Carcinogenesis - PowerPoint PPT Presentation


Carcinogenesis

The multistep process of carcinogenesis at both phenotypic and genetic levels, including excessive growth, local invasion, and metastasis. Explore the six changes in normal cell physiology that result in cancer formation and the mechanisms of action of oncoproteins. Discover the role of important ge

Radiation Hazards and Safety in Medical Practices

Understanding the effects of radiation exposure on different body parts, from early effects on highly mitotic cells to late effects like carcinogenesis and cataractogenesis. Emphasizing the importance of minimizing exposure through the ALARA concept and protective measures for patients, fellow worke

Understanding the Fundamentals of Carcinogenesis and Cancer Hallmarks

Carcinogenesis involves non-lethal genetic damage, clonal expansion of precursor cells, and multi-step processes, with the involvement of normal regulatory genes. The hallmarks of cancer include self-sufficiency in growth signals, insensitivity to inhibitory signals, evasion of cell death, replicati
