1056a

1056a is a designation used in the context of the International Classification of Diseases (ICD-10), which is a medical classification list by the World Health Organization (WHO). The "a" in 1056a indicates that it is a subcategory of the broader category 1056, which is titled "Malignant neoplasm of skin".

The specific designation 1056a refers to "Malignant melanoma of skin, unspecified". This means that the cancerous tumor is a type of melanoma, which is a form of skin cancer that develops from the pigment-producing cells known as melanocytes. The term "unspecified" indicates that the exact location or subtype of the melanoma is not detailed in the diagnosis.

Melanoma is considered a serious type of skin cancer due to its potential for rapid growth and metastasis, meaning it can spread to other parts of the body. Early detection and treatment are crucial for improving outcomes. The ICD-10 code 1056a is used for diagnostic and statistical purposes, helping healthcare providers and researchers to categorize and study cases of this specific type of cancer.
