how many stages of cancer
Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing. The American Cancer Society couldn’t do what we do without the support of our partners. The American Joint Committee on Cancer (AJCC) and the Union for International Cancer Control (UICC) maintain the TNM classification system as a way for doctors to stage many different types of cancer based on certain common standards. The clinical stage is often a key part of deciding the best treatment options. Blood Cancer Stages. For reprint requests, please see our Content Usage Policy. Some cancer types may also have fewer category options than other cancer types. For patients who have surgery, another important factor is the extent of the resection — whether or not all of the tumor is removed: The AJCC staging system gives a detailed summary of how far the cancer has spread. The stages of breast cancer range from 0 to IV (0 to 4). Stage0 – means only abnormal cells are present which may become cancer, termed as carcinoma in situ.Some doctors and researchers refer stage 0 as pre cancerous changes with a high potential to develop an invasive cancer in near future. Your doctor will begin to determine this during It has not spread outside of the pancreas. It is determined by examining tissue removed during an operation. Many factors determine the best treatment options for each person. It’s also important to follow recommended screening guidelines, which can help detect certain cancers early. Your pathology report will include information that is used to calculate the stage of the breast cancer — that is, whether it is limited to one area in the breast, or it has spread to healthy tissues inside the breast or to other parts of the body. One way to describe NSCLC is by its clinical or pathologic stage. Together, we’re making a difference – and you can, too. Staging is the process of finding out how much cancer is in a person’s body and where it’s located. Research. They are often written with the Roman numerals I, II, III, and IV. Some cancers also have a stage 0, which is often called carcinoma in situ. Cancer Information, Answers, and Hope. One common system that many people are aware of puts cancer on a scale of 0 to IV. For some cancers, some treatment other than surgery (such as chemo, targeted drug therapy, or radiation) might be done first. The highest stage (stage IV) is any cancer with metastases (M1), no matter the size of the tumor, the lymph node status or other factors. With any type of restaging, the new stage classification is added to the original stage, but it doesn’t replace it. Where is it located? For example, if the 5-year survival rate for a certain stage of a type of cancer is 80%, it means that 80 out of 100 people who have that type and stage of cancer will still be expected to be alive after 5 years. Cervical cancer stage ranges from stages I (1) through IV (4). Along with the type of cancer a person has, the stage of the cancer is one of the most important factors when doctors try to determine a person’s prognosis (outlook). Surgery to try to remove these tumors would be very unlikely to be helpful and could still have major side effects. The stage may be adjusted if you have additional tests or after surgery. From basic information about cancer and its causes to in-depth information on specific cancer types – including risk factors, early detection, diagnosis, and treatment options – you’ll find it here. Your treatment plan is based on the clinical stage. All so you can live longer — and better. The stage of a cancer describes how far the cancer has grown and spread at the time of diagnosis. Small-cell lung cancer (SCLC) has two main stages. One tool that doctors use to describe the stage is the TNM system. In the limited stage, cancer is found in only one lung or nearby lymph nodes on the same side of … The cancer is confined to the pancreas and is larger than 2 cm (0.8 inch) but no more than 4cm (1.6 inches) across (T2) AND it has spread to no more than 3 nearby lymph nodes (N1). © 2021 American Cancer Society, Inc. All rights reserved. Non-small-cell lung cancer (NSCLC) is a more common type of lung cancer than small cell. Grade 1 (G1) means the cancer looks much like normal pancreas tissue. Node (N): Has the tumor spread to the lymph nodes? It’s also important to understand that while the stage of the cancer is important, many other factors can also affect a person’s outlook. In: AJCC Cancer Staging Manual. Cancer treatments and prognoses, or likely outcomes, depend in part on the stage of your disease. Many types of cancer often spread to nearby lymph nodes before they reach other parts of the body. Most types of leukemias aren’t staged the way cancers that form tumors are. Typically, a cancer is staged when it is first diagnosed, before any treatment is given. For example, the 5-year survival rate of a cancer that is initially diagnosed as stage II and later spreads to another part of the body is not necessarily the same as that for a cancer that is initially diagnosed as a stage IV cancer (because it had already spread to another part of the body when first diagnosed). Doctors also check for other nearby tumors. Tumor (T): How large is the primary tumor? Often the reason the cancer can’t be removed is because it has grown into or surrounded nearby major blood vessels. Staging might also be done again at some point if the cancer comes back (recurs) or progresses (grows or spreads without ever having gone away completely). Metastasis (M): Has the cancer metastasized to other parts of the body? Sometimes, cancers with different stages might be treated the same way, or cancers with the same stage might be treated in different ways. Numbers or letters after T, N, and M provide more details about each of these factors. If so, where and how many? But for treatment purposes, doctors use a simpler staging system, which divides cancers into groups based on whether or not they can be removed (resected) with surgery: If the cancer is only in the pancreas (or has spread just beyond it) and the surgeon believes the entire tumor can be removed, it is called resectable. Unresectable (either locally advanced or metastatic). If this happens, only some of the cancer may be removed to confirm the diagnosis (if a biopsy hasn’t been done already), and the rest of the planned operation will be stopped to help avoid the risk of major side effects. National Cancer Institute. Learn more about these partnerships and how you too can join us in our mission to save lives, celebrate lives, and lead the fight for a world without cancer. The cancer is confined to the pancreas and is no bigger than 2 cm (0.8 inch) across (T1). Of course, the stage of a cancer isn’t the only factor used to decide which treatments might be best. For example, T3a or T3b. The cancer is confined to the pancreas and is larger than 2 cm (0.8 inch) but no more than 4cm (1.6 inches) across (T2) AND it has spread to 4 or more nearby lymph nodes (N2). Cancer Staging. Sometimes, though, the cancer has spread further than the clinical stage estimates, and may not predict the patient’s outlook as accurately as a pathologic stage. Metastatic: If the cancer has spread to distant organs, it is called metastatic (Stage IV). 2015. What patients and caregivers need to know about cancer, coronavirus, and COVID-19. The stage of cancer of the esophagus, for example, depends on whether the cancer starts in the upper, middle, or lower third of the esophagus. These numbers don’t apply if the cancer is restaged later on. Stage 4: When cancer spreads from the initial site to other organs or areas of the body, it is referred … How the cancer stage might affect a person’s prognosis. Doctors are always learning more about cancer, how it grows and spreads, and how best to treat it. For reprint requests, please see our Content Usage Policy. This can be done the same way as clinical staging (if surgery hasn’t been done yet), which can help determine what type of surgery should be done. Cancer staging can be divided into a clinical stage and a pathologic stage. Once the values for T, N, and M (and any other factors that affect stage) have been determined, they are combined to assign an overall stage. As a rule, the lower the number, the less the cancer has spread. The TNM system helps describe cancer in great detail. Imagine a world free from cancer. For more information, see Cancer Staging. The goal might be to try to shrink the tumor before surgery (in which case the treatment is called neoadjuvant therapy), or it might be done as the main treatment if it’s not clear that surgery is going to be an option. Doctors often write the stage down in Roman numerals. Imagine a world free from cancer. What are the stages of death from cancer? This process is called staging. There are 5 stages: s… If you have any questions about your stage, please ask your doctor to explain it to you in a way you understand. Survival rates can’t tell for sure what will happen with any particular person, because many other factors can also affect prognosis (see below). Until we do, we’ll be funding and conducting research, sharing expert information, supporting patients, and spreading the word about prevention. It is used to stage most pancreatic cancers except for well-differentiated pancreatic neuroendocrine tumors (NETs), which have their own staging system. Sometimes stages are subdivided as well, using capital letters (for example, stage III might be subdivided into stages IIIA and IIIB). Help make it a reality. For some cancer types, TNM categories may also have subcategories. This term is used to describe some cancers that might have just reached nearby blood vessels, but which the doctors feel might still be removed completely with surgery. Tumor markers are substances that can sometimes be found in the blood when a person has cancer. Cancer stages. There are different scales to determine different stages, according to the symptoms and rate of metastasis. But in some cases, it is staged again after treatment has started. Stage 3 colon cancer is classified as stage 3A, 3B, and 3C: 3A stage. Grade can be important because cancers with more abnormal-looking cells tend to grow and spread faster. If you’re not sure about the stage of your cancer or what it might mean for you, ask your doctor to explain it to you in a way you understand. As a rule, the lower the number, the less the cancer has spread. For example: Along with the type of cancer a person has, the stage of the cancer is one of the most important factors when doctors try to determine a person’s prognosis (outlook). Doctors also use a cancer's stage when talking about survival statistics. For example, in prostate cancer, the level of prostate-specific antigen (PSA) in the blood is taken into account in assigning a stage. Once a person’s T, N, and M categories have been determined, this information is combined in a process called stage grouping to assign an overall stage. Whether you or someone you love has cancer, knowing what to expect can help you cope. The tumor has grown to or through the muscular layers of the colon and is found in nearby lymph nodes. Higher numbers mean the cancer is more advanced. As a rule, the lower the number, the less the cancer has spread. Surgery might still be done, but the goal would be to prevent or relieve symptoms, not to try to cure the cancer. A higher number, such as stage IV, means a more advanced cancer. Stages are used to describe the spread of solid tumours, like breast, bowel or lung cancers. Some of the cells in this position poses little. Staging might be done after this first treatment to help measure the cancer’s response to treatment. New York, NY: Springer; 2017:337. Even when the grade doesn’t affect a cancer’s stage, it might still affect a person’s outlook and/or treatment. The stage assigned at diagnosis is still the one that is most important when discussing statistics like survival rates (described below). The cancer is confined to the pancreas and is no bigger than 2 cm (0.8 inch) across (T1) AND it has spread to no more than 3 nearby lymph nodes (N1). 3. For most cancers, the stage is a Roman numeral from I (1) to IV (4). ), endoscopy exams, and any biopsies that are done before treatment starts. Those broad groups are based on a much more detailed system that includes specific information about the … If so, where and how many? Most of the time, Grade 3 pancreas cancers tend to have a poor prognosis (outlook) compared to Grade 1 or 2 cancers. American Cancer Society medical information is copyrighted material. The blood cancer 1st stage includes the enlargement of the lymph nodes. Doctors answer the following questions based on the results from diagnostic tests, imaging scans, and surgery to remove or get a sample of the tumor. Tax ID Number: 13-1788491. Low-grade cancers (G1) tend to grow and spread more slowly than high-grade (G3) cancers. Grade 3 (G3) means the cancer looks very abnormal. When trying to determine how much and where the cancer is in the body, doctors first look at the primary (main) tumor, which is where the cancer started. Cancer.org is provided courtesy of the Leo and Gloria Rosen family. 8th ed. Squamous cell esophageal cancers are staged differently from esophageal adenocarcinomas. Because the type of cancer cell can affect treatment and outlook, it can be a factor in staging. (Node, N) 3. For instance, some cancers may not have an N3 category. For many types of cancer, doctors commonly use the TNM system of the American Joint Committee on Cancer (AJCC) to describe a cancer’s stage. In general, the lower the number, the less the cancer has spread. Our team of expert journalists brings you all angles of the cancer story – from breaking news and survivor stories to in-depth insights into cutting-edge research. The cancer is confined to the pancreas and is larger than 2 cm (0.8 inch) but no more than 4cm (1.6 inches) across (T2). This is the percentage of people with a certain type and stage of cancer who are still alive a certain amount of time (usually 5 years) after being diagnosed. Cancers with similar stages tend to have a similar outlook and are often treated in much the same way. Research. Blood levels of tumor markers: For some cancers, the blood levels of certain substances (called tumor markers) can affect the stage of the cancer. Making Strides Against Breast Cancer Walks, Common Questions About the COVID-19 Outbreak, Testing Biopsy and Cytology Specimens for Cancer, Depending on where the cancer is located, a, A clinical stage is noted with “c” (for example, cT1), A pathological stage is noted with “p” (for example, pN2), For cancers that are restaged after neoadjuvant therapy (or other therapy), a “y” might be used in front of the category (for example, ycT1 or ypT2), For cancers that are restaged after recurrence or progression of the cancer, an “r” might be used in front of the category (for example, rcT1 or rpT2), Staging systems other than the TNM system are often used for, The International Federation of Gynecologists and Obstetricians (FIGO) has a staging system for, Whether the cancer cells have changes in certain genes, chromosomes, or proteins. The cancer is confined to the pancreas and is bigger than 4 cm (1.6 inches) across (T3). Sometimes, the pathological stage is different from the clinical stage (for instance, if the surgery shows the cancer has spread more than was seen on imaging tests). If so, where and how much?The results are combined to determine the stage of cancer for each person. 2018 Jan;18(1):2-11. doi: 10.1016/j.pan.2017.11.011. Depending on the cancer type, other important prognostic factors might include: If you have questions about survival rates and how they might be affected by the stage of your cancer or other factors, be sure to talk to your cancer care team. The American Cancer Society couldn’t do what we do without the support of our partners. New York, NY: Springer; 2017: 715-725. Most cancers are staged from 0 to 4, with the higher number representing the most advanced disease. For example, the best treatment for an early-stage cancer may be surgery or radiation, while a more advanced-stage cancer may need treatments that reach all parts of the body, such as chemotherapy, targeted drug therapy, or immunotherapy. Doctors also use a cancer's stage when talking about survival statistics. Others can be used to describe several types of cancer. Stage I cancers are less advanced and often have a better prognosis (outlook). Become a volunteer, make a tax-deductible donation, or participate in a fundraising event to help us save lives. Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing. A higher number, such as stage IV, means a more advanced cancer. What does it take to outsmart cancer? Cancer.org is provided courtesy of the Leo and Gloria Rosen family. The cancer is confined to the pancreas and is bigger than 4 cm (1.6 inches) across (T3) AND it has spread to no more than 3 nearby lymph nodes (N1).
