How are all cancers the same?

All cancers share the fundamental characteristic of uncontrolled cell growth, where normal regulatory mechanisms fail, leading to the formation of tumors. They arise from genetic mutations that disrupt cellular processes, allowing abnormal cells to proliferate and evade apoptosis. Additionally, cancers often exhibit the ability to invade surrounding tissues and metastasize to distant sites in the body. Despite their common traits, cancers can vary significantly in their behavior, treatment responses, and outcomes.
