does it mean i have cancer because i have a nodule in my lower right lung?

Answer 1

No, it's not necessarily cancer. A biopyy should be performed to see if it is malignant or not.

Answer 2

Most Solitary Pulmonary Nodules are benign, but they may represent an early stage of lung cancer.
Pathophysiology: An SPN is defined as a single, discrete pulmonary opacity that is less than 3 cm in diameter, surrounded by normal lung tissue, and not associated with adenopathy (any disease of a gland, especially lymphatic gland) or atelectasis (a collapsed or airless state of lung tissue brought about by occlusion of, or external pressure on, a bronchus or bronchiole, with subsequent absorption of distal air).
Generally, a pulmonary nodule must reach 1 cm in diameter before it can be identified on a chest radiograph. For a malignant nodule to reach this size, approximately 30 doublings would have occurred. The average doubling time for a tumor is 120 days (range, 7-590 d). A lesion at this growth rate may be present for 10 years before discovery.
Risk of malignancy increases with age.
* For individuals younger than 39 years, the risk is 3%.
* The risk increases to 15% for individuals aged 40-49 years, to 43% for persons aged 50-59 years, and to more than 50% for persons older than 60 years.(eMedicine)
Most nodules in patients over 35 years old should be considered potentially malignant until proven otherwise. If the lesion is suspected to be benign, serial chest x-rays or CT scans may be taken on a regular basis for observation of the lesion. If the affected person is at high risk for lung cancer or if the CT scan appearance of the lesion suggests it is malignant, surgical removal of the lesion (excisional biopsy) is recommended.

Answer 3

I have three tiny nodules in my upper right lung however I do not have cancer. A Broncoscophy with biopsy can tell you for sure!

Answer 4

It could mean that.

Or it could be a granuloma (a benign lump) from an irritant..ie a tubercule (type of granuloma) from exposure to TB

Or it could be bird fungus from pidgeons...cryptococcosis or histoplasmosis

I have a granuloma that has never been biopsied (no insurance at the time of discovery) and it has never gotten any larger over the years (xrays)...so they call it benign..
