Prime Minister Scott Morrison's wife Jenny has begged Australian women to look after their health and get checked for cancer.

"Women are putting off their health checks, pap tests, mole checks, mammograms and so much more,” the former nurse said sitting in Kirribilli House alongside family dog, Buddy.

"This week is Women’s Health Week, and it’s a chance for women across Australia to remind themselves about getting up-to-date with all of those tests and their health.”

"So call the doctor. Book that appointment. Don’t let it be the year where we say 'I’ll put that off'.

"Because your health is so important to you and those around you.’

She explained that doctor rates and test rates have dramatically fallen due to the coronavirus pandemic.

"During this time we’ve all been trying to do the right thing," she said.

"We’re wearing our masks, we’re washing our hands and maintaining our distance to keep ourselves and others healthy.

"But there’s some things that we might have put off that are really important as women. And that’s something we all need to pay attention to."

Experts are worried that there will be an increase in advanced cancer diagnosis due to people not getting tested during the pandemic.

"In Australia we are lucky to have such great screening processes - but there is a concern there will be many undiagnosed cancer cases due to the pandemic," Morrison said.
