Victoria Price, who works for Florida-based broadcaster WFLA, said she received an email which read: "Hi, just saw your news report. What concerned me is the lump on your neck.
"Please have your thyroid checked. Reminds me of my neck. Mine turned out to be cancer. Take care of yourself."
The 28-year-old explained how she almost dismissed the email - especially during her work throughout the coronavirus pandemic - putting it down to 'weird lighting'.
Now Victoria will undergo surgery on Monday (27 July) to remove the tumour as well as her thyroid and a couple of other lymph nodes.
Posting an update to Twitter, Victoria wrote about how the 'roles reversed' when the viewer emailed her and added: "I couldn't be more grateful."
She went on: "We were covering the most important health story in a century, but my own health was the farthest thing from my mind.
"Until a viewer emailed me last month. She saw a lump on my neck. Said it reminded her of her own. Hers was cancer.
"Turns out, mine is too."
A bit of ~personal news~ to share.- victoria price (@WFLAVictoria) July 23, 2020
Turns out, I have cancer. And I owe it to one of our wonderful @WFLA viewers for bringing it to my attention.

She also explained how her doctor has said it is spreading but 'not too much' and they're 'hopeful this will be her first and last procedure'.
Victoria went on: "Had I never received that email, I never would have called my doctor. The cancer would have continued to spread. It's a scary and humbling thought.
"I will forever be thankful to the woman who went out of her way to email me, a total stranger. She had zero obligation to, but she did anyway. Talk about being on your side, huh?
"The world is a tough place these days. Don't forget to take care of yourself. Take care of each other."
Replying to one of the comments on her post, she went on: "I'm still learning but doc explained that the tumor is in the middle of my thyroid, pushing the glands up and out, hence the subtle protrusion."
Thanking people for their messages, she also wrote: "The last 48 hours have been overwhelming, but the outpouring of love and support has been beyond anything in my wildest dreams. To all my new friends, thanks for joining me on my journey!"
Here's to a speedy recovery.
