U.S. Senator John McCain has been diagnosed with brain cancer, a hospital statement said Wednesday.
The tumor was found after the 80-year-old Republican senator had a surgery to remove a blood clot from above his left eye in Phoenix last Friday.
"Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot," Mayo Clinic Hospital said in a statement.
The statement also revealed McCain and his family are reviewing further treatment options that "may include a combination of chemotherapy and radiation."
According to another statement released by his office, McCain is in good spirits as he's recovering at home from Friday's surgery.
The statement said McCain "is confident that any future treatment will be effective."
Glioblastomas are tumors that arise from astrocytes, the star-shaped cells that make up the supportive tissues of the brain, according to American Brain Tumor Association.
These tumors are usually highly cancerous as the cells reproduce quickly and they are supported by a large network of blood vessels.
Lab results from McCain's surgery confirmed the presence of glioblastoma in association with the 2-inch blood clot removed during a minimally invasive craniotomy with eyebrow incision.
McCain's doctor said the procedure lasted about three to four hours, while post-surgical brain scans show the tissue that raised concerns has been completely removed.
A previous statement from the Arizona senator's office said McCain was recovering "amazingly well."
"The news of my father's illness has affected every one of us in the McCain Family," Meghan McCain tweeted on Wednesday.
"It won't surprise you to learn that in all this, the one of us who is most confident and calm is my father," she said.
McCain had three other malignant melanomas removed in 1993, 2000, and 2002, but none of them were invasive.
McCain ran for the Republican nomination in 2000 but lost to George W. Bush, while he secured a 2008 nomination but was defeated by Democratic candidate Barack Obama.
