A mum says her two-year-old daughter has 'hit rock bottom' in her fight against an aggressive form of blood cancer.

Brave Chloe, two, was diagnosed with Acute Lymphoblastic Leukaemia in early June after she developed what was believed to be a cold.

Mum-of-three Virginia Carpenter from Melbourne says the diagnosis was like 'being sucked through a vortex'.

Ms Carpenter told Yahoo News Australia : "It was pretty shocking. I felt like I was being sucked through a vortex.

"It’s a bit sickening."

The family have been assured the disease is treatable but Chloe will have to have treatment until the end of 2022.

The 41-year-old midwife added: "She’s hit rock bottom now after months of intensive treatments."

Chloe, who has a twin sister called Nina, has had 10 coronavirus tests in three months after repeatedly suffering high temperatures.

Ms Carpenter and her partner, Adrien, have been unable to take Nina to see her sister in hospital because of coronavirus restrictions.

The mum says Nina misses her sister terribly.

The toddler had several tests which confirmed her diagnosis

A gofundme page has been set up to help the family.

An update posted today says: "We’ve, I mean Chloé, has finished her second big phase of treatment for ALL.

"But after 3 plus months of intensive chemotherapy, some toxicity and one anaphylactic episode to one of the medications, it all caught up with her.

Chloe needed to have a blood transfusion on this day

"Kids can be so resilient and not show many signs of feeling unwell until they are really unwell. Chloé had to start feeds through her nasogastric tube because she’s not eating. And decided to spike a temperature and keep it that way for 5 days.

"A CT scan under a GA showed no sign of infection....phew. Relieved to say the least. And the temperature resolved. Neutropenia will do that.

"Another blood transfusion. Now we wait. We need to see an increase in Chloé’s neutrophils (bacteria fighting cells) before we can be discharged home.

"Then we can start all over again with the next phase of treatment, which I’m told is easier on Chloé and us as a family.

"Thank you again to the incredible nurses and oncology team at the RCH."
