Subtitle Forum: What are the 4 Main Types of Cancer?
Cancer is an umbrella term for a group of diseases that are characterized by the uncontrolled growth and spread of abnormal cells. Cancer is one of the leading causes of death worldwide, and it is estimated that 1 in 6 deaths globally are due to cancer. While there are many different types of cancer, the four main types are carcinoma, sarcoma, lymphoma, and leukemia.
Carcinoma is a type of cancer that begins in the skin or in tissues that line or cover internal organs. Carcinomas are the most common type of cancer, and they can affect almost any part of the body. Common examples of carcinomas include breast, lung, and colorectal cancers.
Sarcoma is a type of cancer that begins in the bones, muscles, tendons, cartilage, and other connective tissues. Sarcomas are less common than carcinomas, and they can be found in almost any part of the body, including the arms, legs, chest, abdomen, and pelvis.
Lymphoma is a type of cancer that begins in the cells of the immune system, called lymphocytes. Lymphomas can occur in any part of the body, but they are most commonly found in the lymph nodes and other lymphoid tissues, such as the spleen and thymus.
Leukemia is a type of cancer that begins in the blood and bone marrow. The bone marrow is the soft, spongy tissue inside the bones that is responsible for making blood cells. Leukemia is most common in children and young adults, and it is typically seen in the white blood cells, which help the body fight infections.
