<s>[INST] hello d0ct0r, I just want t0 ask what is SMALL NODULO CALCIFIC DENSITY (R) MLF CANNOT R/O CALCIFIED GRANULOMA? I just want t0 kn0w what d0es it mean? Because when i have x-ray, they t0ld i have like that and UN-FIT TO W0RK. Hope to hear fr0m y0u. Thank y0u [/INST] A calcified nodule in the lung often suggests a remnant of an old infection that happened years ago, sometimes a subclinical infection that you were not aware of. It usually does not need further testing but in certain cases depending on the size and shape it may be prudent to repeat another x-ray after several months to ensure that it has not enlarged (and thus making it unlikely to be a tumor). This calcified nodule should not affect your ability to work, however. All the best. </s>
