But as is true of many construction projects, permits must be obtained. The body must accept that what is being built is approved of as “self.” Anything seen as alien to the point of being pathogenic will be destroyed, and the site will not be rebuilt. There is a dangerous corollary. Once permission is given, once the new cells being nourished are deemed “self,” the construction can go on with zeal. The trouble is, the new cells aren’t always self. Sometimes they are cancer.
