C00-C75: Malignant neoplasms, stated or presumed to be primary, of specified sites, except of lymphoid, haematopoietic and related tissue

Malignant neoplasms, stated or presumed to be primary, of specified sites, except of lymphoid, haematopoietic and related tissue, are a group of cancerous growths that begin in various parts of the body, excluding the lymph system, bone marrow, and similar tissues. These growths, or tumours, start from one spot but can potentially spread to other areas. They tend to grow fast and can interfere with the body's normal functions, causing symptoms common to many cancers, such as fatigue, unexplained weight loss, and changes to skin health. Malignant neoplasms can range widely, affecting major systems like the nervous system, digestive tract, kidneys, and more. Factors such as genetics, exposure to certain chemicals, and lifestyle habits like smoking or unhealthy diet may contribute to their formation. Understanding the nature and progression of these conditions can be key for timely medical intervention and appropriate care.
