Part 5: Testing for lung cancer
Surgery types
There is more than one type of surgery for lung nodules. See Figure 4. Often,
a small part of a lobe will be removed to test for cancer. This surgery is called
a wedge resection. If cancer is found, then a larger part of the lung may be
removed. A segmentectomy removes a large part of a lobe, whereas a lobectomy
removes the whole lobe.
A normal lung on the right side of the body has three lobes. The left-sided lung
has two lobes. Removing one lobe typically reduces lung capacity by 20% to
25%. For example, if before surgery your lungs were able to take in 6 liters of air,
then after removing one lobe your lungs would take in 4.5 to 4.8 liters. Thus, your
surgeon will likely test your lung capacity to make sure that it is safe to remove
part of your lung.
