Certain cancers refer to specific types of cancer that can affect various parts of the body. For example, breast cancer primarily develops in the breast tissue, while lung cancer originates in the lungs, often due to smoking or exposure to harmful substances. Each type has its own risk factors, symptoms, and treatment options. Diagnosis of certain cancers typically involves imaging tests, biopsies, and blood tests. Early detection is crucial, as it can significantly improve treatment outcomes. Common treatments include surgery, radiation therapy, and chemotherapy, which aim to remove or destroy cancer cells and prevent their spread.
