Nearly a year and a half after his cancer diagnosis, Maryland Gov. Larry Hogan (R) on Monday received his final chemotherapy treatment.

Hogan posted a picture on social media of himself with a wide grin, reclining in a hospital chair with his fists raised and an intravenous line running to his chest.

“I can’t tell you how it feels to be getting my very last chemo treatment today,” the post reads. “I plan to make the most of every single day I am given, and I won’t stop fighting until a cure is discovered for this terrible disease.”

Hogan announced in May 2015 that doctors had discovered dozens of tumors throughout his body and diagnosed him with Stage 3 non-Hodgkins lymphoma. The governor started on an aggressive chemotherapy regimen that required Lt. Gov. Boyd Rutherford last year to fill in for him occasionally at meetings and public events.

After doctors said in November that tests showed that he was in remission following 18 weeks of aggressive treatment, Hogan began receiving monthly treatments, he said, to prevent the disease from returning.

On Monday, Hogan thanked his doctors and nurses at the University of Maryland Medical Center and said in a Facebook post that he was “humbled by the thousands of prayers and well wishes” and was “deeply grateful to be 100 percent ­cancer-free.”
