If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

Yes and no. When Cancer starts to spread, it begins as clusters of cells that form tiny colonies in other body parts. These will grow in size over a few months to become visible on X-rays and various diagnostic imaging tests such as CT scan and or PET scan. Blood tests do not show cancer cells , so we rely on the above imaging tests and repeat them periodically(every 2-3 months) to monitor for the tumor growt.
