I doubt any oncologists would dare render an opinion as they might lose their malpractice insurance...As explained to me by my wife, who got a fairly rare form of cancer (Rhabdomyosarcoma) as a teen, some people just have a genetic pre-disposition to forming cancerous cells. Cancer, in lay terms, is essentially the unregulated growth of cells normally controlled by genetic signals. Cancer research revolves around the quest to regulate cell formation and growth via signalling pathways. That's why fruit flies are used to study cancer--their cells can mimic some of the pathway signalling found in humans. Environment (pollution) or lifestyle (smoking) can trigger these abnormalities. In Ms. Reeves case, stress could have been a triggering event and the "genetic misfiring" showed up in her lung tissue. In other people, their signalling pathways are rock solid--my neighbor who just passed on; born in 1922, smoked every day of his adult life...never got cancer. B/t/w, nice avatar--120 shakes a minute.
