Why Does Cancer Occur
Cancer arises when certain cells in the body grow uncontrollably and invade other tissues. This can happen almost anywhere since our bodies are composed of trillions of cells. Typically, cells grow, divide, and replace old or damaged cells in an orderly manner. However, when this process malfunctions, abnormal cells multiply and may form tumours. Tumours can be benign (non-cancerous) or malignant (cancerous). Malignant tumours invade nearby tissues and spread to other parts of the body (metastasis), while benign tumours do not spread and often remain harmless. However, large benign tumours can sometimes cause serious issues, especially in sensitive areas like the brain.
