What Are The Melanoma Stages And What Do They Mean
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.

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.

Should I Have Routine Skin Cancer Screenings
While many routine cancer screenings, such as colonoscopies and mammograms, are recommended when a person reaches a certain age, there are no widely adopted age standards for dermatological screenings. Most primary physicians will perform a quick skin check at a routine physical, but we recommend that those with a higher risk for skin cancer have a thorough skin screening by a dermatologist at least once a year. This includes anyone with:
- A family history of melanoma in two or more blood relatives
- Multiple atypical moles
- Numerous actinic keratoses
- An organ transplant
Reducing Risk With Skin Evaluations
Most skin cancers can be successfully treated when detected early. Thats why our dermatologists encourage patients to have annual skin checks, perform regular self-examinations, and protect their skin with sunscreen and wear protective clothing.
While all people can get skin cancer, some people are at greater risk, and should be evaluated more regularly:
- People with fair skin
- People with a history of sunburns, or a personal or family history of skin cancer
- People who have a large number of moles or precancerous skin lesions, called actinic keratosis
- Organ transplant recipients

Looking For Signs Of Skin Cancer
Non melanoma skin cancers;tend to develop most often on skin that’s exposed to the sun.
To spot skin cancers early it helps to know how your skin normally looks. That way, you’ll notice any changes more easily.
To look at areas you cant see easily, you could try using a hand held mirror and reflect your skin onto another mirror. Or you could get your partner or a;friend to look. This is very important if you’re regularly outside in the sun for work or leisure.;
You can;take;a photo;of anything that doesn’t look quite right. If you can it’s a good idea to put a ruler or tape measure next to the abnormal area;when you take the photo. This;gives you a more accurate idea about its size and can help you tell if it’s changing. You can then show these pictures to your doctor.;
What Skin Cancer Looks Like
Skin cancer appears on the body in many different ways. It can look like a:
Changing mole or mole that looks different from your others
Non-healing sore or sore that heals and returns
Brown or black streak under a nail
It can also show up in other ways.
To find skin cancer on your body, you dont have to remember a long list. Dermatologists sum it up this way. Its time to see a dermatologist if you notice a spot on your skin that:
Differs from the others
To make it easy for you to check your skin, the AAD created the Body Mole Map. Youll find everything you need to know on a single page. Illustrations show you how to examine your skin and what to look for. Theres even place to record what your spots look like. Youll find this page, which you can print, at Body Mole Map.

What Are The Warning Signs Of Melanoma
The first five letters of the alphabet are a guide to help you recognise 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 don’t 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 Colour. Multiple colours 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 colours red, white or blue may also appear.
D is for Diameter or Dark. While it’s ideal to detect a melanoma when it is small, it’s 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 colourless.
E is for Evolving. Any change in size, shape, colour 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.
The appearance of melanoma varies dramatically from person to person, but the first sign is often a tiny new spot or a change in the shape or texture of an existing mole.
From 2010 to 2014, 2,198 men were diagnosed. That number jumped to 2,946 between 2015 and 2019.
How Do I Know If I Have Skin Cancer
All potentially cancerous skin growths must be biopsied to confirm a cancer diagnosis. Depending on the suspected type of skin cancer, the biopsy techniques vary slightly but crucially.
Any potential melanoma requires a surgical biopsy, in which the entire growth is removed with a scalpel if possible. A pathologist then studies the sample under a microscope to determine whether cancer cells are present.
If;melanoma;;is diagnosed, other tests may be ordered to assess the degree of cancer spread . They include:
- Imaging. Your doctor will order one or more tests to look for metastasis. They include CT scan, MRI, PET scan, bone scan, and chest X-ray.
- Other biopsies. Using a variety of techniques, your doctor may want to get tissue samples from lymph nodes.
Skin growths that are most likely basal cell carcinoma, squamous cell carcinoma, or other forms of non-melanoma can be biopsied in various ways. Part or all of the growth can be taken with a scalpel for examination under a microscope.

How Is Cancer On The Scalp Treated
Potential treatments for skin cancer on your scalp include:
- Surgery. Your doctor will remove the cancerous growth and some of the skin around it, to make sure that they removed all the cancer cells. This is usually the first treatment for melanoma. After surgery, you may also need reconstructive surgery, such as a skin graft.
- Mohs surgery. This type of surgery is used for large, recurring, or hard-to-treat skin cancer. Its used to save as much skin as possible. In Mohs surgery, your doctor will remove the growth layer by layer, examining each one under a microscope, until there are no cancer cells left.
- Radiation. This may be used as a first treatment or after surgery, to kill remaining cancer cells.
- Chemotherapy. If your skin cancer is only on the top layer of skin, you might be able to use a chemotherapy lotion to treat it. If your cancer has spread, you might need traditional chemotherapy.
- Freezing. Used for cancer that doesnt go deep into your skin.
- . Youll take medications that will make cancer cells sensitive to light. Then your doctor will use lasers to kill the cells.
The outlook for skin cancer on your scalp depends on the specific type of skin cancer:
Basal Cell Carcinoma Pictures
Basal cell carcinoma usually appears in areas of the skin previously exposed to high levels of UV radiation such as the head, neck, ears and the back of the arms and hands. It is common in exposed skin of outdoor workers or people who have used sun tanning beds in the past.
As the basal cell carcinoma pictures below indicate, this type of skin cancer usually shows as a fleshy coloured bump that does not disappear over time and tends to grow slowly in size, eventually breaking down and ulcerating.
Below are pictures of skin cancer on the neck, face and trunk;. These images show common areas where;basal cell carcinoma;develops, but it can develop anywhere.

Who Is Most At Risk For Skin Cancer
Although anyone can develop skin cancer, those that are most at risk for skin cancer are people who:
- Have had an organ transplant
- Tan or use tanning beds
- Get easily sunburned
- Have fair or freckled skin
- Have a family history of skin cancer
- Have blue eyes
- Take medications that suppress/weaken the immune system
People who work or spend more time outdoors have an increased risk for skin cancer, especially those in sunny climates. People with darker skin are still able to get skin cancer, but the risk is substantially lower. Organ transplant patients are up to 100 times more likely to develop squamous cell carcinoma skin cancer when compared to the general population, largely because they take medications that suppress their immune systems.
Risk factors unique to melanoma include a history of severe sunburns and an abundance of large and irregular moles.
Am I At Risk For Skin Cancer
Anyone can get skin cancer, regardless of skin color. However, some factors increase your risk, including:
- A personal history of skin cancer
- Skin that burns, freckles, reddens easily, or becomes painful in the sun
- Blue or green eyes
- A history of indoor tanning
- Certain types and a large number of moles
- A family history of skin cancer
- Having had a lung, heart, kidney, pancreas or liver transplant

How Is Skin Cancer Treated
Treatment depends upon the stage of the cancer. Some types of treatment include the following:
- Mohs micrographic surgery uses a scalpel to remove the tumor and thin layer of surrounding tissue.
- Excisional surgery involves a surgeon removing the tumor and some predetermined amount of surrounding healthy skin to be sure all cancer has been removed.
- Electrosurgery uses heat to burn the tumor and some surrounding area.
- Cryosurgery involves freezing the tumor and may require multiple treatments.
Radiation therapy or topical therapy can be used for cancers in places that are hard to reach with surgery or for patients who are not able to have surgery.
Different Types Of Cancer Start In The Skin
Skin cancer may form in basal cells or squamous cells. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer. They are also called nonmelanoma skin cancer. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.
Melanoma is less common than basal cell carcinoma or squamous cell carcinoma. It is more likely to invade nearby tissues and spread to other parts of the body.
This summary is about basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis. See the following PDQ summaries for information on melanoma and other kinds of cancer that affect the skin:

Causes Of Skin Cancer
One of the main causes of skin cancer is being exposed to UV rays. UV rays are invisible, and are produced by the sun, and tanning equipment.
UV rays cause skin cancer by creating changes in the cells of your skin. In some cases, the UV rays cause direct damage to your cells. Tans and sunburns, for example, are both signs that UV rays have damaged your skin. In other cases, UV rays cause skin cancer indirectly, by weakening the immune system.
Many studies on skin cancer show that people who have suffered many severe sunburns in childhood are at greater risk of developing skin cancer. Family history, some chemical exposures, and immune dysfunction conditions can also create a greater risk of developing skin cancer.
What Do The Results Mean
If a mole or other mark on your skin looks like it might be a sign of cancer, your provider will probably order another test, called a skin biopsy, to make a diagnosis. A skin biopsy is a procedure that removes a small sample of skin for testing. The skin sample is looked at under a microscope to check for cancer cells. If you are diagnosed with skin cancer, you can begin treatment. Finding and treating cancer early may help prevent the disease from spreading.

When You’re Diagnosed With Skin Cancer
Written by Dr. Alison Durham, U-M Rogel Cancer Center Skin Cancer Program.
At some point in their life, one in five Americans will develop some type of skin cancer. The most common types are:
- basal cell carcinoma
- squamous cell carcinoma
You can limit your lifetime risk of developing skin cancer by using sun safety and UV prevention tactics. Because early detection is important for every type of skin cancer, pay attention to changes in your skin and consult your doctor or dermatologist for anything suspicious.
The first step in treating skin cancer is proper diagnosis. This requires your doctor to remove a small tissue sample from the suspected site. When done at Michigan Medicine, a specially trained dermatopathologist examines the biopsy to determine if cancer is present and if so what type.
When your skin cancer is biopsy-confirmed, your dermatologist will recommend the treatment options best suited to your skin cancer type based on the location, size, and features noted on the biopsy specimen. Most skin cancer treatment is done on an outpatient basis, typically by one of the following three methods:

Should I Have A Shave Or Excisional Biopsy For A Mole That Might Be Cancerous
Your doctor will decide which type of biopsy is best for your mole. If there is no reason to suspect melanoma, a shave biopsy that removes just a thin slice of the skin is usually appropriate for a diagnosis. However, if there is a risk of malignancy, the entire growth may be removed, or at least part of it .

Staging For Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin Depends On Where The Cancer Formed
Staging for basal cell carcinoma and squamous cell carcinoma of the eyelid is different from staging for basal cell carcinoma and squamous cell carcinoma found on other areas of the head or neck. There is no staging system for basal cell carcinoma or squamous cell carcinoma that is not found on the head or neck.
Surgery to remove the primary tumor and abnormal lymph nodes is done so that tissue samples can be studied under a microscope. This is called pathologic staging and the findings are used for staging as described below. If staging is done before surgery to remove the tumor, it is called clinical staging. The clinical stage may be different from the pathologic stage.
