What is Staging? Definition: Staging is a process in which doctors evaluate cancer to see the size of a tumor and also to determine where the cancer is in the body. What the stages are: There are several systems of staging when it comes to cancer and classifying tumors. Impact on treatment: Staging of cancer is a useful way for doctors to determine what the best and most appropriate form of treatment is for a particular patient since this may be different for cancer at stage 1 versus stage 4.

What is Grading? Definition: Grading is a system that is used to describe the level of abnormality of cancerous tumor cells. What the grades are: The grades are X and levels 1 to 4. How grading is done: The grade of each particular type of cancer is determined by taking tissue during a biopsy and examining it under a microscope. Impact on treatment: It is important for an oncologist to know what grade a particular cancer is in as this allows for them to plan for the correct treatment option.

Difference between Staging and Grading Definition Staging is the system of classification used in which a doctor evaluates the size of a cancerous tumor and degree of spread of cancer in the body. Names of the categories Staging uses the TNM system in which T represents tumors, N represents lymph nodes, and M represents metastasis. What the categories mean In staging: T0 indicates that no tumor has been found, Tis is a tumor in situ, and T1 to T4 are increasing sizes of the tumor.

Microscopic features Staging is not concerned with the microscopic appearance of cells while grading is concerned with the microscopic appearance of cells.

Tumors Staging is concerned with the tumors while grading is concerned with the cells. Grading Staging and grading are both classification schemes that doctors can use to evaluate the level of severity of cancer. This allows the surgeon to see what lymph nodes are draining from the tumor first and identify a sentinel lymph node.

Then, the surgeon makes a small incision in the skin and identifies the lymph node for removal. A pathologist studies the lymph node to determine if it contains cancer. This technique uses a smaller incision and can prevent patients from needing a more invasive surgery.

It can shorten postoperative recovery times and lower the risk of side effects like lymphedema , swelling caused by the removal of more lymph nodes. Some patients have concerns about the radiotracer used to find the sentinel lymph node. While it is radioactive, the tracer has a very low-energy emission particle. No severe adverse reactions have been reported, and the only negative reaction reported has been rare episodes of brief pain during the injection. Tell me about advances in using sentinel lymph node biopsies to help more cancer patients.

Sentinel lymph node biopsy has been very well established for melanoma and breast cancer treatment. I completed a Phase III clinical trial that led to the Food and Drug Administration approval of a new radiotracer for use in patients with oral cavity cancer. Now, I am leading an effort to start a Phase III clinical trial comparing sentinel lymph node biopsy to a more traditional technique called an elective neck dissection for early-stage oral cavity cancer patients.

In addition, Michael Frumovitz, M. These advances help us learn more about the cancer itself, while lessening side effects for patients. Sentinel lymph node biopsy is personalized surgery. The surgery is tailored to the individual patient to target the lymph nodes most likely to harbor cancer. It helps patients get back to their everyday lives more quickly.

Cancer Grade vs. Locally advanced breast cancer means the cancer has spread into the surrounding area, such as the lymph nodes, the skin or chest muscle. But it has not spread to other parts of the body. Secondary breast cancer is also called metastatic breast cancer, advanced breast cancer, or stage 4 breast cancer. It means that the cancer has spread to other parts of the body, such as the liver or bones.

The grade describes how a cancer cell looks under the microscope and whether they are similar or very different to normal cells. You might hear your doctor use the terms well differentiated, moderately differentiated, or poorly differentiated. A pathologist checks the cancer cells for features that can help predict how likely the cancer is to grow and spread.

These include:. Low grade grade 1 the cells look similar to normal breast cells and are slow growing. These are well differentiated cancers. They are arranged in small tubules for ductal cancer and cords for lobular cancer. These cancers tend to grow and spread slowly and have a good outlook prognosis. Intermediate grade grade 2 the cells look quite different to normal breast cells. They are moderately differentiated. About the Author: Morag.
