An enlarged Virchow's node as seen on CT. Malignancies of the internal organs can reach an advanced stage before giving symptoms. Stomach cancer, for example, can remain asymptomatic while metastasizing. One of the first visible spots where these tumors metastasize is one of the left supraclavicular lymph node.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process.
Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume; High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung
The signs and symptoms of this specific type of lung cancer are similar to other forms of lung cancer, and patients most commonly complain of persistent cough and shortness of breath. Adenocarcinoma is more common in patients with a history of cigarette smoking, and is the most common form of lung cancer in younger women and Asian populations.
Another study concluded that cigarette smoking is the predominant cause of large cell lung cancer. It estimated that the odds ratio associated with smoking two or more packs/day for current smokers is 37.0 in men and 72.9 in women. [9] Notable people with the condition include American comedian Andy Kaufman, who died from the disease in 1984.
A mediastinal tumor is a tumor in the mediastinum, the cavity that separates the lungs from the rest of the chest. It contains the heart , esophagus , trachea , thymus , and aorta . The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20% ...
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 ...
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]
