The single "Killer Queen" from Sheer Heart Attack reached number two on the British charts, and became their first US hit, reaching number 12 on the Billboard Hot 100. It combines camp, vaudeville, and British music hall with May's guitar virtuosity. The album's second single, "Now I'm Here", a more traditional hard rock composition, was a number eleven hit in Britain, while the high speed rocker "Stone Cold Crazy" featuring May's uptempo riffs is a precursor to speed metal. In recent years, the album has received acclaim from music publications: In 2006, Classic Rock ranked it number 28 in "The 100 Greatest British Rock Albums Ever", and in 2007, Mojo ranked it No.88 in "The 100 Records That Changed the World". It is also the second of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.

Cancer is now common in developing countries. According to a study by the International Agency for Research on Cancer, "In the developing world, cancers of the liver, stomach and esophagus were more common, often linked to consumption of carcinogenic preserved foods, such as smoked or salted food, and parasitic infections that attack organs." Lung cancer rates are rising rapidly in poorer nations because of increased use of tobacco. Developed countries "tended to have cancers linked to affluence or a 'Western lifestyle' — cancers of the colon, rectum, breast and prostate — that can be caused by obesity, lack of exercise, diet and age."
