Smoking dramatically will increase the chance of growing lung most cancers, the kind most certainly to unfold to the central nervous system. These with a household historical past or private historical past of cancers or CNS problems ought to obtain common checkups. There isn't any efficient screening program for CNS cancers, so observing doable signs is vital.
