How Does The Doctor Know I Have Skin Cancer
Basal and squamous skin cancer may look like:
- Flat, firm, pale or yellow areas that look a lot like a scar
- Raised reddish patches that might itch
- Rough or scaly red patches, which might crust or bleed
- Small, pink or red, shiny, pearly bumps, which might have blue, brown, or black areas
- Pink growths or lumps with raised edges and a lower center
- Open sores that dont heal, or that heal and then come back
- Wart-like growths
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.

Will I Get Skin Cancer If I Get Sunburn
Even a single sunburn can increase a persons risk of skin cancer. This is because when the skin absorbs ultraviolet radiation from sunlight, it can damage the genetic material in skin cells. In the short term, this damage can cause sunburns. In the long term, it builds up and raises the risk of skin cancer.

Skin Cancer Diagnosis Always Requires A Skin Biopsy
When you see a dermatologist because youve found a spot that might be skin cancer, your dermatologist will examine the spot.
If the spot looks like it could be a skin cancer, your dermatologist will remove it all or part of it. This can easily be done during your appointment. The procedure that your dermatologist uses to remove the spot is called a skin biopsy.
Having a skin biopsy is essential. Its the only way to know whether you have skin cancer. Theres no other way to know for sure.
What your dermatologist removes will be looked at under a microscope. The doctor who examines the removed skin will look for cancer cells. If cancer cells are found, your biopsy report will tell you what type of skin cancer cells were found. When cancer cells arent found, your biopsy report will explain what was seen under the microscope.
Should I Use A Skin Cancer Detection App
Anything that reminds you to look for signs of skin cancer is a good thing. However, some smartphone apps claim to be able to assess certain skin changes and inform individuals whether such changes warrant a visit to a dermatologist for further analysis.
Thus far, the accuracy of these is not high enough and relying solely on an app, rather than on your own observations and visits to a doctor, you could put yourself at risk by delaying a visit to the doctor when one is warranted. In one recent study, the most accurate skin cancer detection app missed almost 30% of melanomas, diagnosing them as low-risk lesions.
However, these apps are evolving, and one day they could become part of the arsenal to help detect skin cancer. Smartphones can be useful in terms of telemedicine. For instance, in locations where dermatologists may not be readily available, a local physician can send a photo of a suspicious mole to a dermatologist and based on visual inspection and communication with that physician, determine what steps to take next.

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.
Melanoma Can Be Tricky
Identifying a potential skin cancer is not easy, and not all melanomas follow the rules. Melanomas come in many forms and may display none of the typical warning signs.
Its also important to note that about 20 to 30 percent of melanomas develop in existing moles, while 70 to 80 percent arise on seemingly normal skin.
Amelanotic melanomas are missing the dark pigment melanin that gives most moles their color. Amelanotic melanomas may be pinkish, reddish, white, the color of your skin or even clear and colorless, making them difficult to recognize.
Acral lentiginous melanoma, the most common form of melanoma found in people of color, often appears in hard-to-spot places, including under the fingernails or toenails, on the palms of the hands or soles of the feet.
The takeaway: Be watchful for any new mole or freckle that arises on your skin, a sore or spot that does not heal, any existing mole that starts changing or any spot, mole or lesion that looks unusual.
Acral lentiginous melanoma is the most common melanoma found in people of color.

Skin Cancer Can Look Like Many Things Therefore People Can Go Long Periods Of Time Without Recognizing That They Have A Skin Cancer Says Dr Steven Musick Md A Board Certified Dermatologist Who Runs Musick Dermatology Llc In Swansea Il Which Provides State
Not only can skin cancer mimic many benign conditions such as pimples and skin barnacles, but a tumor can develop in areas that are difficult to inspect or that are not considered during a persons self-skin exam.
For example, it would be difficult for one to examine their scalp unless theyre bald. Inside the ears is another hard-to-visualize location.
And then there are areas that people wouldnt think to check, such as between their butt cheeks, inside their belly button, between their toes, the soles of their feet and even the pupils of their eyes.
Yes, melanoma can grow in the pupils and go unnoticed for long periods of time.
Melanoma, along with squamous cell carcinoma, can also pop up internally, including within the genitals, mouth, nose and lungs.
Another factor that influences how long a person can have skin cancer and not know it is where they live.
If they live in a Third, and especially Fourth, World nation, they can have a basal cell carcinoma that goes undiagnosed for many years due to lack of skin cancer awareness campaigns and adequate skin cancer screenings.
However, this type of tumor will continue progressing, though very slowly it wont stop growing just because its untreated.
How To Spot Skin Cancer
Skin cancer is by far the most common type of cancer. If you know what to look for, you can spot warning signs of skin cancer early. Finding it early, when its small and has not spread, makes skin cancer much easier to treat.
Some doctors and other health care professionals include skin exams as part of routine health check-ups. Many doctors also recommend that you check your own skin about once a month. Look at your skin in a well-lit room in front of a full-length mirror. Use a hand-held mirror to look at areas that are hard to see.
Use the ABCDE rule to look for some of the common signs of melanoma, one of the deadliest forms of skin cancer:
AsymmetryOne part of a mole or birthmark doesnt match the other.
BorderThe edges are irregular, ragged, notched, or blurred.
ColorThe color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue.
DiameterThe spot is larger than ¼ inch across about the size of a pencil eraser although melanomas can sometimes be smaller than this.
EvolvingThe mole is changing in size, shape, or color.
Basal and squamous cell skin cancers are more common than melanomas, but they are usually very treatable.
Both basal cell carcinomas and squamous cell carcinomas, or cancers, usually grow on parts of the body that get the most sun, such as the face, head, and neck. But they can show up anywhere.

Where Does Skin Cancer Develop
Skin cancer is most commonly seen in sun-exposed areas of your skin your face , ears, neck, arms, chest, upper back, hands and legs. However, it can also develop in less sun-exposed and more hidden areas of skin, including between your toes, under your fingernails, on the palms of your hands, soles of your feet and in your genital area.
Melanoma Skin Cancer Symptoms
Melanoma, the more dangerous type of skin cancer, can appear on the skin either in the form of a new spot or a mole that suddenly changes in appearance. While it can be difficult to tell the difference between a cancerous and non-cancerous mole at first glance, normal moles are often small, even in color, and consistent.
Dermatologists can separate cancerous moles from normal blemishes on the skin using a method called the ABCDE test. Learning the ABCDEs can help you to pinpoint the early signs of dangerous tumors.
ABCDE stands for:
- A: Asymmetrical: A standard mole is small and circular while a melanoma lesion looks strange, like a splotch of paint.
- B: Border: Non-cancerous moles have even borders, while melanoma lesions evolve over time, giving them outlines that are hard to define. It might look as though the color of the mole is seeping into your skin.
- C: Color: If the bump on your skin features multiple shades, this could be a warning sign of melanoma. Standard moles are usually all one color.
- D: Diameter: If something doesnt seem right about your mole, you might want to measure it. Lesions caused by melanoma are usually more than 6 millimeters in diameter.
- E: Evolution: A healthy mole doesnt change over time, but a melanoma lesion evolves. Thats why its so important to have regular skin checks with your doctor and perform them yourself at home.

How Can I Detect Skin Cancer
The first answer is to simply look at your skin. Because you see your skin every day, you are detector number one. By knowing what is normal for your skin, and then thoroughly inspecting it on a regular usually monthly basis, many skin cancers can be self- detected.
When examining your skin, take note of all existing spots, moles and freckles on your skin, so that youll know when changes occur or a new one appears. You can track these easily with this body mole map from the American Academy of Dermatology. Stand in front of mirror and examine your front and back, head to toe. Bend your elbows and look carefully at your forearms, palms and the back of your upper arms. Use a hand mirror to check the back of your neck, scalp, buttocks and other hard-to-see places. Dont forget the bottoms of your feet and between your toes.
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.

How Long Should I Use Efudex Cream
When you are handed your tube of Efudex, also known as fluorouracil, the label will display your dermatologists instructions. They, too, are straightforward and printed according to your doctors recommendations. You may have been told to apply a thin layer twice a day for 4 weeks. In some cases, patients might be instructed to apply cream once daily for 6-8 weeks. This, unfortunately, is where things begin to get a little hazy. It seems no two patients are told exactly the same thing. It is certain that no two patients will experience the same pacing of results.
What To Do About Suspicious Spots
Remember, your skin is constantly changing, repairing itself, and evolving. Just because you notice a new bump or a scab over a mole doesnt mean you have to panic about cancer. However, if you notice any of the melanoma signs above, including a mole that feels itchy, develops a scab or crust, feels tender, or is growing in size, visit your doctor.
One way to help your doctor is by keeping track of the shape and size of your moles so that you can log changes throughout the years and supplement in-office skin checks. Knowledge is power when it comes to protecting yourself against skin cancer. Make sure you set up regular appointments with your doctor to keep skin safe.

What Are Some Of The Lesser
Some of the less common skin cancers include the following:
Kaposi sarcoma is a rare cancer most commonly seen in people who have weakened immune systems, those who have human immunodeficiency virus /AIDS and people who are taking immunosuppressant medications who have undergone organ or bone marrow transplant.
Signs and symptoms of Kaposi sarcoma are:
- Blue, black, pink, red or purple flat or bumpy blotches or patches on your arms, legs and face. Lesions might also appear in your mouth, nose and throat.
Merkel cell carcinoma
Merkel cell carcinoma is a rare cancer that begins at the base of the epidermis, the top layer of your skin. This cancer starts in Merkel cells, which share of the features of nerve cells and hormone-making cells and are very close to the nerve ending in your skin. Merkel cell cancer is more likely to spread to other parts of the body than squamous or basal cell skin cancer.
Signs and symptoms of Merkel cell carcinoma are:
- A small reddish or purplish bump or lump on sun-exposed areas of skin.
- Lumps are fast-growing and sometimes open up as ulcers or sores.
Sebaceous gland carcinoma
Sebaceous gland carcinoma is a rare, aggressive cancer that usually appears on your eyelid. This cancer tends to develop around your eyes because theres a large number of sebaceous glands in that area.
Signs and symptoms of sebaceous gland carcinoma are:
- A painless, round, firm, bump or lump on or slightly inside your upper or lower eyelid.
Dermatofibrosarcoma protuberans
A Primer On Skin Cancer
Malignant melanoma, especially in the later stages, is serious and treatment is difficult. Early diagnosis and treatment can increase the survival rate. Nonmelanoma skin cancers include basal cell carcinoma and squamous cell carcinoma. Both are common and are almost always cured when found early and treated. People who’ve had skin cancer once are at risk for getting it again they should get a checkup at least once a year.

Skin cancer is actually one of the easiest cancers to find. Thats because skin cancer usually begins where you can see it.
You can get skin cancer anywhere on your skin from your scalp to the bottoms of your feet. Even if the area gets little sun, its possible for skin cancer to develop there.
You can also get skin cancer in places that may surprise you. Skin cancer can begin under a toenail or fingernail, on your genitals, inside your mouth, or on a lip.
