Antioxidants and Cancer - How Well do They Work Together?
In order to comprehend antioxidants and cancer prevention, we must first realize what antioxidants are and then how they help our bodies kill cancer. Research scientists don't fully understand the kinship between antioxidants and cancer prevention, but nonprofits, private organizations, and governments are engaged in ongoing research to look into potential dos and dont's and different medical interactions.
Antioxidants
An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules (Wikipeda). In other words it is a substance that may help protect cells from the harmful effects of unstable molecules known as free radicals. The harm caused by free radicals may cause cancer.
As the body ages, free radicals naturally occur, and the long term damage they create could possibly lead to changes in cells eventually causing grievous tumors.
Laboratory evidence from chemical, cell culture, and animal studies indicates that antioxidants may hinder or possibly prevent cancer. The benefits of antioxidants has encouraged people to turn to supplements . People hope that larger amounts of these compounds will have a more protective effect.
Antioxidants are abundantly found in nuts, grains, fruits and vegetables, as well as some meats, poultry, and fish.
Antioxidants and Cancer
The link between antioxidants and cancer prevention has been highly publicized by the media. But there have been mixed results on research into the effects of different antioxidants on cancer.
Because different foods contain different amounts of antioxidants, as well as numerous other substances that could influence cancer risk, it is exceedingly difficult for researchers to answer this question. Some concerns have been raised that antioxidants might be adverse when given with cancer treatment because they could help the cancer cells repair themselves. In fact, a recent report by the US Preventive Services Task Force concluded that there is too little evidence to either recommend for or against taking vitamins (including antioxidants) for cancer prevention.
Several doctors and colleagues examined studies into antioxidants and cancer therapy in the May 27 online edition of the Journal of the National Cancer Institute. They found that there were only three controlled studies on radiation and antioxidants.
One of these clinical studies found that the likelihood of death was raised when given antioxidant treatment. Doctors said that the antioxidants may protect cancer cells from harm just like normal cells, hence preventing cancer treatments from killing tumors.
The findings were not conclusive in 16 other randomized controlled trials that the researchers found. Overall the study apparently shows that high-dose supplements may be more harmful than helpful. The problem facing doctors today is that too little is known about how antioxidant supplements in truth act against disease.
doctors are finding it very difficult to give people advice on the subject due to the few and varied studies done on antioxidants. Until more is known and better studies are done, experts say to eat a healthy balanced diet to help lower the risk of cancer.
