This paper will discuss what cancer is, the different types of cancer, the risk factors, treatment of cancer, and prevention of cancer. Before people can understand cancer they have to know what exactly cancer is. Cancer known medically as a malignant neoplasm is a broad group of various diseases all involving unregulated cell growth. There are around 200 different types of cancer that can affect the human body. A large percentage of people will be affected by some form of cancer or other in their lifetime. Some types are more serious than others, some cancers can be treated and others are hard to be treated so they lead to dead. Each type of cancer is unique with its own causes, symptoms, and methods of treatment. Symptoms of cancer vary based on the types of cancer. As cancer progresses to an advanced stage, common symptoms can occur for example, weight loss, fever, being excessively tired, and changes of skin. When a person has cancer they can get a lot of tumors. It is difficult to define cancer because there are so many different types of cancers. There are over 200 types of cancer. You can develop cancer in any body organs. There are over 60 different organs in the body where a cancer can develop. Cancer can affect people of all ages. Some types of cancers are bone, kidney, mouth, and throat cancer. Two of the most common types of cancer are skin and lung cancer. Skin cancer itself has three different types. Basal cell cancer is the most common but least dangerous. Squamous cancer is another type; melanoma is the last type and the most dangerous. Lung cancer is uncontrolled cell growth in the lungs. Most lung cancer is carcinomas and cause by smoking. All this are types of cancer some could be cure by surgery and others causes death and have no cure. The treatment for all this cancers is mostly radiation therapy, immunotherapy, vaccine therapy, surgery, and chemotherapy. Each year many people die out of these types of cancers around 7.5 million die each year. There are many types of cancers that have many risk factors. Doctors often cannot explain why one person develops cancer and another does not. But research shows that certain risk factors increase the chance that a person will develop cancer. Merriam Webster defines risk factor as something which increases risk or susceptibility. These are the most common risk factors for cancer growing older, tobacco, sunlight, lionizing radiation, certain chemicals and other substances, some viruses and bacteria, certain hormones, family history of cancer, alcohol, poor diet, lack of physical activity, or being overweight. Many of these risk factors can be avoided and others such as family history cannot be avoided. Most cancers occur in people over the age 65 but people of all ages, including children can get cancer too. Tobacco use is the most preventable causes of death. Each year more than 180,000 Americans die from cancer that related to tobacco use. Using tobacco products or regularly being around tobacco smoke (environmental or secondhand smoke) increases the risk of cancer. Smokers are more likely than nonsmokers to develop cancer of the lung, larynx (voice box), mouth, esophagus, bladder, kidney, throat, stomach, pancreas, cervix, or acute myeloid leukemia.

There are many different ways to treat cancer. Treatment varies based on the type of cancer and its stages. The stages of cancer refers to how much it has grown and whether the tumor has spread from its original location. Some treatments for cancer are surgery, radiation therapy, and chemotherapy.
