The Functional Medicine Perspective on Breast Cancer Prevention

Minimizing risk factors, strengthening your immune system, and equipping your body with the means to combat free radicals can collectively lower the probability of breast cancer development.

Functional testing proves invaluable in assessing your oestrogen type ratios and evaluating your genetic predisposition to oestrogen production.

Functional medicine believes that health issues originate from imbalances within your body. It regards you as an integrated whole rather than a collection of isolated components, and through comprehensive examination, it strives to unveil the underlying causes of your health issues.

Therefore I recommend the ‘DNA Oestrogen Test’ which includes 11 genes involved in oestrogen biosynthesis, oestrogen metabolism, and phase I and phase II detoxification, providing information to guide personalised diet, lifestyle, hormone, and nutraceutical recommendations.

Approximately 80% of breast cancer occurs in women with no family history.  Oestrogen affects the function of a number of target tissues and research has shown that an increased lifetime exposure to oestrogen is a strong risk factor in the development of breast cancer.

DNA Oestrogen tests for gene variants that have been shown to have an impact on how oestrogen is metabolised. Guiding the personalisation of diet, hormone and nutritional supplement recommendations, based on the insight gained from the DNA Oestrogen test, to improve oestrogen metabolism is of benefit to men and women who suffer from numerous oestrogen-dominant conditions and who have higher lifetime exposure to oestrogens, oestrogen metabolites and other carcinogens.

Clinically recommended for:
• Men or women with a strong family history of breast, ovarian, colon or prostate cancer
• Women who suffer from oestrogen-dominant conditions such as endometriosis, premenstrual syndrome and uterine fibroid tumours
• Women considering oral contraceptives, hormone replacement therapy or bio-identical hormone supplementation
• Women who are considering in vitro fertilisation or who have been diagnosed with oestrogen  receptor-positive breast cancer
The DNA Oestrogen Test Report provides:
• The level of impact of any genetic variants identified
• An explanation of their impact on oestrogen metabolism
• Appropriate nutritional and lifestyle recommendations to support healthy oestrogen metabolism

Analytes measured:

CYP1A1:  A phase I cytochrome P450 enzyme that converts environmental pro-carcinogens into reactive intermediates that have carcinogenic effects. It is further involved in the oxidative metabolism of oestrogens.

CYP1B1:  Catalyses the 4-hydroxylation of oestradiol and active polycyclic aromatic hydrocarbons (PAHs)  and arylamines.CYP17A:  Catalyses reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids as an integral part of the oestrogen metabolism pathway.

MnSOD:  Provides anti-oxidant activity within the cell, necessary for decreasing oxidative damage caused by reactive oestrogen metabolites.

GSTM1:  Responsible for the removal of xenobiotics, carcinogens, and products of oxidative stress, which include reactive oestrogen metabolites.

GSTT1:  A member of a super family of proteins that catalyse the conjugation of reduced glutathione, and is responsible for removal of reactive products of oestrogen metabolism.

COMT:  Influences the levels of certain hormones and is involved in the methylation and inactivation of catechol oestrogens.

MTHFR:  MTHFR is a key enzyme in the folate metabolism pathway – directing folate from the diet either to DNA synthesis or homocysteine re-methylation. Decreased MTHFR enzyme activity has been associated with increased premenopausal breast cancer risk with long duration of oestrogen exposure.

SULT1A1:  Involved in the inactivation of oestrogens and bio-activation of heterocyclic amines and polycyclic aromatic hydrocarbons.

NQO1:  Quinone Reductase is primarily involved in the detoxification of potentially mutagenic and carcinogenic quinones derived from tobacco smoke, diet and oestrogen metabolism.

Factor V:  Factor V Leiden gene mutation is characterized by a poor anticoagulant response to Activated Protein C and an increased risk for venous thromboembolism.
