Soy does not increase breast cancer risk

It has sparked numerous debates. Is there a connection between soy and breast cancer?

Soy contains isoflavones, which are plant oestrogens.

High oestrogen levels have been linked to an increased risk of breast cancer.

However, studies show that soy products don't contain high enough levels of oestrogen to increase the chances of developing breast cancer.

Dr Dawn Mussallem, a lifestyle medicine expert at Mayo Clinic, says consuming soy products in moderation can be beneficial.

Many people enjoy eating soy products like tofu, soy nuts and edamame.

Dr Mussallem says the plant-based protein doesn't increase your chance of developing breast cancer.

"For years, I've been trying to dispel the myth about soy and breast cancer. And it seems that the message still isn't out because almost every day, every patient I see is worried about consuming soy products," says Dr Mussallem.

Soy is packed with isoflavones, which is a type of plant oestrogen (phytoestrogen) known for its beneficial properties.

It has a similar chemical structure to human oestrogen, but soy binds to the oestrogen receptors on breast tissue differently, potentially acting as a tumour suppressor.

"Soy consumption after a breast cancer diagnosis not only is a great way for you to get a plant-based protein, it also improves your breast cancer outcomes," says Dr Mussallem.

It is more important to avoid ultraprocessed foods, including processed meat, and limit intake of red meat and high-fat dairy.

Eating a wide variety of colourful vegetables and fruits, whole grains, legumes, nuts, and seeds can be helpful in preventing and surviving breast cancer. – Mayo Clinic News Network/tribune News Service
