Expert Solution

Step 1

Cancer is an uncontrolled division of cell that has a defunct apoptosis mechanism. Usually, when cells come in close proximity to each other, they tend to get destroyed. This is a property of cell called as contact inhibition. But cancerous cells lack this property and hence they accumulate together and continue to divide in an uncontrolled manner thereby leading to tumors.
