Melanoma Diagnosis and Staging Concepts

The video tutorial explains the process of diagnosing melanoma, a type of skin cancer, typically done by dermatologists. It covers various biopsy methods, including punch and excisional biopsies, and details the components of a pathology report. The tutorial also discusses lymph node biopsies and imaging tests like MRI, CT, PET, and ultrasound scans. Finally, it explains the TNM system for cancer staging, detailing the characteristics of each melanoma stage from zero to four.
