Thanks for your query.
A spot in the lung CT which is probably unchanged over 5 years is not cancer. Though they have not compared it yet, if it was cancer then it would have caused problems much earlier. This is just an incidental nodule.
calcification is also not something to be worried of. It is found in many healthy individuals. However, I am not sure of the cause for red and white cells in urine. Is it due to urinary infection? Or else any problem in the urinary bladder
or kidneys. We need to check the urine culture report and kidney function tests. I presume kidneys and bladder were normal on CT scan
Hope I have answered your query. i will be available to answer further followup queries, if any.
