A Stands For Asymmetry:
Asymmetry means the mole is not symmetrical and when cut into half the two sides do not match each other. Normal moles or benign forms are symmetrical. When checking the recent freckle, imagine a line dividing the mole into two halves and assuming that, check for symmetry. For asymmetrical moles be sure to see your dermatologist as soon as possible.
Less Common Types Of Skin Cancer
Kaposi sarcoma
This is a rare form of skin cancer that develops in the skins blood vessels and causes red or purple patches. It often attacks people with weakened immune systems, such as individuals with AIDS, or in people taking medications that suppress their immune system, such as patients whove received organ transplants.
Merkel cell carcinoma
Merkel cell carcinoma causes firm, shiny nodules that occur on the surface or just beneath the skin and in hair follicles. Merkel cell carcinoma most often appears on the head, neck and torso.
Sebaceous gland carcinoma
This rare but aggressive cancer develops in the skins oil glands. Sebaceous gland carcinomas which usually appear as hard, painless nodules can develop anywhere, but frequently occur on the eyelid, where they can be mistaken for other eyelid problems.
Squamous Cell Carcinoma Early Stages
The second most common form of cancer in the skin is squamous cell carcinoma. At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas. Without proper treatment, squamous cell carcinoma can become life-threatening once it has spread and damaged healthy tissue and organs.

Are There Other Non
There are other types of non-melanoma skin cancers that are rare. These are Merkel Cell carcinoma, Kaposys sarcoma and cutaneous T cell lymphoma. These tumors biological behavior and therapeutics are different from the other more common types mentioned before. Lastly, metastatic tumors from other cancers can appear in the skin. These are not considered skin cancer.
What You Need To Know About Early Detection
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.

What Do The Early Stages Of Skin Cancer Look Like
Early stage skin cancer may resemble a small spot or discolored blemish significantly smaller than the size of a fingernail. It may be reddish or brown, though sometimes white with flaking skin cells surrounded by a small blotch of darker skin.
If you have concerns about the recent appearance of unusual spots on your skin, schedule an appointment right away with a board-certified dermatologist.
Skin cancer is the abnormal growth of skin cells. Skin cancer develops when mutations occur in the DNA of skin cells. The mutations can quickly cause cells to grow out of control and turn into a mass of cancer cells, which then attack healthy cells.
The most common cause of skin cancer is prolonged overexposure to the sun, sometimes over a period of years, but skin cancer can also develop on areas of your skin not exposed to sunlight.
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and melanoma. Other, rare forms of skin cancer also exist.
Skin cancer starts in the epidermis, which is the top layer of your skin. This top layer contains three main types of cells:
Research has shown that patients with skin of color are less likely to survive melanoma. Late detection is one of the critical reasons for this higher mortality rate. On average, 2 people die of skin cancer in the United States every hour, reports the Skin Cancer Foundation.
A Sore That Doesnt Heal
Many skin cancers are first dismissed as being due to a bug bite, minor injury, or irritation, but become more obvious when they donât go away over time. If you notice a sore on your skin that refuses to heal, even if it seems to be healing but then reappears, talk to your healthcare provider. In general, any skin change that hasnât resolved on its own over a period of two weeks should be evaluated.

What Does Skin Cancer Look Like On Your Face
As you examine your skin for early signs of skin cancer on your face, you should be checking your whole head, as well as your neck. These are the most common locations for skin cancer cases because they get the most sun exposure year-round. If you find a new or changing spot on your skin, use the ABCDE method to look for:
- Asymmetry: If you drew a line through the middle of the spot, would the two halves match up?
- Border: Are the edges of the spot irregular? Look for a scalloped, blurred, or notched edge.
- Color: A healthy blemish or mole should be uniform in color. Varying shades of brown, red, white, blue, black, tan, or pink are cause for concern.
- Diameter: Is the spot larger than 6mm? Skin cancer spots tend to be larger in diameter than a pencil eraser, although they can be smaller.
- Evolving: If the size, shape, or color of a spot changes or it starts to bleed or scab, there is potential for it to be cancerous.
Basal Cell Carcinoma Symptoms
Basal cell carcinoma, the most common form of skin cancer, is sneaky because it doesnt always appear super alarming. For many, it can look like an ordinary pimple or even a harmless patch of eczema, typically on the face, head, or neck.
When what appears to be a common skin condition doesnt go away, keeps bleeding, breaking open, or getting irritated, thats your clue that something more serious may be lurking, and its time to head to the dermatologist.

What Does Early Skin Cancer Look Like
It can be challenging to tell if a skin change is unimportant or, in fact, is a sign of developing skin cancer. Skin cancer is not uncommon, as one in five Americans will develop skin cancer before age 70. Learning to spot the warning signs is vital. When identified early, skin cancer is highly curable. Do you know what to look for or when to seek medical advice?
The Abcde Rule For Melanoma
The ABCDE rule is a useful guide to the common signs of melanoma:
- Asymmetry: For example, one half of a mole or birthmark does not match the other.
- Border: The edges of the spot are irregular or blurred.
- Color: The color varies and may include different shades of brown or black, or even patches of pink, red, white or blue.
- Diameter: The spot is larger than the size of pencil eraser.
- Evolving: The spot is changing in size, shape or color.
Early recognition of possible melanoma skin cancer symptoms can result in earlier diagnosis, as well as more treatment options and a higher likelihood of cure.

Symptoms Of Skin Cancer: Squamous Cell Carcinoma
The second most common type of skin cancer. Derived from the squamous cell of the skin that form the epidermis, in the USA about 200,000 new cases are diagnosed every year and about 1,900 deaths are attributed to it. Also of slow growth rate, these tumors invade and metastasize if left untreated. They have similar distribution as BCC although they tend to be more frequent than BCC in arms and hands.
SCC tend to manifest as inflamed, reddened, scaly or crusty growth, sore or tender. Occasionally they can ulcerate, bleed or crust, not healing over time. They can take the shape of a wart, a reddened patch or an ulcer, with crust or bleeding. Occasionally they can present as a lump with central depression than bleeds.
SCC have an association with prolonged exposure to UV radiation. Additionally, they have an association with radiotherapy used to treat other cancers, infection with human papilloma virus, chemical toxins, immunosuppressive medications and low antioxidant diets.

How Is Skin Cancer Diagnosed
First, your dermatologist may ask you if you have noticed any changes in any existing moles, freckles or other skin spots or if youve noticed any new skin growths. Next, your dermatologist will examine all of your skin, including your scalp, ears, palms of your hands, soles of your feet, between your toes, around your genitals and between your buttocks.
If a skin lesion is suspicious, a biopsy may be performed. In a biopsy, a sample of tissue is removed and sent to a laboratory to be examined under a microscope by a pathologist. Your dermatologist will tell you if your skin lesion is skin cancer, what type you have and discuss treatment options.

What Are The Symptoms Of Skin Cancer
Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesnt heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma.
A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesnt heal, or a change in a mole.external icon Not all skin cancers look the same.
For melanoma specifically, a simple way to remember the warning signs is to remember the A-B-C-D-Es of melanoma
- A stands for asymmetrical. Does the mole or spot have an irregular shape with two parts that look very different?
- B stands for border. Is the border irregular or jagged?
- C is for color. Is the color uneven?
- D is for diameter. Is the mole or spot larger than the size of a pea?
- E is for evolving. Has the mole or spot changed during the past few weeks or months?

Does Skin Cancer Affect People With Skin Of Color
People of all skin tones can develop skin cancer. If you are a person of color, you may be less likely to get skin cancer because you have more of the brown pigment, melanin, in your skin.
Although less prevalent than in nonwhite people, when skin cancer does develop in people of color, its often found late and has a worse prognosis. If youre Hispanic, the incidence of melanoma has risen by 20% in the past two decades. If youre Black and develop melanoma, your five-year survival rate is 25% lower than it is for white people . Part of the reason may be that it develops in less typical, less sun-exposed areas and its often in late-stage when diagnosed.

Possible Signs And Symptoms Of Melanoma
The most important warning sign of melanoma is a new spot on the skin or a spot that is changing in size, shape, or color.
Another important sign is a spot that looks different from all of the other spots on your skin .
If you have one of these warning signs, have your skin checked by a doctor.
The ABCDE rule is another guide to the usual signs of melanoma. Be on the lookout and tell your doctor about spots that have any of the following features:
- A is for Asymmetry: One half of a mole or birthmark does not match the other.
- B is for Border:The edges are irregular, ragged, notched, or blurred.
- C is for Color:The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white, or blue.
- D is for Diameter:The spot is larger than 6 millimeters across , although melanomas can sometimes be smaller than this.
- E is for Evolving: The mole is changing in size, shape, or color.
Some melanomas dont fit these rules. Its important to tell your doctor about any changes or new spots on the skin, or growths that look different from the rest of your moles.
Other warning signs are:
- A sore that doesnt heal
- Spread of pigment from the border of a spot into surrounding skin
- Redness or a new swelling beyond the border of the mole
- Change in sensation, such as itchiness, tenderness, or pain
- Change in the surface of a mole scaliness, oozing, bleeding, or the appearance of a lump or bump

Basal Cell Skin Cancer Warning Signs
Basal cell cancer tends to develop on parts of the body that get a lot of sun exposure, like the face, head, and neck, but they can appear anywhere.
Some are flat and look a lot like normal skin. Others have more distinctive characteristics, says the American Cancer Society , including:
- Flat, firm, pale, or yellow areas that resemble a scar
- Raised, reddish patches of skin that might be itchy or irritated
- Small bumps that might be pink, red, pearly translucent, or shiny, possibly with areas of blue, brown, or black
- Pink growths with slightly raised edges and an indentation in the center tiny blood vessels might run through it like the spokes of a wheel
- Open sores, possibly with oozing or crusted areas, that dont heal or that go through cycles of healing and bleeding
- Delicate areas that bleed easily. For instance, having a sore or cut from shaving that lingers longer than one week.
These slow-growing skin cancers can be easy to ignore unless they become big and begin to itch, bleed, or even hurt, according to the ACS.

Are All Moles Cancerous
Most moles are not cancerous. Some moles are present at birth, others develop up to about age 40. Most adults have between 10 and 40 moles.
In rare cases, a mole can turn into melanoma. If you have more than 50 moles, you have an increased chance of developing melanoma.
A note from Cleveland Clinic
Your skin is the largest organ in your body. It needs as much attention as any other health concern. What may seem like an innocent cosmetic imperfection, may not be. Performing regular skin self-checks is important for everyone and is especially important if you are a person at increased risk of skin cancer. Skin cancer is also color-blind. If you are a person of color, skin cancer can happen to you. Check your skin every month for any changes in skin spots or any new skin growths. Consider taking skin selfies so you can easily see if spots change over time. If youre a person of color, be sure to check areas more prone to cancer development, such as the palms of your hands, soles of your feet, between your toes, your genital area and under your nails. Takes steps to protect your skin. Always wear sunscreen with SPF of at least 30 every day of the year. Wear UV-A/UV-B protective sunglasses, wide-brimmed hats and long-sleeve shirts and pants. See your dermatologist at least once a year for a professional skin check.

The Five Stages Of Skin Cancer
Cancer in the skin thats at high risk for spreading shares features with basal cell carcinoma and squamous cell carcinoma. Some of these features are:
- Not less than 2 mm in thickness
- Has spread into the inner layers of the skin
- Has invaded skin nerves
Stage 0
In the earliest stage, cancer is only present in the upper layer of the skin. You may notice the appearance of blood vessels or a dent in the center of the skin growth. There are no traces of malignant cells beyond this layer.
Stage 1
At stage 1, cancer has not spread to muscles, bone, and other organs. It measures roughly 4/5 of an inch. Theres a possibility that it may have spread into the inner layer of the skin.
Stage 2
In this stage, cancer has become larger than 4/5 of an inch. Cancer still has not spread to muscles, bone, and other organs.
Stage 3
At stage 3, the cancer is still larger than 4/5 of an inch. Facial bones or a nearby lymph node may have been affected, but other organs remain safe. It may also spread to areas below the skin, such as into muscle, bone, and cartilage but not far from the original site.
Stage 4
Cancer can now be of any size and has likely spread into lymph nodes, bones, cartilage, muscle, or other organs. Distant organs such as the brain or lungs may also be affected. In rare cases, this stage might cause death when allowed to grow and become more invasive.
