Anaplasia refers to undifferentiated cell growth in a malignant neoplasm (tumor). Lack of differentiation is considered a hallmark of malignancy. The term anaplasia literally means "to form backward." It implies dedifferentiation, or loss of structural and functional differentiation of normal cells. It is now known, however, that at least some cancers arise from stem cells in tissues; in these tumors failure of differentiation, rather than dedifferentiation of specialized cells, account for undifferentiated tumors.

What is meant by the term anaplastic?
There is no information for the term anaplastic, however, anaplasia refers to a method of reversing the differentiation in cells that have the characteristics of malignant tumor. The term originates from the Greek word "plasis" meaning formation.
What is ananplasia?
Most medical dictionaries say that anaplasia loss of the cellular microscopic features which distinguish one type from another. Anaplastic cells become smaller and simpler in structure and no longer combine to form recognizable tissues. It is a common feature of cancer and, in general, the greater the anaplasia the more malignant and dangerous the tumor. It means that the tissues have lost their distinctive features and have reverted back to more primitive shapes.
What is a change in cell structure and orientation?
A change in cell structure and orientation refers to a modification in the shape, size, or arrangement of cells within a tissue or organism. This can be caused by various factors, such as growth, development, injury, or disease, leading to altered cell function and physiological consequences. Tracking these changes helps researchers understand cellular behaviors and tissue responses in different conditions.
What cell have specific job in a cell?
The body
What is the medical term meaning tumor of the flesh?
A sarcoma (from the Greek 'sarx' meaning "flesh") is a general term describing a MalignantNeoplasm, or Cancer, that arises from transformed Connective_tissueCell_(biology).
What is the medical term used for a change in form or structure?
Trophy, trophies is growth
What is a tumor in which the cells begin dividing at an uncontrolled rate and become invasive?
The tumor you're describing is called a malignant tumor, or cancer. Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body, a process known as metastasis. Treatment typically involves surgery, chemotherapy, radiation therapy, or a combination of these methods.
What is the difference from a hard tumor or a soft tumor?
A hard tumor is not a tumor
What does the medical terminology combining form ana- mean?
Ana- means without, so anaplasia means without development.
What is anaplasia?
Anaplasia refers to the loss of normal cellular features and organization in a tissue or cell, leading to a lack of differentiation. It is commonly seen in cancer cells and is a hallmark of malignancy, as these cells exhibit increased proliferation and decreased specialization compared to normal cells. Anaplastic cells often have altered nuclear morphology and exhibit high variability in size and shape.
Is Wilms' tumor malignant?
Wilms' tumor is a type of malignant tumor
What is the medical term meaning without formation loss of differentiation?
Anaplasia means loss of differentiation of cells.
