Grading is based on the measuring of the tumor's cell appearance and the extent of it progress in the patient's body. The scale used is 1 to 4 (low grade 1, to high grade 4) the higher the grade or scale number the more aggressive the tumor.
The scale of malignancy is based on the tumor/cancer's pathology, and the variation in its cells to that of normal body cells. Medical labs look at the size or area of the tumor/cancer and its growth rate (mitotic index). They take into consideration the type of tumor/cancer and its location. They look at margin surrounding the tumor/cancer, to determine if it contains any cells that have strayed beyond the surgical site. They look for other cell abnormalities, which can indicate a change in cell structure which often indicates that they can become malignant and therefore may required chemotherapy or radiation therapy. They use this information and more, before they determine the degree of malignancy and thereby assigning a stage or grade to it. This is all done to determine the type of treatment which will be needed, if treatment is possible.

I hope this information helps you. And I hope you are asking out of curiosity rather that personal need.
What else can I help you with?
What is the worst malignant or benign cancer?
If you mean, "What is the worst : malignant or benign cancer?" the answer is Malignant. If a person has a tumor for instance, in the benign state it is virtually harmless, it means that the tumor would not be cancerous, but, when a tumor is malignant that means cancer has developed and is spreading to other parts/cells in the body.Hope that helps!
What does malignant neoplasm progression mean?
Malignant (very virulent or infectious) Neoplasm (abnormal gorwth of cells). It is sometimes defined as cancer. Technically, Malignant Neoplastic Progession is the abnormal and uncontrolled growth of cells or tissue which eventually forms a tumor.
What does osteosarcoma mean?
A malignant tumor of bone in which there is a proliferation of osteoblasts.
The mass of cells that result from uncontrolled cell growth?
The mass of cells that result from uncontrolled cell growth is called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.
What does Tumor mean?
A disease in which malignant (cancer) cells are found in the kidney, and may spread to the lungs, liver, or nearby lymph nodes. Wilms tumor usually occurs in children younger than 5 years old.
What does Wilms tumor mean?
A disease in which malignant (cancer) cells are found in the kidney, and may spread to the lungs, liver, or nearby lymph nodes. Wilms tumor usually occurs in children younger than 5 years old.
What does Staging a tumor mean?
Staging a tumor is assessing the extent of tumor spread. It's described in numbers, usually 1 through 4. For example, you might have heard someone say that a person has stage 4 cancer, which is when the cancer has metastasized and spread to other organs or throughout the body. When a malignancy is diagnosed, tests are performed to assess whether it has metastasized (spread to other locations) and also to see how differentiated the tumor cells are (this is referred to as grading the tumor). So staging = assessing tumor spread and grading = assessing degree of differentiation.
What does negative malignant cells mean?
A malignant cell is a cancer cell. Once that is growing out of control. No malignant cell means the absence of cancer cells. This means the observed cells are healthy.
What does it mean SC tumor?
"SC tumor" could refer to a subcutaneous tumor, which is a tumor that develops just beneath the skin. These tumors can be benign or malignant and may require further evaluation and treatment by a medical professional.
What does benign malignant mean?
The word benign means good while malignant means badly born. A benign tumor is not very serious and made be removed if it is in the wrong place but otherwise it causes no harm. A malignant tumor must be removed as it may spread and cause great harm.
What does sarcoma mean?
It's derived from the Greek word 'sarx' - meaning 'flesh'. The word sarcoma can be applied to any malignant tumor.
What is a Gilioma?
It appears there may have been a spelling error. Did you mean "glioma"? If so, a glioma is a type of tumor that originates in the brain or spinal cord and arises from the supportive tissue of the brain. Gliomas can be benign or malignant, and treatment usually involves a combination of surgery, radiation therapy, and chemotherapy.
