Brazil's former president has left a hospital after receiving his first chemotherapy treatment for throat cancer.
Doctors say former President Luiz Inacio Lula da Silva experienced no nausea following the treatment. They also say voice problems caused by the tumor have improved.
Silva will return to Sao Paulo's Sirio-Libanes Hospital for his next round of chemotherapy in three weeks. He is also expected to undergo radiation therapy early next year.
The tumor in Silva's throat was discovered over the weekend. Doctors say they are optimistic he'll make a full recovery.
His presence on Brazil's political scene is viewed as crucial to maintaining his Workers Party in power at various levels across the nation.
