An intervention is a treatment or action taken to prevent or treat disease, or improve health in other ways. Many studies are being done to find ways to keep cancer from starting or recurring (coming back).
Chemoprevention is being studied in patients who have a high risk of developing cancer.
Antineoplastons are chemical compounds that are found normally in urine and blood. For use in medical research, antineoplastons can be made from chemicals in a laboratory. (See Question 1.)
Antineoplaston therapy was developed by Dr. S. R. Burzynski, who proposed the use of antineoplastons as a possible cancer treatment in 1976. (See Question 2.)
No randomized, controlled trials showing the effectiveness of antineoplastons have been published in peer-reviewed scientific journals. (See Question...
Chemoprevention is the use of substances to lower the risk of cancer, or keep it from recurring. The substances may be natural or made in the laboratory. Some chemopreventive agents are tested in people who are at high risk for a certain type of cancer. The risk may be because of a precancerous condition, family history, or lifestyle factors.
Clinical trials are taking place in many parts of the country. Check NCI's PDQ Cancer Clinical Trials Registry for cancer prevention trials that are now accepting patients.
