Egoístas, inmortales y viajeras

Egoists, immortals and travelers explores the past, the current reality and the future of a disease that, strictly speaking, is not a single entity but more than two hundred different ones, as many as cell types build the different organs and tissues of our body. We will first discuss the origin of cancer, a question that until recently had no concrete answer and of which today we can say that it is a disease of the genes on the planet of genes. This disease causes cell transformation, by virtue of which a normal cell becomes a selfish entity that grows without restraint, immortal that ignores the death signals received by damaged cells and is a traveler, capable of leaving its tissue of origin and colonizing. other territories to form metastases. Our unwanted and undesirable preferential place among the victims of malignant tumors derives not only from the errors intrinsic to the copying of our genetic material, but from our absurd perseverance in creating forms of biological interference that have multiplied our natural risk of suffering from cancer. Voluntary exposure to carcinogens, inadequate nutrition or increasing pollution of the environment interfere with a molecular harmony that took more than three and a half billion years to settle and build beings as complex as humans.
