Mexico City (CNN) -- Mexico's president will undergo surgery next week to remove a thyroid nodule, his office said Wednesday.
President Enrique Peña Nieto's operation will last about an hour and a half. Doctors at Mexico's Central Military Hospital will perform the July 31 surgery.
He will recuperate for a period of four days in his official residence, the presidency said.
Peña Nieto, 47, assumed Mexico's presidency in December.
Thyroid nodules are lumps that form within the gland, which is located at the base of the neck, according to the Mayo Clinic.
"The great majority of thyroid nodules aren't serious and don't cause symptoms," the clinic says on its website. "Thyroid cancer accounts for a small percentage of thyroid nodules."
