Page "Experimental cancer treatment" Paragraph 6

Chemotherapeutic drugs have a hard time penetrating tumors to kill them at their core because these cells may lack a good blood supply.

Researchers have been using anaerobic bacteria, such as Clostridium novyi, to consume the interior of oxygen-poor tumours.

These should then die when they come in contact with the tumour's oxygenated sides, meaning they would be harmless to the rest of the body.

A major problem has been that bacteria do not consume all parts of the malignant tissue.

However, combining the therapy with chemotheraputic treatments can help to solve this problem.
