Cellular abnormalities refer to changes in the structure or function of cells that can lead to various health issues. These changes can occur due to genetic mutations, environmental factors, or infections. Abnormal cells may grow uncontrollably, leading to conditions such as cancer or tumors, which can disrupt normal bodily functions. Detecting cellular abnormalities often involves laboratory tests, such as biopsies or blood tests, which help identify unusual cell growth or characteristics. Early detection is crucial for effective treatment and management of diseases associated with these abnormalities, improving patient outcomes and quality of life.
