How Cancer Affects the Cells, the Body, and their Offspring
Have you ever wondered how cancer forms? Well, cancer starts when a cell 's DNA becomes altered. When the DNA is altered, the cells reproduce without restriction and do not die like a normal cell. These extra cells form a mass of tissue that is a tumor. Cancer forms in the genes of our cells, and is able to be carried in the offspring of the person with cancer. The cells are the basic units of life. Cells contain DNA that make up genes. Genes are instructions for the cells to make certain proteins. These proteins are then used as a blueprint for the function and structure of the organism. When the DNA is mutated, it alters the normal growth of the cells. This results in the cells not dying as they normally would, and a tumor may form; these tumors are commonly called "cancer" (www.cancer.gov). A tumor can be benign, which means it is not cancerous, or it can be malignant, which is cancerous. The tumor is comprised of abnormal cells. These abnormal cells then take over the organ that they begin in and are also named after it. For example, if a single cell becomes abnormal in the liver, and then forms a cancerous tumor, it would be malignant, and would be called liver cancer. Although, not all cancers form tumors. Also, abnormal cells can spread to other areas of the body besides where they originally started (www.cancer.gov). The gene…
