B21: Human immunodeficiency virus [HIV] disease resulting in malignant neoplasms

B21.7: HIV disease resulting in multiple malignant neoplasms

HIV disease resulting in multiple malignant neoplasms is a serious health condition where the human immunodeficiency virus (HIV) triggers the development of several types of cancer. This occurs because HIV weakens the immune system's ability to keep the body healthy, facilitating the growth of harmful cells. In this condition, multiple malignant neoplasms, or cancerous tumors, develop in different parts of the body. Symptoms often vary depending on the location and size of the tumors, but could include unusual lumps, unexplained weight loss, fatigue, and persistent pain. Over time, if untreated, the condition can progress with the spread of cancer cells to other parts of the body, affecting multiple organ systems and leading to a more severe illness.
