PLSE HELP ME Describe different causes of DNA damage and how they can lead to a mutation and cancer. Be sure that your response is a minimum of 2 paragraphs.

DNA damage occurs continuously as a result of various factors—intracellular metabolism, replication, and exposure to genotoxic agents, such as ionizing radiation and chemotherapy. If left unrepaired, this damage could result in changes or mutations within the cell genomic material.

All cancer is the result of gene mutations. Mutations may be caused by aging, exposure to chemicals, radiation, hormones or other factors in the body and the environment. Over time, a number of mutations may occur in a single cell, allowing it to divide and grow in a way that becomes a cancer.

Genes that repair other damaged genes (DNA repair genes)

Most DNA damage gets repaired straight away because of these proteins. But if the DNA damage occurs to a gene that makes a DNA repair protein, a cell has less ability to repair itself. So errors will build up in other genes over time and allow a cancer to form.
