The 4 Stages Of Breast Cancer

Stage 2 Breast Cancer

What Are the Treatment Options for Stage 4 Breast Cancer?

Stage 2 breast cancer is divided into two groups:

Stage 2A can mean:

No cancer is seen in the breast but cancer is found in one to three lymph nodes under the arm or near the breastbone

The cancer in the breast is 2cm or smaller and cancer is found in one to three lymph nodes under the arm or near the breastbone.

The cancer in the breast is larger than 2cm but smaller than 5cm and no cancer is found in the lymph nodes under the arm.

Stage 2B can mean:

The cancer in the breast is larger than 2cm but smaller than 5cm. Cancer is found in one to three lymph nodes under the arm or near the breastbone

The cancer in the breast is larger than 5cm and no cancer is found in the lymph nodes under the arm.

What Are The Signs Of Breast Cancer

nipple changes, such as flattening, inversion, and dimpling. Other symptoms that may appear throughout the body include: When breast cancer cells move to other areas of the body, they remain as breast cancer cells. For example, breast cancer that has spread to the lungs is still breast cancer, not lung cancer.

Stage Groups For Breast Cancer

Doctors assign the stage of the cancer by combining the T, N, and M classifications , the tumor grade, and the results of ER/PR and HER2 testing. This information is used to help determine your prognosis . The simpler approach to explaining the stage of breast cancer is to use the T, N, and M classifications alone. This is the approach used below to describe the different stages.

Most patients are anxious to learn the exact stage of the cancer. If you have surgery as the first treatment for your cancer, your doctor will generally confirm the stage of the cancer when the testing after surgery is finalized, usually about 5 to 7 days after surgery. When systemic treatment is given before surgery, which is typically with medications and is called neoadjuvant therapy, the stage of the cancer is primarily determined clinically. Doctors may refer to stage I to stage IIA cancer as “early stage” and stage IIB to stage III as “locally advanced.” Stage 0: Stage zero describes disease that is only in the ducts of the breast tissue and has not spread to the surrounding tissue of the breast. It is also called non-invasive or in situ cancer . Stage IA: The tumor is small, invasive, and has not spread to the lymph nodes . Stage IB: Cancer has spread to the lymph nodes and the cancer in the lymph node is larger than 0.2 mm but less than 2 mm in size. There is either no evidence of a tumor in the breast or the tumor in the breast is 20 mm or smaller .

Stage IIA: Any 1 of these conditions:

What Is The Risk Of Breast Cancer Spreading To The Brain

Brain metastasis. The risk of breast cancer spreading to the brain is generally highest in those with HER2-positive or triple-negative breast cancer, which are more aggressive subtypes of this disease. About 1015 percent of women with stage 4 breast cancer will develop brain metastasis. Symptoms include: a headache.

Research Related To Breast Cancer Classification And Implications For Clinical Practice

Breast Cancer Staging

Researcher: Dr. Sunil Lakhani, University of Queensland

Dr Lakhani recently published practice-changing findings that contributed to a new classification of a rare breast cancer, called metaplastic breast tumours, by the World Health Organisation. Learn more about his research here.

Breast cancer staging is based on tumour size, the extent that cancer has spread to other parts of the body and other clinical factors. Your doctor will use diagnostic information such as medical imaging including mammogram and/or ultrasound, and other diagnostic tests, such as a biopsy of the breast tissue and draining lymph nodes to determine the stage of the cancer.

Once the stage of the cancer has been determined, it is expressed on a scale of 0 to IV. Stage 0 refers to pre-invasive breast cancers, including ductal carcinoma in situ . Stage I and II are referred to as early breast cancer. Stage III is referred to as locally advanced breast cancer. Stage IV is called advanced or metastatic breast cancer. See above for more information.

Stage 0 refers to pre-invasive breast cancers, including ductal carcinoma in situ . This means that there are abnormal cells present, but they are contained inside the milk duct in the case of DCIS, or lobule , in the case of lobular carcinoma in situ .

Invasive breast cancer occurs when cancer cells within the milk duct or lobules break or invade through normal breast tissue. It can be Stage I, II, III or IV.

What Is Breast Cancer Staging

Breast cancer staging is the determination of the extent and spread of the cancer. An individual’s health care team uses stages to summarize the extent of the cancer in a standardized way that is recognized by all health care providers. They use this staging to determine the treatment most appropriate for the type of cancer. Cancer staging helps to determine the prognosis, or outlook, of a cancer, including rates of recurrence and survival rates.

How To Prevent Breast Cancer

There is no guaranteed way to prevent breast cancer. Reviewing the risk factors and modifying the ones that can be altered can help in decreasing the risk.

Following the American Cancer Society’s guidelines for early detection can help early detection and treatment.

There are some subgroups of women that should consider additional preventive measures.

  • Women with a strong family history of breast cancer need genetic testing such as HER2-Positive and BRCA Gene tests. Discuss this with a health care provider and meet with a genetic counselor who can explain what the testing can and cannot tell and then help interpret the results after testing.
  • Chemoprevention is the use of medications to reduce the risk of cancer. The two currently approved drugs for chemoprevention of breast cancer are tamoxifen and raloxifene , which also blocks the effect of estrogen on breast tissues. Their side effects and whether these medications are right for an individual need to be discussed with a health care provider.
  • Aromatase inhibitors are medications that block the production of small amounts of estrogen usually produced in postmenopausal women. They prevent the reoccurrence of breast cancer but are not approved at this time for breast cancer chemoprevention.
  • For a small group of patients who have a very high risk of breast cancer, surgery to remove the breasts may be an option. Although this reduces the risk significantly, a small chance of developing cancer remains.

They can detect early signs of cancerous changes. Although not all stage 4 cancer will include large tumors, many women will be able to see or feel a lump in their breast. It may exist under the armpit or somewhere else nearby. Women may also feel a general swelling around the breast or armpit areas.

What Do Cancer Stages And Grades Mean

The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.

If you’re diagnosed with cancer, you may have more tests to help determine how far it has progressed. Staging and grading the cancer will allow the doctors to determine its size, whether it has spread and the best treatment options.

A Disease No One Gets

Sadly, people donât âgetâ mets. In fact, a recent survey sponsored by Pfizer Oncology shows just how misunderstood it is. Sixty percent of the 2,000 people surveyed knew little to nothing about MBC while 72 percent believed advanced breast cancer was curable as long as it was diagnosed early. Even more disheartening, a full 50 percent thought breast cancer progressed because patients either didnât take the right treatment or the right preventive measures.

âTheyâve built an industry built on four words â early detection equals cure â and that doesnât even begin to define breast cancer,â said Schoger, who helped found Breast Cancer Social Media, a virtual community for breast cancer patients, caregivers, surgeons, oncologists and others. âWomen are blamed for the fate of bad biology.â

The MBC Alliance, a consortium of 29 cancer organizations including the biggest names in breast cancer , addressed this lack of understanding and support as well as what many patient advocates term the underfunding of MBC research in a recently published landmark report.

Ajcc Anatomic And Prognostic Stage Groups

What You Need to Know About Breast Cancer

There are three stage group tables for invasive cancer:

  • Anatomic Stage Group. The Anatomic Stage Group table is used in regions of the world where tumor grading and/or biomarker testing for ER, PR, and HER2 are not routinely available.
  • Clinical Prognostic Stage Group. The Clinical Prognostic Stage Group table is used for all patients in the United States. Patients who have neoadjuvant therapy as their initial treatment should have the clinical prognostic stage and the observed degree of response to treatment recorded, but these patients are not assigned a pathological prognostic stage.
  • Pathological Prognostic Stage Group. The Pathological Prognostic Stage Group table is used for all patients in the United States who have surgery as initial treatment and have pathological T and N information reported.

In the United States, cancer registries and clinicians must use the Clinical and Pathological Prognostic Stage Group tables for reporting. It is expected that testing is performed for grade, HER2, ER, and PR status and that results are reported for all cases of invasive cancer in the United States.

Stage 4 Breast Cancer

A person with stage 4 breast cancer, also called metastatic breast cancer, has cancer that has spread to nearby lymph nodes and also more distant lymph nodes and other organs in the body.

Stage 4 breast cancer is the most advanced stage. Stage 4 breast cancer also may be breast cancer that returned to affect other parts of the body. Cancer that has returned in other parts of the body is called recurrent metastatic breast cancer

Treatment For Stage 0 Breast Cancer

Not everyone with stage 0 breast cancer needs treatment. If tests suggest that treatment is a good idea, include:

Surgery

A lumpectomy involves removing cancerous cells from the breast. It is an option when the cells remain in one area. This is a relatively short and simple procedure, and a person should be able to go home after the surgery on the same day.

If cancerous cells appear throughout the breast, the doctor may recommend a mastectomy, which involves removing the entire breast. Plastic surgeons can rebuild the breast at the same time or a later date.

Hormone therapy

The hormone estrogen, found naturally in the body, can impact some types of breast cancer. If a person has estrogen receptor-positive or progesterone receptor-positive breast cancer, a doctor may suggest hormone treatment in addition to surgery.

In stage 1 breast cancer, the cancerous cells have invaded the surrounding breast tissue. Stage 1 breast cancer has two subcategories 1A and 1B.

Sex and gender exist on spectrums. This article will use the terms, male, female, or both to refer to sex assigned at birth. .

Stage 4 breast cancer occurs when cancerous cells spread to other areas of the body beyond the breast and local lymph nodes.

The American Cancer Society notes that breast cancer most commonly spreads to the lungs, liver, and bones. It can also spread to other organs, including the distant lymph nodes, skin, and brain.

A doctor may diagnose stage 4 breast as either a new case, referred to as de novo, or as a recurrence of a previous breast cancer.

Beyond The Shock – Chapter 5 – Types & Stages – Stage 4 Breast Cancer

Stage II describes cancer that is in a limited region of the breast but has grown larger. It reflects how many lymph nodes may contain cancer cells. This stage is divided into two subcategories.

Stage IIA is based on one of the following:

  • Either there is no tumor in the breast or there is a breast tumor up to 20 millimeters , plus cancer has spread to the lymph nodes under the arm.
  • A tumor of 20 to 50 millimeters is present in the breast, but cancer has not spread to the lymph nodes.

Stage IIB is based on one of these criteria:

  • A tumor of 20 to 50 millimeters is present in the breast, along with cancer that has spread to between one and three nearby lymph nodes.
  • A tumor in the breast is larger than 50 millimeters, but cancer has not spread to any lymph nodes.

Treatment For Stage 1 Breast Cancer

Doctors can offer a variety of for stage 1 breast cancer, although surgery is the primary treatment.

Surgery

A lumpectomy or mastectomy are both viable surgical options for people with stage 1 breast cancer. A doctor will decide what surgery is most appropriate depending on the location of the primary tumor, how large it is, the size of the breast, family history, genetics, and the persons preference.

The doctor may also carry out a biopsy on one or more lymph nodes.

After removing the tissue, they will send it to a laboratory for further tests. The results will help inform decisions on the next stage of treatment.

Radiation therapy

Radiation therapy is a standard treatment for stage 1 breast cancer. However, the decision will depend on factors such the age of the person, the type of cancer, the size of the tumor, and whether there are cancer cells in the lymph nodes.

Hormone therapy

If the breast cancer is ER+ or PR+, hormone therapy may be effective. Hormone therapy works by preventing the growth of estrogen, which helps cancer grow, by blocking estrogen from attaching to tissue and fuelling cancer growth, or both.

Hormone therapy can reach cancer cells in the breast, as well as other areas of the body, and it can reduce the risk of cancer returning.

Chemotherapy

However, the

Stage 2 breast cancer also has subcategories known as 2A and 2B.

How Do You Know If Breast Cancer Is Stage 4

Having stage 4 breast cancer means that cancer cells from the breast tissue have spread to distant parts of the body. Signs and symptoms can vary based on where the cancer has spread to. However, they may include bone pain, unexplained weight loss, loss of appetite, and severe headaches, among others.

Treatment For Stage 3 Breast Cancer

for stage 3 breast cancer may include the following, depending on the type of cancer and other factors:

  • hormone therapy
  • neoadjuvant chemotherapy before surgery to shrink a tumor

People with stage 3 breast cancer will probably need radiation therapy to kill off any remaining cancer cells. Doctors may also recommend hormone therapy, as well as additional targeted therapies, if necessary.

What Is Cancer Staging

Staging is a way of describing how extensive the breast cancer is, including the size of the tumor, whether it has spread to lymph nodes, whether it has spread to distant parts of the body, and what its biomarkers are.

Staging can be done either before or after a patient undergoes surgery. Staging done before surgery is called the clinical stage, and staging done after surgery is called the pathologic stage. Doctors use diagnostic tests to find out the cancer’s stage, so staging may not be complete until all of the tests are finished. Knowing the stage helps the doctor recommend the best kind of treatment and can help predict a patient’s prognosis, which is the chance of recovery. There are different stage descriptions for different types of cancer.

This page provides detailed information about the system used to find the stage of breast cancer and the stage groups for breast cancer, such as stage IIA or stage IV.
