Staging systems are specific for each type of cancer (e.g., breast cancer and lung cancer), but some cancers do not have a staging system.

From there it spreads in fairly predictable pattern. Typically, if lung cancer spreads, it first goes to nearby lymph nodes, followed by lymph nodes further away located between the lungs in a space called the mediastinum. In the mediastinum, the lung cancer tends at first to stay on the side where the original tumor started. Once it crosses ...
This means that if breast cancer metastasizes to the lungs, the secondary tumor is made up of abnormal breast cells, not of abnormal lung cells. The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M".
The American Cancer Society estimates that in 2023, there will be about 238,000 cases of lung cancer, and about 127,000 people will die from lung cancer. Smoking is the number one risk factor for ...
Signs of death or strong indications that a human is no longer alive are: Respiratory arrest (no breathing); Cardiac arrest (no pulse); Brain death (no neuronal activity); The heart and lungs are vital organs for human life due to their ability to properly oxygenate human blood (lungs) and distribute this blood to all vital organs (heart).
Worldwide, lung cancer is the most diagnosed type of cancer, and the leading cause of cancer death. [ 95 ] [ 96 ] In 2020, 2.2 million new cases were diagnosed, and 1.8 million people died from lung cancer, representing 18% of all cancer deaths. [ 3 ]
