Cancer is a disease characterized by uncontrolled growth and spread of abnormal cells in the body. There are many different types of cancer, which can be classified based on the type of cell or tissue where the cancer originates. Some common types of cancer include:
- Carcinomas: Cancers that start in the skin or the tissue that lines organs, such as the lungs, liver, and stomach.
- Sarcomas: Cancers that start in bones, cartilage, and connective tissue.
- Leukemias: Cancers that start in blood-forming tissue, such as the bone marrow.
- Lymphomas: Cancers that start in the immune system, such as in the lymph nodes.
- CNS Cancers: Cancers that start in the brain and spinal cord.
The type, location, and stage of cancer will determine the course of treatment, which may include surgery, radiation therapy, chemotherapy, and other forms of therapy.
