Staging And Grading For Stage 3 Cancer
Staging is an important factor in determining cancer treatment options, since it establishes the tumors size and spread within the body. Staging is used for most cancers, but not all. Cancers in and near the brain, for example, dont use a defined staging system because their likelihood of spreading is low.
In general, cancer falls within stages 1 through 4. Some types may be stage 0, meaning there are cancerous cells in a layer of tissue, but they havent grown or spread.
Most cancers are staged using some form of the TNM system. Doctors may also use the TNM system to help determine the extent of certain cancers in each stage. The TNM system stands for:
- T , for the size of the original tumor
- N , whether the cancer is present in the lymph nodes
- M , whether the cancer has spread to other parts of the body
Some cancers, especially liquid cancers, are staged using different established protocols. The Binet and Rai systems, for example, are used to stage certain types of leukemia. Cancers of the female reproductive system, such as cervical cancer and ovarian cancer, are staged using the FIGO staging system, designed by the International Federation of Gynecology and Obstetrics .
Regardless of the system used, the first step for doctors staging cancer is to gather information about it. Some tests or procedures that may be involved as your care team is staging your cancer include:
When it comes to grading, tumors generally may be referenced in the following ways.
Determining The True Stage Of Breast Cancer
All the diagnostic tests and scans up to this point have been critical for helping your doctors understand your disease. But the exact stage of cancer cant be determined until surgery happens which is sometimes referred to surgical staging or pathological staging.
Breast surgery is usually the first step in Stages 0-2, and sometimes Stage 3 breast cancer. Surgery allows your surgeon to see whats happening inside your body. It also allows them to remove cancerous tissues which is an important step in preventing the cancer from spreading and determining next steps for your treatment.
If surgery cant be done right away or at all, a clinical stage is given instead based on diagnostic imaging test results, biopsy pathology results, and a physical exam.
How Is Breast Cancer Recurrence Managed Or Treated
Your treatment depends on the type of cancer recurrence, as well as past treatments. If cancer develops in a reconstructed breast, your surgeon may want to remove the breast implant or skin flap.
Treatments for local and regional breast cancer recurrence may include:
- Mastectomy: Your surgeon removes the affected breast and sometimes lymph nodes.
- Chemotherapy:Chemotherapy circulates in blood, killing cancer cells.
- Hormone therapy:Tamoxifen and other hormone therapies treat cancers that thrive on estrogen .
- Immunotherapy:Immunotherapy engages your bodys immune system to fight cancer.
- Radiation therapy: High-energy X-ray beams damage and destroy cancer cells.
- Targeted therapy: Treatments target specific cancer cell genes or proteins.

How Does Staging Relate To Types Of Breast Cancer
In addition to cancer stage, doctors will determine the tumor grade and subtype.
Tumors are graded on a scale of 1 to 3, based on how abnormal the cells appear compared to normal cells. The higher the grade, the more aggressive the cancer, meaning that it tends to be growing quickly.
The subtype is important because treatment and outlook will vary depending on which subtype of breast cancer that you have. Subtypes include:
What Is Stage Iii
In this stage, I tell my patients the real war against the cancer begins, Cruz said. Spreading is much more advanced.
According to Cruz, stage III is unique in that it has three subcategories: IIIA, IIIB and IIIC.
IIIA has tumors all larger than five millimeters and has spread to lymph nodes. Cruz said the higher number of lymph nodes with cancer cells, the more advanced it is.
In stage IIIB, the tumor has spread to the chest wall and skin of the breast. In many cases, this spreading can result in swelling or ulcers. The cancer cells have also spread to nine lymph nodes.
There is advanced spreading in stage IIIC: the cancer has spread to the chest wall, skin of the breast, 10 or more lymph nodes and the collarbone.
In stage III, yes there is advanced spreading. Yes it is harder to treat, but not untreatable, Cruz said. Thats what we tell our patients, although the spreading is scary, we can still fight it.

Cancer May Spread From Where It Began To Other Parts Of The Body
When cancer spreads to another part of the body, it is called . Cancer break away from where they began and travel through the lymph system or blood.
- Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a in another part of the body.
- Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor in another part of the body.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bone, the cancer cells in the bone are actually breast cancer cells. The disease is metastatic breast cancer, not .
Treatment Options For Stage Iv Breast Cancer
For women with stage IV breast cancer, systemic therapies are the main treatments. These may include:
- Some combination of these
Treatment can often shrink tumors , improve symptoms, and help women live longer. These cancers are considered incurable.

Stage Iii: Locally Advanced
Locally advanced breast cancer includes tumors larger than 5 cm, extensive regional lymph node involvement, direct involvement of underlying chest wall or skin, tumors considered inoperable but without distant metastases, and inflammatory breast cancer. Induction chemotherapy followed by local therapy is becoming the standard of care. Five-year survival can be achieved in 55 percent of patients presenting with noninflammatory LABC.54 The most important prognostic factors are response to induction chemotherapy and lymph node status.
How Grade Affects Treatment Options
Your treatment team will consider the grade of your cancer when deciding which treatment to offer you.
If you have grade 3 breast cancer, youre more likely to be offered chemotherapy. This is to help destroy any cancer cells that may have spread as a result of the cancer being faster growing.
Chemotherapy is less likely for grade 1 and grade 2 cancers.
The grade of your cancer alone will not determine what treatment youre offered. Your treatment team will consider the grade alongside all other information about your cancer when deciding on the best treatment options for you.

Radiation Therapy And Mastectomy
Most women who have a mastectomy dont need radiation therapy if theres no cancer in the lymph nodes.
In some cases, radiation therapy is used after mastectomy to treat the chest wall, the axillary lymph nodes and/or the lymph nodes around the collarbone.
For a summary of research studies on mastectomy versus lumpectomy plus radiation therapy and overall survival in early breast cancer, visit the Breast Cancer Research Studies section.

Ovarian Ablation Or Suppression
In women who have not yet experienced the menopause, oestrogen is produced by the ovaries.
Ovarian ablation or suppression stops the ovaries working and producing oestrogen.
Ablation can be done using surgery or radiotherapy. It permanently stops the ovaries from working and means you’ll experience the menopause early.
Ovarian suppression involves using a medicine called goserelin, which is a luteinising hormone-releasing hormone agonist .
Your periods will stop while you’re taking it, although they should start again once your treatment is complete.
If you’re approaching the menopause , your periods may not start again after you stop taking goserelin.
Goserelin comes as an injection you have once a month.

Radiation For Breast Cancer
Radiation therapy is a common treatment for women who have had breast-conserving surgery. It is also sometimes given to women who have had a mastectomy, particularly if there has been spread of the tumor to the chest wall muscles or skin, or to the reginal lymph nodes. This treatment uses high-energy rays to destroy remaining cancer cells. Radiation therapy can be given externally or internally. External radiation therapy is given in a clinic, usually five days a week for several weeks. This is the most common kind of radiation therapy used to treat breast cancer. However, in some cases, internal radiation therapy can be used. This involves the placement of radioactive material directly into the breast tissue through thin tubes. After a short time period, the material is removed. This can be repeated on a daily basis for a week. Administering radioactive material inside the body is known as brachytherapy.
The Types Of Radiotherapy
The type of radiotherapy you have will depend on the type of breast cancer and the type of surgery you have. Some women may not need to have radiotherapy at all.
Types of radiotherapy include:
- breast radiotherapy after breast-conserving surgery, radiation is applied to the whole of the remaining breast tissue
- chest-wall radiotherapy after a mastectomy, radiotherapy is applied to the chest wall
- breast boost some women may be offered a boost of high-dose radiotherapy in the area where the cancer was removed however, this may affect the appearance of your breast, particularly if you have large breasts, and can sometimes have other side effects, including hardening of breast tissue
- radiotherapy to the lymph nodes where radiotherapy is aimed at the armpit and the surrounding area to kill any cancer that may be in the lymph nodes
How Often Does Stage 1 Breast Cancer Come Back After Treatment
If stage 1 cancer is treated comprehensively, it rarely comes back. A new, unrelated breast cancer is more likely to emerge after stage 1 breast cancer is treated than a recurrence. Your healthcare provider will recommend a surveillance schedule for you so that new breast cancer or a recurrence can be identified and treated as quickly as possible.
More Information About The Tnm Staging System
The T category describes the original tumor:
- TX means the tumor can’t be assessed.
- T0 means there isn’t any evidence of the primary tumor.
- Tis means the cancer is “in situ” .
- T1, T2, T3, T4: These numbers are based on the size of the tumor and the extent to which it has grown into neighboring breast tissue. The higher the T number, the larger the tumor and/or the more it may have grown into the breast tissue.
The N category describes whether or not the cancer has reached nearby lymph nodes:
- NX means the nearby lymph nodes can’t be assessed, for example, if they were previously removed.
- N0 means nearby lymph nodes do not contain cancer.
- N1, N2, N3: These numbers are based on the number of lymph nodes involved and how much cancer is found in them. The higher the N number, the greater the extent of the lymph node involvement.
The M category tells whether or not there is evidence that the cancer has traveled to other parts of the body:
- MX means metastasis can’t be assessed.
- M0 means there is no distant metastasis.
- M1 means that distant metastasis is present.

What Is Stage Iii Breast Cancer
In stage III breast cancer, the cancer has spread further into the breast or the tumor is a larger size than earlier stages. It is divided into three subcategories.
Stage IIIA is based on one of the following:
- With or without a tumor in the breast, cancer is found in four to nine nearby lymph nodes.
- A breast tumor is larger than 50 millimeters, and the cancer has spread to between one and three nearby lymph nodes.
In stage IIIB, a tumor has spread to the chest wall behind the breast. In addition, these factors contribute to assigning this stage:
- Cancer may also have spread to the skin, causing swelling or inflammation.
- It may have broken through the skin, causing an ulcerated area or wound.
- It may have spread to as many as nine underarm lymph nodes or to nodes near the breastbone.
In stage IIIC, there may be a tumor of any size in the breast, or no tumor present at all. But either way, the cancer has spread to one of the following places:
- ten or more underarm lymph nodes
- lymph nodes near the collarbone
- some underarm lymph nodes and lymph nodes near the breastbone
- the skin
Talazoparib As Neoadjuvant Treatment In Early
In the de-escalation era, the use of talazoparib monotherapy in the neoadjuvant setting is being studied and may become a real option. A small feasibility study of only 13 patients demonstrated that the use of single-agent talazoparib for 2 months before neoadjuvant therapy and definitive surgery achieved tumor volume decrease in 88% of patients, and all patients were able to receive standard chemotherapy regimens after talazoparib with no grade 4 toxicities seen. An expansion of this cohort was presented at the American Society of Clinical Oncology Annual Meeting in 2018 , which evaluated the use of talazoparib before surgery for 6 months with 20 enrolled patients. Ten of the 19 patients who underwent surgery achieved pathologic complete response, only 1 patient experienced grade 4 toxicity, and 9 dose reductions were required. A larger nonrandomized, single-arm phase II trial evaluating talazoparib as a single agent for neoadjuvant treatment in early triple-negative patients with BRCA mutations is ongoing.

What Should A Person With Stage 3 Breast Cancer Expect From Treatment
Stage 3 treatment options vary widely and may consist of mastectomy and radiation for local treatment and hormone therapy or chemotherapy for systemic treatment. Nearly every person with a Stage 3 diagnosis will do best with a combination of two or more treatments.
Chemotherapy is always given first with the goal to shrink the breast cancer to be smaller within the breast and within the lymph nodes that are affected. This is known as neoadjuvant chemotherapy.
Other possible treatments include biologic targeted therapy and immunotherapy. There may be various clinical trial options for interested patients with Stage 3 breast cancer.
What Are The Different Grades Of Breast Cancer
There are three grades of invasive breast cancer:
- Grade 1 looks most like normal breast cells and is usually slow growing
- Grade 2 looks less like normal cells and is growing faster
- Grade 3 looks different to normal breast cells and is usually fast growing
Sometimes the grade given to a cancer after a biopsy can change after surgery. This is because after surgery theres more tissue for the pathologist to look at, which can give them more detailed information about the cancer.

What Questions Should I Ask My Healthcare Provider
You may want to ask your provider:
- What type of breast cancer recurrence do I have?
- Has the cancer spread outside the breast?
- What stage is the breast cancer?
- What is the best treatment for this type of breast cancer?
- What are the treatment risks and side effects?
- Should I look out for signs of complications?
A note from Cleveland Clinic
Most breast cancer recurrences respond well to treatments. You may be able to try new drugs or combination therapies in development in clinical trials. Your healthcare provider can discuss the best treatment option based on your unique situation.

Stage 3b Breast Cancer
Stage 3B breast cancer means a tumour of any size that has spread to other tissues near the breast such as skin, muscles, or ribs. At this stage, the tumour may or may not have spread to the lymph nodes. However, the cancer has not spread to other distant parts of the body.
Cancer that has spread to the skin of the breast might be inflammatory breast cancer, a rare form of cancer which can be aggressive and challenging to treat.

Will The Nhs Fund An Unlicensed Medicine
It’s possible for your doctor to prescribe a medicine outside the uses it’s licensed for if they’re willing to take personal responsibility for this ‘off-licence’ use of treatment.
Your local clinical commissioning group may need to be involved, as it would have to decide whether to support your doctor’s decision and pay for the medicine from NHS budgets.

Local Or Regional Treatments For Stage Iv Breast Cancer
Although systemic drugs are the main treatment for stage IV breast cancer, local and regional treatments such as surgery, radiation therapy, or regional chemotherapy are sometimes used as well. These can help treat breast cancer in a specific part of the body, but they are very unlikely to get rid of all of the cancer. These treatments are more likely to be used to help prevent or treat symptoms or complications from the cancer.
Radiation therapy and/or surgery may also be used in certain situations, such as:
- When the breast tumor is causing an open wound in the breast
- To treat a small number of metastases in a certain area, such as the brain
- To help prevent bone fractures
- When an area of cancer spread is pressing on the spinal cord
- To treat a blood vessel blockage in the liver
- To provide relief of pain or other symptoms
In some cases, regional chemo may be useful as well.
If your doctor recommends such local or regional treatments, it is important that you understand their goalwhether it is to try to cure the cancer or to prevent or treat symptoms.
