C75: Malignant neoplasm of other endocrine glands and related structures

The group of conditions referred to as malignant neoplasms of other endocrine glands and related structures involves cancerous growths in the endocrine system, which is a network of glands that produce and distribute hormones. Commonly affected parts could include the pineal, pituitary, or thymus gland. These conditions are typically caused by abnormal and uncontrolled cell growth, leading to the formation of a neoplasm, which can be cancerous (malignant). It's not a contagious group of conditions; they can't be passed from person to person. Symptoms vary depending on which gland is affected, but can include fatigue, unexplained weight loss or gain, irritability and mood changes, and skin changes. Disease progression depends on the type and stage of the neoplasm, which would usually grow and potentially spread to other parts of the body over time, often interfering with the normal function of the affected glands.
