Study Suggests that Soy May Help with Radiation Cancer Treatment

Soy products are loaded with isoflavones – a compound whose health benefits are widely disputed. Isoflavones have been hailed for helping alleviate menopause symptoms to reducing cancer risk, but are also changed with inhibiting thyroid function and changing the menstrual cycles of women.

This week, soy products got another tally in the ‘beneficial’ column.

A new study shows that a component in soybeans increases radiation’s ability to kill lung cancer cells, which was published in the April issue of the journal for the International Association for the Study of Lung Cancer.

“These natural soy isoflavones can sensitize cancer cells to the effects of radiotherapy, by inhibiting survival mechanisms which cancer cells activate to protect themselves,” Hillman said. “At the same time, soy isoflavones can also act as antioxidants in normal tissues, which protect them against unintended damage from the radiotherapy.

In the study, it was demonstrated that the isoflavones help radiation kill cancer cells by blocking the DNA repair mechanisms in cancer cells, which are only activated in the cancer cells when they are exposed to the damaging radiation.

  1. Thanks for this wonderful information. I hope that future researches will help clear out the doubts of these critics. Now, soy products are definitely going to be on my shopping list.

  2. That’s interesting news, though is it only beneficial for lung cancer patients? A big part of me wishes I was proactive in finding alternative medicine when my mother was alive and diagnosed with cancer, I wonder if it could have helped at all.

      They only studied lung cancer patients, so they could only make conclusions about lung cancer. I imagine that in the future they will look at other types of cancer as well. In the mean time, soy products can be incorporated into most people’s diets, provided they aren’t allergic, so can’t imagine a doctor saying there would be any harm in trying to add soy into a cancer patient’s diet.
