Question: What is melanoma and is it life-threatening? Answer: Melanoma is a type of skin cancer and is considered to be the most dangerous form of the disease. Although less commonly diagnosed than other types of skin cancer, melanoma accounts for over 75% of skin cancer deaths. Melanoma develops in cells called melanocytes that are found in the lower part of the epidermis, the outer layer of your skin. Melanocytes are cells that are responsible for creating skin pigmentation, or melanin. Melanin is what gives our skin its natural hue.
In the 18th century only the American revolution produced a sustainable democracy. During the 19th century monarchists fought a prolonged rearguard action against democratic forces. In the first half of the 20th century nascent democracies collapsed in Germany, Spain and Italy. By 1941 there were only 11 democracies left, and Franklin Roosevelt worried that it might not be possible to shield âthe great flame of democracy from the blackout of barbarismâ.
The same ideas, but with more radical assertions of social as well as political equality, nourished the French Revolution of 1789. France, however, did not achieve real democracy until the Third Republic (1870â1940). During the 19th century democratic forms of government also developed in Britain â where the Reform Acts of 1832, 1867, and 1884 greatly expanded parliamentary suffrage â and in the self-governing British colonies of Australia, New Zealand, and Canada, as well as in Switzerland, Scandinavia, and the Low Countries.
