Lung nodules can occur due to local causes like recurrent lung infections and sometimes due to cancer of the lungs. They can be due to tuberculosis. They can also be seen in systemic diseases like systemic lupus erythematosus, rheumatoid arthritis, sarcoidosis and scleroderma. Further evaluation will be based on whether the nodule is changing in size and systemic symptoms. A PET scan and biopsy may help in evaluation. A biopsy facilitates a histologic study of cells, which gives you a definite diagnosis. So once you have the diagnosis you will know what measures or precautious you need to follow.

If the opacity is due to tuberculosis, you could have other symptoms like evening rise of temperature and increased sweating. This also causes a loss of appetite; as such this is accompanied by weight loss. Also blood tests may show an increased ESR and lymphocytes. There could be positive mantoux test. Sometimes the opacities could be due to occupational lung disorders or Sarcoidosis. So, don't worry and discuss these options with your doctor. Take care
