lifestyle increases the risk of breast cancer," he said.

Working women keeping healthy and delaying having children can boost the level of estrogen in their bodies, in turn increasing the risk of cancer, 7 News reported.

In Sydney, the most breast cancer cases will be diagnosed in Mosman, Woollahra and Lane Cove while bowel cancer was the highest in the Hawkesbury, Penrith and Bayside areas.

More people will suffer lung cancer in Campbelltown, Penrith and Blacktown than anywhere else and melanoma is the highest in the Sutherland Shire, Mosman and Wollondilly.

One person said when listening to the statistics, "it's quite scary".

"It's a higher economic group and I thought it would be healthier and wealthier and wiser," another person told 7 News.

New research shows this year, it's expected more than 46,000 people in New South Wales will be told they have cancer.

No matter what part of the city someone lives in, it's important everyone has access to equal treatment.

The cancer institute says people New South Wales are lucky to have advanced treatments with some of the most successful survival rates in the world.

The advice is to get regular check ups, regardless of your postcode.
