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.
The Importance Of Early Detection
The early detection of skin cancer is vital and can reduce a patients risk of disfigurement through removal, or in the most serious of cases death. It is therefore very important to get to know your own skin so that you can recognise any signs of change that may be a potential skin cancer or pre cancerous skin legion.Please be aware that it is important to check your skin both thoroughly and regularly to ensure you identify abnormal changes as early as possible.It is also important to seek immediate professional advice from your GP or skin specialist / dermatologist should you be concerned or uncertain about anything you identify.There are two main types of skin cancer, Non-Melanoma skin cancers and Melanoma skin cancer, which is the most serious type of skin cancer. Below you will find examples of each of the various forms of skin cancer within these categories, with tips and symptoms to help you understand what you should be looking for when checking your skin.Further in-depth information on all types of skin cancer including: signs, symptoms, causes and risk factors, treatments and prevention guidelines can be found in the ‘Types of Skin Cancer’ section.
Basal Cell Carcinoma
Basal Cell Carcinoma is the most common type of skin cancer. It grows slowly over months and years and may damage nearby tissues and organs if left untreated.
Squamous Cell Carcinoma
What To Look For
Any new spots that appear on the skin could potentially be skin cancer, considering that one in five people will develop at least one skin cancer in their lifetime. Definitively distinguishing the different types of skin cancer requires a biopsy and microscopic evaluation, but the general appearance of these tumors also differs to some degree.
- Basal cell carcinomas are often shiny and have been described as “pearlescent.” They may be flat, raised, or dome-shaped, and are often pink, pale, or flesh-colored. On careful inspection, tiny blood vessels may be visible when compared with the surrounding skin. Basal cell cancer characteristically is very often ulcerated and has been called a rodent ulcer because it looks like a mouse has gnawed it.

- Squamous cell carcinomas are often raised and feel crusty to touch. They can appear scaly and may be ulceratedthat is, have a central depression that is lighter and flatter than the surrounding area. These cancers sometimes bleed, ooze, or form scabs.

Less Common Skin Cancers
Uncommon types of skin cancer include Kaposi’s sarcoma, mainly seen in people with weakened immune systems sebaceous gland carcinoma, an aggressive cancer originating in the oil glands in the skin and Merkel cell carcinoma, which is usually found on sun-exposed areas on the head, neck, arms, and legs but often spreads to other parts of the body.
How To Detect Skin Cancer
When it comes to skin cancer, we have some good news and some bad news.
First, the bad news: skin cancer is the most commonly diagnosed cancer in the United States. Each year, nearly 5 million people are treated for skin cancer, and in the last three decades, more Americans have had skin cancer than all other cancers combined.
But heres the good news: You can often see the early warning signs of skin cancer…without an x-ray or blood test or special diagnostic procedure. If you know what to look for and take action when you see it, most skin cancers can be detected and treated at early stages, when they are most curable.
Even for melanoma, a more dangerous skin cancer type that is more likely to spread to other body areas, the five-year survival rate is 99% for people whose melanoma is detected and treated before it spreads to the lymph nodes.

How Do You Spot A Skin Cancer
Skin cancers dont all look the same, but there are signs to look out for, including:
- a spot that looks and feels different from other spots on your skin
- a spot that has changed size, shape, colour or texture
- a sore that doesnt heal within a few weeks
- a sore that is itchy or bleeds.
There is no set guideline on how often to check for skin cancer, but checking your skin regularly will help you notice any new or changing spots. If you have previously had a skin cancer or are at greater risk of developing skin cancer, ask your doctor how often you should check your skin.
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.

How To Check Your Skin
- Make sure you check your entire body, as skin cancers can sometimes occur on parts of the body that are not exposed to the sun, such as the soles of the feet, between fingers and toes and under nails.
- Undress completely and make sure you have good light.
- Use a mirror to check hard to see spots, like your back and scalp, or get a family member, partner or friend to check for you.
Symptoms On Black And Brown Skin
On dark skin, it may be easier to feel a lesion than see it. People with black skin may be more likely to find a lesion on a part of the body that has little exposure to the sun, according to the American Academy of Dermatology.
Skin cancer can affect people with any skin color, but those with brown or black skin are more likely to receive a diagnosis at a later stage. This may be due to a lack of awareness of how skin cancer appears on skin colors other than white.
Anyone who notices an unusual change in their skin should seek medical advice as soon as possible.
The medical community has developed two ways to spot the early symptoms of melanoma. This is the most dangerous type of skin cancer.
A person can use the ABCDE method or the ugly duckling method.
Spot The Cancer You Can See When Its Easiest To Treat
The worlds most common cancer is a relentless disease that strikes one in five people by age 70. The good news is that 99 percent of all cases are curable if they are diagnosed and treated early enough. But in order to stop skin cancer, we have to spot it on time.
Skin cancer is the cancer you can see. Unlike cancers that develop inside the body, skin cancers form on the outside and are usually visible. Thats why skin exams, both at home and with a dermatologist, are especially vital.
Early detection saves lives. Learning what to look for on your own skin gives you the power to detect cancer early when its easiest to cure, before it can become dangerous, disfiguring or deadly.
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.

The Abcde Of Melanoma:
Nodular Melanomas do not typically follow these guidelines – see below for guidance
You should consult your doctor if you develop any of the following signs:
- Changing shape, particularly getting an irregular outline.
- Changing colour/getting darker, becoming patchy or multi-shaded.
- An existing mole getting bigger or a new mole growing quickly.
- A mole starts to itch, becomes painful, starts bleeding, becomes crusty or inflamed.
How to detect Nodular Melanoma:Nodular melanomas do not follow the ABCDE of Melanoma outlined above.They are more even in colour and have even edges.They grow fast, downward and become quickly invasive .A good way to remember what to look out for is EFG:E = ELEVATED, F = FIRM TO TOUCH, G = GROWINGNodular melanomas are usually black, but occasionally are blue, grey, white, brown, tan, red or skin tone. The images below show some examples, but if you detect any lump on the skin that is growing quickly – seek professional medical advice immediately.
Examples of Arcal Lentiginous MelanomaUnlike other melanomas Arcal Lentiginous Melanoma is usually located on the palms of hands, soles of feet and under nails and appears as a black discolouration.This type of melanoma is more common in Asians and African-Americans and less common among Caucasians and can advance faster than Lentigo Maligna and Superficial Spreading Melanoma.These are examples of Arcal Lentiginous Melanoma:

Identifying Skin Cancer: 37 Photos You Need To See
As we head into summer, its time to kick your safe skin practices into high gear. All individuals should apply a broad spectrum SPF every day, and watch their local UV forecast for daily updates when outside activities are planned.
Why? Skin cancer is the most common form of cancer in the United States. One in five Americans will be diagnosed with the disease in his or her lifetime. There are more new cases of skin cancer every year than breast, prostate, lung and colon cancers combined, according to the U.S. Centers for Disease Control and Prevention.
Although family history and your natural skin pigmentation play a role in your risk, the number-one thing that causes skin cancer is exposure to UV rays.
Erin Gilbert, M.D., Ph.D., a spokesperson for the Skin Cancer Foundation, offered these guidelines to weather.com in 2014: Avoid the sun when its at its peak wear sun-protective clothes, such as a hat always wear a broad-spectrum SPF. Reapply sunscreen every two hours, or after swimming or sweating.
Its a myth that most sun damage occurs in childhood, so theres nothing you can do about it as an adult, Dr. Gilbert said.
Twenty-three percent of sun damage happens before youre 18, but it is cumulative. Its never too late to start protecting yourself, she said. Your melanoma risk doubles if youve had more than five severe sunburns at any age. Dont let a sunburn or a tan deter you from seeing your dermatologist or wearing sun screen the next day.

How Can I Tell If I Have Skin Cancer
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.
See A Suspicious Spot See A Dermatologist
If you find a spot on your skin that could be skin cancer, its time to see a dermatologist. Found early, skin cancer is highly treatable. Often a dermatologist can treat an early skin cancer by removing the cancer and a bit of normal-looking skin.
Given time to grow, treatment for skin cancer becomes more difficult.

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
Look Out For An Ugly Duckling
The Ugly Duckling is another warning sign of melanoma. This recognition strategy is based on the concept that most normal moles on your body resemble one another, while melanomas stand out like ugly ducklings in comparison. This highlights the importance of not just checking for irregularities, but also comparing any suspicious spot to surrounding moles to determine whether it looks different from its neighbors. These ugly duckling lesions or outlier lesions can be larger, smaller, lighter or darker, compared to surrounding moles. Also, isolated lesions without any surrounding moles for comparison are considered ugly ducklings.

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.
How Is Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.
Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

Checking Yourself And Your Loved Ones
Start by checking your entire body, including skin not normally exposed to the sun. You could ask for help from someone else to check difficult-to-see areas, such as your back, neck and scalp.
We recommend that you follow the Ugly Duckling rule. The idea behind the Ugly Duckling rule is that you compare your moles with each other. If any mole stands out or looks different from that of nearby moles, it is the ugly duckling, and we advise you contact a doctor to get an expert opinion.
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
