What is the difference between stage 1 and stage 2 cancer?
Most kinds of cancer do not use this stage. Stage I. Cancer is only in the cells where it first started and the area is small. This is considered early stage and most curable. Stage II. Cancer is in the organ where it first started. It may be a bit larger than stage I and/or may have spread to nearby lymph nodes.

What happens after cancer diagnosis?
After cancer is diagnosed, healthcare providers will begin to determine the grade and stage of the cancer. This helps them to plan the best treatment and look at overall outcomes and goals.
What does the grade of cancer mean?
What does the grade of a cancer mean? The grade of a cancer describes what the cancer cells look like using a microscope. Most cancers are graded by how they compare with normal cells. Low grade or grade I tumors are well-differentiated. This means that the tumor cells are organized and look more like normal tissue.
How are cancers graded?
Most cancers are graded by how they compare with normal cells. Low grade or grade I tumors are well-differentiated. This means that the tumor cells are organized and look more like normal tissue. High grade or grade III tumor cells are poorly differentiated. This means that the tumor cells don't look like normal cells.
What is a grade II tumor?
They're disorganized under the microscope and tend to grow and spread faster than grade I tumors. Cancer cells that don't look well-differentiated or poorly differentiated are called moderately differentiated, or grade II. In general, cancer cells are graded using the scale below.
Is carcinoma in situ pre-malignant?
Carcinoma in situ is considered pre-malignant or pre-cancer. Abnormal cells are found only in the first layer of cells in the place where the changes first started. The cells do not invade the deeper tissues. These cells may become cancer over time, so it's good to find and treat them before that happens.
What is cancer staging?
Cancer staging can be clinical or pathological: 1 Clinical Staging: Based on test results received before surgery, such as physical exams, lab tests, and imaging scans 2 Pathological Staging: Based on what the doctor finds during surgery and provides the most accurate information about a patient’s prognosis
Why is staging important?
According to the National Cancer Institute, staging is an important tool that provides doctors with information about where the cancer is located, how large the tumor is, and whether it has spread to other parts of the body.
How many stages of cancer are there?
After conducting an array of tests, doctors often assign cancer to one of five stages: Stage 0, Stage 1, Stage 2 , Stage 3 , or Stage 4. Sometimes, these stages can be further divided using letters, such as Stage 2A or Stage 3B.
What does the letter T mean in cancer?
The National Cancer Institute explains how each letter of the system helps health care providers evaluate the extent of cancer in the body: T: Refers to the size and location of the primary tumor. N: Refers to the number of nearby lymph nodes that have cancer.
What is clinical staging?
Clinical staging is based on the results of tests done before surgery, such as physical examinations and imaging scans. Pathological staging is based on what is found during surgery. Clinical stage is often indicated with a lowercase “c” before the TNM classification.
How to tell if a cancer is staged?
Staging helps describe where a cancer is located, if or where it has spread, and whether it is affecting other parts of the body. Doctors often use diagnostic tests to determine a cancer’s stage. Staging may not be complete until all of these tests are finished. Knowing the stage helps the doctor: 1 Plan treatment, including the type of surgery and/or whether chemotherapy or radiation therapy are needed 2 Predict the chance that the cancer will come back after the original treatment 3 Predict the chance of recovery 4 Talk about the diagnosis in a clear, common language with the entire health care team 5 Determine how well the treatment worked 6 Compare how well new treatments work among large groups of people with the same diagnosis

The letter "M" indicates whether the cancer has spread to other parts of the body, called distant metastasis. If the cancer has not spread, it is labeled M0. If the cancer has spread, it is considered M1.
How many stages of cancer are there?
Doctors combine the T, N, M results and other factors specific to the cancer to determine the stage of cancer for each person. Most types of cancer have four stages: stages I (1) to IV (4). Some cancers also have a stage 0 (zero).
What is the difference between stage 0 and stage 1 cancer?
Stage 0 cancers are still located in the place they started and have not spread to nearby tissues. This stage of cancer is often highly curable, usually by removing the entire tumor with surgery. Stage I. This stage is usually a small cancer or tumor that has not grown deeply into nearby tissues.
