I have Cancer – Diagnosis of Stage 1 Invasive Ductal Breast Cancer

Grade 1 DCIS is almost always ER and PR positive and is a very slow growing form of cancer. It can take years, even decades, to see progression of the disease. In some cases, it may take such a long time to spread beyond the breast duct that it is not an event that will happen during a persons lifetime.

Additional Grading Criteria: A Composite Total Of Tubular Nuclear And Mitotic Index Assesments

As a grade of low, intermediate or high is obtained through a composite sum by assigning a score based on the nuclear assessment, a mitotic index assessment, and a tubular assessment.

The nuclear assessment is based on the nuclear size within the invasive cells. They are described from small to medium to large in size, as well as by their uniformity in size and shape.

The tubular assessment refers to an approximate, quantitative account of the amount of cell groupings which remain in their normal tubular shape. The smaller the percentage of tubular structures in comparison to other shapes, the higher the score. Other structures to appear may include solid trabecula, vacuolated single cells, alveolar nests, and solid sheets of cells.

The mitotic index refers to evident patterns of cell division.Mitosis is a process by which a cell separates into two genetically identical daughter cells. . So, the mitotic index is assessment of the abundance of these pairs of daughter cells, measured in the count per square millimeter. Mitoses are only counted in the invasive area of the lesion .

Survival For All Stages Of Breast Cancer

Generally for women with breast cancer in England:

  • Around 95 out of every 100 women survive their cancer for 1 year or more after diagnosis
  • Around 85 out of every 100 women will survive their cancer for 5 years or more after diagnosis
  • Around 75 out of every 100 women will survive their cancer for 10 years or more after diagnosis

Cancer survival by stage at diagnosis for England, 2019Office for National Statistics

These statistics are for net survival. Net survival estimates the number of people who survive their cancer rather than calculating the number of people diagnosed with cancer who are still alive. In other words, it is the survival of cancer patients after taking into account that some people would have died from other causes if they had not had cancer.

Surgery For Invasive Ductal Carcinoma

Breast cancer treatment has evolved to offer patients more options. In addition to removing breast cancer, new aesthetic surgical approaches can enhance well-being and lessen the emotional impact of losing all or part of a breast to cancer. Comprehensive breast centers with coordinated teams of oncologic and plastic surgery practitioners can offer a wider array of options.

Surgery for IDC may include one of these procedures:

  • Lumpectomy is removal of part of the breast. It is also known as breast-conserving surgery. Lumpectomy may be followed by radiation treatments to treat any remaining cancer cells.
  • Mastectomy is removal of the breast. Mastectomy is a treatment for patients with multiple, very aggressive, or large invasive ductal tumors. It can be followed by breast reconstruction.

Treatment For Stage 3 Breast Cancer

Stages 0 &  1

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

  • chemotherapy

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

What Is The Prognosis For Invasive Ductal Carcinoma

Your doctor will discuss what you can expect based on the characteristics of the invasive ductal carcinoma and the effectiveness of your treatment.

Specialty centers such as Johns Hopkins Medicines Breast Health Services can offer integrated teams of breast cancer specialists who have skill and experience in surgery, breast reconstruction, chemotherapy, biologic targeted therapy, radiation therapy and other hormonal therapies.

Medical science is making great strides forward in treating breast cancer, allowing our surgeries to be less invasive and improving surgical outcomes and overall quality of life, Wright says.

Breast Health Services

Johns Hopkins breast health services include preventive and noncancerous surgical treatment, risk assessment, diagnostic screenings and treatment for breast cancer.

Stage 1 Invasive Tubular Breast Cancer Diagnosis

Well after 2 separate vac biopsies and countless mammograms I was today told that the second suspicious area is stage 1 invasive tubular breast cancer. I had a cry partly due to shock and partly due to family crying. Next stage is to see the surgeon and have this and the atypical ductal hyperplasia in a second area of the same breast removed, along with a couple of my lymph nodes for testing. Not really sure how I feel. Don’t really know what I want to ask. I just feel the need to share.

What Can You Tell Me About Invasive Ductal Carcinoma Stages

Staging describes how advanced your cancer is, based on the location, size and how far it has spread. There are five stages of ductal carcinoma:

  • Stage 0: The cancer is localized to your milk ducts. This stage is also known as non-invasive ductal carcinoma in situ.
  • Stage 1: The cancer has spread outside of your milk ducts to the breast tissue, but it hasnt spread to your lymph nodes. In some cases, the cancer may have spread to your lymph nodes, but not to your surrounding breast tissue.
  • Stage 2: The tumor is small and has spread to one to three of your lymph nodes. Or, the tumor is larger, but hasnt spread to any of your lymph nodes.
  • Stage 3: The cancer has often spread to more than three of your lymph nodes or is causing inflammation of most of your breast skin, but hasnt spread to other areas of your body.
  • Stage 4: The cancer has spread to your other organs, which may include your bones, liver, lungs, brain, chest wall or distant lymph nodes.

What Is A Breast Cancers Grade

Stage 1 Breast Cancer Defined By Dr. Jay Harness

Cancer cells are given a grade when they are removed from the breast and checked in the lab. The grade is based on how much the cancer cells look like normal cells. The grade is used to help predict your outcome and to help figure out what treatments might work best.

A lower grade number usually means the cancer is slower-growing and less likely to spread.

A higher number means a faster-growing cancer thats more likely to spread.

How Is Invasive Ductal Carcinoma Diagnosed

Your healthcare provider will perform a physical examination. In addition to feeling for lumps in your breast, they may also feel for swollen lymph nodes in your underarm area.

In most cases, invasive ductal carcinoma is found during routine mammograms. If your healthcare provider thinks you may have IDC, they may order other tests, including:

  • Magnetic resonance imaging . This imaging test uses radio waves and magnets to produce detailed pictures of your breast tissue.
  • Ultrasound. Using high-frequency sound waves, an ultrasound provides clear images of your internal organs and other tissues.
  • Biopsy. Your healthcare provider takes a small sample of your breast tissue with a needle. The sample is then sent to a pathology lab for further testing.

Checking The Lymph Nodes

The usual treatment is surgery to remove the cancer. Before your surgery you have an ultrasound scan to check the lymph nodes in the armpit close to the breast. This is to see if they contain cancer cells. If breast cancer spreads, it usually first spreads to the lymph nodes close to the breast.

Depending on the results of your scan you might have:

  • a sentinel lymph node biopsy during your breast cancer operation
  • surgery to remove your lymph nodes

You may have other treatments after surgery.

Also, is carcinoma in situ really cancer?

Carcinoma in situ refers to cancer in which abnormal cells have not spread beyond where they first formed. The words in situ mean in its original place. These in situ cells are not malignant, or cancerous. However, they can sometime become cancerous and spread to other nearby locations.

Also, what is carcinoma in situ? carcinoma in situ A group of abnormal cells that remain in the place where they first formed. They have not spread. These abnormal cells may become cancer and spread into nearby normal tissue. Also called stage 0 disease.

Just so, how is carcinoma in situ treated?

Radiation therapyTreatment of DCIS has a high likelihood of success, in most instances removing the tumor and preventing any recurrence. In most people, treatment options for DCIS include: Breast-conserving surgery and radiation therapy. Breast-removing surgery

Is carcinoma in situ reversible?

When an entire portion of epithelium is composed of abnormal cells and no normal epithelial cells remain, and the process is not potentially reversible, then the process has gone beyond dysplasia and is now neoplasia, which is loss of control of the cellular proliferative process.

The Prognosis For Microinvasive Carcinoma Of The Breast Is Very Good

There is universal agreement that the prognosis for ductal carcinoma discovered and intervened at a microinvasive stage, is very good. Patients with microinvasive breast cancer can typically expect a cure rate very close to 100%, with local treatment alone. Most microinvasive breast cancers will be treated by breast conserving surgery or by radical mastectomy . Adjuvant treatment is still a bit controversial, but radiotherapy is very common , while chemical and endocrine treatments are much common and will likely depend on the hormone receptor status of individual patients.

Cancer Cure And All Clear

Many people who have cancer want to know if theyre cured. You may hear words like cure and all clear in the media.

Cured means theres no chance of the breast cancer coming back. However, its not possible to be sure that breast cancer will never come back. Treatment for breast cancer will be successful for most people, and the risk of recurrence gets less as time goes on. Recurrence, unfortunately, can happen even many years after treatment, so no one can say with certainty that youre definitely cured.

All clear, or in remission which is another term you may have heard used, means theres no obvious sign of cancer at the moment.

If your breast cancer has spread to other parts of your body this will affect your prognosis. Secondary breast cancer can be treated, sometimes for many years, but not cured. Find out more about secondary breast cancer.

In order to be as clear as possible, your treatment team is more likely to talk about your chances of survival over a period of time or the possibility of remaining free of breast cancer in the future.

Tests To Determine The Need For Chemotherapy

If the cancer is early-stage and has certain characteristics, you may be eligible for a genomic test, which looks at specific genes in the cancer to predict how likely the cancer is to recur . If a cancer is not very likely to come back, you might not need chemotherapy. If the cancer is more likely to come back, you and your doctor might decide that chemotherapy is right for you. Oncotype DX, MammaPrint, and the Prosigna Breast Cancer Prognostic Gene Signature Assay are some examples of genomic tests. Learn more about breast cancer tests.

Less Common Types Of Invasive Breast Cancer

Treatment Strategies for Stage One Breast Cancer

There are some special types of breast cancer that are sub-types of invasive carcinoma. They are less common than the breast cancers named above and each typically make up fewer than 5% of all breast cancers. These are often named after features of the cancer cells, like the ways the cells are arranged.

Some of these may have a better prognosis than the more common IDC. These include:

  • Adenoid cystic carcinoma
  • Low-grade adenosquamous carcinoma
  • Medullary carcinoma

Some sub-types have the same or maybe worse prognoses than IDC. These include:

  • Metaplastic carcinoma
  • Micropapillary carcinoma
  • Mixed carcinoma

In general, all of these sub-types are still treated like IDC.

Treating Invasive Breast Cancer

Treatment of invasive breast cancer depends on how advanced the cancer is and other factors. Most women will have some type of surgery to remove the tumor. Depending on the type of breast cancer and how advanced it is, you might need other types of treatment as well, either before or after surgery, or sometimes both.

When Should I See My Healthcare Provider Regarding Invasive Ductal Carcinoma

If you notice any unusual changes in your breast tissue, schedule an appointment with your healthcare provider. If youre currently undergoing treatment for invasive ductal carcinoma, call your healthcare provider if you develop any concerning symptoms, such as high fever, chills, confusion, chest pain, shortness of breath , bone pain or abdominal pain.

What Is Stage Ii 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.

Stage 0 Breast Cancer

Breast Cancer

What is Stage 0 breast cancer?

Stage 0 breast cancer is when the cells that line the milk ducts have become cancerous. This type of cancer is called ductal carcinoma in situ , or non-invasive or pre-invasive breast cancer.

At this stage, the cancer has not spread to surrounding tissues. And while its considered non-invasive, its important to remember that it can still become invasive and spread beyond the milk ducts if it isnt treated.

What are the treatment options for Stage 0 breast cancer?

  • Surgery Breast surgery is often the first step at Stage 0. Depending on the size of the tumor, how fast the cancer appears to be growing and your personal preferences, there are two types of surgical options:
  • Lumpectomy A lumpectomy is a targeted surgery that removes the lump or tumor in question, and a small amount of normal tissue around it. This is commonly referred to as breast conservation surgery . In the United States, most women with Stage 0 breast cancer undergo a lumpectomy followed by radiation therapy.
  • Mastectomy If the cancer has spread throughout the ducts and affects a large part of the breast, doctors may recommend a mastectomy. With this surgery, the entire breast is removed and possibly some lymph nodes as well.
  • Radiation If BCS is done, radiation is almost always recommended after surgery. The goal of radiation is to get rid of any cancer cells lingering in your breast and prevent them from coming back.

    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
