肺癌

Lung cancer is the growth of abnormal cells in one or both lungs. These cells can multiply rapidly and turn into tumors that interfere with the function of the lungs and, 最终, spread to other parts of the body.

Lung cancer is the second most common kind of cancer diagnosed in the United States, and accounts for nearly a third of all cancer deaths. Most people who get lung cancer were cigarette smokers, but non-smokers get it too. Exposure to radon, asbestos, and secondhand smoke are also risk factors. In some cases, there is no known cause.

One of the challenging aspects of lung cancer is that it may be years before symptoms emerge. By the time it's diagnosed, about half the patients have cancer that's already spread outside the lungs. 

肺是如何工作的

The lung's job is to remove carbon dioxide from the blood and replace it with oxygen. It acts like a pump with every breath you take. The air you breathe comes in through your nose or mouth, and passes though your trachea, 或气管, into the lungs through two tubes called main stem bronchi. One of the tubes goes to the right lung and the other one to the left lung.

在肺部, each of the main stem bronchi divide into smaller tubes, 称为支气管, and then into even smaller tubes 称为支气管oles. The bronchioles end in tiny air sacs called alveoli where the exchange of oxygen and carbon dioxide — the gases you breathe — takes place. There are three sections of lung or lobes on the right side of the chest and two sections on the left side.

Types of 肺癌

癌症s that begin in the lungs are divided into two major types — small cell lung cancer and non-small cell cancer. The two types are distinguished by how the cancer cells look under a microscope. Each type of lung cancer grows and spreads differently and calls for different treatment.

Non-small cell lung cancer is more common and generally grows more slowly. There are four main types of this cancer. They are named for the cells in which the cancer develops: squamous cell carcinoma, 腺癌, bronchoalveolar carcinoma and large cell carcinoma.

Small cell lung cancer, sometimes called oat cell cancer, is less common. This type of lung cancer grows more quickly and is more likely to spread to other organs.

Our Approach to 肺癌

UCSF's highly experienced thoracic surgeons and thoracic oncologists provide state-of-the-art care for lung cancer. Working with specialists in radiation oncology, 肺学, pathology and radiology, we offer each patient a precise diagnosis and a tailored treatment plan.

Our thoracic surgery team helped pioneer minimally invasive 肺部手术, first with video-assisted surgery and now with robotic surgery. 对病人, this translates to shorter hospital stays, less pain and faster recoveries when compared to traditional procedures. We have established a reputation for accepting complex, challenging cases.
