PATHOLOGY

Detailed explanation-1: -When cells grow old or become damaged, they die, and new cells take their place. Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue. Tumors can be cancerous or not cancerous (benign).

Detailed explanation-2: -An abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Tumors may be benign (not cancer) or malignant (cancer). Benign tumors may grow large but do not spread into, or invade, nearby tissues or other parts of the body.

Detailed explanation-3: -A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).

Detailed explanation-4: -Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong.

Detailed explanation-5: -Cancer cells or tumors in organs or the bloodstream can disrupt organ function. They may destroy healthy cells in organs, block their nutrient or oxygen supply, and allow waste products to build up.
