Cancer

Carter, who will turn 91 in October, said he has already begun treatments for four small brain tumors.

A look at more about his situation:

WHEN WAS THE CANCER DISCOVERED?

Carter said he had a complete physical after feeling ill during a trip in May, and an MRI scan revealed a mass in his liver. A PET scan looked suspicious for cancer, and he started talking with doctors about his options.

"I'm ready for anything and looking forward to a new adventure," said Carter, appearing upbeat and making jokes as he openly talked about his cancer during a news conference.

So far, the pain has been "very slight" and Carter said he hasn't felt any weakness or debility. Still, he will cut back on his work with the Carter Center and will give the treatment regimen his "top priority." His first radiation treatment was set for Thursday afternoon.

A statement issued Tuesday by the Carter Center says the 90-year-old will address reporters Thursday morning in Atlanta.

Carter revealed on Wednesday that he had been diagnosed with cancer.

In a brief statement, he said a surgery to remove a small mass from his liver had revealed cancer that had spread to other parts of his body. He said he planned to undergo treatment at Emory Healthcare in Atlanta and promised more details soon.

Carter, 90, announced Wednesday that recent liver surgery found cancer that has spread to other parts of his body.

"I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare," Carter said in the statement released by the Carter Center in Atlanta.

The statement indicates that the 39th president's cancer is widespread but not where it originated, or even whether that is known at this point. The liver is often a place where cancer spreads and less commonly is the primary source of it.

"Recent liver surgery revealed that I have cancer that now is in other parts of my body," Carter said in the statement released by the Carter Center. "I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare."

Hogan says the cancer is B-cell non-Hodgkin's lymphoma. He says it may be Stage 4, or at least a very advanced Stage 3.

He spoke at a hastily organized news conference Monday afternoon in Annapolis, surrounded by members of his family and cabinet.

Hogan, a Republican who took office in January, says he's "shocked" by the news.

He says he's been feeling good and has had few symptoms, but has tumors, a low appetite and some pain. Chemotherapy treatment is planned.
