What Are The Stages Of Melanoma

After Melanoma Has Been Diagnosed Tests May Be Done To Find Out If Cancer Cells Have Spread Within The Skin Or To Other Parts Of The Body

The 4 Stages of Melanoma: The Deadliest Form of Skin Cancer – Mayo Clinic

The process used to find out whether cancer has spread within the skin or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment.

For melanoma that is not likely to spread to other parts of the body or recur, more tests may not be needed. For melanoma that is likely to spread to other parts of the body or recur, the following tests and procedures may be done after surgery to remove the melanoma:

The results of these tests are viewed together with the results of the tumor biopsy to find out the stage of the melanoma.

Sentinel Lymph Node Biopsy

If melanoma spreads, it will usually begin spreading through channels in the skin to the nearest group of glands . Lymph nodes are part of the body’s immune system. They help remove unwanted bacteria and particles from the body and play a role in activating the immune system.

A sentinel lymph node biopsy is a test to determine whether microscopic amounts of melanoma have spread to your lymph nodes. It’s usually done by a specialist plastic surgeon, while you’re under general anaesthetic.

A combination of blue dye and a weak radioactive chemical is injected around your scar. This is usually done just before the wider area of skin is removed. The solution follows the same channels in the skin as any melanoma.

The first lymph node the dye and chemical reaches is known as the “sentinel” lymph node. The surgeon can locate and remove the sentinel node, leaving the others intact. The node is then examined for microscopic specks of melanoma .

If the sentinel lymph node is clear of melanoma, it’s extremely unlikely that any other lymph nodes are affected. This can be reassuring, because if melanoma reaches the lymph nodes, it’s more likely to spread elsewhere.

If the sentinel lymph node contains melanoma, there’s a risk that other lymph nodes in the same group will also contain melanoma.

Your surgeon should discuss the pros and cons of having a sentinel lymph node biopsy before you agree to having it.

What You Need To Know About Stages Of Melanoma

Those with basic knowledge of cancer know that once the presence of cancer is established, the next question is always, what stage? The stages of cancer are generally used to characterize how advanced the disease is what the prognosis and best melanoma treatment options are. By the time stage 4 metastatic melanoma status is reached, it is a bleak outlook for five year survival after diagnosis. Most cancer types have four or five stages and specific parameters of each type determine what stage it is considered to be in. Melanoma cancer has five stages.

Stage 0

The first stage of the melanoma stages is stage zero. Stage zero is characterized by a melanoma that has not penetrated beyond the epidermis, or top skin layer. Melanoma symptoms at this stage are little to none but can be identified if one is aware of what to look for. Because at stage zero the melanoma cells are isolated, there is a good prognosis that it will not spread any further if melanoma treatment by removal is started immediately. This is usually a quick outpatient surgery and usually doesnt need any more intervention post procedure.

What Does Melanoma Look Like

Melanoma is a type of cancer that begins in melanocytes . Below are photos of melanoma that formed on the skin. Melanoma can also start in the eye, the intestines, or other areas of the body with pigmented tissues.

Often the first sign of melanoma is a change in the shape, color, size, or feel of an existing mole. However, melanoma may also appear as a new mole. People should tell their doctor if they notice any changes on the skin. The only way to diagnose melanoma is to remove tissue and check it for cancer cells.

Thinking of “ABCDE” can help you remember what to look for:

  • Asymmetry: The shape of one half does not match the other half.
  • Border that is irregular: The edges are often ragged, notched, or blurred in outline. The pigment may spread into the surrounding skin.
  • Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen.
  • Diameter: There is a change in size, usually an increase. Melanomas can be tiny, but most are larger than the size of a pea .
  • Evolving: The mole has changed over the past few weeks or months.

Melanomas can vary greatly in how they look. Many show all of the ABCDE features. However, some may show changes or abnormal areas in only one or two of the ABCDE features.

What Is A Five

Staging Melanoma

Five-year survival rate refers to the average number of people with a particular disease or condition who are alive five years after being diagnosed.

Cancer experts based five-year survival rates for melanoma on information from a database called SEER, which stands for the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program.

Survival statistics from the SEER database are not based on AJCC melanoma staging. Instead, they’re based on if and how far the melanoma has spread:


The five-year survival rate for all three SEER stages combined is 93%.

The five-year survival rate for all three SEER stages combined is 93%.

What You Can Do

Check yourself: No matter your risk, examine your skin head-to-toe once a month to identify potential skin cancers early. Take note of existing moles or lesions that grow or change. Learn how to check your skin here.

When in doubt, check it out. Because melanoma can be so dangerous once it advances, follow your instincts and visit your doctor if you see a spot that just doesnt seem right.

Keep in mind that while important, monthly self-exams are not enough. See your dermatologist at least once a year for a professional skin exam.

If youve had a melanoma, follow up regularly with your doctor once treatment is complete. Stick to the schedule your doctor recommends so that you will find any recurrence as early as possible.

Treatments For Stage Ii Melanoma

As with stage I, stage II melanoma is typically treated with wide excision surgery, which cuts out the melanoma along with a margin of healthy surrounding skin. In the case of stage II melanoma, many doctors will recommend looking for cancer in nearby lymph nodes by performing a sentinel lymph node biopsy, which may necessitate further treatment if cancer cells are found.

What Is Stage Iii And Stage Iv Melanoma

Stage III and Stage IV melanoma is also sometimes called advanced melanoma, or secondary melanoma. This is when the melanoma has grown beyond the skin and has either spread to your lymphatic system that is, melanoma cells can be found in your lymph nodes or has spread beyond the regional lymph nodes to other parts of your body .

When the cancer spreads or metastasises to other parts of the body, away from the original site, the cells still have the characteristics of a melanoma even though they may now be growing somewhere else. The most common sites of melanoma metastases are in vital organs , bone, soft tissues and distant lymph nodes .

What Are Lymph Nodes

Improving Survival in Stage III Melanoma

Lymph nodes are small structures that filter substances and help fight infection. They are part of a network that runs throughout the body. Cancer that reaches the lymph nodes is concerning because cancer cells can easily spread to other parts of the body through this interconnected system.

Whether or not a melanoma spreads to one or more lymph nodes, it also may affect nearby skin. Such melanoma tumors are called satellite tumors. They’re defined as being within 2 centimeters of the original tumor and can be seen without a microscope.

Melanoma tumors also may spread to lymphatic channels, thin tubes that resemble blood capillaries, through which lymph fluid flows.

Factors Used For Staging Melanoma

To determine the stage of a melanoma, the lesion and some surrounding healthy tissue need to be surgically removed and analyzed using a microscope. Doctors use the melanomas thickness, measured in millimeters , and the other characteristics described in Diagnosis to help determine the diseases stage.

Doctors also use results from diagnostic tests to answer these questions about the stage of melanoma:

  • How thick or deep is the original melanoma, often called the primary melanoma or primary tumor?

  • Where is the melanoma located?

  • Has the melanoma spread to the lymph nodes? If so, where and how many?

  • Has the melanoma metastasized to other parts of the body? If so, where and how much?

The results are combined to determine the stage of melanoma for each person. The stages of melanoma include: stage 0 and stages I through IV . The stage provides a common way of describing the cancer, so doctors can work together to create the best treatment plan and understand a patient’s prognosis.

Stage : Melanoma In Situ

The earliest stage of melanoma is stage 0, also known as melanoma in situ or carcinoma in situ. In situ is a Latin phrase that means in position, and this diagnosis means that the cancer cells are present only in the epidermisthe bodys most superficial layer of skinand nowhere else.

This diagnosis has a very good prognosis, Noelani González, MD, an instructor of dermatology at the Mount Sinai Icahn School of Medicine in New York City, tells Health. People with localized melanomas who are treated quickly have a 5-year survival rate of 97%meaning they are, on average, about 97% as likely to still be alive in five years as people who dont have these cancers.

Treatment for this stage cancer involves a wide excision surgery, where the affected skin is cut away and the wound is stitched and bandaged. The skin will be removed with margins, explains Dr. González. That means that some normal skin will also be removed around the edges to make sure there arent any cancer cells left over.

The removed skin is then looked at under a microscope to ensure that all of the cancer was removed with clean margins, says Dr. González. Because stage 0 cancer has not spread to any other tissues or organs, no further treatment is required.

The Abcdes Of Melanoma

The first five letters of the alphabet are a guide to help you recognize the warning signs of melanoma.

A is for Asymmetry. Most melanomas are asymmetrical. If you draw a line through the middle of the lesion, the two halves dont match, so it looks different from a round to oval and symmetrical common mole.

B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.

C is for Color. Multiple colors are a warning sign. While benign moles are usually a single shade of brown, a melanoma may have different shades of brown, tan or black. As it grows, the colors red, white or blue may also appear.

D is for Diameter or Dark. While its ideal to detect a melanoma when it is small, its a warning sign if a lesion is the size of a pencil eraser or larger. Some experts say it is also important to look for any lesion, no matter what size, that is darker than others. Rare, amelanotic melanomas are colorless.

E is for Evolving. Any change in size, shape, color or elevation of a spot on your skin, or any new symptom in it, such as bleeding, itching or crusting, may be a warning sign of melanoma.

If you notice these warning signs, or anything NEW, CHANGING or UNUSUAL on your skin see a dermatologist promptly.

What You Need To Know About Early Detection

Melanoma Symptoms, Stages &  Metastatic Melanoma Symptoms

Finding melanoma at an early stage is crucial early detection can vastly increase your chances for cure.

Look for anything new,changing or unusual on both sun-exposed and sun-protected areas of the body. Melanomas commonly appear on the legs of women, and the number one place they develop on men is the trunk. Keep in mind, though, that melanomas can arise anywhere on the skin, even in areas where the sun doesnt shine.

Most moles, brown spots and growths on the skin are harmless but not always. The ABCDEs and the Ugly Duckling sign can help you detect melanoma.

Early detection makes a difference

99%5-year survival rate for patients in the U.S. whose melanoma is detected early. The survival rate drops to 66% if the disease reaches the lymph nodes and27% if it spreads to distant organs.

Clinical Staging For Malignant Melanoma

  • Used for staging of melanomas which have spread beyond the primary tumor or which do not have adequate tissue for pathological examination.
  • Clinical staging includes results of tests and examinations as well as pathological findings.
  • Clinical staging parallels Summary Staging
  • Stage I Localizedâwithout metastases to distant or regional nodes (allows localized disease up to 5 cm. from initial tumor within primary lymphatic drainage area
  • Stage II Regionalizedâinvolvement of regional nodes
  • Stage III Disseminatedâvisceral or lymphatic metastases or multiple cutaneous or subsequent metastases
  • Reference to stage in melanoma cannot be assumed to be clinical, Clark’s, or Breslow’s unless specifically identified as such.
  • Lymph Node Dissection Or Completion Lymphadenectomy

    An operation to remove the remaining lymph nodes in the group is known as a completion lymph node dissection or completion lymphadenectomy. Again, you should discuss the pros and cons of the procedure with your surgeon.

    Stages Of Melanoma Skin Cancer

    Staging describes or classifies a cancer based on how much cancer there is in the body and where it is when first diagnosed. This is often called the extent of cancer. Information from tests is used to find out the size of the tumour, which parts of the skin have cancer, whether the cancer has spread from where it first started and where the cancer has spread. Your healthcare team uses the stage to plan treatment and estimate the outcome .

    The most common staging system for melanoma skin cancer is the TNM system. For melanoma skin cancer there are 5 stages stage 0 followed by stages 1 to 4. Often the stages 1 to 4 are written as the Roman numerals I, II, III and IV. Generally, the higher the stage number, the more the cancer has spread. Talk to your doctor if you have questions about staging.

    When describing the stage, doctors often use the words early stage, locoregional or metastatic.

    Early stage means that the cancer is only in where it started and has not spread to other parts of the body. It includes stage 0, stage 1A, stage 1B, stage 2A, stage 2B and stage 2C melanoma skin cancers.

    Locoregional means the cancer has spread to nearby lymph nodes, or it has spread to nearby areas of skin or lymph vessels. It includes stage 3 melanoma skin cancer.

    Metastatic means that the cancer is in a part of the body farther from where it started. It includes stage 4 melanoma skin cancer.

    Advice for patients with stage 3 melanoma

    Early melanomas

    Stage 0 and I are localized, meaning they have not spread.

    • Stage 0: Melanoma is localized in the outermost layer of skin and has not advanced deeper. This noninvasive stage is also called melanoma in situ.
    • Stage I: The cancer is smaller than 1 mm in Breslow depth, and may or may not be ulcerated. It is localized but invasive, meaning that it has penetrated beneath the top layer into the next layer of skin. Invasive tumors considered stage IA are classified as early and thin if they are not ulcerated and measure less than 0.8 mm.

    Find out about treatment options for early melanomas.

    Intermediate or high-risk melanomas

    Localized but larger tumors may have other traits such as ulceration that put them at high risk of spreading.

    • Stage II: Intermediate, high-risk melanomas are tumors deeper than 1 mm that may or may not be ulcerated. Although they are not yet known to have advanced beyond the primary tumor, the risk of spreading is high, and physicians may recommend a sentinel lymph node biopsy to verify whether melanoma cells have spread to the local lymph nodes. Thicker melanomas, greater than 4.0 mm, have a very high risk of spreading, and any ulceration can move the disease into a higher subcategory of stage II. Because of that risk, the doctor may recommend more aggressive treatment.

    Learn More About Your Lymph Nodes And Lymphatic System

    Lymph nodes are found throughout the body and are part of the lymphatic system.

    The lymphatic system contains a series of lymph vessels that carry the lymph fluid through the nodes back to the bloodstream.

    Lymph nodes contain white blood cells that help fight infection and diseases, such as cancer.

    The number of lymph nodes you have is different for each person.

    For example, there can be between 15 to 30 nodes in an armpit. Lymph nodes also vary in size from a pinpoint to the size of a baked bean.

    Lymph nodes can swell and become tender when you have an infection. If you develop a swollen lymph node, get it checked by your doctor.

    Sometimes, cancer cells spread into the lymph nodes from cancer in another part of the body. It is also possible for cancer to start in a lymph node. This type of cancer is called lymphoma.
