Stages of Breast Cancer

There are several different stages of breast cancer. After someone is diagnosed with cancer, medical doctors will perform a set of test to find out if cancer has spread from the particular location to the rest of the breast or other parts of the body.

There are three different ways that cancer can spread inside the body. Cancer may spread from where it started to other regions of the body. There are four different stages of breast cancer, Stages 0 through four, Stages I, II, IIA, IIB, I11 (lllA IIIB, IIIC), and IV.

After breast cancer is diagnosed, there is a process to find out whether cancer has spread inside the breast to other parts of the body through different stages. The information gathered in these test determines the stage of breast cancer. It is important to find out the stage of cancer that a person has to plan the proper treatment.

We will discuss the following test and procedures that may be used to determine the stage at which the individual has cancer.

The sentinel lymph node biopsy. In this system, the sentinel lymph node is removed. The sentinel lymph node is the first lymph node to get lymphatic drainage from the tumor. Lymphatic drainage is a type of gentle massage that is supposed to encode natural drainage of the lumps and brings the waste products away from the tissues towards the heart. A radioactive substance and blue dye are injected near the tumor.The material of dye flows through the lymph ducts to the lymph nodes. The first lymph node gets substances, and dye flows are removed.

Stage O

Stage 0 is used to indicate noninvasive breast cancer, such as DCIS (ductal carcinoma in situ). In stage 0, there is not any cancer cells or non-cancerous abnormal cells breaking out of the part of the breast that the began. There is also no evidence of cells invading neighbouring normal tissue.
IAIBStage 1

Stage 1 is invasive breast cancer in which cancer cells brake through to or start to invade normal surrounding breast tissue) Stage 1 is broken into subcategories known as IA and IB

Stage IA defines invasive breast cancer in which:

The tumor measured up to 2 centimeters AND
Cancer has not spread outside the breast – There are no lymph nodes evident.

Stage IB details invasive breast cancer in which:

There is not a tumor in the breast; however there are are cancer cells – that are larger, 0.2 millimeters but no larger than 2 millimeters – are found in the lymph node Or
There is a tumor in the breast smaller than two centimeters, and there are small groups of cancer cIIAells, larger than 0.2 millimeters, but smaller than 2 millimeters – within the lymph nodes.

Microscopic invasion is possible in stage 1 breast cancer. Cancer cells start to invade the tissue outside the lining of the duct or lobule. Invading cancer can not measure more than 1 millimeter, during the microsipic invasion.

Stage II

In Stage II is divided in into two categories, called IIA and IIB,

Stage IIA details invasive breast cancer in which:

  • No tumors are found in the breast. However, there is cancer found that is larger than two millimeters and found in 1 to 3 axillary lymph nodes under the arm or lump nodes near the breastbone OR
  • The tumor measures two centimeters or less and has spread from the axillary lymph nodes OR
  • The tumor is larger than two centimeters but no larger than five centimeters and has not spread to axillary lymph nodes.

Stage IIB describes cancer invasive cancer that:

  • The tumor is larger than two centimeters but is not any larger than five centermost; small groups of cancerous cells larger than 0.2 millimeters but are not larger than two millimeters, which are fouIIBnd in the lymph nodes OR
  • The tumor is larger than two centimeters but is not larger than five centimeters, cancer has spread to one to three axillary lymph nodes or lymph nodes near the breastbone OR
  • the tumor is larger than five centimeters but has not spread to the axillary lymph nodes.

Stage III

Stage III is divided into three distinct categories called IIIA, IIIB, and IIIC.

Stage IIIA describes invasive breast cancer that is either:

  • No tumor is found in the breast, or the tumor can be any size. However, there is cancer found in 4, to 9 axillary lymph nodes or the lymph nodes are located near the breast bound OR
  • The tumor is IIIAgreater than five centimeters, and there are small groups of cancerous cells, bigger than 0. 2 millimeters but not larger than two millimeters and are found in the lymph nodes OR
  • The tumor is larger than five centers, cancer has spread to one to three axillary lymph node or the lymph nodes near the breastbone.

Stage IIIB details invasive breast cancer in which:

  • The tumor can be any measurement and has spread to the chest wall or skin and causes swelling or an ulcer AND
  • Could have spread to up to 9 axillary lymph nodes OR
    may have spread to lymph nodesIIIB near the breastbone.
  • Inflammation from breast cancer is considered at least stage IIIB. Theis goes along with;
    the red color of breast skin
    breast feel swarm and may be swollen
    On the skin, there are cancer cells have that have spread to lymph nodes

Stage IIIC describes invasive breast cancer that which:

  1. There may be no indication of cancer in the breast, or there may be a tumor, which can spread to the chest wall and the skin of the breast.
  2. Cancer has spread to 10 or more axillary lymph nodes OR
  3. Cancer has spread to axillary lymph nodes or lymph nodes near the breastbone.IIIC

Stage IV

download (1)Stage IV is when the invasive breast cancer has spread beyond the breast to nearby lymph nodes to other organs, such as the lungs, skin, bones, liver, and the brain,
This may also be called, advanced stage or mechanistic stage of cancer, IV cancer a be a reoccurrence of previous cancer that has spread to other parts of the body.
