A first time mum was left stunned after what she thought to be pregnancy symptoms turned out to be a tumour the size of a grapefruit between her lungs.
Kirsty Axworthy was around 12 weeks pregnant when she started to experience symptoms such as high blood pressure, night sweats, exhaustion and migraines.
However, when the symptoms failed to subside weeks after she gave birth to her daughter Elle alarm bells started to ring.

After things worsened the 26-year-old was diagnosed with stage one Non-Hodgkin's primary mediastinal large b-cell Lymphoma in July - a cancer that develops when white blood cells that help fight infection become abnormal.
Kirsty has since had chemotherapy to shrink the 13cm "ticking-time-bomb" tumour located in her mediastinum, the area that separates the lungs.
The devoted mum credits her daughter, now 11 months old, who she described as a "wee miracle" for giving her "something to live for" while undergoing her gruelling treatment.
Thankfully, Kirsty received the good news in January that she's now in remission.
The mum is now passionate about raising awareness of Non-Hodgkin's Lymphoma and has urged anyone who may have any potential symptoms to visit their GP.
She encouraged people to press for answers until they're received.
Kirsty, from Perthshire in Scotland, said: "The doctor said that if I didn't get it out and it carried on growing I probably would have ended up suffocating because my lungs would have just collapsed because of the area it's in and it's a fast-growing, aggressive form of Lymphoma.
"He said that if I didn't start chemotherapy in the next couple of weeks, I don't even know how long I would have to be honest. I'm really lucky that it was caught in time. It was like a ticking-time-bomb. It's quite scary actually.
"The tumour was around 13cm when I was diagnosed and they said it was about the size of a grapefruit. That's obviously why I was getting shortness of breath, because it was pushing against my lungs."
The mum-of-one said that another symptom she had was unexplained weight loss despite her eating well and having cravings throughout her pregnancy.
She said: "I was really really exhausted as well but because Elle was premature and I was up a few times during the night feeding and things, I just put things down to being a new mum really.
About four weeks after Elle was born, Kirsty started getting "really visible veins" on her chest and over the tops of her arms. She put it down to post-pregnancy, but then developed other symptoms.
The concerned mum kept becoming breathless, and also had a red and puffy face. She saw the GP who referred her to hospital, where she received her life-changing diagnosis the following day.
She started chemotherapy a fortnight later, which involved six rounds, but contracted pneumonia when she was halfway through.
Kirsty said: "I literally went from being pregnant, to giving birth and then seven weeks later being diagnosed with cancer and having to deal with chemotherapy. It was just so difficult.
"When they told me I had a cancerous tumour in my chest, the first couple of days I was just in complete shock and didn't really cry or anything and then the week after that it sort of hit me when I came home and started chemotherapy.
"It's hard enough going through chemotherapy at any stage but when you've just given birth and that's supposed to be such a special time. It just felt so unfair."
As of January, the avid runner has now been in remission and no longer has active signs of disease on her tumour.
She said: "I have my husband and he's amazing, as well as my family and friends, but I think that Elle definitely just gave me that extra push.
"Especially times where I was in hospital for longer periods, like when I had pneumonia. I was so weak and mentally and physically drained. She was something to live for really, that's the bottom line. I knew I had to get home and get better for her."
The mum-of-one has dedicated an Instagram account to raising awareness of Non-Hodgkin's Lymphoma which has amassed more than a thousands followers, and hopes to do so via other means once she's fully recovered.
Kirsty said: "If there's anything that you're worried about at all, go to the doctors. I know how busy day-to-day life can be, especially for mums. You think you don't have time to go to the doctors if there's something wrong.
"But with these things, and especially with my example because it was so fast-growing and aggressive, you really have to catch these things quickly because if they spread it just makes it so much more difficult to treat.
"If you think there's something not right, doctors can put a lot of things down to anxiety and just give you tablets to mask things, but you really have to get to the root of the problem, that's key.
"Just press on GPs for answers, 100%."
