Cancer

Cancer i/ˈkænsər/, known medically as a malignant neoplasm, is a broad group of various diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous. Benign tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body. There are over 200 different known cancers that afflict humans.

Famous quotes containing the word cancer:

    Ever since I was a kid my folks fed me bigotry for breakfast and ignorance for supper. Never, not once did they ever make me feel proud of where I was born. That’s it. That was a cancer they put in me. No knowledge of my country. No pride. Just a hymn of hate.
    Samuel Fuller (b. 1911)

    The truth is that Mozart, Pascal, Boolean algebra, Shakespeare, parliamentary government, baroque churches, Newton, the emancipation of women, Kant, Marx, and Balanchine ballets don’t redeem what this particular civilization has wrought upon the world. The white race is the cancer of human history.
    Susan Sontag (b. 1933)

    We “need” cancer because, by the very fact of its incurability, it makes all other diseases, however virulent, not cancer.
    Gilbert Adair, British author, critic. “Under the Sign of Cancer,” Myths and Memories (1986)
