Final answer:
Lung cancer, lymph gland cancer, and liver cancer are responsible for many cancer-related deaths due to the metastasis of cancer cells to these organs. Different types of cancers tend to metastasize to specific organs. Lung cancer is often caused by tobacco smoke exposure and can spread to the brain, bones, and adrenal gland.
Step-by-step explanation:
Lung cancer, lymph gland cancer, and liver cancer are responsible for many cancer-related deaths because they are common sites of metastasis, which is the spread of cancer cells from their site of origin to other organs in the body. Cancer cells can spread through the blood or lymphatic system to distant sites, and different types of cancers tend to metastasize to specific organs.
In the case of lung cancer, it is the most common cause of cancer-related death globally, particularly due to exposure to tobacco smoke. The cancer cells originating in the lungs can metastasize to the brain, bones, and adrenal gland. Similarly, lymphoma, which originates in the lymph nodes, can spread to various organs through the lymphatic system. Metastasized cancer in the liver can result from primary cancers in other organs, such as the pancreas, breast, colon, or ovaries.
