A Left-Truncated Life Tables session allows survival to be figured from a certain age rather than from the DX Date as in a Survival session. Left-Truncated Life Tables sessions make it possible to see if people who survive cancer live longer than those who did not have cancer because they take better care of themselves and whether cancer survivors have the same causes of death as people who did not have cancer.
It is recommended that you work through a Left-Truncated Life Tables session in the following order.
