Study: Sulforaphane: EXTRA in breast cancer management!

Preventive, supportive and therapeutic use of sulforaphane in cancer

Breast cancer is the most common cancer diagnosis in women, with treatment options including surgery, chemotherapy, hormone therapy and immunotherapy. Sulforaphane EXTRA, activated by the enzyme myrosinase, is a biochemical substance and an original dual-component nutraceutical.

Sulforaphane is a natural isocyanate found in broccoli, Brussels sprouts and other cruciferous vegetables. It is gaining attention for its role in preventing, supporting treatment and reducing the risk of recurrence of breast cancer.

1. Breast cancer prevention

Sulforaphane EXTRA can protect cells from carcinogenic processes in several ways:

• Activation of the Nrf2 pathway: Sulforaphane stimulates the expression of antioxidant and detoxification enzymes that neutralise free radicals and eliminate carcinogenic substances【1】【2】.
• Inhibition of epigenetic changes: Sulforaphane regulates histone deacetylation and DNA methylation, thereby reducing the expression of genes associated with tumour progression【3】.
• Reduction of inflammation: Chronic inflammation promotes the development of cancer. Sulforaphane suppresses pro-inflammatory cytokines such as IL-6 and TNF-α, thereby reducing the risk of tumour development【4】.

Practical recommendation: For women at high risk of breast cancer (e.g., BRCA1/BRCA2 mutations), regular consumption of broccoli or sprouts or supplements containing sulforaphane is recommended as part of prevention.

2. Support for treatment during active diagnosis

Sulforaphane EXTRA may support traditional cancer treatment through the following mechanisms:

• Increases the effectiveness of chemotherapy and radiotherapy: Increases the sensitivity of cancer cells to treatment and protects healthy tissue from damage【5】【6】.
• Suppression of angiogenesis: Inhibits the formation of new blood vessels needed to nourish the tumour, thereby limiting its growth【7】.
• Apoptosis induction: Activates programmed cell death in tumour cells without damaging healthy cells【8】.

Practical recommendation: During treatment, it is important to consult your oncologist about taking sulforaphane to take into account possible interactions with your treatment.

3. Recidivism management

After treatment and in patients at risk of recurrence, sulforaphane may:

• Support the immune system: Activates natural killer cells (NK cells) and cytotoxic T lymphocytes, which eliminate residual cancer cells【9】.
• Regulate oestrogen metabolism: Reduces tissue exposure to carcinogenic oestrogen metabolites【10】.

Practical recommendation: Patients in remission can take sulforaphane as part of an anti-cancer diet along with regular health monitoring.

4. Dosage and application

• Natural sources: Daily consumption of 200–400 g of broccoli, cabbage or sprouts provides the necessary dose of sulforaphane.
• Supplements: High-quality supplements and nutraceuticals, such as Sulforaphane EXTRA, containing 200 mg of sulforaphane with the enzyme myrosinase, can be an effective alternative, especially when taken in an enteric-coated form, which increases bioavailability.
