Question

Sarcoma is cancer of
A) Epithelial tissue
B) Blood
C) Mesodermal tissue
D) Endodermal tissue

Answer 1

Hint: Cancer refers to any of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal human tissues. Cancer usually has the ability to spread throughout the body. Cancer is the second leading cause of death in the world.

Complete answer:
Sarcomas are cancers caused by transformed cells derived from mesenchymal (connective tissue or mesoderm tissue). Therefore, malignant tumors codified of cancellous bone, cartilage, fat, muscle, blood vessels, or hematopoietic tissue are considered sarcomas. Sarcomas are the opposite of malignant tumors that originate from epithelial cells called carcinoma.

Types of sarcoma:
Adult fibrosarcoma: usually affects healthy tissues in the legs, arms, or trunk. This is usually a basic habit of individuals between the ages of 20 and 60, but it can also occur in individuals of all ages, even babies.
Alveolar soft part sarcoma: is a rare cancer that mainly affects young people. These tumors are most common in the legs.
Clear cell sarcoma: is a rare cancer that usually starts in the tendons of the arms or legs. Under the microscope, it has certain characteristics of malignant melanoma, which starts from skin cells that produce pigment. It is not yet known how cancers with these characteristics start in areas other than the skin.

Thus, the option (c) is the correct answer.

Note:Sarcomas are rare in adults, accounting for about 1% of all adult cancer diagnoses. They are relatively common in children. Between 1,500 and 1,700 children in the United States are identified with bone or soft tissue sarcoma each year.
