Your Diet & Breast Cancer

A healthy diet helps your whole body, but did you know it can be good to reduce your cancer risk too?


What you eat affects your weight, and obesity raises your odds for breast cancer. If you’ve already had the disease, extra pounds can also make it more likely to return.

If you choose a healthy diet – one rich in vegetables, whole grains, chicken, and fish – you may boost your chances of living longer after breast cancer.

What are the things that can make a positive difference?

Soy-based foods such as tofu, soy milk, and edamame have chemicals called phytoestrogens, which are similar to oestrogen.

That once raised fears that they spelled trouble for women with breast cancer that uses oestrogen as fuel to grow. But the latest studies show soy doesn’t raise cancer risk — it may even lower the odds the disease will return.

Sugar is a more complicated issue as the idea that sweets “feed cancer” has been around for a long time.

A spoonful to take the edge off your coffee will not directly make cancer cells grow faster. But it’s still wise to keep an eye on how much you add to your diet as a lot of sugar on a regular basis can lead to obesity and other conditions that make cancer more likely.

Plant-based foods may lower your chances of getting breast cancer so eat more of them as researchers say this strategy especially may help protect against the most aggressive types of tumours.

Fruit and vegetables are also an important part of a diet that will help you control your weight, which is key for keeping breast cancer from coming back.

Whole grains like unprocessed wheat, rye, oats, corn, bulgur, rice, and barley when added to your diet may reduce your risk of breast cancer.

These foods have nutrients called phytochemicals that may lower the chances it will return, too. They can also help protect against cardiovascular disease — and survivors have higher odds, in part because some treatments can damage the heart.

Alcohol is also not a straightforward issue as the link between alcohol and breast cancer is murky.

Beer, wine, and spirits boost oestrogen in the body, which raises concerns about tumours that are sensitive to that hormone. Some studies say that survivors who have more than one or two drinks a week are more likely to have cancer come back, while other research says moderate drinking may be good for you.

The effects may be fairly small either way, so an occasional glass is not an issue.

Organic foods are grown without pesticides or weedkillers. One highly publicised French study found a link between these products and a lower cancer risk. But the issue is far from settled.

The most important thing, scientists agree, is to eat plenty of fruit and vegetables and to wash them carefully to remove the residue of any chemicals.

Fat has been found in some studies to play a role in the growth of breast tumours, but the research is far from clear.

Your best bet is to limit saturated fats and trans fats — which come in foods like beef, butter, cheese, ice cream, fried foods, and commercial baked goods.

When it comes to protein, go for lean kinds, such as fish and chicken.

Fibre is good for your overall health, especially your blood sugar levels, heart, and digestive tract.

You’ll get this naturally if you eat plenty of whole grains, fruit, vegetables, and legumes and some studies have suggested this type of diet can lower your odds of breast cancer. In particular, it may help protect against an aggressive type of tumour.

Vitamin D at low levels has been linked in some studies to a link between this and higher chances of breast cancer and it may also play a role in the growth of tumours.

Add it to your diet with salmon, oysters, herring, mackerel, and sardines. You can also look for milk, yoghurt, and orange juice that have it added in.

Flavonoids are chemicals you find in certain plants, and are linked to lower breast cancer odds.

The evidence is strongest for two specific types, flavonols and flavones, especially for women who are past menopause.

You can find flavonols in onions, broccoli, and tea. Flavones come in parsley, celery, and drinks with chamomile.

Carotenoids are another type of phytochemical in plant-based food linked to lower breast cancer risk. You can get it from orange, yellow, and dark green vegetables and fruit.

Look to include more carrots, pumpkin, winter squash, spinach, kale, sweet potatoes, and cantaloupe in your diet.

Phenolic compounds are types of chemicals that may lower your chances of breast cancer and in some cases slow tumour growth.

Add more to your diet in the form of garlic, green tea, soybeans, and flaxseed. Fruit and vegetables that have them include broccoli, cabbage, tomato, aubergine, cucumber, and watermelon.
