An autoimmune disease occurs when the body’s immune system erroneously identifies its own healthy tissues as foreign invaders and mounts an inflammatory attack against … Read more
1. Defining Local Tumor Invasion Local tumor invasion marks a critical and dangerous inflection point in the progression of neoplastic disease. It is the biological process by which malignant cells break free from their primary anatomical boundary and actively penetrate adjacent, healthy host tissues. Unlike benign tumors, which grow by expansion and displace surrounding structures … Read more
