Worldwide, more than 10 million people are diagnosed with cancer every year. Until recently it was believed that cancer is largely caused by genetic mutations; however, new research from Stony Brook University in the US indicates that up to 90% of cancers could be avoided by living a healthier lifestyle. On World Cancer Day, discover which foods and drinks could reduce your cancer risk.

One apple a day really can keep the doctor away. According to the Prevent Cancer website, eating antioxidant-rich apples on a daily basis has been associated with a lower risk of lung and colon cancers, while the phytochemicals in apples (including quercetin) have been shown to quash cancerous breast tumors.

Beans, particularly kidney and red beans, are an exceptional source of antioxidants, they're full of fiber, and are a source of inositol hexaphosphate (also called IP6) which is being studied for its potential to combat cancer. Beans could reduce the likelihood of death from breast, colon, gastric and prostate cancer.

Berries, especially blueberries, are excellent sources of cancer-busting flavonoids and antioxidants, which mop up the free radicals in the body that damage cells. And there’s good news for breast cancer sufferers – blueberries are thought to enhance the positive effects of the drug tamoxifen.

Research into coffee and cancer has had varying results. A 2015 study by Sweden’s Lund University showed that women who drank more than two cups of coffee a day had smaller breast tumors, and halved their risk of cancer returning if treated with tamoxifen. However, other reports indicate that coffee affects people – and their particular cancer – differently. Coffee consumption, weight and age play a part.

Garlic is a powerful anti-cancer food. Population studies have shown an association between garlic intake and a reduced risk of certain cancers, especially those that affect the digestive system, such as the stomach and colon, and the breasts. Garlic can block cancer-causing substances, may stop cancer cells multiplying, and aid DNA repair.

Bell peppers score highly on the flavonoids and carotenoids rich list (known to protect against cancer). The antioxidant lycopene, which is found in tomatoes and is thought to prevent prostate cancer, is also present in red peppers.
