Because the show never gave her last name, Dr. Voigt was unsure how to contact McGuinness, and enlisted his Facebook friends to help the post go viral and somehow reach her.
To help the North Carolina resident with her search for that ideal beach house, she made an appearance on HGTV's "Beachfront Bargain Hunt".
Nicole McGuiness was featured on HGTV's 'Beachfront Bargain Hunt.' Dr. Eric Voigt was watching from home and noticed the 31-year-old had a lump in her neck. He turned to Facebook hoping to track her down. Taking Voigt's advice seriously, she went to the hospital and surely enough, was diagnosed with Thyroid cancer shortly after. "It stood out - and I went from being relaxed to [thinking], gosh, she may have a medical problem".
Hopefully, McGuinness will be successful in her fight against cancer once again - and her recovery will be all thanks to Dr. Voigt, whose quick thinking may just have saved a life.
"As a head and neck surgeon, I'm trained to notice these things", he told ABC News.
Others saw his post and got him directly in touch with the woman, Nicole McGuinness of North Carolina, according to reports from Newsweek and ABC News.
"I am watching a TV show and notice this woman has a left thyroid mass", he wrote.
Even as he didn't know the woman's last name, the doctor refused to ignore the symptom and chose to track her down.
"She will be seeing a surgeon and getting appropriate treatment and I hope she will be cured!" "I can't express how grateful and thankful I am".
"The woman was notified by people who saw my post, fantastic power of Facebook!"
In a heartwarming encounter on Good Morning America on June 5, Voigt and McGuinness met for the first time during the emotional segment.
Voigt said helping McGuinness was a humbling experience for him.
