Studies

This study says Broccoli sprouts are known to possess anti-cancer properties such as chemopreventive properties against gastrointestinal, breast, lung, bladder, prostate, and other cancers. The reported data indicates that broccoli could be a potent inhibitor of cancer development and progression and can be used alone or in combination with other isocyanates or conventional anti-cancer medications.

In this study of 239  bladder cancer patients … intake of raw cruciferous vegetables was significantly associated with reduced disease-specific (57% reduction) and overall mortality (43% reduction), a result largely driven by raw broccoli intake.

According to Nutritionfacts.org, Broccoli sprouts, germinated seeds of broccoli that have a radishy taste and look similar to alfalfa sprouts, may improve survival rates of bladder cancer patients, help protect skin cells from sun damage, and potentially boost liver detoxification. They also been shown to suppress the ability of breast cancer stem cells to form tumors.

This study found that broccoli sprout consumption slowed prostate cancer formation and decreased cancer severity…

This study says: This study shows that sulforaphane inhibits breast cancer stem cells in vitro and in vivo, which provides a strong rationale for future clinical evaluation of sulforaphane or extract of broccoli/broccoli sprouts for breast cancer chemoprevention. 

This study concluded:  the present study showed that sulforaphane inhibited cancer stemness through miR-200c induction, which resulted in the inhibition of the self-renewal, metastasis, and tumor initiation properties of OSCC-CSCs [Oral Squamous Cell Carcinomas – Cancer Stem Cells].

This 2019 study found:
Fifteen capsules with pulverized broccoli sprouts were administered daily for up to 1 year. Twenty-nine patients were included in the treatment group and 11 patients were in the placebo group; these patients were followed for up to 1 year… Compared to those of the placebo group, the mean death rate was lower in the treatment group during the first 6 months after intake…and Kaplan-Meier analysis revealed a higher survival rate.

Note:
Broccoli sprouts are 100 times better at providing sulforaphane than the mature broccoli.
