Lung cancer is one of the most common types of thoracic oncology worldwide. In Israel, around 1,500 new cases are diagnosed annually, mainly in smokers over the age of 40. In about 90% of cases, smoking is the primary cause.
Primary lung cancer originates in the lung tissue, while secondary lung cancer refers to metastases from other parts of the body that reach the lungs.
In roughly 30% of cases, lung cancer is detected at an early stage, making lung lobe resection a viable treatment option (typically stages I and II, though sometimes possible in stage III). At later stages, where metastases are present, treatments such as chemotherapy or radiation therapy are usually preferred.
About 85% of lung cancer cases are non-small cell lung cancer (NSCLC), which is typically operable. Small cell lung cancer (SCLC), in contrast, is rarely suitable for surgery.
The lungs are composed of five lobes: three in the right lung and two in the left. The type and scope of lung resection depend on the tumor’s size, location, and type.
There are three main types of surgery:
- Wedge resection in Israel – removal of a small section of the lung, typically for patients with low pulmonary function
- Lobectomy in Israel – removal of a full lobe
- Pneumonectomy in Israel – removal of an entire lung
Each year, about 700 lung resections are performed in Israel, primarily due to cancer, but sometimes due to other conditions such as trauma or severe infections.
