A 21-year-old woman from Staffordshire, England, initially thought the red rashes she found on her legs were caused by shaving.
But Rhiannon Douglas later discovered the cause was much more serious.
"At first, I just thought the rash was caused by shaving," Douglas said, reports Inside Edition. "It made sense as it was my cousin’s wedding a few days before, and because I was wearing a dress, I had shaved my legs."
She began to worry when the rash spread, so she went to the doctor.
"My legs were constantly burning, I could only wear loose-fitted clothes and I couldn't wear shoes. I had to live in flip flops," she added, reports the Mirror.
After six months of being misdiagnosed, Douglas began to feel pain in her joints and back. She was sent to the emergency room, where they carried out X-rays and detected a growth on her chest.
"On Nov. 17 it was confirmed that I had cancer, it wasn't until I woke up the next day that it sunk in but instead of getting upset I just wanted to get better," Douglas said. "When I was told I had cancer, I felt numb and never thought I would hear those words at just 20 years old."
Douglas said the diagnosis prompted her to change her lifestyle. She took the decision to become vegan and has tried out a number of natural treatments for her condition.
At a recent scan, the tumor had decreased in size and Douglas hopes the same will happen at her next check-up Jan. 16.
"I have a really positive outlook, and I’m hoping to be in remission by the summer," she added.
A rash is an unusual symptom for cancer, but it may have saved Douglas' life, as doctors told her the failure to diagnose her form of Hodgin's lymphoma at a relatively early stage could have made it untreatable.
"At the moment chemotherapy isn't essential as the tumor is shrinking by itself," she said.
