In general, a lung nodule can be removed very safely and using a minimally invasive surgical approach. Your surgeon may want to perform a bronchoscopy to take a closer look at your nodules and take a biopsy. A biopsy involves removing a piece of your lung to look at it under a microscope.
Nodules between 6 mm and 10 mm need to be carefully assessed. Nodules greater than 10 mm in diameter should be biopsied or removed due to the 80 percent probability that they are malignant. Nodules greater than 3 cm are referred to as lung masses.
In the vast majority of cases, lung nodules turn out to be small benign scars, indicating the site of a previous small area of infection. These nodules may be permanent or may even spontaneously disappear by the time of the next scan. Most are of absolutely no consequence.
Benign nodules are almost always healed over “wounds” on the lung left from tuberculosis or a fungal infection, although there are other, less common causes. Cancerous nodules can be the first stage of a primary lung cancer, brought on by smoking or any other common cause of lung cancer.
Benign lung nodules can be caused by inflammation from a number of conditions. They include: Bacterial infections, such as tuberculosis and pneumonia. Fungal infections, such as histoplasmosis, coccidioidomycosis or aspergillosis.

Most nodules are noncancerous (benign), and a benign nodule will not turn into cancer. But some nodules turn out to be cancerous (malignant). Small nodules, especially those that are smaller than 1 centimeter, are rarely cancerous.
How common are benign lung nodules? Pulmonary nodules are fairly common. They are seen in about one of every 500 chest X-rays and in about one out of every 100 chest CT scans. At least 60% of pulmonary nodules seen on chest X-rays turn out to be benign, and 99% of those on chest CT are benign.
Benign lung nodules and tumors usually cause no symptoms. This is why they are almost always found accidentally on a chest X-ray or CT scan.
A non-cancerous (benign) tumour of the lung is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are usually not life-threatening.
Most lung nodules are benign, or non-cancerous. In fact, only 3 or 4 out of 100 lung nodules end up being cancerous, or less than five percent. But, lung nodules should always be further evaluated for cancer, even if they're small.
Providers may be more worried about larger lung nodules and those that grow over time. If your nodule is large or is growing, you might need more tests to see if it's cancer. This might include imaging tests, such as CT and positron emission tomography (PET) scans. Another test might be a procedure called a biopsy.
A thoracotomy usually takes three to six hours. During this procedure, your surgeon: Makes an incision in your chest and spreads your ribs apart. Performs planned lung resection.
According to the Fleischner society, nodules <6 mm in diameter (or <100 mm3 in volume) are considered small enough to discharge the patient,[1] while the respective cutoff is somewhat lower (<5 mm or <80 mm3) in the earlier ACCP and BTS guidelines,[2,3] based on the results of the study of Horeweg et al., who found ...
The location of the lung nodule may guide the care team in evaluating possible risk, and studies indicate that nodules in the upper lobe may be more indicative of cancer. However, not all nodules in the upper region of the lung are cancerous, and not all nodules located elsewhere are benign.
Most lung nodules don't cause any symptoms and are often found on a chest X-ray or CT scan performed for another reason. If symptoms are present, they may include: Coughing. Coughing up blood.
Generally, benign tumors grow slowly, but they can sometimes stop growing or may even shrink. These tumors usually don't require removal or treatment and aren't life-threatening. While lung tumors may grow and press upon neighboring tissue, they won't invade, eradicate, or replace them.
Types of benign lung nodules
Most of them are found in the outer edges of the lung tissue. They're made up of excessive amounts of normal tissue like cartilage, fat, and muscle. They're usually less than 4 centimeters in diameter, and they usually look like they're coin shaped on an x-ray.
Generally speaking, malignant nodules grow fast, usually doubling in size in just six months. Nodules that grow slower are less likely to be cancerous. Inflammation in the lung resulting from an infection or disease. An infectious fungus, a lung abscess and even tuberculosis can cause nodules in the lungs.
Lung nodules are relatively common.
Lung nodules are spots ranging between . 2 inches and 1.2 inches and are relatively common—in many cases a lung nodule turns out to be benign, or noncancerous. Lung nodules are found in up to half of adults who get a chest X-ray or CT scan, according to the American Thoracic Society.
Most cancers grow fairly slowly, and it takes several months for them to get bigger. So even if the nodule is lung cancer, it will likely still be small in a few months.
Treatment for lung nodules may range from a “watchful waiting” approach for benign nodules, to surgery, chemotherapy and radiation therapy for malignant nodules. If the nodule is benign, your physician will monitor the nodule periodically with CT scans, to determine if any changes in size or shape have occurred.
Malignant pulmonary nodules indicate cancer and will require medical attention and surgery. There are many ways to reduce the likelihood of malignant lung nodules and improve overall lung health: Stop Smoking/Don't start. Engage in exercises that promote lung health like running, yoga, hiking, etc.
These are often referred to as nodules on x-ray. Surgery with this limited extent of disease can result in 80-90% cure rates. As the tumor spreads into the lymph nodes of the lung, then the chest, and then to other parts of the body, the staging number increases. The higher the stage, the less the chance for cure.
