The stage of the cancer helps you and your doctor:. Breast cancer stage is usually expressed as a number on a scale of 0 through IV — with stage 0 describing non-invasive cancers that remain within their original location and stage IV describing invasive cancers that have spread outside the breast to other parts of the body. 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.
For most types of cancer, doctors need to know how much cancer there is and where it is among other things to help determine the best treatment options. 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. Sometimes, cancers with different stages might be treated the same way, or cancers with the same stage might be treated in different ways. Many factors determine the best treatment options for each person. Not all cancers are staged.
Stages of Colon Cancer
Staging is a way of describing the size of a cancer and how far it has grown. When doctors first diagnose a cancer, they carry out tests to:. Cancer staging may sometimes includes the grade of the cancer. This describes how similar a cancer cell is to a normal cell. Doctors may recommend a local treatment, such as surgery or radiotherapy if your cancer is just in one place. This could be enough to get rid of the cancer completely. A local treatment treats only an area of the body.
Skip to Content. Staging helps describe where a cancer is located, if or where it has spread, and whether it is affecting other parts of the body. Staging may not be complete until all of these tests are finished. Knowing the stage helps the doctor:. 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. Are there any biomarkers or tumor markers linked to the cancer that may make it more or less likely to spread?
These tests show whether the breast cancer has spread to other parts of the body. This is called staging. It helps you and your health care team decide which treatment option is best for you. The staging system most commonly used for breast cancer is the TNM system. In this system, letters and numbers are used to describe how big the tumour is T , whether the cancer has spread to nearby lymph nodes N , and whether the cancer has spread to the bones or other organs, i. In , the staging system was updated to include details about the tumour such as oestrogen and progesterone receptor status, HER2 status and grade of the cancer.
Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include being female, obesity , a lack of physical exercise, alcoholism , hormone replacement therapy during menopause , ionizing radiation , an early age at first menstruation , having children late in life or not at all, older age, having a prior history of breast cancer, and a family history of breast cancer. The balance of benefits versus harms of breast cancer screening is controversial. A Cochrane review found that it was unclear if mammographic screening does more harm than good, in that a large proportion of women who test positive turn out not to have the disease. Outcomes for breast cancer vary depending on the cancer type, the extent of disease , and the person's age. Breast cancer most commonly presents as a lump that feels different from the rest of the breast tissue.
Cancer occurs when changes called mutations take place in genes that regulate cell growth. The mutations let the cells divide and multiply in an uncontrolled way. Breast cancer is cancer that develops in breast cells. Typically, the cancer forms in either the lobules or the ducts of the breast. Lobules are the glands that produce milk, and ducts are the pathways that bring the milk from the glands to the nipple.
Breast Cancer Stages
The stage refers to the extent of the cancer and how far it has spread. Staging colon cancer is essential to determine the best treatment approach. Colon cancer is typically staged based on a system established by the American Joint Committee on Cancer called the TNM staging system. Within each category, the disease is classified even further and assigned a number or a letter to indicate the extent of the disease.
Cancer staging is the process of determining the extent to which a cancer has developed by growing and spreading. Contemporary practice is to assign a number from I to IV to a cancer, with I being an isolated cancer and IV being a cancer that has spread to the limit of what the assessment measures. The stage generally takes into account the size of a tumor , whether it has invaded adjacent organs , how many regional nearby lymph nodes it has spread to if any , and whether it has appeared in more distant locations metastasized. The staging system is not applicable to astrocytoma , which is instead expressed as "grade I-IV".

Stages of cancer
Халохот сразу же увидел Беккера: нельзя было не заметить пиджак защитного цвета да еще с кровавым пятном на боку. Светлый силуэт двигался по центральному проходу среди моря черных одежд. Он не должен знать, что я. - Халохот улыбнулся. - Может считать себя покойником. И он задвигал крошечными металлическими контактами на кончиках пальцев, стремясь как можно быстрее сообщить американским заказчикам хорошую новость.
Не упусти. - Спасибо, шеф. Голос шефа из смешливого вдруг стал жестким: - Сьюзан, я звоню потому, что ты нужна мне .

Люди, занимавшиеся нелегальной деятельностью с использованием электронной почты, быстро убедились в том, что их секреты больше не являются их частным достоянием. ФБР, Налоговое управление, Агентство по борьбе с наркотиками и другие правоохранительные агентства США - с помощью опытных штатных хакеров - сумели арестовать и предать суду гораздо больше преступников. Разумеется, когда пользователи компьютеров во всем мире обнаружили, что американское правительство имеет широкий доступ к их электронной почте, раздались возмущенные голоса. Даже те, кто использовал электронную почту лишь для развлечения, занервничали из-за вторжения в их частную жизнь.
