Doctors diagnose Argentina's President with cancer

President Cristina Fernandez has thyroid cancer, but test results show that it remains limited to a lobe in the right side of her neck, and has not metastasised or spread into her lymph nodes, her spokesman said.

Alfredo Scoccimarro said the cancer was discovered during a routine exam on December 22, and that Ms Fernandez received the results from follow-up tests hours before the announcement.
