Many people have lung nodules. These abnormal growths are rarely cancerous. Respiratory illnesses and infections can cause nodules to form in the lungs. Most lung nodules are not a sign of lung cancer and don’t require treatment. On X-rays or scans, these growths may look like a shadow or spot on the lung.

What causes lung nodules?
When an infection or illness inflames lung tissue, a small clump of cells (granuloma) can form. Over time, a granuloma can calcify or harden in the lung, causing a noncancerous lung nodule.
A neoplasm is an abnormal growth of cells in the lung. Neurofibromas are a type of noncancerous neoplasm. Types of malignant (cancerous) neoplasms include lung cancer and carcinoid tumors.
Other causes of noncancerous lung nodules include:
•Air irritants or pollutants.
•Autoimmune diseases, such as rheumatoid arthritis and sarcoidosis.
How are lung nodules diagnosed?
Most people find out they have a lung nodule after getting an imaging test in preparation for a procedure or another purpose. The findings are often a surprise. If an imaging test shows a lung nodule, your healthcare provider may recommend active surveillance. In six to 12 months, you get another CT scan. Nodules that stay the same size during a two-year surveillance period are not likely to be cancer. You may be able to stop getting CT scans. Your provider may order further tests if the nodule is large (more than half an inch, or about 12 millimeters) or it grows. These tests include: Bronchoscopy: While you’re sedated, your provider threads a thin tube (bronchoscope) down your throat into the lung. A tiny surgical instrument on the end of the scope snips and retrieves a tissue sample from the nodule. A lab analyzes this biopsy sample for abnormal cells. CT scan-guided biopsy: For nodules on the outer part of the lung, your provider uses CT images to guide a thin needle through the skin and into the lung. This needle biopsy takes tissue samples from the nodule to examine for abnormal cells. Positron emission tomography (PET) scan: A PET scan uses a safe, injectable radioactive chemical and an imaging device to detect diseased cells in organs.
What are the complications of lung nodules?
Rarely, a noncancerous lung nodule may press against or block the airway. You may need surgery to clear the airway so you can breathe clearly again.
How are lung nodules managed or treated?
Small, noncancerous lung nodules don’t usually require treatment. You may need treatments, such as antibiotics or antifungal medications, if you have an infection. If the nodule grows, causes problems or is cancerous, you may need surgery. Surgical procedures to remove noncancerous and cancerous pulmonary nodules include: Video-assisted thoracic surgery (VATS): During VATS, your provider inserts a thoracoscope (scope with a camera) and tiny surgical instruments through several small chest incisions. Your provider refers to images from the camera to remove the nodule. Thoracotomy: Your provider removes the lung nodule through a larger incision between your ribs, below your shoulder blade. For several days after the surgery, a tube drains excess fluid from your chest. Care at Cleveland Clinic Lung Nodule Treatment Find a Doctor and Specialists Make an Appointment
How can I prevent lung nodules?
Quitting smoking is the best thing you can do to protect your lungs. But there isn’t anything you can do to prevent lung nodules.
What is the prognosis (outlook) for people who have lung nodules?
Most lung nodules aren’t cancerous and don’t require treatment. A noncancerous lung nodule shouldn’t affect your quality of life.
When should I call the doctor?
You should call your healthcare provider if you experience: Chest pain. Chronic cough or coughing up blood. Unexplained weight loss.
What questions should I ask my doctor?
You may want to ask your healthcare provider: What is the best plan of action for me? Do I need a biopsy? Should I look out for signs of complications? A note from Cleveland Clinic Lung nodules are fairly common and usually aren’t cause for concern. Still, it can be alarming to learn that you have a spot on your lung. Fortunately, the majority of lung nodules aren’t a sign of lung cancer. A noncancerous condition causes the abnormal growth. Most benign lung nodules don’t need treatment. If a nodule is cancerous, your healthcare provider can discuss next steps. Medically Reviewed Last reviewed by a Cleveland Clinic medical professional on 05/28/2021.
