The 66-year-old has a tumour¹ in his larynx（喉） , a statement from the Sirio-Libanes Hospital in Sao Paulo said.

"After multiple investigations², initial chemotherapy will start in the next few days. The patient is well," the statement read.

Lula was elected Brazil's president in 2002, the country's first leftist leader in half a century.
