Photocarcinogenesis – DNA Damage and Gene Mutationsons in which epidermal cells die in apoptosis (“sunburn cells”) and strong inflammation occurs (vasodilation, extravasation, and infiltrates of leukocytes), turning the skin red (erythema) and swollen (edema). In excessive cases the skin ends up peeling, or it may even develop blisters. Fair-skinnedDAMP 发表于 2025-3-25 12:06:29

Oncogenic Virusesy highly complex extracellular and intracellular control of cell cycle and apoptosis. It is a hallmark of malignant cells to grow in the absence of appropriate extracellular signals such as growth factors or cytokines, which are either not sensed or not required as a consequence of disturbed intraceGEST 发表于 2025-3-26 00:56:06

Molecular Events in Skin Cancerelial tumors, such as keratinocyte-derived basal cell carcinomas (BCC) and squamous cell carcinomas (SCC), and neuroendocrine Merkel cell carcinoma (MCC), skin malignancies also include neuroectodermal malignant melanoma (MM), as well as tumors of skin-associated tissues, lipomas, angiosarcomas, tumINERT 发表于 2025-3-26 16:19:03
Etiological Factors in Cutaneous Carcinogenesis – An Introduction consist of a complex interplay between environmental and host-related factors. Well-known environmental risk factors are exposure to sunlight , ionizing radiation , and various chemical carcinogens. Infections with certain viruses are also likely to be involved in skin cancer carcinogenesis.projectile 发表于 2025-3-26 16:55:17
