Beau Biden released from hospital

Delaware Attorney General Beau Biden was released from a top cancer hospital in Texas Thursday.

Biden, who is the son of Vice President Joe Biden, underwent a biopsy procedure Tuesday night at the University of Texas MD Anderson Cancer Center.

"You can read from that that it's likely there was a tumor or some kind of tissue left behind from this mass that was biopsied," Dr. Nancy Snyderman, NBC News chief medical editor, said Wednesday on Nightly News. "Sometimes, if there's a complicated biopsy, it means you just don't have enough tissue to really make a definitive diagnosis."

Biden had a restful Tuesday night in the hospital and was expected to return home to Wilmington, Del., Thursday. Doctors might not be able to declare a diagnosis for days or weeks, Snyderman said.

He suffered a stroke three years ago when he was 41.

The vice president canceled three appearances scheduled for Thursday in Rhode Island and Maine to stay in Houston with his son.

“Yesterday our son Beau underwent a successful procedure. He is in great shape and is going to be discharged tomorrow and heading home to Delaware. He will follow up with his local physicians in the coming weeks,” the vice president and his wife, Dr. Jill Biden, said in a statement released Wednesday.

The eldest Biden was admitted last week to Northwestern Memorial Hospital in Chicago after feeling weak and disoriented following a drive to Indiana for a family vacation. He spent the weekend home in Delaware after consulting with his doctor in Philadelphia.

Biden tweeted a message and photograph Thursday.
