A mum posted photos of her mysterious bruises in a heartbreaking final Facebook post before her death at 22.
The emotional post saw Sarah Armstrong, 22, warn others of the dangers of acute myeloid leukaemia.
The mum was diagnosed with the cancer after a visiting the doctors with "flu-like" symptoms and undergoing a simple blood test, reports Liverpool Echo.
She died on Sunday despite starting chemotheraphy.
Sarah had posted on Facebook: "So a few weeks ago I noticed bruising on my arms, legs, stomach, thighs and back but [I] thought nothing of it [and] I was probably just knocking myself on things and carried on with my normal day-to-day life.
"Then I started experiencing flu-like symptoms such as dizzyness, cold, hot flushes and tiredness.
"But [I] put this down to down to catching things at work because you catch all sorts working in a hospital.
"But it was one morning, I woke up with my arm aching and I checked my arm to discover I had a massive black/purple bruise that I couldn't possibly of knocked.
"Then that day I started experiencing my gums randomly bleeding for hours without it stopping.
"So on Tuesday [January] 21 I went to the doctors and was sent for blood tests.
"The next day a new bruise developed on my arm, but this time with a lump, so I went straight to A&E, to which I was told it's not an emergency, go and get your blood done that your GP has sent for.
"The next day I got my bloods done and carried on with work and on the Friday, I was in work and had a phone call off a doctor to say my blood count is low, I have anemia and I need to go straight to hospital.
"To which I have now been told at the age of 22, I have acute myeloid leukemia, which is an aggressive blood cancer.
"[I] have been in hospital since they told me on the Friday and expected to be here for a few weeks on chemotherapy.
"I still have a long way to go with more treatments and tests, however I am positive and I know I will beat this!
"Please anybody who has unexplained bruises, feels generally unwell [and] reads this goes [to] the doctors because knowing the symptoms can save your life."
The healthcare assistant, from Fazakerley, Liverpool, was described as a "strong and positive" woman.
Her childhood friend Danielle Johnson, 22, said: She was just full of life. I just can't believe it, we were sitting there laughing the night before she died.
"They started the chemotherapy and she was doing amazing. She was always positive."
"She was full of life. She was really positive, she did everything for everyone.
"She was always laughing and she always made everyone laugh. She was an amazing mum, she just always put everyone first."
