The document discusses the stages of mitosis: interphase, prophase, metaphase, anaphase, and telophase. It explains what occurs in each stage, such as DNA replication in S phase of interphase and chromosomes separating in anaphase. The document also briefly mentions cancer occurs due to uncontrolled cell growth caused by viruses, chemicals, or mutations.
