\nIn normal cells, growth and differentiation are tightly controlled by genetic programs and regulatory mechanisms. Cancer cells are characterized by a breakdown of these control mechanisms. This leads to uncontrolled cell proliferation, loss of differentiation, and the potential to invade surrounding tissues and spread to distant sites, forming malignant tumors. Benign tumors are localized growths that do not invade or spread, also resulting from deregulation but less severe.
\n<\/section>\n
\nThe fundamental characteristic of cancer cells is the loss of control over cell growth and division, contrasting sharply with the tightly regulated processes in normal cells.
\n<\/section>\n
\nCancer development involves genetic mutations and epigenetic changes that disrupt cell cycle control, apoptosis (programmed cell death), and cell-cell communication.
