Vedclass · Answer

(B) Tumors are classified into two types: $Benign$ and $Malignant$.$Benign$ tumors normally remain confined to their original location and do not spread to other parts of the body,causing little damage.$Malignant$ tumors are cancerous. They are a mass of proliferating cells called neoplastic or tumor cells. These cells grow very rapidly,invading and damaging the surrounding normal tissues.As these cells actively divide and grow,they also starve normal cells by competing for vital nutrients. Cells sloughed from such tumors reach distant sites through the blood,and wherever they get lodged in the body,they start a new tumor there. This property called $Metastasis$ is the most feared property of malignant tumors.$Lipoma$ is a benign tumor made of fat tissue.Therefore,only $Malignant$ tumors are considered cancerous.
