They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A larger lung nodule, such as one that's 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule.

Small intrapulmonary lymph nodes are very difficult to diagnose by methods other than surgical resection. When a small intrapulmonary nodule is detected in a patient with primary lung cancer, the presence of an intrapulmonary lymph node must be considered.

However, as a result of the development of radiographic screening tools, such as high-resolution (HR) CT, the frequency of detection of early-stage lung cancer has been increasing. Most of them have a characteristic appearance on HRCT known as GGO and small sized (diameter ≤2 cm) peripheral malignancies (Figure 1).

There are a number of different kinds of benign lung tumors, the most common being hamartomas. They account for about 55% of all benign lung tumors, and 8% of all lung tumors. Characteristics of lung hamartomas: About 80% are found in the peripheral, or outer, portion of the lung's connective tissue.

An 6mm ring is as about the width of three nickles stacked together. A standard U.S uses nickle measures 1/16 of an inch, which is almost 2mm wide. Three nickles, or 6mm, would measure 6/16 inch.

A typical pair of human lungs contain about 300 million alveoli, producing 70 m2 (750 sq ft) of surface area. Each alveolus is wrapped in a fine mesh of capillaries covering about 70% of its area. The diameter of an alveolus is between 200 and 500 μm.

Stage II non-small cell lung cancer is divided into stages IIA and IIB. In stage IIB, the tumor is 5 centimeters or smaller and cancer has spread to the lymph nodes on the same side of the chest as the primary tumor. The lymph nodes with cancer are in the lung or near the bronchus.

The nodule may go away on its own or stay the same size. Patients treated this way should be checked by their doctor every 6 months to monitor the growth of the nodule. As long as the nodule does not grow, there's usually no need to worry.

Lung Masses and Growths. Lung cancer is a mass or growth in the lung made up of cancer cells, but not all masses in the lung are caused by cancer.

A congenital pulmonary airway malformation (CPAM) is a mass of abnormal fetal lung tissue that forms during pregnancy. This mass, or lesion, is usually located in one lung and it does not function as normal lung tissue. Lesions vary in size and appearance and can change significantly during the pregnancy.

What is a lung nodule? Commonly called a “spot on the lung,” a nodule is a round area that is more solid than normal lung tissue. It shows up as a white spot on a LDCT scan. Lung nodules are usually caused by scar tissue, a healed infection that never made you sick, or some irritant found in the air you breathe.

The term thyroid nodule refers to an abnormal growth of thyroid cells that forms a lump within the thyroid gland. Although the vast majority of thyroid nodules are benign (noncancerous), a small proportion of thyroid nodules do contain thyroid cancer.

2mm = just over 1/16 inch. 3mm = almost 1/8 inch. 4mm = 5/32 inch (= a bit over 1/8 inch) ... 6mm = almost 1/4 inch.

Primary lung sarcoma is a very rare malignant tumor, accounting for less than 0.5% of all lung tumors. The variety of soft tissue sarcomas reflects the range of the mesenchymal tissues present in the lung. The three most common sarcomas include leiomyosarcoma, malignant fibrous histiocytoma and synovial sarcoma.

While the chance is small that you have cancer — 95 percent of lung nodules are not cancerous — it's normal to feel worried if you don't know. Be reassured: Having nodules on the lung is common, but getting lung cancer is not. At least 50 percent of adults have nodules in their lungs by the time they are 50 years old.

It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.

6mm = almost 1/4 inch. ... 8mm = 5/16 inch. 9mm = almost 3/8 inch. 10mm = just over 3/8 inch.
