The integrative nature of cancer, characterised by the coexistence of malignant and normal cells, diminishes the efficacy of single-modality therapies for both early-stage and late-stage tumours. Consequently, multimodal interventions, including surgery, radiation, chemotherapy, and immunotherapy, are necessary. Patient heterogeneity and cancer resistance complicate treatment outcomes, requiring personalised therapeutic approaches. Cancer cells operate as astute entities, collaborating with the human body to circumvent treatment, thus necessitating correspondingly intricate therapeutic approaches. Existing medicines are insufficient, rendering cancer a continual struggle for medical professionals and researchers. The progression of nanotechnology has led to the emergence of theranostics, which combines diagnosis and therapy into a unified approach. Nanotheranostic drugs, influenced by external stimuli such as light, magnetic fields, and ultrasound, signify a novel advancement in anti-cancer treatments. Although numerous stimuli-responsive theranostic nanomaterials have demonstrated proof-of-concept, none have progressed to clinical trials. This chapter examines diverse theranostic nanomaterials, emphasising inorganic agents utilised without chemical alterations. It evaluates the efficacy of theranostic agents licensed for preclinical and clinical trials. Chemotheranostics, radiotheranostics, immunotheranostics, and phototheranostics present considerable potential owing to their extensive surface area, customisable attributes, and biocompatibility. Notwithstanding significant progress, difficulties, including particle size, charge, medication stability, and surface changes, remain. Interdisciplinary collaboration among biological, pharmaceutical, materials science, and nanotechnology sectors is crucial for enhancing clinical translation.

Researchers have developed advanced in vitro systems using uterine organoids and decellularized tissue scaffolds to understand and model these diseases. The main limitations of traditional 2D monolayer cultures include reduced biological activity, reduced hormone responsiveness, and lack of interaction with ECM. Researchers have investigated 3D culture approaches to address these shortcomings, such as scaffold-free organoids and decellularized tissue scaffolds. Organoid systems can better recapitulate the cellular heterogeneity and physiological functions of the native endometrium. Decellularization protocols have been optimized to generate intact uterine scaffolds that preserve the structural and compositional features of the ECM. Implantation of these bioscaffolds into animal models demonstrated their biocompatibility and regenerative potential. Further refinements of organoid and scaffold technologies, including chemically defined matrices and organ-on-a-chip platforms, will improve our ability to model the uterus.
