Is There a Time Line – Months Etc – For Non Small Cell Lung Cancer to Mets to Brain Bone Liver?

It is almost impossible to know when the tumor first started growing, so by the time cancer is diagnosed the patient may have had cancer for a few years. And cancer is different for every one!! I really can't stress this enough. I know others who have lung cancer, we get the same chemo, have the same radiation and see the same doctors, but each of reacts differently to treatment. My cancer went from the left lung to the right lung and then to the spine. In another patient it went from the lungs to the brain, and for yet another patient I know the cancer went from the lung to the bone in his leg. the tumor growth is different for each of us and the formation of new tumors is different for each of us. All this makes it very difficult to predict the course of the disease. the person above me who said "ask your doctor" is obviously very immature and has no business trying to answer question in a serious forum.

Is there a time line – months etc – for non small cell lung cancer to mets to brain bone liver?
