PATHOLOGY

Detailed explanation-1: -These cells may form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body. A benign tumor means the tumor can grow but will not spread.

Detailed explanation-2: -Cell changes and cancer Usually, we have just the right number of each type of cell. This is because cells produce signals to control how much and how often the cells divide. If any of these signals are faulty or missing, cells might start to grow and multiply too much and form a lump called a tumour.

Detailed explanation-3: -A tumor is a mass or group of abnormal cells that form in the body. If you have a tumor, it isn’t necessarily cancer. Many tumors are benign (not cancerous). Tumors can form throughout the body.

Detailed explanation-4: -Malignant tumors have cells that grow uncontrollably and spread locally and/or to distant sites. Malignant tumors are cancerous (ie, they invade other sites).

Detailed explanation-5: -Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
