Question
Chapter 20, Problem 4P
Summary Introduction
To determine:
Whether the views regarding germ-line mutations and environmental factors as the cause of cancer conflicting or can be reconciled.
Introduction:
Any abnormal change in the gene sequence is known as mutation. Mutations can lead to various ailments, including cancer. Mutations can lead to uncontrollable growth of the cells leading to the development of cancer.

Students have asked these similar questions
Some germ-line mutations predispose individuals tocancer, yet often environmental factors (chemicals,exposure to radiation) are considered major risks fordeveloping cancer. Do these views of the cause ofcancer conflict, or can they be reconciled?
What is cancer? What defects are commonly found in cancer cells? Do all cancer cells have mutations in the same genes? Explain.
Unlike many other diseases, the vast majority of cancers in humans are not transmissible - meaning a person can’t ‘catch cancer’ from someone else. How does a person get cancer, then? Starting with a normal (non-cancerous) cell, describe a possible sequence of events that could eventually result in metastasized cancer, including the genes, structures or processes involved.
