The World Cancer Research Fund said that many people do not know that there is a lot they can do to prevent cancer, and are especially unaware of the links between diet,body weight and physical activity

The charity said it is working to dispel the myth that all cancers are unavoidable.

Boost Your Anti-Cancer Diet
Vitamin D(01 of08)

Studies have found that people who have higher levels of vitamin D have significantly lower rates of breast, ovarian, renal, colon, pancreatic, aggressive prostate, and other cancers. Researchers have even predicted that raising vitamin D levels in the United States and Canada would prevent 58,000 people from getting breast cancer and 49,000 from getting colorectal cancer. However, Americans are woefully short on this essential nutrient. We get more than 90 per cent of vitamin D from sunshine, but people are avoiding the sun for fear of getting skin cancer, Dr. Teitelbaum says. “Avoid sunburn, not sunshine,” he says. And take a vitamin D nutritional supplement. He recommends that everyone take 1,000 to 2,000 international units of vitamin D a day, which you can find in a good multivitamin. (credit:Alamy)
Curcumin(02 of08)

Curcumin has killed cancer cells in the laboratory, shrunk tumors in animals, and helped prevent several forms of cancer from developing in animal studies. “Curcumin is a pretty remarkable herb,” Teitelbaum says. There are more than 1,000 studies showing that it’s effective for cancer, he says. But if you’re not eating foods made with curry every day (because curcumin is derived from turmeric), you’re probably not getting enough for cancer protection, he says. Should everyone take a dietary supplement? It’s probably only necessary if you have a strong family history of cancer, Teitelbaum says. Be sure to find a supplement specifically designed for easy absorption, such as the product Curamin. (credit:Alamy)
Vitamin B (03 of08)

Some research has shown that B vitamins, including folic acid (vitamin B9), can lower the risk for some cancers, but the research hasn’t been conclusive. Observational studies have found that people who get more folic acid may be less likely to get colon cancer, especially compared to people who are deficient in folic acid, and that getting vitamin B6 may lower the likelihood of getting colorectal cancer. But researchers haven’t done large clinical trials on these vitamins. The best option is to choose a good multivitamin that includes B vitamins rather than individual supplements. (credit:Alamy)
Green Tea(04 of08)

Studies done in the laboratory suggest that some compounds in antioxidant-rich green tea may help stop cancer cells from growing by cutting off their blood supply. One study from China found that people who drank green tea and did not smoke had a lower risk of getting esophageal cancer than those who didn’t drink green tea, but the results from other studies have been mixed. “It’s not the first place I reach to in terms of anti-cancer effect,” Teitelbaum says. But there are other reasons to sip: It lowers anxiety and heart attack risk, he says. (credit:Alamy)
Selenium(05 of08)

In areas of the world where the soil has high levels of selenium, there are significantly fewer deaths from cancer, including lung, breast, colon, ovarian, cervical, bladder, pancreatic, and esophageal cancers. However, clinical trials that have looked at selenium’s role in cancer prevention have been mixed. Because your body only needs a small amount of this mineral, the American Cancer Society recommends eating a healthy diet with plenty of fruits and vegetables rather than taking selenium in nutritional supplements. You can get selenium from Brazil nuts, seafood, whole grains, cereal, meat and poultry, kidney, and liver. (credit:Alamy)
Garlic (06 of08)

Eating garlic may lower your risk for breast, colon, esophageal, pancreatic, and stomach cancers, according to preliminary studies. When researchers looked at the results of seven population studies, they found that those with higher amounts of garlic in their diet had lower risk for stomach and colorectal cancer. But the results of clinical trials have been mixed, and researchers don’t know how much garlic you may need for protection. The World Health Organization recommends that people get about a clove of garlic a day in their diet. (credit:Alamy)
Fish Oil (07 of08)

Truth be told, fish oil’s strength is not cancer prevention, Teitelbaum says. Some research has shown that women who eat fish twice a week have a lower risk for endometrial cancer, but in general the research looking at cancer protection hasn’t shown much of a link. However, fish oil can do so much for your health, including helping to prevent heart disease or stroke and lowering rates of depression. There’s good reason to focus on getting fish in your diet and consider taking fish oil nutritional supplements. (credit:Alamy)
Beta Carotene(08 of08)

Animal studies have suggested that vitamin A (which includes beta carotene) could shrink tumors, slow down the growth of tumors, and enhance cancer treatments. However, getting too much beta carotene or vitamin A can be toxic. When smokers took vitamin A dietary supplements, their risk of dying from lung cancer and heart disease increased. If you take a high dose of beta carotene, you can cause relative deficiency of other nutrients in the body, Teitelbaum says. For that reason, don’t get more than 5,000 international units of beta carotene a day. (credit:Alamy)

A new WCRF poll, released to mark World Cancer Day, found that 49% of people do know know that diet can affect people's risk of getting cancer.

Two thirds of the 2,000 British adults polled did not know about the links between cancer and physical activity and 59% were unaware of the correlation between cancer and body weight.

And more than a third of people (34%) believe that the chances of getting cancer are mainly due to a family history of the disease even though only five to 10% of cancers are linked to inherited genes.

The charity is working alongside the Union for International Cancer Control (UICC) to encourage people to take steps to reduce the risk of developing cancer, including:

  • Eating a healthy diet with lots of vegetables, fruit, pulses and whole grains
  • Maintaining a healthy weight with a BMI between 18.5 and 25.
  • Bring physically active for at least 30 minutes every day.

WCRF general manager Amanda McLean said: "On World Cancer Day 2014 it's very alarming to see that such a large number of people don't know that there's a lot they can do to significantly reduce their risk of getting cancer.

"We would like all sectors of society - including the government, manufacturers, retailers and charities - to work together to raise cancer prevention awareness.

"In the UK, about a third of the most common cancers could be prevented through being a healthy weight, eating a healthy diet and being regularly physically active. These results show that many people still seem to mistakenly accept their chances of getting cancer as a throw of the dice. But by making lifestyle changes today, we can help prevent cancer tomorrow."
