Benign Lung Tumors
What are benign lung tumors?
A lung tumor is the result of abnormal rates of cell division or cell death in lung tissue, or in the airways that lead to the lungs.
Carcinoid s are an uncommon group of s, developing from neuroendocrine cells. The neuroendocrine cells are in some respect like nerve cells and in other ways like cells of endocrine (hormone-producing) glands.
Freezing treatment may help destroy lung tumors
'Cryoablation' might offer therapeutic option for cancer patients whose disease has spread.
s are divided into two broad categories: small cell carcinoma and non-small-cell carcinoma.
Lung tumors almost always start in the spongy, pinkish-gray walls of the bronchi-the tubular, branching airways of the lungs.
s have been observed in rats exposed to antimony trioxide by inhalation.   
EPA has not classified antimony for carcinogenicity.
Physical Properties ...
Most lung tumors are not treated with thoracic surgery since patients seek medical care later in the disease process. Chemotherapy increases the rate of survival in patients with limited (not advanced) disease.
Most s are malignant. This means that they invade and destroy the healthy tissues around them.
The tumors can also spread to nearby lymph nodes or through the bloodstream to other organs. This process is called metastasis.
Unlike most lung tumors, carcinoid tumors have not been associated with smoking, air pollution, or exposure to chemicals. There are no known ways to prevent this type of cancer.

Once a cancerous lung tumor grows, it may or may not shed cancer cells. These cells can be carried away in blood or float away in the fluid, called lymph, that surrounds lung tissue.

Lung cancer is unlikely to produce symptoms until the disease is advanced. When symptoms develop, they may result from the lung tumor itself, from its effects on tissues outside the lung, or from the spread of malignant cells to other organs.

The primary clinical significance of HPD is the almost invariable radiologic misdiagnosis of a primary or metastatic lung tumor, which usually leads to thoracotomy with open lung biopsy or wedge resection of the lung to obtain the correct diagnosis.
This does not mean that it cannot spread to other portions of the body as well, but doctors have seen most instances where s have spread to brain or bone mass.
Atelectasis may occur because part of the airway above the atelectasis becomes obstructed (for example, from a lung tumor), or from simple disuse (often after surgery, patients tend not to breathe as deeply, and part of the airways collapses).
