Overview
Breast cancer is the most prevalent cancer among women globally, accounting for over 2.3 million cases annually and representing a leading cause of cancer mortality.[1] Traditionally linked to genetic predispositions and environmental exposures, emerging evidence highlights the microbiome as a critical and underappreciated factor influencing breast cancer progression, immune response, and treatment outcomes.[3][x] Central to its development are mutations in tumor suppressor genes BRCA1 and BRCA2, which impair DNA repair, promote genomic instability, and increase susceptibility, particularly to aggressive subtypes like triple-negative breast cancer.[4] Screening strategies such as mammography and breast self-examination play critical roles in early detection, yet awareness and participation remain insufficient in many populations. Emerging evidence highlights the microbiome’s relevance in breast cancer, with dysbiosis in gut and oral microbiota implicated in modulating estrogen metabolism, inflammatory responses, and immune surveillance, thereby influencing tumorigenesis and treatment outcomes.[5][6][7] Understanding the microbiome signatures associated with breast cancer offers unprecedented opportunities for targeted therapies, preventive strategies, and personalized treatment in breast cancer management.
Associated Conditions
Diabetes and benign breast disease (BBD) are interconnected risk factors that influence breast cancer risk. Type 2 diabetes (T2D) increases the risk of breast cancer through mechanisms like hyperinsulinemia and the activation of the insulin-like growth factor (IGF) pathway, which promotes cell growth and inhibits apoptosis, leading to a higher likelihood of cancer development, particularly in estrogen receptor-positive breast cancer.[8]Type 1 diabetes (T1D) also elevates breast cancer risk, especially shortly after diagnosis.[9] Meanwhile, a history of BBD, especially conditions like fibroadenoma and lobular proliferation, is a known risk factor for breast cancer. Surgical treatment for certain benign conditions, such as fibroadenoma, has been shown to reduce future cancer risk.[10] These factors, along with potential microbiome disruptions, can worsen insulin resistance and influence immune function, further elevating breast cancer risk. The gut microbiome, in particular, has been shown to play a role in breast cancer development, with a reduction in short-chain fatty acid-producing bacteria like Faecalibacterium prausnitzii, which are associated with anti-inflammatory effects and maintaining metabolic health.[11][x] Dysbiosis, or an imbalance in gut bacteria, may contribute to increased systemic inflammation and other metabolic conditions that heighten breast cancer susceptibility.[12] Thus, managing diabetes, monitoring BBD, and understanding the role of the microbiome are crucial for reducing breast cancer risk.
Causes
Breast cancer is thought to arise from a multifactorial interplay of genetic, environmental, and hormonal factors, with up to 70% of cases having unknown etiology. However, recent studies find that dysbiosis—characterized by a significant overgrowth of Proteobacteria and reduced diversity of beneficial taxa like Bacteroidetes and SCFA-producing bacteria like Faecalibacterium prausnitzii, plays a critical role by disrupting estrogen metabolism, promoting inflammation, and altering the tumor microenvironment in breast cancer.[13][x] Evidence suggests that frequent antibiotic use may contribute to breast cancer risk by promoting Proteobacteria blooms as well as Escherichia coli and Klebsiella sp., which are enriched in the breast cancer patient, amplifying systemic inflammation and immune suppression.[14][x][15] Microbial dysbiosis, both local and systemic, has significant implications for breast cancer progression, with some literature even proposing that antibiotics may potentially play a causal role in the condition.[16][x]
Diagnosis
Currently, breast cancer diagnosis relies heavily on imaging (mammography, ultrasound) and histopathological confirmation. However, advancements in microbiome research suggest that microbial signatures, including shifts in gut and breast tissue microbiota, could serve as non-invasive diagnostic biomarkers. For instance, altered ratios of Firmicutes to Bacteroidetes in the gut and specific microbial markers in breast tissue (e.g., Bacteroides fragilis, Methylobacterium radiotolerans) offer promising diagnostic potential. Integrating microbiome analyses into routine diagnostics could improve early detection, especially for aggressive subtypes like triple-negative breast cancer. [17]
Primer
The interplay between the microbiome, immune modulation, and hormone metabolism highlights the microbiome’s central role in breast cancer pathogenesis. Dysbiosis contributes to systemic inflammation, immune escape, and tumor growth. For example, reductions in SCFA production impair anti-inflammatory pathways, while overgrowth of specific taxa drives estrogen metabolism disruptions, fueling hormone receptor-positive cancers. Addressing these microbial imbalances through targeted interventions may enhance therapeutic outcomes. Additionally, the activity of beta-glucuronidase, an enzyme involved in estrogen conjugation, is linked to the microbial dysbiosis observed in women with a history of breast cancer. [18]
Metallomic Signatures
Metallomic signatures play an important role in understanding breast cancer, with recent research highlighting how heavy metals and metabolites contribute to the progression of the disease.[19] A growing body of evidence suggests that exposure to heavy metals, including copper (Cu), cadmium (Cd), and zinc (Zn), can significantly influence breast cancer development by altering cellular pathways, including reactive oxygen species (ROS) production.[20] These metals can induce cancer progression by mimicking or disrupting essential metabolic pathways, influencing cell growth and survival. Studies have shown that increased concentrations of Cu and Cd, combined with lower levels of Zn, are associated with breast cancer patients compared to healthy controls.[21][22] Cadmium’s estrogenic effects are implicated in promoting breast cancer cell proliferation, suggesting a potential role in hormone-sensitive breast cancer. This is because cadmium, a heavy metal, can mimic the effects of estrogen by binding to estrogen receptors and activating them.[23] This activation can lead to increased cell growth and proliferation, contributing to the development of hormone-sensitive breast cancer.
What are the metallomic signatures of Breast Cancer?
Copper (Cu)
Copper is an essential heavy metal in the body, playing a crucial role in several enzymatic processes and maintaining normal cellular function. However, elevated levels of Cu have been linked to breast cancer development, particularly through the induction of oxidative stress and dysregulation of various cellular processes. Studies have indicated that high copper concentrations in both serum and tumor tissue are associated with increased breast cancer risk.[24] Copper influences angiogenesis, the process by which new blood vessels are formed, which is critical for tumor growth and metastasis.[25] It also activates several signaling pathways, including those related to cell proliferation and survival, thus contributing to tumor progression.
Cadmium (Cd)
Cadmium is a well-known environmental toxicant and a suspected carcinogen that has been consistently associated with breast cancer. Studies have shown that cadmium mimics the action of estrogen by binding to estrogen receptors (ER), particularly in estrogen-sensitive tissues such as the mammary glands.[26] This estrogenic effect promotes the proliferation of breast cancer cells, especially in hormone receptor-positive breast cancers.[27] Epidemiological evidence supports the notion that chronic exposure to cadmium, particularly through smoking or polluted environments, increases the risk of developing breast cancer.[28] Moreover, high cadmium levels have been found in breast cancer tissues, which further supports its role in disease development. The cadmium-induced carcinogenic mechanism is also believed to involve oxidative stress, DNA damage, and the disruption of DNA repair pathways, which can lead to mutations and tumorigenesis.[29]
Zinc (Zn)
Zinc is an essential trace element that plays a critical role in immune function, DNA synthesis, and cell division. Interestingly, while low zinc levels are commonly observed in individuals with breast cancer, the relationship between zinc and breast cancer risk is complex.[30] A meta-analysis indicated that low levels of zinc in serum and tissues were correlated with breast cancer cases.[31] Zinc deficiency may also impair immune responses and increase oxidative stress, creating an environment conducive to cancer development. Zinc’s involvement in DNA repair and apoptosis makes it a key player in tumor suppression.[32][33] Zinc’s role in the proper functioning of metallothioneins (MTs), proteins that regulate metal homeostasis and protect against oxidative stress, is also important in the context of breast cancer.[34]
Manganese (Mn)
Manganese is another essential metal involved in various physiological processes, including enzyme activation and antioxidant defense. However, like other heavy metals, its dysregulated levels have been associated with breast cancer. Studies have found that elevated manganese concentrations in tissues and blood are linked to increased breast cancer risk.[35] Manganese plays a role in the ROS pathway, which is critical in cancer biology as it contributes to cell survival, migration, and invasion. Manganese is involved in the activation of several oncogenic pathways, including those related to growth factor signaling. The imbalance of manganese metabolism may lead to increased ROS production, further driving the progression of breast cancer.[36]
MMAs
The Major Microbial Associations (MMAs) for breast cancer can be identified as taxa that are consistently reported as being significantly altered and biologically relevant to disease pathogenesis. The MMAs for breast cancer reflect key microbial patterns that are enriched or depleted in affected patients, revealing functional dysbiosis contributing to disease progression. Enriched microbes, such as Proteobacteria and Bacteroides, drive pro-inflammatory pathways and systemic effects, exacerbating cancer-related outcomes. Conversely, depleted microbes, including Faecalibacterium prausnitzii and Clostridiales, represent a loss of anti-inflammatory and protective functions critical for maintaining gut and systemic health.[37][x] Additionally, microbes like Prevotella amnii and Lactobacillus vaginalis highlight specific effects on estrogen metabolism and mucosal immunity, which are especially relevant in postmenopausal breast cancer. Understanding these microbial associations offers insights into potential microbiome-targeted interventions and biomarkers for breast cancer.
What are the Major Microbial Associations (MMAs) for breast cancer
Gut Microbiome and Breast Cancer
Alterations in the gut microbiome composition have been linked to breast cancer development. In postmenopausal women, breast cancer patients exhibit a distinct gut microbiota compared to healthy controls, with an increase in microbial diversity.[38] Specific taxa such as Escherichia coli, Klebsiella sp., Prevotella amnii, and Enterococcus gallinarum are significantly enriched in breast cancer patients, while beneficial bacteria like Lactobacillus vaginalis are reduced. These alterations may affect systemic inflammation, immunity, and metabolic processes, contributing to cancer susceptibility.[39][40]
Premenopausal vs. Postmenopausal Breast Cancer
Studies on premenopausal breast cancer patients reveal reduced alpha diversity in the gut microbiota, with significant differences in microbial abundance between cases and controls. Notably, Bacteroides fragilis is found in higher abundance in premenopausal breast cancer patients, whereas Klebsiella pneumoniae is more prevalent in postmenopausal patients.[41] This suggests that the gut microbiota plays a role in breast cancer across menopausal statuses, with distinct microbial signatures observed in different age groups.
Breast Tissue Microbiota
The microbiota within breast tissue itself shows significant changes in cancerous and adjacent tissues compared to healthy tissues. For example, bacteria such as Methylobacterium radiotolerans are enriched in tumor tissues, while Sphingomonas yanoikuyae is more abundant in adjacent normal tissues.[42] This microbial dysbiosis in the breast may influence local immune responses and the progression of cancer.
Gut and Oral Microbiota Correlations
There is a strong correlation between gut and oral microbiota in breast cancer patients, which is weaker in healthy controls. The relative abundance of specific oral microbes like Porphyromonas is inversely correlated with gut bacteria such as Bacteroides in breast cancer patients, highlighting the interaction between the microbiomes of different body sites.[43] The gut and oral microbiota’s interrelationship in breast cancer patients suggests that microbial imbalances may not be confined to one body site.
Tumor Characteristics and Gut Microbiome
Associations between the gut microbiome and tumor characteristics such as HER2 status have been observed. Specifically, HER2+ breast cancer patients show lower microbial diversity and an altered balance of gut bacteria compared to HER2− patients. Additionally, high body fat and early menarche are linked to distinct changes in the gut microbiota, which may contribute to cancer risk.[44]

Interventions
The validation process aligns microbiome-targeted interventions (MBTIs) with microbial dysbiosis correction and clinical improvements. Breast cancer treatments may benefit from incorporating strategies to restore microbial balance, such as dietary SCFA supplementation, probiotics, and precision microbiome therapies.
Class | Interventions | Mechanisms of Action | MBTI Status |
---|---|---|---|
Pharmaceutical | Tamoxifen | Selectively binds estrogen receptors (ER), preventing estrogen from binding to the receptor, inhibiting cancer cell proliferation. It also downregulates estrogen-dependent gene expression, preventing tumor growth in estrogen receptor-positive breast cancers.[45][46] | Validated |
Non-Pharmaceutical | Exercise Therapy | Increases circulation, reduces systemic inflammation, enhances immune function, and helps manage cancer-related fatigue by promoting the release of endorphins.[47] | Promising |
Fecal Microbiota Transplantation (FMT) | FMT directly targets the gut microbiome by reintroducing a healthy microbiota, thus potentially altering microbial-related immune pathways. It has been shown to improve chemotherapy efficacy by restoring a more favorable microbial composition that supports anti-tumor immune responses.[48][49] | Experimental | |
Supplements | Vitamin D | As vitamin D downregulates ERα expression via inhibition of NF-κB, it may increase the sensitivity to tamoxifen through induction of functional ERα in ER-negative cancer cells. Vitamin D combined with tamoxifen may be effective in tamoxifen-resistant tumors, and its concurrent use with aromatase inhibitors may be another suitable therapeutic option.[50][51][52] | Validated |
Short-Chain Fatty Acid (SCFA) | SCFAs play a crucial role in maintaining gut health by promoting gut barrier integrity, regulating immune responses, and reducing systemic inflammation. SCFAs, especially butyrate, are known to inhibit histone deacetylases (HDACs), leading to changes in gene expression that promote apoptosis (programmed cell death) and inhibit tumor cell proliferation.[53][54] | Under Investigation | |
Flavonoids | Flavonoids, including apigenin, quercetin, and genistein, have been shown to inhibit estrogen receptor signaling, suppress aromatase activity, and reduce estrogen synthesis within cancer cells. They also induce apoptosis and inhibit cell proliferation.[55] | Promising Candidate | |
Nutritional Therapy | Probiotics | Probiotics produce short-chain fatty acids (SCFAs) that support gut health, enhance immune function, and help in reducing systemic inflammation. These actions can influence cancer progression, as inflammation and immune dysregulation are often linked to tumor development.[56][57][x][58] | Promising Candidate |
High-Fiber Diet | Regulates blood sugar and insulin levels, which affect breast cancer risk and prognosis. Fiber promotes the growth of beneficial gut bacteria like Bifidobacterium and Lactobacillus.[59][x] | Validated | |
Drug Repurposing | Aspirin | Inhibits COX-2, reducing inflammation and tumor growth by suppressing pro-inflammatory cytokines.[60][61] | Promising Candidate |
Metformin | Regulates insulin levels, inhibits mTOR, and reduces cell proliferation in cancer cells.[62] | Promising Candidate |
STOPs
The STOPs initiative advocates for the careful re-evaluation of common clinical practices that could potentially disrupt the microbiome and increase breast cancer risk. It emphasizes the significant role the microbiome plays in modulating immune responses, systemic inflammation, and estrogen metabolism. Recent studies suggest that specific practices, such as the routine use of chlorhexidine mouthwash, prolonged estrogen supplementation, and increased use of antibiotics, can negatively impact the microbiome, contributing to dysbiosis (microbial imbalance) that might promote breast cancer progression, particularly hormone receptor-positive and chemoresistant breast cancers.[63][x][64] Chlorhexidine is widely used for oral hygiene but has been found to alter the oral microbiome, reducing microbial diversity and promoting the overgrowth of potentially harmful species like Proteobacteria.[65] These shifts in the oral microbiome are linked to systemic inflammation and estrogen metabolism alterations, which could exacerbate hormone-driven breast cancer.
STOP | Microbiome Impact | Breast Cancer Risk |
---|---|---|
Chlorhexidine Mouthwash | Reduces oral microbial diversity, increases Proteobacteria, decreases beneficial microbes like Fusobacterium and Porphyromonas. | Potential causal link to breast cancer through oral and gut dysbiosis, influencing estrogen metabolism and immune function. |
FAQs
How does the gut microbiota influence breast cancer subtypes?
The gut microbiota plays a critical role in shaping systemic hormone levels, inflammation, and immune responses, all of which are linked to breast cancer subtypes. For example, hormone receptor-positive (HR+) breast cancers are influenced by the gut microbiota’s role in estrogen metabolism.rnrnDysbiosis can increase β-glucuronidase activity, leading to elevated circulating estrogen levels, which fuel HR+ tumors. In contrast, triple-negative breast cancers (TNBC) are more dependent on immune surveillance, and gut dysbiosis can impair anti-tumor immunity. Specific microbial taxa, such as u003cemu003eFaecalibacterium prausnitziiu003c/emu003e and u003cemu003eBacteroides fragilisu003c/emu003e, exhibit protective roles by producing anti-inflammatory short-chain fatty acids (SCFAs) and modulating the tumor microenvironment.rnrnu0026nbsp;
Are probiotics effective in improving treatment outcomes for breast cancer?
Probiotics have shown potential to improve breast cancer treatment outcomes by restoring gut microbiota diversity, reducing inflammation, and enhancing the efficacy of therapies. Studies suggest that probiotics can mitigate chemotherapy and radiation-induced dysbiosis, improving tolerance to treatment and reducing side effects like diarrhea and mucositis.rnrnAdditionally, probiotics may enhance immune responses, which are critical for the efficacy of therapies such as immune checkpoint inhibitors. However, the use of probiotics remains an emerging area, and their clinical efficacy in breast cancer requires further validation through large-scale trials.
Can microbiome-targeted interventions reduce chemotherapy side effects?
Yes, microbiome-targeted interventions, including probiotics, prebiotics, and dietary modifications, can help alleviate chemotherapy side effects. For instance, supplementation with SCFA-producing bacteria, like u003cemu003eFaecalibacterium prausnitziiu003c/emu003e, has been associated with reduced inflammation and improved gut barrier function, which can mitigate chemotherapy-induced gastrointestinal toxicity. Fecal microbiota transplantation (FMT) has also shown promise in restoring microbiota diversity and reducing treatment-related side effects. Emerging research indicates that maintaining a healthy microbiome can reduce weight gain, neurotoxicity, and inflammation associated with breast cancer therapies.
