D00-D09: In situ neoplasms
In situ neoplasms belong to a group of conditions characterized by the presence of abnormal cell growth confined to the original location or site of the cells within the body. Unlike malignant (cancerous) neoplasms, these growths haven't spread or invaded other tissues, which is a process known as metastasis. The growths can arise in any part of the body but are often found in the skin, breast, lung, and digestive tract. Common symptoms can depend on the location of the growth and can include lumps, changes in skin color or texture, changes in bowel movements, or persistent cough. The development of in situ neoplasms often involves genetic and environmental factors, including smoking and exposure to certain chemicals or radiation. The condition's progression may vary, with some growths remaining stable or disappearing over time, while others may eventually develop into cancer if left untreated.
