(R) Arizona Sen. John McCain Diagnosed with Brain Cancer

Last Friday, Sen. John McCain underwent surgery to remove a blood clot above his left eye. After the surgery, the retired 80-year-old Republican senator took rest days in his Arizona home. But it was not until Wednesday that his office officially announced that John was diagnosed with brain cancer, which had led to the clot.

Glioblastoma Tumor Surgically Removed

In the statement, his office revealed that John was optimistic and also very thankful to the Mayo Clinic staff for their remarkable care and support. The surgical team removed the most aggressive tumor, glioblastoma, which had caused the blood clot. The senator, who is in Arizona with his family, is in good spirits and very optimistic that future treatment will be effective.

According to doctors at Mayo clinic, the senator is responding quite well to treatment, and his underlying health is exceptionally excellent. The doctors also continue to review possible treatment options for the senator. He and his family are considering a combination of radiation and chemotherapy.

His daughter Meghan McCain took to Twitter to write a heartfelt message for her dad. She captioned that the entire family is shocked by the news. Referring to her father’s battle with skin cancer in 2000’s, Meghan said the senator remains the strongest and calmest of them all. “He is the toughest person I know. The cruelest enemy could not break him,” read her quote.

McCain’s Public Service

After the news of McCain’s surgery had hit the news last week, the Senate decided to delay the GOP health bill vote until his recovery.

McCain joined public service in 1982 when he was elected to the House of Representatives. Four years later, he was elected senator and selected the chairman of the Senate Commerce Committee as well as Senate Armed Services Committee. In 2008, he joined the presidential race with Sarah Palin as his running mate. However, the two were defeated by Barack Obama and his running mate Joe Biden.

On Wednesday evening, politicians, Republicans and Democrats alike flooded twitter with heartfelt messages wishing the senator a quick recovery.
