Which among the following is a cancer of the immune system?

Appeared in: AIIMS Raipur lecturer 2021

Explanation

Lymphoma is a cancer that originates in the lymphatic system, a vital part of the body's immune system.
It specifically involves the uncontrolled growth of lymphocytes, a type of white blood cell responsible for fighting infections.
These abnormal lymphocytes can build up in lymph nodes, the spleen, bone marrow, and other parts of the body, forming tumors.

Option A: Carcinoma is a cancer that arises from epithelial cells, which line the skin and internal organs.
Option B: A hernia is not a cancer. It is a physical condition where an organ protrudes through a weak area in the muscle or tissue that holds it in place.
Option D: Sarcoma is a cancer of connective tissues, such as bone, muscle, fat, and cartilage.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of cancer based on tissue of origin as background academic context rather than a clinical decision trigger.
Correctly identifying the type of cancer is the first and most critical step in oncology nursing, as it determines the entire treatment plan, from surgery and radiation for localized solid tumors to systemic chemotherapy or immunotherapy for hematological malignancies like lymphoma.
Nurses play a key role in educating patients about their specific cancer type, helping them understand why their treatment is different from that of a patient with another type of cancer.
What if? If a patient's cancer originated from blood-forming cells in the bone marrow, it would be classified as Leukemia. While also a 'blood cancer' like lymphoma, its presentation and treatment (e.g., bone marrow transplant) can differ significantly.

How to Approach the Question

First, identify the core concepts in the question stem: 'cancer' and 'immune system'.
Next, analyze the options provided. The prefix 'Lymph-' in 'Lymphoma' is a strong clue that it is related to the lymphatic system, which is the primary network of the immune system.
Evaluate the other options. Recall or deduce that Carcinoma and Sarcoma are major cancer types but are defined by different tissues of origin (epithelial and connective, respectively).
Eliminate 'Hernia' immediately, as it is a well-known medical condition but not a form of cancer (malignant neoplasm).
By matching the keyword 'immune system' with the term 'Lymphoma', you can confidently select the correct answer.
