For the study, scientists tested the effects of sulforaphane in experiments involving mice and cell cultures.
They then used several established methods to assess the number of cancer stem cells in the tumors.
These measures showed a marked decrease in the cancer stem cell population after treatment with sulforaphane, with little effect on the normal cells.
Cancer cells from mice treated with sulforaphane were also unable to generate new tumors. The researchers then tested sulforaphane on human breast cancer cell cultures in the lab, finding similar decreases in the cancer stem cells.
Researchers are currently developing a method to extract and preserve sulforaphane.
The concentrations of sulforaphane used in the study were higher than what can be achieved by simply eating broccoli. However, broccoli is a highly valuable addition to the diet because it is an excellent source of Vitamin C and also provides other beneficial nutrients like Vitamin A and folic acid. There are also numerous studies that have linked the sulfur-containing compounds found in broccoli to fighting breast and prostate cancers.
