Article Synopsis
  • Alcohol consumption is linked to an increased risk of female breast cancer, making it important to understand how cessation impacts this risk.
  • A recent meta-analysis found that women who stop drinking may have a reduced risk of estrogen receptor positive (ER+) breast cancer (RR=0.88), while there is no significant risk reduction for estrogen receptor negative (ER-) breast cancer (RR=1.23).
  • The study suggests that quitting alcohol may lower the risk of developing ER+ breast cancer, but more research is needed to explore how long cessation effects last.

The identification of premalignant lesions in solid tumors such as colorectal and cervical cancer has led to the development of highly effective population-wide screening programs for these malignancies. Although precursor clinical states are not well-established for most hematologic malignancies, multiple myeloma is a notable exception. Virtually all patients with multiple myeloma first develop monoclonal gammopathy of undetermined significance (MGUS), an asymptomatic but easily detectable condition.

Concerns persist about the potential impact of prenatal exposure to bisphenols (BP) and their replacement analogues on childhood asthma and allergies. Previous studies on single and small cohorts had limited statistical power, few investigated analogues BPF and BPS, and even fewer examined atopic outcomes. Our objective was to assess whether prenatal exposures to individual environmental bisphenols (BPA, BPF, BPS) influence risk of childhood asthma, allergic rhinitis, and atopic dermatitis.

Background: Mycobacterium tuberculosis complex (MTBC) species evolve slowly, so isolates from individuals linked in transmission often have identical or nearly identical genomes, making it difficult to reconstruct transmission chains. Finding additional sources of shared MTBC variation could help overcome this problem. Previous studies have reported MTBC diversity within infected individuals; however, whether within-host variation improves transmission inferences remains unclear.
