Every cell has what is called oncogenes (onco---oncology---cancer) that trigger cell replication. When the cell duplicates, the onco-switch turns off
until next time it is needed. Except once in a while, it forgets to turn off and just keeps making new cells.
What causes them to not turn off? Who knows. Smoking, Sunlight, high-voltage power lines, NutraSweet, and any number of other things. Heck, everything
these days can cause cancer.
Chemo can make some stuff worse. It is not really discriminating in what it kills. Just any rapidly growing cells. Radiation treatment at least
targets a little better. Which does beg the question, If radiation is supposed to be a strong carcinogen, then why is it used to treat cancer?
