Which of the following diseases occurs due to uncontrolled growth of tissues in the body?

Correct option is C

The correct answer is (c) Cancer

Explanation:

• Cancer is a disease caused by the uncontrolled growth and division of abnormal cells in any part of the body.

• In a healthy body, cells grow and divide to form new cells as the body needs them; in cancer, this process breaks down.

• These extra cells can form masses of tissue called tumors, which can be benign (not cancerous) or malignant (cancerous).

• Malignant tumors can spread to, or invade, nearby tissues and travel to other parts of the body through the blood and lymph systems (metastasis).

• Major causes include genetic mutations, tobacco use, radiation, and certain infections.

Information Booster:

• Biopsy is the common diagnostic test used to confirm the presence of cancerous tissues.

• Chemotherapy and Radiotherapy are standard treatments used to destroy cancer cells.
