Special Issue Information

Dear Colleagues,

This Special Issue is the second edition of a previous one, entitled “Breast Development and Cancer”.

Breast development is a complex process: breasts undergo multiple changes throughout life, from the intrauterine life to senescence. The human breast consists of parenchymal and stromal elements. The parenchyme forms a system of branching ducts eventually leading to secretory acini development, and the stroma consists mainly of adipose tissue, providing the environment for the development of parenchyma; mutual and reciprocal interactions between epithelial components and mesenchymal or stromal cells are responsible for prenatal, infant and pubertal breast development. Evidence suggests that the mesenchyme has indictive properties that lead to the local migration and changes in the cell adhesion of epithelial cells. Hormonal influences on this paracrine interaction between the mesenchyme and parenchyme are evident at all stages of development. The formation of lactiferous ducts is induced by placental hormones entering the foetal circulation; other implicated hormones include progesterone, growth hormone, insulin-like growth factor, oestrogens, prolactin, adrenal corticoids and triidothyronine.

Mammary stem cells and progenitors do not express receptors for hormones, and hormone-positive cells generally do not proliferate.

The microenvironment plays an important role in tissue homeostasis, cancer progression and metastasis.

To fully understand the defects leading to breast cancer, it is essential to decipher the mechanisms that regulate normal mammary development and morphogenesis.

Despite the considerable advancements made in the field, our understanding of the complex cascade of signals between neighbouring cells of developing tissues and the role of the matrix microenvironment is still largely lacking.

Moreover, the same general processes, from proliferation to invasion, that take place during normal mammary development, also occur in malignant disease.

The identification of mechanisms and genes that govern stem and progenitor cell expansion, or that determine daughter cell fate will be of crucial interest for understanding breast cancer diversity and ultimately improving treatment options.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

This study aims to summarize evidence from observational studies about the lifetime use of HC and the risk of BC in women of reproductive age. The PubMed, Cochrane, and EMBASE databases were searched for observational studies published from 2015 to February 2022. Meta-analyses were performed using adjusted odds ratios and relative risks with a random-effects model using the I2 statistic to quantify the heterogeneity among studies. Of the 724 studies identified, 650 were screened for title/abstract selection, 60 were selected for full-text revision, and 22 were included in the meta-analysis. Of these, 19 were case-control studies and 3 were cohort studies. The results of the meta-analysis indicate a significantly higher risk of developing BC in ever users of HC (pooled OR = 1.33; 95% CI = 1.19 to 1.49). This effect is larger in the subgroups of case-control studies (pooled OR = 1.44, 95% CI = 1.21 to 1.70) and in the subgroup of studies that strictly define menopausal status (pooled OR = 1.48; 95% CI, 1.10 to 2.00). Although our meta-analysis of observational studies (cohort and case-control) suggests a significantly increased overall risk of BC in users or ever-users of modern hormonal contraceptives, the high heterogeneity among studies (>70%) related to differences in study design, measurement of variables, confounders, among other factors, as well as publication biases should be considered when interpreting our results.
