(CBS News) -- Sen. John McCain (R-Arizona) will continue radiation and chemotherapy as part of his brain cancer treatment and remain in the Senate, according to a statement released by his office to CBS News.

"Senator McCain received an MRI at the National Institutes of Health (NIH) in Bethesda, Maryland yesterday," the statement reads. "Following the advice of his doctors, Senator McCain will continue to receive targeted radiation and chemotherapy treatments at NIH while maintaining a regular work schedule in the United States Senate."

The senator was diagnosed with a cancerous brain tumor in July after a blood clot procedure. He underwent his first round of chemotherapy and radiation in mid-August.

On Monday, McCain told news outlets his brain prognosis was "pretty good," and said while he has "faced other challenges," he's "very confident about getting through this as well."
