Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A benign tumor differs from a malignant tumor in that a benign tumor
A
is cancerous
B
spreads from the original site
C
does not metastasize and spread
D
typically causes health problems
Explanation: 

Detailed explanation-1: -A benign tumor is an abnormal but noncancerous collection of cells. It can form anywhere on or in your body when cells multiply more than they should or don’t die when they should. A benign tumor is not malignant. It grows more slowly, has even borders and doesn’t spread to other parts of your body.

Detailed explanation-2: -Malignant tumors form when cancerous cells multiply and develop into a mass. Unlike benign tumors, cancer cells may invade nearby tissue. They may also break off from tumors and spread throughout the body, in a process called metastasis.

Detailed explanation-3: -Treatment of Benign Tumors Other benign tumors can spread or become cancerous (metastasize). They can sometimes be treated effectively with medication or your doctor may recommend removing the tumor.

Detailed explanation-4: -A benign tumor is a mass of cells (tumor) that does not invade neighboring tissue or metastasize (spread throughout the body). Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells.

Detailed explanation-5: -The benign tumor is a non cancerous tumor and is normal. Malignant tumor is a cancerous tumor. These cells don’t spread to other tissues or organs and don’t invade other areas of the body. Malignant cells are dangerous and can spread to other organs and tissues.
