Tissue abnormalities refer to changes in the structure or function of tissues in the body, which can indicate underlying health issues. These changes can be caused by various factors, including infections, inflammation, or genetic disorders. Common examples include tumors, which are abnormal growths of tissue, and fibrosis, where tissue becomes thick and stiff due to excessive scar formation. Identifying tissue abnormalities often involves medical imaging techniques, such as MRI or CT scans, and laboratory tests, including biopsies. Early detection is crucial, as some abnormalities may lead to serious conditions, including cancer or organ dysfunction, making timely diagnosis and treatment essential for better health outcomes.
