Forum Name: Lung Cancer

Question: Vague Density in lung

 copguy30 - Mon Jan 12, 2009 8:32 pm

40 year old male, non smoker for the last 17 years. had 2 x-rays done on right shoulder. On one of two images there is a vague density measuring about 1.2 cm projecting of the lateral right lung. Have a history of lung cancer in the family, father, both uncles and grandfather, all who were heavy smokers. What are the possibilities of this being cancer or something else. Spent 20 years in the Military and during that time had a couple borderline positive TB tests. Have re eval scheduled but would like to know more about what it could be.

User avatar Hi,

It would be difficult to tell without seeing the density first hand. There are certain criteria within the density that favor benign and others that favor a malignant pathology. So I will just have to do with the information you have provided.

Certain types of lung cancer can occur in the periphery. In addition, lung cancer is a type of cancer that can carry a familial risk especially in first degree relatives and more so when it occurs at a younger age.

The fact that you are a nonsmoker reduces the risk significantly.

As regards size, 1.2 cm favors a benign rather than a malignant condition. Of course all other criteria should be available to make a better assessment.

A history of benign lung conditions / lesions especially COPD carries a risk.

I hope that helps. Please keep this thread updated.
