Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
The symptoms that the patient exhibits usually reflect the extent of the cancer's spread. Lung cancers that are discovered early may cause symptoms localized to the respiratory system. However, lung cancer that is advanced will cause patients to experience additional signs and symptoms secondary to the cancer spreading to other organ systems. [5]
Usually the infection of the bronchopulmonary segment remains restricted to it, although tuberculosis and bronchogenic carcinoma may spread from one segment to another. Visualising the interior of the bronchi through a bronchoscope passed through the mouth and trachea, procedure is called bronchoscopy.
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
When most tumors metastasize to the lung, they form distinct nodules, but about 7% spread through the lymph vessels of the lung. [2] They may impair breathing in several ways; the lung becomes stiffer; blood vessels traveling alongside the distended lymph vessels become compressed.
The incidence of bronchiolo-alveolar carcinoma has been reported to vary from 4–24% of all lung cancer patients. [23] An analysis of Surveillance epidemiology and End results registry ( SEER) by Read et al. revealed that although the incidence of BAC has increased over the past two decade it still constitutes less than 4% of NSCLC in every ...
Non-small-cell lung cancer (NSCLC), or non-small-cell lung carcinoma, is any type of epithelial lung cancer other than small-cell lung cancer (SCLC). NSCLC accounts for about 85% of all lung cancers. [1] [2] [3] As a class, NSCLCs are relatively insensitive to chemotherapy, compared to small-cell carcinoma.
