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:
“I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?”
—Sarah N. Cleghorn (1976–1959)
“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)
