Tumor Cells Quotes

… human population growth within the ecosystem was closely analogous to the growth of malignant tumor cells within an organism: that man was acting like a cancer on the biosphere. The multiplication of human numbers certainly seems wild and uncontrolled... Four million a month - the equivalent of the population of Chicago... We seem to be doing all right at the moment; but if you could ask cancer cells, I suspect they would think they were doing fine. But when the organism dies, so do they; and for our own, selfish, practical, utilitarian reasons, I think we should be careful about how we influence the rest of the ecosystem.

Aside from bringing back extinct species, reanimation could help living ones by restoring lost genetic diversity. The Tasmanian devil (aka Sarcophilus harrisii) is so inbred at this point that most species members can exchange tumor cells without rejection.

Cancer's life is a recapitulation of the body's life, its existence a pathological mirror of our own. Susan Sontag warned against overburdening an illness with metaphors. But this is not a metaphor. Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.

I believe that we are going to have a much deeper appreciation of what kinds of abnormalities in cancer cells and in the surrounding cells that feed and respond to cancers are vulnerabilities that will allow us to make better predictions of which kinds of drugs will work to treat these cancers.

A fundamental premise in cancer therapy is trying to identify how the metabolism of cancer cells differs from normal tissue. When differences are identified, it often paves the way for treatments that will disrupt the cancer's metabolism while sparing normal tissue.

The most dangerous cancer cells are actually the ones that are more like stem cells, which have this ability to produce themselves over and over again. More and more cancer biologists say stem-cell-like cells in cancers are the most dangerous.
