The presence of heavy metals (HMs) on Earth is essential to all forms of life. These metals are essential for plant and animal development but can have numerous negative effects on the living environment. In this review, we looked at where HMs come from, why they are harmful, and how they affect plants. Articles indexed in Google Scholar, PubMed, Research Gate, Science Direct, and a few books on heavy metals were consulted for this study. Heavy metals are essential for plant development and growth. According to this analysis, the hazardous effects of HMs are on the rise all throughout the globe, and this trend may be attributed mostly to human activity. Because of its impact on agricultural productivity and environmental changes, soil pollution caused by HMs is among the most crucial elements. Plants have evolved very sophisticated defense systems to deal with these environmental challenges. The threat that HM stress poses to plants has attracted a lot of attention worldwide because it could stunt agriculture’s long-term expansion. In spite of their importance for plants, this study found that HMs pose a significant threat to plant life. The novelty of this review lies in its detailed examination of both the beneficial and detrimental roles of HMs, providing a balanced perspective often overlooked in current literature. The significance of this work is underscored by its potential to inform sustainable agricultural practices and environmental management strategies, as it highlights the delicate balance required to harness the benefits of HMs while mitigating their risks. Despite their necessity for plant development, this review underscores the significant risks HMs pose to plant health and ecosystems.Less than 10 cases have been reported in the literature of the association of germline BRCA1 and Squamous cell Carcinoma – the esophagus. The article focuses on the probable pathogenesis of BRCA1 mutation with non-classic malignancies and the response of Poly adenosine diphosphate ribose polymerase inhibitors (PARP) inhibitors in such a scenario. We report an unusual manifestation of the BRCA1 gene with second primary oesophageal squamous cell cancer occurring five years later to triple-negative breast cancer.
