Brazil President Rousseff diagnosed with pneumonia

BRASILIA,  (Reuters) – Brazilian President Dilma  Rousseff has been hospitalized with pneumonia and will remain a  second night for more tests, a spokesman said today.
Rousseff was taken to Sao Paulo’s Sirio Libanes hospital on  Saturday after several days of strong flu symptoms,  presidential palace spokesman Rodrigo Baena said.
Brazil’s first female president and a cancer survivor,  Rousseff canceled her participation at the World Economic Forum  in Rio de Janeiro on Friday because she felt ill. She had been  expected to remain in Brasilia during the weekend.
No further details were released.
Rousseff revealed in April 2009 that she was undergoing  treatment to remove an axillar lymphoma, a cancer in the  lymphatic system, that was in early stage at the time. She  submitted to curative chemotherapy treatment for four months.
