Study finds cancer-prevention benefits in antioxidant drugs

Antioxidant drugs may aid cancer treatment

People who receive antioxidant drugs may be better prepared to battle cancer, according to a recent study on the topic.

While Dr. Michael Lisanti's team already knew that oxidative stress and cancer were linked, they were determined to delve deeper into the question. They found that the presence of high levels of a protein called Caveolin-1 in patients with an aggressive form of breast cancer drastically increased survival rates by reducing oxidative stress and helping cells resist the mutated cancer genes.

"Cancer cells are parasites, and the way they do their business is that they use oxidative stress as a weapon to extract nutrients from adjacent normal cells," Dr. Lisanti told MyHealthNewsDaily.

However, the news source also reported that other studies had failed to establish a link between antioxidants and reduced cancer severity, including a large-scale Chinese trial in 2009.

Experts say there are other upsides to antioxidants as well, as a lack of them has been anecdotally linked to all manner of conditions that can reduce life expectancy and drive up mortality rates.
