Malignant Cells

Malignant cells are abnormal cells that continue to grow and divide uncontrollably, forming a mass called a tumor. Unlike normal cells, they can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system. This invasive behavior can interfere with the normal function of organs and tissues, making malignant cells characteristic of cancer. Their rapid, uncontrolled growth and ability to spread distinguish them from benign (non-cancerous) cells, posing significant health risks and requiring medical intervention.
