Table 2. Difference in nodule size with elapsed time.
| Time of first and second CT | Interval between first and second CT (days) | Size of nodule on first CT (mm) | Size of the same nodule on second CT (mm) | Difference in diameter (mm) | Difference in size |

Due to scheduled operations and controlled CTs verifying the results of the oncological treatment, we were able to count the number of recurrences and measure their size and observe the growth dynamics of the same lesion in a given time period. For measurement of nodules in terms of change in size in connection with elapsed time, we choose two different time periods. Nodules in both lungs were compared. All visible tumors were measured and given in millimeters. Percentage of nodule development and mean values are shown. The 100-day normalized growth ratio in both periods is also represented. According to our results, the speed of nodule enlargement is significantly slower with elapsed time (P=0.023).
