Cancer is a result of a default cellular ‘safe mode,’ physicist proposes

… “To use a computer analogy, cancer is like Windows defaulting to “safe mode” after suffering an insult of some sort,” Davies writes.

The result of this malfunction is the start of a cascade of events that we identify as cancer – a runaway proliferation of cells that form a tumour, which eventually becomes mobile itself, spreading to other parts of the body and invading and colonizing.

Orthodox explanations suppose that cancer results from an accumulation of random genetic mutations, with the cancer starting from scratch each time it manifests; however, Davies and Lineweaver believe it is caused by a set of genes that have been passed on from our very early ancestors and are “switched on” in the very early stages of an organism’s life as cells differentiate into specialist forms.

The pair suggests that the genes that are involved in the early development of the embryo – and that are silenced, or switched off, thereafter – become inappropriately reactivated in the adult as a result of some sort of trigger or damage, such as chemicals, radiation or inflammation.

“Very roughly, the earlier the embryonic stage, the more basic and ancient will be the genes guiding development, and the more carefully conserved and widely distributed they will be among species,” Davies writes.

Several research teams around the world are currently providing experimental evidence that shows the similarities between the expression of genes in a tumour and an embryo, adding weight to Davies and Lineweaver’s theory. …
