Biden lost his son, Beau, to brain cancer in 2015, and said on Tuesday (local time), that curing cancer was something he would like to see happen.
"I promise you, if I am elected President, you are going to see the single most important thing that changes America, we are going to cure cancer."
His comments were greeted with applause from the crowd.
In 2016, as Vice President, Biden worked on President Barack Obama's Cancer Moonshot scheme to accelerate cancer prevention.
He has also led the Biden Cancer initiative, which strives to "develop and drive implementation of solutions to accelerate progress in cancer prevention, detection, diagnosis, research, and care, and to reduce disparities in cancer outcomes".
Biden is considered the frontrunner for the Democratic nomination, with a new poll on Tuesday finding he led the field with 30 percent of Democratic voters want him as candidate, followed by Bernie Sanders on 19 percent.
