A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be ...
The smoking of non-tobacco products is not known to be associated with lung cancer development. Marijuana smoking does not seem to independently cause lung cancer – despite the relatively high levels of tar and known carcinogens in marijuana smoke. The relationship between smoking cocaine and developing lung cancer has not been studied as of ...
Lung tumor; A chest X-ray showing a tumor in the lung (marked by arrow) Specialty: Oncology Pulmonology: Symptoms: Coughing (including coughing up blood), weight loss, shortness of breath, chest pains [1] Complications: Lung cancer: Causes: Smoking Radon gas Asbestos Air pollution Genetics
Lung squamous-cell carcinoma is the second most common histologic type of lung cancer after adenocarcinoma, reaching 22.6% of all lung cancer cases as of 2012. [11] The relative incidence of the former has been steadily decreasing in favor of the latter due to the decreasing smoking rates in the last few years. [9]
Patients with lung cancer resulting from air pollution (occupational or cigarette smoking-related) are more likely to have other lung disorders such as COPD, which limit their respiratory reserve. Patients with limited respiratory reserve are at higher risk for postoperative complications should surgical treatment be pursued; they may not be ...
Stanford University School of Medicine clinical professor and researcher Dr. Bryant Lin has been diagnosed with stage 4 lung cancer despite never smoking in his life. ... have a chest X-ray ...
However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules. [1] [4] studied the tumour-bronchus relationship and described five types: [1] In “Type 1” the bronchial lumen is patent up to the tumour. In “Type 2” the bronchus is contained in the tumor.
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 ...
