So imagine yourself, your mother or father has just undergone cancer treatment and now you are afraid that the disease could be passed on to you. Now imagine yourself in the alternative knowing that the disease may depend on you and your offspring and that effective treatments exist. These are the studies that are being done in the evolutionary biology of cancer, and scientists are making great progress. Ecology and evolutionary biologists argue that natural selection plays a role in cancer genetics. The theory of evolution, Darwinism, explains the idea that species advance through natural selection and others do not. To further explain an organism's ability to survive, reproduce, and pass on its genes to offspring has to do with natural selection.3 All of this translates into the fact that you need to know your past to understand your future. Before understanding why evolutionary biology is so important for curing cancer, we need to know more about the disease in question. Cancer is the disease caused by uncontrolled division of abnormal cells in the body. Cancer is a disease that can enter the body from the environment, from taking a harmful substance, or genetically. One of the causes of cancer is environmental, meaning that factors in the environment, such as sunlight, could negatively affect the body. Substances that someone puts into their body, such as tobacco or alcohol, could also cause cancer, which means that even taking harmful substances can have negative effects on the body. Finally, cancer can be caused by genetics, which means that cancer can be passed down from generation to generation. While the premise of cancer evolutionary biology is not a new topic, there has been an increase in studies focusing on this... half of the article ......ncer can begin to tell us evolutionary models and how to apply different models of treatment previously used. In conclusion, understanding a particular genetic cancer pathway could one day, hopefully in the near future, help doctors help their patients better and more effectively. The doctor who understands the evolution of cancer has a greater advantage over others in deciding a better form of recovery for his patients. Knowing how cancer reacts can help a doctor provide better treatment to their patients, which will make them more effective in fighting and defeating cancer. Although some points relating to the complexity of cancer are currently unclear, we are on the right path. This is essentially why understanding the evolutionary biology of cancer is so important to everyday life.
