Michael Strahan's daughter Isabella, 19, is praised for her 'strength' and 'courage' amid brain cancer battle - as images show her smiling happily while posing in a pink wig amid recovery from her THIRD emergency surgery

Michael Strahan's daughter Isabella has been hailed as an 'inspiration' by fans after undergoing her third emergency brain surgery in a matter of months.

The University of Southern California freshman was previously diagnosed with medulloblastoma after doctors found a tumor 'bigger than a golf ball' growing at the back of her brain, which caused her to suffer 'excruciating headaches' and vomiting.

She has since been documenting her medical journey on social media, opening up about her treatment in a series of very candid YouTube videos. 

However at the weekend it was sister Sophia who posted a cheerful slideshow of snaps to Instagram, capturing her sibling beaming with happiness while posing in a pink wig amid her ongoing treatment. 

It comes after Isabella revealed she had to undergo a third emergency craniotomy in a devastating twist that came just two days after she celebrated her chemotherapy treatment being reduced.

But this is not the first time Sophia has shown her sister online support.

In January, she posted a slideshow of the two sisters in the hospital, as well as a throwback from them as kids, and dotingly wrote: 'I'm so lucky to have the most amazing sister and best friend in the world.

'The last few months have been so much harder than we could have ever imagined, but it's made me realize just how strong you are.  

'You inspire me and I'm so proud of you. Us forever.'

The outpouring of support comes after Isabella was faced with another heartbreaking hurdle in her health journey as she candidly revealed to her followers that she has suffered another 'major setback' in her treatment.

She explained that she had to undergo another agonizing craniotomy surgery just over one month after she her last emergency procedure to drain fluid from her head.

Since first opening up about her diagnosis on the morning show, Isabella has been documenting her journey on her YouTube account, where she has racked up more than 37,200 subscribers. 

Her father added of her decision to be so open about it online, 'She's [doing it] in the hopes that other people with the same diagnosis will feel supported and know they are not alone.'
