ABCDEF's of Changing Moles & Melanoma

Dr. Eugene Conte • February 2, 2017
Moles & Melanoma | Pine Belt Dermatology
Before you read this article about Skin Cancer consider the following facts:

* Skin Cancer is the most common cancer of all cancers seen today.

* More than 3.5 million non-melanoma skin cancers in more than 2 million are          diagnosed in the United States annually.

  • Current estimates are that 1 in 5 Americans will develop skin cancer in their lifetime.
  • A recent report estimated that 1 in 28 people in the United States will develop some variation of skin cancer in their lifetime & 1 in 50 will develop melanoma.
  • Melanoma incidence rates have been increasing for the last 30 years.
  • The incidence rate of Melanoma has increased by about 2.8% per year since 1981.
  • Caucasians and men older than 50 are at a higher risk of developing Melanoma than the general population.
  • The incidence in men ages 80 and older is 3 times higher than women of the same age.
  • Melanoma incidence rates in Caucasians are 5 times higher than in Hispanics and 23 times higher than in African Americans.
  • Although before age 40, Melanoma incidence rates are twice as high in woman then in men, after 40, rates are higher in men than women.
  • Melanoma is the most common form of cancer for young adults 25-29 years old and the second most common form of cancer for adolescents and young adults 15-29 years old.
  • Melanoma is increasing faster in females 15 to 29 years old than males in the same age group.
  • Melanoma in Caucasian woman under the age of 44 has increased 6.1% annually, which may reflect recent trends in indoor tanning.
  • While Melanoma in children is extremely rare, from 1973 to 2009 the rate of Melanoma increased by about 2% per year among Caucasian children from newborn to age 19 in the United States.
  • The 5-year survival rate for people whose Melanoma is detected early and treated before it has spread to the lymph nodes is 98%.
  • About 75% of skin cancer deaths are from Melanoma.
  • On average, 1 American dies from Melanoma every hour.
  • Two thirds will be men and one third will be women.
With early detection and treatment, skin cancer is highly curable. The most common warning signs of skin cancer include changes in size, shape, or color of a mole or other skin lesion and or the appearance of a new growth on your skin.

SKIN CANCER AFFECTS EVERYONE

No matter your skin color, you can get skin cancer. Some people have a higher risk of developing skin cancer than others Age is the key factor, but there are many other risk factors.

People with a higher risk for skin cancer have:

** Light colored skin

** Skin that burns or freckles rather than tans

** Blond or red hair

** More than 50 moles on your body

** Irregularly-shaped or darker moles (nevi) or so called “atypical”

** Use (or use) of indoor tanning devices such as tanning beds or sunlamps

Your medical history also can increase your risk of getting skin cancer. You have a much greater risk of developing skin cancer if you have:

** History of sunburns, especially blistering sunburns

** Have received an organ transplant

** Had skin cancer (or a blood relative has /had skin cancer)

** A weakened immune system

** Received long term x-ray therapy, such as x-ray treatments for acne

** Been exposed to cancer-causing compounds such as arsenic or coal

** An area of your skin that has been badly burned many years ago either by an accident of by the sun.

TYPES OF SKIN CANCER

The most common types of skin cancer are:

BASAL CELL CARCINOMA (BCC)

  BCC is the most common type of skin cancer.BCC appears on the skin in many shapes and sizes. You make see a dome-shaped growth with visible blood vessels; a shiny, pinkish patch; or a sore that heals, and then returns. BCC usually develops on skin that receives lots of sun, such as the scalp, nose, neck, and hands. BCC rarely spreads to other of the body, but it can grow deep into tissues and bone if not treated early.

SQUAMOUS CELL CARCINOMA (SCC)

   SCC is the second most common type of skin cancer. SCC appears on the skin in many shapes. You can see a crusted or rough bump that grows and bleeds; or a sore that does not heal, or heals and then returns. SCC commonly develops on the skin that is exposed to sun, such as the face, ears, lips, back of the hands, arms, and legs. SCC can also develop from a previous precancer located on the skin. (We will discuss this latter in this article).

SCC can also develop on areas of the body that are not exposed to sun, such inside your mouth or on the genitals. Smoking or chewing tobacco may increase your risk of getting SCC in your mouth or throat. Left untreated, SCC can spread internally to other parts of your body, making treatment difficult.

MELANOMA

   This is the deadliest form of skin cancer. Melanoma may develop on normal skin or in an existing mole. A change to the shape, color, or diameter (size) of a mole can be a sign of melanoma. Other changes to watch for include a mole that becomes painful or begins to bleed or itch.

Some melanomas develop on normal skin. A new growth, particularly one that goes not match what your other moles look like, could be a melanoma.

Melanoma can also develop under fingernails or toenails. This may look like a brown or black streak or smudge underneath the nail.

Although melanoma is more common in those people with light colored skin, people with skin of color can also get melanoma. In skin of color, melanoma usually appears on a palm of the hand, or the sole of the foot, under the nail, in the mouth, or on the genitals.

THE ABCDEF’s OF MELANOMA DETECTION

When melanoma is caught early and treated, the cure rate is nearly 100%.

Performing skin self-examinations can help you find skin changes that could be an early melanoma or other types of skin cancer.

When looking at your skin for signs of melanoma, it helps to keep in mind the ABCDEF’s of Melanoma.

  • A stands for ASYMMETRY; one –half of the lesion does not look like the other half.
  • B stands for BORDER; irregular, scalloped or poorly defined border.
  • C stands for COLOR; varied from one spot to another; shades of brown, black; and sometimes red, white or blue.
  • D stands for DIAMETER; melanomas are most often greater than 6 millimeters. (The size of a pencil eraser) when diagnosed, but can also be smaller.
  • E stands for EVOLVING; a mole or skin growth that looks different from the rest or is changing in size, shape, or color.
  • F stands for FRIED EGG; this is an additional change I tell my patients to look for in which the mole begins to look like a” fired- egg” or a” bulls -eye”
Before I discuss skin examinations I want to educate my readers on the most common new onset skin growth you may see developing on your skin especially if you live or have lived in Arizona. They are called:

 

ACTINIC KERATOSES (AK)

    Actinic Keratoses (AK’s) are very common skin growths . AKs are considered precancerous. If they are left untreated, an AK may turn in a squamous cell carcinoma (SCC).

Most AKs are dry, scaly, rough-textured spots on the skin. AKs form on skin that receives lots of sun, such as on the head, including the lips and scalp; arms and hands. Woman frequently can get AKs on the back of their legs.

If you are concerned that you may be developing AK’s one of the most important signs a patient will relate to me is that “the spot forms, scale heaps up on the their skin, disappear and then returns a short time later from days to weeks later then the process starts over again”.

SKIN EXAMS CAN FIND SKIN CANCERS EARLY

   There are two types of skin examinations. A self-exam that involves checking your skin for the signs of changes I have described in this article.

Your dermatologist performs the other type of skin exam which will be more extensive. How often a patient should have a skin exam will vary from patient to patient. I tell my patients “at least once a year unless I tell you differently” and to

Think of your skin exam as the “annual physical for the largest organ in the body”.

EARLY TREATMENT HAS A HIGH CURE RATE

    Caught early and properly treated, skin cancer can be cured. Even melanoma, which can be deadly, has a cure rate of almost 100% when treated early.

Proper treatment begins with the right diagnosis. To diagnose skin cancer, a dermatologist performs a skin biopsy. This is the best and most precise way to diagnose a skin cancer. Your dermatologist can perform a biopsy during an office visit.

To perform a biopsy, your dermatologist will remove either the entire suspicious growth or part of it depending on the size of the growth.

The removed skin will be sent to the dermatopathology lab where it will be examined under the microscope. If the diagnosis is skin cancer, your dermatologist will consider the size and location of the skin cancer, and your general health to determine the best treatment for you. When caught early and the entire growth is treated in total further treatment may not be needed. However if further treatment is needed your dermatologist will discuss your treatment options and make recommendations.

PREVENT - DETECT - LIVE

Sun exposure is the most common preventable risk factor for precancers, all skin cancers including melanoma. The following can help you detect and prevent new skin cancers:

*** Have an annual skin exam by your dermatologist.

*** Perform your skin self-examination.

*** If you notice anything changing, growing or bleeding on your skin make an appointment with your dermatologist immediately.

*** Protect your skin every day by:
  • Seeking shade
  • Protect your skin when around water, snow and sand
  • Wearing protective clothing
  • Educate your children, family and friends.
  • Never use a tanning bed
*** Generously apply sunscreens that offer broad-spectrum (UVA and UVB) protection, water resistance, and a Sun Protection Factor (SPF) of 30 or more.

Wearing sunscreen every day, studies show, can reduce the risk of developing melanoma by 50%. Be sure to apply the sunscreens to all exposed areas of your skin before going outside. If you are swimming or sweating a lot you should apply your sunscreen at least every 2hours during your times of exposure.

At Pine Belt Dermatology & Skin Cancer Center , we understand that selecting the right skincare products can be challenging. While many over-the-counter (OTC) options promise results, not all skin concerns can be addressed with these products. Knowing the difference between OTC and prescription treatments helps you make educated decisions and recognize when to seek professional care. If you are treating acne, eczema, rosacea, or signs of aging, upgrading your treatment plan at the right time can improve your skin health and confidence. Understanding Over-the-Counter Skin Treatments Over-the-counter skincare products are available without a prescription and are intended for mild to moderate skin concerns. When used consistently, many contain ingredients that help maintain healthy skin. Common OTC ingredients include: Salicylic acid for acne Benzoyl peroxide to reduce acne-causing bacteria Retinol for fine lines and uneven texture Hydrocortisone cream for minor itching and irritation Moisturizers with ceramides or hyaluronic acid to heal the skin barrier These products are a good starting point for mild conditions. However, because OTC treatments use lower-strength active ingredients, they may not be effective for chronic or serious skin issues. When Prescription Skin Treatments May Be Necessary Prescription treatments use stronger active ingredients and are customized to your specific skin condition. A dermatologist can diagnose the underlying cause and recommend medications that address the problem more effectively than OTC products. Prescription treatments may include: Oral medications for moderate to severe acne Prescription-strength retinoids Medications to manage eczema or psoriasis Treatments for rosacea and chronic redne Prescription creams for hyperpigmentation or melasma Antifungal or antibacterial medications for skin infections These therapies are chosen based on your medical history, skin type, and treatment goals to maximize results and minimize side effects. Time to Upgrade Your Treatment While many start with OTC products, some situations require a dermatology appointment. Consider seeing a dermatologist if: Your skin condition has not improved after several weeks of steady OTC treatment. Acne is causing painful cysts, nodules, or permanent scarring. Rashes, redness, or irritation continue to worsen. You experience frequent flare-ups of eczema, psoriasis, or rosacea. You notice new or changing skin growths or unusual spots. Your skin concern is affecting your confidence or quality of life. Early treatment has the potential to prevent conditions from getting worse and minimize the chances of long-term skin damage. Why Professional Assessment Matters Many skin conditions look similar, making self-diagnosis challenging. For example, stubborn acne may be rosacea, and chronic dry patches could indicate eczema, psoriasis, or another condition. A board-certified dermatologist can accurately diagnose your skin concern and develop a customized treatment plan. Professional guidance also helps you avoid spending time and money on ineffective products. Healthy Skin Starts with the Right Treatment Over-the-counter products are important for daily skincare, but they may not treat complex or persistent concerns. Transitioning to prescription treatment at the right time can greatly improve your skin’s appearance and long-term health. At Pine Belt Dermatology & Skin Cancer Center , our team offers complete evaluations and customized treatment plans for acne, eczema, rosacea, hyperpigmentation, skin cancer screenings, and other skin conditions. If your current skincare routine is not resulting in success, we are here to help you achieve healthier, more confident skin.

At Pine Belt Dermatology & Skin Cancer Center, we believe education is key to protecting and maintaining healthy skin. July is significant for skin health, featuring both UV Safety Awareness Month and World Skin Health Day on July 8 . These occasions highlight the importance of sun protection and raise awareness of common concerns, such as hyperpigmentation and melasma . Understanding how ultraviolet (UV) exposure affects your skin helps prevent long-term damage and supports a healthier, more even complexion. Why UV Protection Matters The sun emits ultraviolet rays that can damage skin even on cloudy days. While many associate UV exposure with sunburn, its effects are broader. Repeated UV exposure accelerates skin aging, increases skin cancer risk, and contributes to pigmentation disorders. Common effects of excessive UV exposure include: • Sunburn and skin irritation • Premature aging, including fine lines and wrinkles • Dark spots and uneven skin tone • Increased risk of skin cancer • Worsening of hyperpigmentation and melasma Daily sun protection is one of the most effective ways to maintain healthy skin and reduce preventable damage. What Is Hyperpigmentation? Hyperpigmentation is a common condition where areas of skin become darker than the surrounding tissue due to excess melanin production. Multiple factors can contribute to hyperpigmentation, including: • Sun exposure • Acne scars and inflammation • Hormonal changes • Skin injuries or irritation • Certain medications While hyperpigmentation is mostly harmless, many seek treatment to improve skin tone as well as restore confidence. Understanding Melasma Melasma is a type of hyperpigmentation that shows up as brown or gray-brown patches, typically on the cheeks, forehead, nose, and upper lip. Melasma is frequently associated with: • Hormone changes during pregnancy • Birth control medications • Hormone replacement therapy • Genetic predisposition • Sun exposure Although melasma is not dangerous, it can be difficult to treat because UV exposure frequently triggers or worsens it. Even minimal sun exposure can increase pigment production and make discoloration more noticeable. Protecting Your Skin from UV Damage Whether you are concerned about skin cancer, hyperpigmentation, or melasma, daily sun protection is essential. Dermatologists suggest: • Using sun lotion with SPF 30 or higher every day • Reapplying sunscreen every two hours when outdoors • Wearing wide-brimmed hats and protective clothing • Seeking shade during peak sunlight hours • Wearing UV-protective sunglasses • Avoiding tanning beds Consistent sun protection helps prevent new pigmentation issues. World Skin Health Day: A Reminder to Prioritize Skin Care Observed annually on July 8, World Skin Health Day encourages preventive steps to maintain healthy skin. This is a reminder to perform regular self-exams, schedule dermatology visits, and address concerns early. If you notice persistent dark spots, changes in pigmentation, or new skin lesions, seek an expert assessment to determine the cause and identify treatment options. Supporting Healthy Skin Year-Round UV Safety Awareness Month and World Skin Health Day remind us that protecting your skin is an investment in long-term health. Practicing sun safety and understanding conditions like hyperpigmentation and melasma help preserve your skin’s health, appearance, and function. At Pine Belt Dermatology & Skin Cancer Center, our team provides personalized evaluations and treatments for pigmentation concerns, sun-damaged skin, and overall skin health.

When a ‘Rash’ Might Be Something More Serious At Pine Belt Dermatology & Skin Cancer Center, we recognize that rashes are common and frequently resolve quickly with minimal treatment. However, some rashes may signify underlying conditions that require prompt medical attention. Identifying when a rash is more than a minor irritation is key to protecting your health. Comprehending Common vs. Concerning Rashes Most everyday rashes result from irritants, allergies, heat, or minor infections and typically improve within a few days with over-the-counter treatments. However, if a rash lasts longer, worsens, or appears with other symptoms, it may signal a more serious issue. Identifying the difference between a routine rash and one that requires medical evaluation helps avoid complications and ensure appropriate care. Warning Signs to Watch For Certain features may indicate a rash requires clinical assessment, including: Rapidly spreading or worsening rash Severe pain, swelling, or blistering Signs of infection such as pus, warmth, or red streaks Fever or flu-like symptoms accompanying the rash A rash that does not improve after several days of treatment Dark, purple, or bruised-looking areas on the skin For example, a rash with fever may indicate a viral or bacterial infection, whereas painful blistering can suggest conditions such as shingles. In rare cases, rashes may signal autoimmune disorders or severe allergic reactions. Rashes That May Point to Underlying Conditions Some rashes may be linked to broader health concerns, including conditions that cause inflammation in the skin and other organs: Allergic reactions that may escalate into further severe responses Infections that spread beyond the skin if untreated Medication reactions that require immediate adjustment Persistent or unusual skin changes may be early signs of skin cancer or precancerous conditions, especially if they do not heal or continue to change over time. Why Early Evaluation Matters Delaying care for a worrisome rash may allow the underlying condition to progress. Early diagnosis improves treatment outcomes and helps prevent discomfort and complications. A dermatology specialist can assess the rash’s appearance, location, and progression, and may recommend diagnostic tests if needed. This approach assures treatment addresses the underlying cause, not just the visible symptoms. When to See a Dermatology Specialist If you are unsure about your rash, it is best to err on the side of caution. Consider seeking care if: The rash is persistent, painful, or unusual in appearance Over-the-counter treatments are not effective You experience additional symptoms such as fever or fatigue The rash interferes with your daily comfort or quality of life At Pine Belt Dermatology & Skin Cancer Center, our experienced providers supply comprehensive skin evaluations and customized treatment plans. We take time to understand your symptoms and deliver clear, effective solutions tailored to your needs. Protecting Your Skin and Your Health While many rashes are minor, some may be early warning signs of more serious health concerns. Monitoring skin changes and pursuing prompt medical advice can produce a notable effect. If you notice a rash that does not seem right, do not ignore it. Schedule a consultation with Pine Belt Dermatology & Skin Cancer Center for expert evaluation and peace of mind. Your skin is an important indicator of your overall health, and taking it seriously supports ongoing well-being.
