Quiz 5: Coding Infectious Diseases

Medicine

Cancer is the unconstrained growth and proliferation of cells that compete with the healthy cells for nutrition, space and eventually cause the death of normal cells. Cancer can be of different types depending upon the type of cells, organ affected and stage. The spreading of cancer to other places in the body is called metastasis. The difference between benign and malignant are as follows: img Malignant cancer becomes dangerous due to metastasis whereas, benign cancer does not undergo metastasis and thus are easy to remove.

Cancer can be defined as the uncontrolled growth and proliferation of cells that compete with the normal cells for nutrition, space and eventually cause the death of healthy cells. Cancer can be of different types depending upon the type of cells, organ affected and stage of development. The spreading of cancer to other places in the body is called metastasis. Cancer is the uncontrolled growth of cells that invade healthy cells for space and nutrition. Hence, this particular statement is incorrect. Hence, the option (b) is not the correct answer. Malignancy is the spread of the cancerous cells to distant tissues leading to the development of the life-threatening condition. Hence, the option (c) is not the correct answer. Metastasis is the term used when the cancerous cell mass has spread to the adjacent or even far off tissues and is rapidly proliferating to destroy a large number of healthy cells. Thus, the option (d) is also incorrect. Neoplasm is the term used to specify the presence of uncontrolled growth and proliferation of cells that are potent to become cancerous. This mass of cells is called a tumor. Hence, the correct answer is Option (a).

Cancer is the unconstrained growth and proliferation of cells that compete with the healthy cells for nutrition, space and eventually cause the death of normal cells. Cancer can be of different types depending upon the type of cells, organ affected and stage. The spreading of cancer to other places in the body is called metastasis. Neoplasm is referred to as an abnormal growth or cells of a tissue that form a tumor. The neoplasms can be benign or malignant. The neoplasm is categorized into four groups which are as follows: (i) Adenoma: Adenoma is the growth of cells in an organ or glands. These glands have cells of epithelial origin. They are usually benign but have the potential to become malignant adenocarcinoma. (ii) Melanoma: Melanoma is the cancer of the skin which is very dangerous and is malignant. It is the uncontrolled growth of melanocytes. (iii) Leukemia: Leukemia is the cancer of the white blood cells. These cells are immature and cause loss of immunity in the individual. (iv) Papilloma: Papilloma is an outgrowth on the surface of the skin that forms warts. However, it is the benign outgrowth and can be removed through surgery. Malignant cancer becomes dangerous due to metastasis whereas, benign cancer does not undergo metastasis and thus are easy to remove.
