Singer and actress Christine Anu has joined the National Lung Cancer Screening Program's 'It's Good to Know' campaign as an ambassador, bringing a deeply personal message to Australians at risk of lung cancer.

Having experienced the impact of lung cancer on her own family, the Torres Strait Islander woman has determined to ensure other families don't face the same heartbreak, particularly when early detection couldL make all the difference.

Ms Anu lost her aunt to lung cancer, which showed her "just how devastating this disease can be".

"Too many lives are being lost because it often goes unnoticed until it's too late, that's the heartbreak I've seen in my own family," Ms Anu said.

"It's Good to Know that screening can detect lung cancer early, even before symptoms appear, because it gives families a chance to avoid the heartbreak mine went through."

The National Lung Cancer Screening Program (NLCSP) is the first screening program launched in Australia in almost 20 years.

It aims to reduce deaths and illness through early detection of lung cancer, which is Australia's leading cause of cancer-related deaths.

The NLCSP says more than 15,000 Australians are diagnosed with lung cancer each year with the current mortality rate at 27 per cent.

However when caught early, according to the NLCSP, more than 65 per cent of lung cancers can be successfully treated, which is why the Australian Government invested in this new screening program.

"This program is here for eligible Australians at risk, without judgement - it's about hope, families, and giving people the best chance to live a full life," Ms Anu said.

"And it's so important Aboriginal and Torres Strait Islander people feel this program is for them too, and that their health stories matter. If lung screening had been available earlier, my aunt might still be here today."

Ms Anu's message comes as the National Lung Cancer Screening Program gains momentum.

Since launching last July, the program has seen strong engagement, with 37,502 people enrolling - an average of 276 participants every day.

To date, more than 33,800 scans have been completed, leading to 389 individuals being referred for further investigation and potentially life-saving treatment.

The NLCSP says the uptake reflects growing awareness that early detection saves lives, offering hope for a disease that remains Australia's leading cancer killer.

Members of the public can access the screening program if they are aged 50 to 70 years, smoke tobacco cigarettes or have quit in the last 10 years, have no signs or symptoms of lung cancer, and have a smoking history of 30 pack-years (a doctor or healthcare provider will help determine this).

The It's Good to Know campaign is supported by the Australian Government and is being delivered in partnership with community organisations representing disproportionally affected people including Cancer Council Victoria, The Daffodil Centre, National Aboriginal Community

Controlled Health Organisation (NACCHO), Australian Multicultural Health Collaborative, ACON and the Royal Flying Doctors Service South Eastern section.
