SEATTLE -- Vice President Joe Biden toured a Seattle research facility on Monday, saying scientists are at an "inflection point" in their efforts to eliminate cancer.
The tour is part of the White House's $1 billion proposal for a new initiative to cure cancer. Since the president's announcement during his State of the Union address in January, Biden has been visiting cancer researchers and advocates. The vice president's son, Beau, died of brain cancer last year at the age of 46.
Biden toured the Fred Hutchinson Cancer Research Center, which is spearheading immunotherapy, a treatment that attempts to use a patient's own immune system to fight cancerous cells.
Biden says he's encouraged by improved cooperation among the cancer research community.
After the tour, Biden and his entourage stopped off for pizza at Tutta Bella Neapolitan Pizzeria on Westlake Avenue.
Employees say Biden took selfies with workers, spoke on the phone with the owner's mom, and left a nice tip when he picked up his pizzas Monday evening. Workers say Biden ordered three pizzas -- a margherita, a pietro and a salame piccante.
