Margaret Thatcher, Britain's first and only female Prime Minister, had surgery this week.
Thatcher, who is 87, had surgery to remove a tumor from her bladder, and is reportedly recovering well. She has been ill in recent months, missing a high profile luncheon held by the Queen celebrating the Prime Ministers who have served during her reign. Thatcher's office in the House of Lords was closed in 2011 and, according to media reports, suffers from dementia.
Thatcher began her career as a chemist, only later attending law school and entering the world of politics. She served as Prime Minister for an unprecedented term spanning 1979 to 1990.
