Sarah Gandy has been diagnosed with breast cancer.

The former host of The Hits took to Instagram to share the news, saying she was diagnosed at the beginning of February.

The news comes after a tough end to 2018, when Gandy left her job at The Hits.

In her post, she said she was staying upbeat, and vowed to "kick its butt".

She wrote: "After a pretty weird end to 2018 I was looking forward to taking on some exciting new adventures in 2019 ... and boy has the universe delivered.

"I found a lump and had it checked in Jan, and then found myself playing the world's worst waiting game. The results came back and instead of balling my eyes out or going into shock, I somehow just went ok ... what's next? I've been business mode Gandy, crying mode Gandy, scared of needles mode Gandy and cracking bad jokes to doctors Gandy. I'm alive and I intend to keep it that way."

Oh life, you funny monkey🐒 After a pretty weird end to 2018 I was looking forward to taking on some exciting new adventures in 2019...and boy has the universe delivered ✨🙌🏻✨ At the start of Feb I was diagnosed with breast cancer. I found a lump and had it checked in Jan, and then found myself playing the world’s worst waiting game. The results came back and instead of balling my eyes out or going into shock, I somehow just went ok... what’s next? I’ve been business mode Gandy, crying mode Gandy, scared of needles mode Gandy and cracking bad jokes to doctors Gandy. I’m alive and I intend to keep it that way. I start my first round of chemo next week, and I tell ya, the boob ninjas are gonna be out kicking some serious boob cancer butt 🦹🏻‍♀️⚔️🍒 I’ve thought a lot about how and when to share this. One thing all my docs say is it’s amazing how many young women are now presenting with the old BC. So I figured, let’s not screw around here. LADIES OF ALL AGES!! Please please please check your boobs, and if you’re like “ummm maybe that’s something, or nah nah, it’s probs nothing” er on the side of something and go see your GP! Mammograms are not scary. If you do have cancer it’s ideal to find it and kick it’s ass before it has time to even get a look in. I’ve posted this picture as it’s about a week before all the cancer stuff kicked in, and I plan on having many more moments like this with my beautiful husband @mrlukehaigh 💕 I just hope he likes bald chicks 😳

Gandy also warned her followers not to muck around with breast cancer.

"Please please please check your boobs, and if you're like "ummm maybe that's something, or nah nah, it's probs nothing" er on the side of something and go see your GP! Mammograms are not scary," she said.

"If you do have cancer it's ideal to find it and kick it's ass before it has time to even get a look in."

Friends and fans have rallied around Gandy sharing words of encouragement.

"Gandy, I am so sorry to hear this, holy sh*t. You're positivity is going to get you through this girl," wrote ZM host Megan Papas.

"Sending big love and positivity your way," says Laura McGoldrick.

"Ok universe that's a move. I'm gutted you are going through this but already uplifted and amazed at your strength and determination. Kia kaha koe," wrote Stacey Morrison.

Gandy begins her first round of chemo next week.
