The Mechanics of Pulmonary Nodules There is very little growth or change, if there's any at all. Cancerous pulmonary nodules, however, are known to grow relatively quickly—usually doubling in size every four months but sometimes as fast as every 25 days.
Also, benign nodules grow very slowly, if at all, while cancerous nodules on average can double in size every four months or less. Nodule content, shape and color: Another way to tell a benign lung nodule from a malignant one is to test its calcium content.
The most common causes of lung nodules are inflamed tissue due to an infection or inflammation (called granulomas) or benign lung tumors (such as hamartomas). Less common, malignant lung nodules are typically caused by lung cancer or other cancers that have spread to the lungs (metastatic cancer).
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.
Studies have shown that lung cancer doubling time can vary, from 229 days to 647 days in one study, depending upon the type. 7 It's possible that some types of lung cancer progress within weeks to months, while others may take years to grow.
It takes several years for cancer to develop in the lungs. Early lung cancer does not alert obvious physical changes. Moreover, patients can live with lung cancer for many years before they show any signs or symptoms.
Patients can (and usually do) live with lung cancer for many years before it becomes apparent. Early lung cancer is largely asymptomatic and internalisation of tumours means patients are not alerted by obvious physical changes.

Yes, a lung nodule can be cancerous. But most lung nodules aren't cancerous. Lung nodules are small clumps of cells in the lungs. They're very common.
While the overall survival of the participants was 80 percent, the survival rate for the 139 participants with nonsolid cancerous lung nodules and the 155 participants with nodules that had a partly solid consistency was 100 percent. For the 991 participants with solid nodules, the survival rate was 73 percent.
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.
Results: The 3-year overall survival rate of the atients with malignant solitary pulmonary nodules was 93.6%, and the 5-year overall survival rate was 89.8%.
Most cancers grow fairly slowly; 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. Also, even if the nodule is lung cancer that is growing, there is a very good chance that surgery will cure you.
If lung nodules are large or malignant, they may cause symptoms, including: Chronic cough. Blood-tinged sputum. Shortness of breath.
Location. Location of nodules in the lung is another important predictor as nodules on the upper lobes are more likely to be malignant. Although etiology of this predilection is unclear, higher concentration of inhaled carcinogens could be a possibility.
In stage 1 lung cancer, people usually do not experience symptoms. When they do, the most common symptoms include shortness of breath, a persistent cough, and coughing up blood or blood-stained phlegm. Lung cancer is one of the most common types of cancer.
A 2018 study found that the median doubling time varies by type of NSCLC: Adenocarcinomas had a median doubling time of 261 days. Squamous cell carcinomas had a median doubling time of 70 days. Other lung cancers, which included large cell carcinomas and SCLC, also had a median doubling time of 70 days.
Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45. The average age of people when diagnosed is about 70.
Do the symptoms come on suddenly or slowly? Most lung cancers do not cause symptoms until they have spread. Symptoms usually develop slowly after the lung cancer has been growing for some time. This results in a majority of patients with lung cancer having advanced disease by the time they see a doctor.

Rapid growing, with a doubling time of less than 183 days: 15.8% Typical, with a doubling time of 183 to 365 days: 36.5% Slow growing, with a doubling time of over 365 days: 47.6%
