There are many causes of lung nodules but the two most common reasons for the development of nodules in the lungs are infection and inflamed tissue – usually as a manifestation of another medical condition like chronic rheumatoid arthritis or tuberculosis. Now, if an individual is experiencing lung pain, it does not mean that the person has lung cancer but it is nonetheless important that the patient seek medical advice immediately to rule out cancer.

1. Are Lung Nodules Cancerous?
Lung nodules are usually detected through an x-ray or CT scan procedure. These are generally
made up of tissues in the lungs that form into a mass, no more than five mm. to twenty-five
mm.
Imaging through x-ray or CT scan that reveals a white spot on the lungs that is of a size no
bigger than an inch will most likely be a benign mass rather than a malignant tumor.
Non-Cancerous Nodules
Generally, lung nodules detected in individuals, with no accompanying symptoms, are benign.
This means that the nodules are non-cancerous and in fact, they are relatively common in
adults especially in people who smoke.
If a lung nodule has been detected, the chances that this is malignant are minimal.
However, doctors will most likely ask their patients to be on the lookout for signs or
symptoms that may reveal that the nodule could be developing in size; which in turn could
translate to the mass having developed into a tumor.
Usually, if a lung nodule has been detected, doctors will prescribe medications to get rid of
the problem. After several weeks, the patient may be required to take another imaging test to
see if the nodule was removed through medication or if it changed in size.
What Causes Lung Nodules?
There are various causes of lung nodules; one of which is infection. Bacterial infection in the
lungs such as tuberculosis causes the formation of lung nodules but these will eventually go
away with proper medication.
Sometimes, medical conditions may also cause the formation of lung nodules. For instance, if
a person is suffering from chronic rheumatoid arthritis, nodules in the lungs may develop, in
the form of inflamed tissues.
Pain in the Lungs
Oftentimes, a person experiencing lung pain will go to the doctor to find out the reason behind
it and only after imaging tests have been done that a nodule or a mass is detected.
Since lung nodules do not generally manifest any symptom, the discovery of these nodules
may be via a routine or annual check-up – not specifically through a procedure intended to
confirm the presence of nodules.
However, if a person has experienced pain in the lung area it does not immediately translate to
lung cancer. Sometimes, upper back pain is mistaken for pain in the lungs.

2. But if the pain is persistent and you feel other symptoms such as shortness of breath or
difficulty in breathing, persistent cough, coughing-up blood or sudden weight loss without
dieting; these could be signs of a more serious condition.
An x-ray followed by a CT scan or MRI may be required to see the condition of the lungs.
