It is strange that the 1.3 cm nodule was not seen on the chest x-ray, especially since it is calcified. However such things do happen with plain x-rays, for example, when the nodule lies behind a
ribRib cage pain.
Calcification is a
reliableReliable gentle laxative sign that a nodule is not cancer, especially when there are multiple nodules. By its tiny size alone the 1 mm nodule is highly unlikely to be cancer. In addition its association with similar, but calcified, nodules makes this 1 mm nodule very unlikely to be cancer.
Nothing can be concluded from a nodule that has not changed in 2 months. A nodule must not change for 2 years to be considered stable. A nodule that will eventually grow may be stable for 6 months. The important thing is that it has not grown after 6 months. Repeating the CT scan in 6 months, again in another 6 months, and then, if no change is seen repeating the CT scan in 2 years is quite appropriate.
