The inside of a normal cell contains nuclei which contains DNA

o This is how skin is constantly regerenated
DNA
Normal cell
Cancer cells:
The cause of all cancers is the same, damage to the DNA
o DNA is made up of nucleotides which contain genes controlling the cell cycle (when it
should copy and stop dividing)
Mutations can occur in the DNA spontaneously or through risk factors
If we get a mutation in a cell, there will be genes that can sense something is wrong and a lot
of the time it will undergo apoptosis, and another cell moves into its position
As we accrue more mutations in a cell, it will eventually become cancerous
