Unlocking the Cancer Code: Unraveling Hereditary Mutations

Abstract

A Cancer Pedigree Part II Worldwide, hereditary cancer accounts for 10 percent of global cancer cases. It is, therefore, crucial to understand hereditary and non-hereditary cancer mutations. Cancer is a recurring disease on my mother’s side since it is in every generation. Cancer genes that pass from one generation to the other are called germline mutations. In this context, cancer on my mother’s side is caused by the inherited faulty cancer genes which are passed from the parents to the child (Hogan Smith, 2017). Studies show that if a parent has a cancer fault gene, the child has a 0.5 probability of inheriting the cancer gene. This implies that there is a high chance of some children developing cancer while others do not. The inherited cancer genes also increase the chances of a person developing cancer when younger. Families that have a cancer history, mostly have relatives who do not have the cancer faulty gene. In such families, you find that cancer mostly affects older people. Our bodies are made up of cells that have a nucleus that contains chromosomes made of genes. Genes control how our bodies function (Mahon, 2016). When genes become faulty and start to form mutations, there is a high likelihood of developing cancer cells, Health experts say that cancer develops when our cells fail to work properly. The cells associated with acquired or inherited cancer are called somatic mutations. These mutations mostly occur in the genomes of dividing cells. Additionally, the cell mutations also occur during DNA replication and when the cells are exposed to exogenous and endogenous mutagens. These mutations that are passed from the parent to the child are called autosomal recessive inheritance. This is a syndrome where a child inherits a copy of a changed gene from the parents. Studies show that...
