When we talk about the cancer and then say that 'one is cured', we have different time durations that we take in to account to make a statement that the cancer is cured . The melanoma for example ,can come back after many years and so is breast cancer. So when we have someone with breast cancer we talk about 'disease free interval'. But sometimes we have problem. Usually the lung cancer does not come back after disease free interval of 3 years ,but I had seen one coming back after 5 years . This is rare. But then there is a increased incidence of SECOND CANCER when one has one cancer ,which complicates out thinking.
This brings me to the story for today. I had seen this male patient several years ago. He was a smoker in past and then quit. He has some COPD and also had Sleep Apnea. He had kidney mass 12 years ago and that was detected and then he had kidney taken out and that was cancerous . The oncologist and urologist did follow up and after 5 years he was told he was fine and 'cured . of renal cancer. Then 7 years ago he had a lung mass and so we did the biopsy and he had lung cancer . At that time when we saw the mass in the lungs ,we had thought of that being related to kidney cancer . But then when we took out the mass ,it was NEW LUNG CANCER and not related to his kidney cancer which was -at that time - taken out 3 years ago. The oncologist followed him and then I continued to do the new scans. After 2 years or 3 years of 'cancer free ' time , we did the scan every year. The last scan was clear and there was no cancer or recurrences of the cancer. AND when we did the new CT scan , I had a shock. On physical examination ,he had some prominence of breast bone that he had noticed few days ago and he had a mass behind the breast bone and also other mass in the lungs. So now he has a cancer - most likely and I am not sure if it is NEW or old - recurrence of the old Cancer. The work is is in progress.
