Why is it that cancer does not form every time there is a mistake during the cell cycle?

Cells will actually kill themselves through a process called apoptosis, or it will be attacked and killed so it doesn’t spread. For example, when you are exposed to the sun for a long period of time, the solar radiation can mess with your skin cells. That’s why you get sunburned: the cells dry up and fall off. Otherwise, you could get skin cancer

All cancers develop because something has gone wrong with one or more of the genes in a cell. A change in a gene is called a 'fault' or 'mutation'. These faults can make a cell stop working properly. It may then become cancerous and divide and grow uncontrollably.

Explanation:

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
