Radiation therapy-oxygen effect, Physics

Oxygen effect:

The oxygen effect may play a role in the recurrence of cancer .The cell near the center of a large tumor have a poor blood supply and thus  a poor oxygen supply .When the tumor is irradiated the (healthy ) cancer cell with a good blood supply are killed and many of the more  poorly oxygenated radio resistant  tumor cell remain a live . These cells many later divided and permit the tumor to re-grow
