Small cell lung cancer. How long was it there when you can see it on x-ray?

In brief: Weeks to months
There is no hard and fast rule.
In studies that tried to detect lung cancer early using a chest x-ray, almost half of the cancers appeared within a year of a normal x-ray. Taking into account the rate of growth of a cancer cell, and the minimum size needed for detection on x-ray, a good estimate for small cell is a few weeks to a few months.

In brief: Since it is the
Fastest growing lung cancer and the one that screeningchest x-rays rarely caught, the usual reason for this question is that you had a symptom or an x-ray and it was not seen, is there malpractice? Most sclc is central and endobrohchial befre it is seen as nodal enlargement in the hilum or the medistinum. It is always caused by smoking.
Treatment can be quite successful.

In brief: Unknown
The best screening test for high risk patients 50y/o or older is a low dose cat scan thorax.
Traditional x-rays are likely to miss early lung cancers. Specially if centrally located.

In brief: Appearance versus
Initiation time of small cell lung cancer.
Many will assert that they can tell by "doubling time" the non-small cell types. I find this speculative and not proven. Small cell seems to appear much more rapidly and be large and even metastatic at first appearance. A 1 cm lesion has 7 logs of cells. Small cell have less cell-loss than other tumors lacking apoptosis, it takes months to get this big.
