PHOENIX -- A Tucson, Ariz. woman reportedly lost 47 pounds in one day after doctors successfully removed a massive tumor.
According to WBTV.com, patient Marcey DiCaro underwent a 10-hour surgery at the University of Arizona Medical Center to remove the tumor.
The tumor was in DiCaro's vena cava - which is the body's largest vein and carries blood from the rest of the body back to the heart. Doctors say if they hadn't removed the tumor, it would have become even bigger, started to target other organs, and ultimately been fatal.
During the procedure, DiCaro had a heart attack but doctors were able to save her.
"If the tumor had been let go, it would have killed me," DiCaro said. "The whole team approach was wonderful. I'm happy to be going on walks and getting back in the pool and getting out and enjoying life."
DiCaro first noticed pain in 2011 and a 2012 scan revealed the tumor. However, she was unable to get health insurance and delayed the surgery until May 2014.
