Question

Benign tumor is one which is
(A)Showing metastasis
(B)Differentiated and capsulated
(C)Undifferentiated and non capsulated
(D)Differentiated and non capsulated

Answer 1

Hint: Benign tumor is one which is formed by the process by which cells become progressively more specialized and are covered by the special type of connective tissue derived from the structure surrounding the tumor.

Complete answer:
 Benign tumor is one which is Differentiated and capsulated. Benign tumors generally have a slower rate of growth than malignant tumors and therefore the tumor cells are usually more differentiated (cells have more normal features). they're typically surrounded by an outer surface (fibrous sheath of connective tissue) called a capsule or stay contained within the epithelium.

Additional Information: A benign tumor is defined as a mass of cells (tumor) that lacks the ability to either invade neighboring tissue or metastasize (spread throughout the body). When these are removed, benign tumors usually don't grow back, whereas malignant tumors sometimes do. Unlike most benign tumors elsewhere within the body, benign brain tumors are often life-threatening.
Although it was seen that the most benign tumors aren't life-threatening, some types of benign tumors have the potential to become cancerous (malignant) through a process referred to as tumor progression. Because of this reason and other possible negative health effects, some benign tumors are removed by surgery. Benign tumors are very diverse; they'll be asymptomatic or may cause specific symptoms, counting on their anatomic location and tissue type. They grow outward, producing large, rounded masses which may cause what's referred to as a "mass effect".
So, the correct answer is ‘Differentiated and capsulated’.

Note: Other than Benign tumors, the Malignant tumors are also there. These are cancerous. They develop when cells grow uncontrollably. If the cells still grow and spread, the disease can become life-threatening. Malignant tumors can grow quickly and spread to other parts of the body during a process called metastasis
