Famous quotes containing the word diseases:

    “The fantasies inspired by TB in the last century, by cancer now, are responses to a disease thought to be intractable and capricious—that is, a disease not understood—in an era in which medicine’s central premise is that all diseases can be cured.”
    —Susan Sontag (b. 1933)
