How can free radicals cause cancer

A few studies have found benefits associated with antioxidant use, but the results have been modest. A study , for instance, found that long-term use of beta-carotene could modestly reduce the risk of age-related problems with thinking. This raises questions about what free radicals are, and why they form. It is possible that free radicals are an early sign of cells already fighting disease, or that free radical formation is inevitable with age.

Without more data, it is impossible to understand the problem of free radicals fully. People interested in fighting free radical-related aging should avoid common sources of free radicals, such as pollution and fried food. They should also eat a healthful, balanced diet without worrying about supplementing with antioxidants. The healing powers of pomegranates have been championed for centuries. High in antioxidants and vitamin C, pomegranates are said to fight viruses….

If you're wondering what foods you should be including in your diet, look no further. We cover an A to Z of popular healthy food items. Polyphenols are compounds found in plants, including flavonoids and phenolic acid, that greatly benefit the human body and help fight disease. A study identifies a link between social isolation and inflammation, suggesting that inflammation may help explain why isolation increases disease….

How do free radicals affect the body? Medically reviewed by Debra Rose Wilson, Ph. What are free radicals? How do free radicals damage the body? Causes Antioxidants and free radicals What we do not know Free radicals are unstable atoms that can damage cells, causing illness and aging.

Share on Pinterest Free radicals are thought to be responsible for age-related changes in appearance, such as wrinkles and gray hair. Share on Pinterest Free radicals are unstable atoms. To become more stable, they take electrons from other atoms.

Despite antioxidant defence mechanisms, cell damage from oxygen free radicals OFR is ubiquitous. OFR-related lesions that do not cause cell death can stimulate the development of cancer. At the same time, excessive amounts are harmful to humans. Free radicals are thought to be one cause of cancer, as well as the cause of some auto-immune diseases, heart diseases, neurological diseases, and the aging process in general.

Antioxidants are molecules that can safely interact with free radicals. Unlike other molecules, antioxidants can donate an electron to a free radical and still remain stable, therefore stopping the cycle A persistent and recurring way. Examples of antioxidants are:. One of the best ways to reduce free radical damage in the body, and therefore decrease your risk of breast cancer, is to increase your intake of these vitamins.
