our genetics are very stable. we don't produce mutants and evolve into new species rapidly. if you see a disease like cancer incidence increasing it isn't because of genetics. people frequently say they just got unlucky when they get cancer. we give ourselves cancer. cancer grows in metabolic dysfunction. we eat ourselves into cancer. we sit ourselves into cancer. we hide inside the caves of our house into cancer. for most cancers, unfortunately we only have ourselves to blame and that is incredibly uncomfortable to think about and why we spend so much time and money finding molecular markers for malignancy that get turned on during our times of metabolic dysfunction.
