Delaware Attorney General Beau Biden has returned to his office, two weeks after undergoing a medical procedure at a Houston cancer center.
A spokesman for the state Department of Justice says Biden was in the office on Wednesday meeting with staff.
The 44-year-old Biden was admitted last month to the University of Texas MD Anderson Cancer Center after becoming weak and disoriented during a vacation in Indiana.
His hospitalization came two weeks after emergency dispatchers received a call from Vice President Joe Biden's Delaware home, where Beau Biden has been staying, regarding a report of a possible stroke. And about a week after the younger Biden felt ill while on a family vacation in Indiana.
"You put the pieces together and say, OK, it went from finding something to needing a diagnostic procedure," said NBC News Chief Medical Correspondent Nancy Snyderman.
Snyderman said that sources familiar with Biden's condition said that he underwent a complicated biopsy.
Snyderman said that sources familiar with Biden's condition said that he underwent a complicated biopsy and that it could take days for the pathology to be studied under a microscope.
"They are looking for tissue, once you see something on a CT scan that shouldn't be there, it's called a mass." Snyderman said. "It's taking up room. You have to figure out what it is."
A mass isn't necessarily cancerous and can be anything ranging from an aneurysm to a hemorrhage to something else.

On August 21, the vice president and his wife announced their son underwent “a successful procedure.”
“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,” Biden said in a statement last month.
Snyderman says that successful could mean a range of things.
"I hear no complications," she said.
There was no immediate official word of what type of procedure was performed.
Biden suffered a mild stroke in 2010. Biden became Delaware's attorney general in 2007. He is also an army national guardsman who was deployed to Iraq in 2008.
"Typically one-quarter of those stroke patients have had symptoms before," Snyderman said on NBC Nightly News. "We do know that since his stroke, Beau Biden has had several episodes in the past."
