tumorszövetek

Tumorszövetek, also known as tumor tissue, refers to abnormal growths of cells that form a mass or lump. These tissues arise from uncontrolled cell division, a process that deviates from the normal regulation of cell proliferation and death. Tumors can be benign or malignant. Benign tumors are non-cancerous and do not invade surrounding tissues or spread to other parts of the body. They often remain localized and can sometimes be surgically removed. Malignant tumors, on the other hand, are cancerous. They have the ability to invade nearby healthy tissues and can metastasize, meaning they can spread to distant parts of the body through the bloodstream or lymphatic system, forming secondary tumors. The development of tumorszövetek is a complex process involving genetic mutations and alterations in cellular signaling pathways. These changes disrupt the normal cell cycle, leading to the accumulation of abnormal cells. The characteristics of tumorszövetek, such as their growth rate, appearance under a microscope, and invasiveness, are crucial for diagnosis and determining the appropriate treatment. Medical professionals analyze tumorszövetek through biopsies to identify the type of tumor, its grade (how abnormal the cells look), and its stage (how far it has spread), which are all essential factors in planning patient care.
