Certain types of cancer can affect various parts of the body. For example, breast cancer occurs when cells in the breast tissue grow uncontrollably. It is one of the most common cancers among women, but men can also develop it. Early detection through screenings like mammograms can improve treatment outcomes. Another type is lung cancer, which primarily affects the lungs and is often linked to smoking. Symptoms may include a persistent cough, chest pain, and difficulty breathing. Treatment options for lung cancer may include surgery, chemotherapy, and radiation therapy, depending on the stage and type of cancer.
