Ajay Rochester shares an intimate video from her recent breast check.

Former Biggest Loser host Ajay Rochester has recorded herself in a state of vulnerability to send a brave message to Australian women: get your breasts checked.

The 47-year-old filmed herself en route to the scan and admitted she was nervous about the scan as she felt she had “lumpy breasts”.

“So, I’m about to get my breasts checked,” she said. “I have always been a bit of a no news is good news person but I know actually that’s not true.”

The messages came via a string of video posts on Instagram where Rochester explained why she was undertaking the scans.

Rochester said it was her background as a cancer-fighting advocate and figure within the charitable community that has inspired her to publicise her own journey.

The first Instagram post also revealed her personal connections to battlers who had lost the fight.

"And having worked and been friends with Belinda Emmett (who after ten LONG Years lost her fight against breast cancer)."

Have to say ..... With a lumpy breast..... And having worked and been friends with Belinda Emmett (who after ten LONG Years lost her fight against breast cancer) ....and as a single mom in a country with the SHITTIEST health system (especially for a country that calls itself the greatest country on earth ) getting a breast scan is necessary .......

The next video was filmed at the Sound Breast Institute in Santa Monica and captured the former host receiving the initial stages of the check.

A technician explained that Rochester was receiving a check via an ultrasound because she didn't want to be exposed to the radiation in a mammogram.

The technician said although her procedure was an alternative to getting a mammogram, it should be used in conjunction - not as a substitute.

This is it! A painless 30 minute ultrasound.... That can detect #breastcancer MUCH EARLIER in dense breasts than a mammogram can and is PAINLESS! I've waited wayyyyy too long to get my breasts checked especially with a weird lump in my right breast..#soundbreastinstitute @lisawattswisdom here we go...... Fingers crossed........ The beauty of this machine is that it detects cancer early in dense breasts A video posted by Ajay Rochester (@ajayrochester) on Jun 7, 2016 at 10:49pm PDT

The final video of the series captures Rochester sharing the good news of her positive results.

"I cannot tell you the feeling of relief you get when you know that everything is clear," she said. "It's thirty minutes of your time, it's a tiny amount of money and you have peace of mind."

The series has attracted several comments from her fans who have supported her decision to go public with the news.
