A fitness model is sharing devastating photos of her battle with ovarian cancer.

At 23 years of age, aspiring bikini model and self-confessed “fitness enthusiast” Cheyann Shaw was diagnosed with cancer.

Just one month before her wedding, Cheyann was told she was battling ovarian cancer after an unexpected trip to the emergency room.

“I never in a million years thought this would happen to me, especially since I am only 23, but I know I will win this battle,” she wrote when she was diagnosed in August this year.

And it’s surgery time! Please send some prayers and positive vibes my way???????????????????? – – Hopefully once this is over, I’ll be one step closer to being cancer free☺️???? – – Oh and Happy Halloween!!???????????? – – #fuckcancer #ovariancancer #seattleseahawks #bestself #selflove #npc #npcbikini #ifbb #npccompetitor #bikini #bikinicompetitor #bikinifitness #bikiniathlete #fitlife #fitspo #fitlife #follow #inspiration #happiness #womensfitness #womenshealth #motivation #squat #squatspo #country #countrymusic #countrygirl #happyhalloween #surgery

Since her diagnosis, Cheyann has been sharing inspirational photographs of her chemotherapy sessions and her commitment to her passion for fitness with her 180,000 followers.

Last week, she revealed to her fans that after three rounds of chemotherapy and major surgery, she had lost a staggering 12 kilograms.

This is hard for me to post… Left- Before we knew I had cancer. I was a solid 130lbs and 15% body fat. Also had a nice little booty growing back there. – – Right- Taken yesterday. Stage 4 Low Grade Serous Ovarian Cancer. After almost 14 days in the hospital, a poop bag, and a major surgery; I stand at 105lbs. That’s way to small for me. I’m 5″5. I lost everything. Cancer has taken so much from me. The body I worked so hard for 2 years to get, the ability to have and carry my own child, my hair, and so much more, but one thing for sure is that cancer has not taken my fight and faith. – – I will never stop fighting. I will never lose my faith. I will never let cancer win. Today has been a rough day for me mentally, but that’s okay. I know tomorrow will be much better and I’m thankful to be alive and to see another day. I know GOD is up there working and I know he will give me the strength to fight, the light to see in the darkness, and will lay his healing hands on me. – – This is the toughest battle I have and will ever face, but I know I can do it. The hardest part of all this is my body change. I have a hard time looking at myself in the mirror but I’m learning to love myself again and I know this is only temporary. Once I get the clear light to workout, I’ll be in the gym banging those weights???????????????? – – #fuckcancer #ovariancancer #seattleseahawks #bestself #selflove #npc #npcbikini #ifbb #npccompetitor #bikini #bikinicompetitor #bikinifitness #bikiniathlete #fitlife #fitspo #fitlife #follow #inspiration #happiness #womensfitness #womenshealth #motivation #squat #squatspo #country #countrymusic #countrygirl #smile #cheystrong

“This is hard for me to post…[on the left is] before I knew I had cancer…[on the right] taken yesterday,” she wrote alongside the before and after pictures.

“After almost 14 days in the hospital, a poop bag, and a major surgery; I stand at 105lbs. That’s way too small for me,” she continued.

“I lost everything. Cancer has taken so much from me. The body I worked so hard for two years to get, the ability to have and carry my own child, my hair, and so much more, but one thing for sure is that cancer has not taken my fight and faith.”

I still got some muscles ???????? and 12 days till surgery???? – – Truthfully, I have been struggling with the fact that I’m not able to throw up some heavy weights and not being the strongest women in the gym ( I’m very competitive????) – – It’s hard from going from squatting close to 160lbs and being able to curl 30lbs with ease; to having to curl/do any upper body with light weight because I can’t risk my port implant moving (it’s in my chest) and struggling to squat 100lbs???? – – But at the end of the day, my strength is coming back, my arms are still decent size and my booty is growing???????????????? With surgery in 12 days, I’ll be out from working out probably around 6 weeks. So I’ll be starting at square one again but that’s okay. That just means I’ll come back better and stronger and I’ll also have a new badass scar???????? – – #fuckcancer #ovariancancer #cheystrong #seattleseahawks #bestself #selflove #npc #npcbikini #ifbb #npccompetitor #bikini #bikinicompetitor #bikinifitness #bikiniathlete #fitlife #fitspo #fitlife #follow #inspiration #happiness #womensfitness #womenshealth #motivation #squat #squatspo #countrygirl #country #countrymusic

Cheyann revealed she would “never let cancer win”.

“This is the toughest battle I have and will ever face, but I know I can do it. The hardest part of all this is my body change. I have a hard time looking at myself in the mirror but I’m learning to love myself again and I know this is only temporary.”

When she first revealed her diagnosis, she wrote, “I never in a million years thought this would happen to me.”

“I would be lying if I told you I wasn’t scared, because I’m scared shitless. I will not let cancer win,” she wrote.

“My spirit is not going to dim and I am going to live my life and fight this battle… Now it’s my time to fight, fight for my life, and let me tell you; cancer has f***ed with the wrong person.”
