Cancer is one of the most dangerous and common diseases in the world, causing millions of deaths each year. This article will help you have a better understanding of the causes, symptoms, and treatment methods of cancer. 1. What is cancer? Cancer is a group of diseases characterized by the abnormal growth of cells that divide uncontrollably and have the potential to invade and destroy normal body tissues. More than a hundred distinct forms of cancer. Cancer is frequently called for the organ where it originates. For example, lung cancer originates from cells in the lungs, and colon cancer arises from cells in the colon. Additionally, cancer can also be named based on the type of cells that form it, such as carcinoma (cancer of epithelial cells) or sarcoma (cancer of connective tissues). Some cancers also develop from blood cells, known as hematologic malignancies. 2. Causes of Cancer 2.1 DNA Mutations Cancer is caused by changes (DNA mutations) in cells. The DNA inside a cell is packaged into a large number of individual genes. Each gene contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide. Errors in these instructions can cause the cell to stop functioning normally, potentially leading to cancer. These mutations are the most prevalent mutations observed in cancer. However, many other gene mutations can contribute to the disease. 2.2 Unhealthy Lifestyle Daily lifestyle habits are also considered one of the factors that increase the risk of cancer. Smoking, drinking more than one alcoholic beverage a day (for women of all ages and men over 65) or two drinks a day (for men 65 and younger), excessive sun exposure or frequent sunburns, obesity, and unsafe sexual practices can all contribute to cancer. 2.3 Heredity If cancer runs […]
