Maryland Senate President Thomas V. Mike Miller said Thursday he will undergo radiation therapy after the General Assembly session ends Monday, as he continues treatment for prostate cancer.
He has received five rounds of chemotherapy, but amid signs the regimen’s effectiveness is waning, doctors are switching his treatment to radiation, said Jake Weissman, Miller’s chief of staff.
Chemotherapy involves using drugs to stop the spread of cancer throughout the body. Radiation is used to target and shrink tumors; Miller said he will begin receiving doses to his pelvis and spine starting April 10.
Miller, the longest-serving state Senate leader in the country, announced in January he had been diagnosed weeks earlier with “advanced” prostate cancer. The Democrat who represents parts of Calvert, Charles and Prince George’s counties has been Senate president since 1987.
He has received chemotherapy throughout the General Assembly’s 90-day session, missing only two days in Annapolis. He is being treated at Johns Hopkins Hospital in Baltimore.
Meanwhile, Democratic House Speaker Michael Busch is being treated for pneumonia and is likely to miss the last two weeks of the legislative session.
Miller told senators Thursday he would provide them with updates on his health every few months, and that he planned to update the Democratic majority in person at a gathering in the fall.
“In November, we’ll have a caucus and let you know how everything is,” he said. “It’s about the Senate; it’s not about me.”
Miller added that he is in good spirits.
“Mentally, I’m fine,” he said.
