The cancer was detected during a recent screening, and doctors are optimistic about her prognosis due to the early detection, which is crucial for effective treatment.

Premier Chris Minns expressed his support for Car, describing her as a 'fighter' and emphasizing the importance of her health and recovery during this challenging time.

During her absence, fellow minister Courtney Houssos will temporarily take over Car's responsibilities as Minister for Education and Early Learning, as well as Minister for Western Sydney.

At just over 40 years old, Car is among several women politicians who have faced breast cancer while in office, following the example of federal MP Peta Murphy, who passed away from the disease in 2023.

Car has previously battled kidney cancer, but her current breast cancer diagnosis is confirmed to be unrelated to that earlier condition.

In a heartfelt social media video, Car requested the community's understanding as she prioritizes her health and family during this period of treatment.

Since being elected in 2015, Car has served as Deputy Premier since Labor's victory in March 2023, alongside her ministerial roles.

Before her political career, Car was a Penrith City councillor and worked as a national communications manager at MS Australia, among other roles.

Car expressed her determination to overcome this health challenge and looks forward to returning to her role in government.

Minns confirmed that Car will remain as Deputy Premier, with her level of involvement adjusted based on her treatment progress.

Car's leadership and commitment to her roles have been evident since her election, and her resilience is being supported by her colleagues during this time.

Prue Car, the Deputy Premier of New South Wales, has publicly announced her diagnosis of breast cancer and will be taking indefinite personal leave to undergo immediate treatment.
