What to know if you have lung nodules (2024)

FAQs

What to know if you have lung nodules? ›

Most lung nodules do not cause any symptoms or interfere with your breathing. However, if you develop new symptoms related to your breathing, or a cough, or a change in your symptoms that you are worried about, you should discuss with either your hospital doctor or GP, who can review and identify any potential causes.

If you have a lung nodule, it is important to see a specialist, like a pulmonologist, because if your nodule falls into the 5% that are cancer, early detection greatly improves your treatment outcomes.

Half of all patients treated for a cancerous pulmonary nodule live at least five years past the diagnosis. But if the nodule is one centimeter across or smaller, survival after five years rises to 80 percent.

Also rarely, you could experience signs that might indicate early stage lung cancer (cancer that hasn't spread outside the lung). Contact your healthcare provider if you have lung nodules and start to experience: Chest pain. Chronic cough or coughing up blood.

Are lung nodules cancerous? 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.

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.

Treatment for lung nodules may range from a “watchful waiting” approach for benign nodules, to surgery, chemotherapy and radiation therapy for malignant nodules.

A noncancerous lung nodule shouldn't affect your quality of life and most don't require treatment. If you have an infection in your lungs, this will be treated with antibiotics. If a lung nodule is causing problems or is found to be cancerous, you may require surgery to remove it.

Results: 1746 (51.5%) participants had one nodule, 800 (23.6%) had two nodules, 354 (10.4%) had three nodules, 191 (5.6%) had four nodules, and 301 (8.9%) had>4 nodules. Lung cancer in a baseline nodule was diagnosed in 134 participants (139 cancers; 4.0%).

What are the symptoms of a cancerous lung nodule? ›

Lung nodules are small growths in your lungs less than 30 mm in diameter. The majority of these nodules aren't cancerous, but the risk becomes higher with increased size. A doctor may want to perform regular follow-ups for nodules larger than 6 mm or for smaller nodules if you have a high risk of lung cancer.

Well recognized features such as spiculation, pleural retraction, pleural thickening, the bronchus or vessel sign (airway or vessel leading directly to lesion), or part solid characteristics are all associated with a significantly increased risk of malignancy in pulmonary nodules, especially when evaluated at thin ...

Stage I is divided into 2 substages based on the size of the tumor: Stage IA tumors are 3 centimeters (cm) or less in size. Stage IA tumors may be further divided into IA1, IA2, or IA3 based on the size of the tumor. Stage IB tumors are more than 3 cm but 4 cm or less in size.

The doubling time for most malignant nodules is between 30 and 400 days. The absence of growth of solid nodule over at least a 2-year period is generally considered to be a reliable indicator of benignity.

Most lung nodules seen on CT scans are not cancer. They are more often the result of old infections, scar tissue, or other causes. But tests are often needed to be sure a nodule is not cancer. Most often, the next step is to get a repeat CT scan to see if the nodule is growing over time.

If the CT scan shows small nodules (less than a centimeter wide, or about the size of a green pea), they have a low probability of being cancerous. Larger nodules are more worrisome. Rounded nodules are less likely to be cancerous than spiculated (having jagged edges) ones.

Positron emission tomography (PET) scan – A PET scan can help your doctor determine if a lung nodule is non-cancerous or cancerous, because it allows them to get a more detailed look. Biopsy – During a biopsy, your doctor removes a small amount of tissue from the nodule to examine closely under a microscope.
