President Fernando Lugo's opponents are calling for him to step aside after recent health challenges.
Last week he jetted to Brasil for emergency treatment after being hospitalized from complications from his lymphatic cancer.
His doctor said Lugo had a blood clot, a common side effect of chemotherapy.
But he was treated successfully and did not require surgery.
Opponents say Lugo still faces chemotherapy treatments and more risk of complications. They say he should take a leave of office to focus on getting better first.
It was at least the third health scare this year for Lugo, 59. He had prostate surgery in January and was diagnosed with cancer in August.
Under the constitution, the president can stay abroad for only five days before he must ask Congress for permission to remain longer.
