Symmetry, evolution and cancer
Symmetry is defined here as the correspondence in size, form, and arrangement of parts on opposite sides of a point, line, or plane. A ball is symmetric about a point, a pipe is symmetry about a line, and a pair of shoes is symmetric about a plane.
Water molecules in vapor have higher symmetric than water molecules in ice because the former can rotate freely and thus have point-symmetry in space, but the latter form crystal and have higher orderness. Water molecules in liquid are intermediate between those in vapor and ice in terms of both symmetry and orderness. From vapor water to crystal ice, the process is loss of symmetry and gain of orderness. This is called "automatic symmetry broken" and it happens when interactions between particles are str
engthened. The lower the temperature, the more significant the interactions.
Evolution is a process of loss of symmetry and gain of orderness. A monocell organism is ball-shaped and thus symmetric about a point, an earthworm is pipe-shaped and thus symmetric about a line, the left side and the right side of a human being are like a pair of shoes and thus symmetric about a plane. A human body has higher orderness than a monocell organism in that each cell type of a human body has specific functions but a monocell organism does "everything" by itself, just like a molecule in cryst
al has only a specific orientation but a molecule in vapor can have infinite orientations.
Cancer formation is gain of symmetry and loss of orderness. It resembles the process of turning ice to water vapor, and it's retro-evolutionary. Tumor cells are round shaped and have higher symmetry than irregularly shaped normal cells; Tumor cells are out of body control and have less orderness than well controlled normal cells. Also, tumor cells, as well as monocell organisms, can move from one place to other places, just like molecules in vapor, but normal cells stay at specific positions, just like mo
lecules in crystal.
The conditions under which a tumor is formed and ice is turned into steam are also very similar: steam is formed when interactions between water molecules are weakened, and growth of tumor cells is not limited by cell-cell contact inhibition or growth factors produced by other cell types; You can heat ice into liquid water and then into steam water, and you can "heat" normal cells into tumor cells: many carcinogens actually excite the cells and restricting food calories can inhibit cancer formation.
The inherent relationship between tumor formation and water evaporation offers us guidance on cancer research, e.g., whatever "heat" the cells may be suspected to be carcinogenic, increasing cell-cell interaction may turn tumor cells into normal cells.
