What are the stages of breast cancer? How are these stages diagnosed? What is the most dangerous stage? Here are the answers to these questions in detail in the following paragraphs, in addition to some important information and statistics related to these stages, so be sure to follow up.
Breast cancer stages
Be divided Breast cancer To stages according to the size of the tumor and its prevalence, and in the event of a large size of cancer or its spread of nearby tissues or organs, this cancer is classified at the highest levels, and to determine the stage of cancer the following factors must be verified:
- Is cancer spread or not?
- The size of the tumor or cancerous mass.
- Has cancer reached the lymph nodes or not?
- Has cancer spread and reached nearby tissues and organs or not?
The stages of breast cancer include:
1- Breast cancer, the first stage
This stage is divided into the following:
- Stage 1A: The width of the tumor is 2 cm or less, and the lymph nodes are not affected.
- Stage 1B: Cancer is found in the nearby lymph nodes, there is no lump in the breast, or a mass of less than 2 cm is discovered.
2- Breast cancer, the second stage
This stage is divided into the following:
- Stage 2A: During this stage the tumor is less than 2 cm, and it has spread to a contract or 3 lymph nodes close, or its size is between 2 to 5 cm, and has not spread to any lymph nodes.
- Stage 2B: The rum is between 2 to 5 cm, has spread to a knot or 3 lymph nodes in the armpits, or is greater than 5 cm and has not spread to any lymph nodes.
The cure rate for breast cancer in the second stage
Breast cancer in the second stage is considered an early stage, where cancer did not spread significantly outside the breast and lymph nodes, and according to some available data, the average survival rate for 5 years after diagnosis of breast cancer is the second stage, 93%, people who are diagnosed early have increased their recovery rates , Compared to late diagnosis and treatment.
3- Breast cancer, the third stage
This stage is divided into the following:
- Stage 3A: During this stage, the cancer has spread to 4 or 9 lymph nodes in the armpits, or has caused enlarged lymph nodes in the breast, and the initial tumor can be of any size (usually greater than 5 cm).
- Stage 3B: During this stage, the tumor has spread to the chest or skin wall, and it may have spread in the lymph nodes.
- Stage 3C: Cancer is found within 10 or more epithelial lymph nodes, as it is found in the lymph nodes near the collarbone and the inner lymph nodes of the breast.
The third stage breast cancer recovery rate
According to the American Cancer Society, the average survival rate for 5 years after diagnosis of breast cancer is the third stage, 86%, and this means that among the 100 people with this stage of cancer, 85 people can survive, for at least 5 years.
4- Breast cancer, stage four
This stage is considered the most advanced stage of breast cancer, and means that the tumor has passed the breast and moved to other body parts such as bones, lung and liver. At this stage, the tumor may be of any size, in some cases it may have spread to the lymph nodes, and in other cases it did not spread.
It is worth noting that the transmission of the tumor from the breast to other organs does not change this type of cancer. If the cancer cells move to the lung from the breast, the cancer is classified as breast cancer and not lung cancer, and the tests determine its progress.
The most prominent symptoms of breast cancer in the fourth stage include:
- The presence of a tumor or mass in the breast.
- Changes in the breast skin.
- Breast nipple changes.
- The appearance of redness and swelling in the breast or breast skin.
- Fatigue and fatigue.
- Having a dry cough.
- Feeling of chest pain.
- Anorexia.
- Nausea.
- Vision disorders.
- Difficulty in balance.
How long does a stage IV breast cancer patient live?
According to the American Cancer Society ACS, the average survival rate for 5 years after the diagnosis of breast cancer is the fourth stage 28%, and this percentage is considered very low, compared to the survival rate associated with other stages of breast cancer, which in some stages may reach 90%.

The most dangerous stages of breast cancer
The fourth stage of breast cancer is the most dangerous stage of breast cancer. At this stage, cancer has spread outside the breast and near lymph nodes to other organs of the body such as the lungs, distant lymph nodes, skin, bones, liver, and others. This stage is usually described as diffuse or diffuse breast cancer.
Breast cancer screening tests
Tests and analyzes used to determine the stages of breast cancer include:
- Physical examination: To know the information necessary for diagnosis and to choose the appropriate treatment.
- Medical reports: It is prepared in case of surgery to remove cancer and affected lymph nodes.
- Cancer cell evaluation tests: This includes biopsy or surgical procedures to take a sample for examination and to know the progress of cancer.
- Blood tests: It is not used to determine the stage of cancer specifically, but is used to give the doctor a comprehensive idea of public health and evidence that may help him determine the stage.
- Breast imaging tests: include Mammugram examination AndMRI And others.
- Other imaging tests such as, bone examination and tomographyPET tomography.
A breast cancer patient does not need all of the above-mentioned tests, as the doctor selects the necessary and necessary examinations according to the patient's condition.
