Final answer:
Lung metastases are likely to have come from primary cancer sites such as the breast, pancreas, colon, and ovary. Breast and ovarian cancers often metastasize to the liver as well. Lung cancer, primarily caused by tobacco smoke, has a high mortality rate, and it is commonly treated with surgery, chemotherapy, and radiation therapy.
Step-by-step explanation:
When we refer to lung metastases or 'lung mets,' we are talking about cancerous tumors that originated in other parts of the body and have spread to the lungs. Common primary sites that frequently metastasize to the lungs include the breast, pancreas, colon, ovary, and kidneys. Metastasized breast cancer, for instance, can grow in the bone, brain, and liver, as well as the lungs, while metastasized colon and ovarian cancer often grow in the liver. Lung cancer itself is a significant health concern, characterized by uncontrolled cell growth in the lung tissues. It is most commonly caused by exposure to tobacco smoke, which contains harmful substances that lead to DNA damage over time. Diagnosed often in its late stages, lung cancer treatment options may include surgery, chemotherapy, and radiation therapy, but it remains a leading cause of cancer death worldwide.
