- Cancer definition: A group of diseases involving uncontrolled cell division
- Cell cycle connection: Cancer occurs when cell cycle checkpoints fail
- Genetic basis: Caused by mutations in genes that control cell division
- Tumor types: Benign (non-spreading) vs malignant (spreading)
- Metastasis: The spread of cancer cells to distant body parts
- Risk factors: Include carcinogens, lifestyle factors, and genetic predisposition
- Treatment approaches: Surgery, chemotherapy, radiotherapy, and targeted therapies
