Hyperbaric oxygen therapy can help heal the damage that cancer patients receive during radiation, according to an article on KMBC-TV Feb. 3, 2010.
 
The article suggests that oxygen therapy can treat cells that are damaged during radiation and are not healing correctly.
 
Mary Brandon, a hyperbaric technologist quoted in the article said that the damange of radiation on cells can take months or even years to notice, but oxygen therapy can bring back a normal division of cells.

Brandon said that oxygen therapy brings oxygen to cells that are depleted of it. “Without enough oxygen being brought to your cells, you're not going to heal,” she said.
 
KMBC-TV reported that prostate cancer patients are the most common cancer patient to use oxygen therapy at the local Kansas City medical would center, and the patients reported generally feeling improvement after about 10 treatments.
