Skin cancer is the most common type of cancer worldwide, yet it remains one of the most preventable and treatable forms of cancer when caught early. Understanding the signs, symptoms, and risk factors can empower individuals to take proactive steps toward early detection and treatment. While the topic can feel overwhelming, knowledge truly is power when it comes to safeguarding your health. Dr. Stephen Bou Abbse, a highly regarded dermatologist, underscores the importance of regular skin checks and maintaining awareness of any changes to your skin. In this blog, we’ll delve into the critical signs of skin cancer, why they occur, and how you can actively monitor your skin for any concerning changes.
What is Skin Cancer?
Skin cancer arises when skin cells undergo abnormal growth, typically due to DNA damage caused by ultraviolet (UV) radiation from sunlight or artificial sources like tanning beds. This damage disrupts the normal lifecycle of skin cells, leading to unchecked growth that can form tumors. While skin cancer can develop anywhere on the body, it most frequently occurs on areas that receive the highest sun exposure, such as the face, neck, arms, and hands.
There are three primary types of skin cancer, each with unique characteristics. Basal Cell Carcinoma (BCC) is the most common but least aggressive type, often appearing as a pearly bump or sore that doesn’t heal. Squamous Cell Carcinoma (SCC), the second most common, can manifest as scaly red patches or open sores that may spread if untreated. Finally, Melanoma, the deadliest form, often presents as an irregular mole or dark spot and requires immediate medical attention. By understanding these distinctions, you can better identify potential issues and seek help promptly.
The ABCDE Rule for Identifying Melanoma
Melanoma, while less common than basal or squamous cell carcinoma, accounts for the majority of skin cancer-related deaths. Early detection significantly improves survival rates, which is why Dr. Bou Abbse advocates using the ABCDE rule to evaluate moles or pigmented lesions:
- A – Asymmetry: Normal moles are generally symmetrical, meaning one half mirrors the other. If a mole appears uneven or irregular, it may warrant further examination.
- B – Border: Healthy moles have smooth, even borders. A mole with jagged, scalloped, or poorly defined edges should raise concern.
- C – Color: A single uniform color is typical of a benign mole. Moles with multiple colors, such as shades of brown, black, red, or even blue, are more likely to be malignant.
- D – Diameter: While not all large moles are cancerous, any mole larger than 6mm (about the size of a pencil eraser) deserves attention. Smaller moles can also be dangerous, so size should not be the sole criterion.
- E – Evolving: The most important sign of potential melanoma is change. Any mole that grows, changes shape or color, or develops new symptoms like itching, bleeding, or crusting should be examined by a dermatologist immediately.

Other Warning Signs to Watch For
Skin cancer doesn’t always present as a mole or pigmented lesion. Dr. Bou Abbse emphasizes that other changes in your skin can also signal a problem. One common sign is a sore that doesn’t heal. Persistent sores, especially those that bleed, ooze, or crust over, may indicate basal or squamous cell carcinoma. These lesions are often mistaken for minor skin irritations or injuries but should not be ignored if they persist beyond a few weeks.
Another potential warning sign is the appearance of new growths or lumps. Skin cancer can sometimes look like a small, shiny bump or nodule, particularly on sun-exposed areas like the face and hands. Rough, scaly patches that resemble eczema or psoriasis may also be a sign of squamous cell carcinoma, especially if they persist or worsen over time. Dark spots or patches of skin that appear suddenly or change in appearance are another red flag. Finally, any skin lesion that becomes painful or tender to the touch could indicate an underlying issue and should be assessed promptly.
Who is at Risk?
While skin cancer can affect anyone, certain factors significantly increase your risk. Dr. Bou Abbse highlights that individuals with fair skin, freckles, or red/blonde hair are more prone to UV damage due to lower levels of melanin, the pigment that provides some natural protection against harmful rays. However, people with darker skin are not immune and should also remain vigilant.
Prolonged sun exposure, particularly without adequate protection, is another major risk factor. Those who spend extensive time outdoors for work or leisure are at greater risk, especially if they frequently experience sunburns. A family history of skin cancer also raises the likelihood of developing the condition, as does the use of tanning beds, which emit concentrated UV radiation. Additionally, individuals with weakened immune systems, such as organ transplant recipients or those undergoing chemotherapy, face a higher risk due to reduced skin defenses.
How to Perform a Self-Skin Exam
Conducting regular self-examinations is one of the most effective ways to detect skin cancer early. Dr. Bou Abbse advises making this a monthly habit to familiarize yourself with your skin’s normal appearance, allowing you to identify changes more easily. Begin in a well-lit room with a full-length mirror and a handheld mirror to examine hard-to-reach areas.
Start by inspecting your face, paying close attention to your nose, lips, and ears. Move down to your neck, chest, and torso, using the mirrors to check your back and shoulders. Examine your arms, hands, and nails, as skin cancer can develop in less obvious places like the spaces between your fingers or under your nails. Don’t forget to inspect your legs, feet, and soles, as well as your scalp. Use a comb to part your hair and thoroughly examine the skin underneath. If you notice any unusual spots or changes, take a photo to track their progression and consult a dermatologist if needed.

The Role of Regular Dermatology Check-Ups
While self-exams are invaluable, professional skin screenings are essential for comprehensive care. Dermatologists have the expertise and tools to detect early-stage skin cancer that may not be visible to the naked eye. Dr. Bou Abbse recommends annual check-ups for most individuals, though those with a higher risk may need more frequent visits. During these appointments, dermatologists may use advanced diagnostic techniques like dermoscopy to examine suspicious lesions more closely.
Professional check-ups also provide an opportunity to discuss any concerns or questions about your skin. Whether it’s a mole that’s changed or a new growth that’s causing anxiety, a dermatologist can provide clarity and, if necessary, initiate treatment before the condition worsens.
Tips for Prevention
Preventing skin cancer begins with protecting your skin from harmful UV rays. Dr. Bou Abbse advises using a broad-spectrum sunscreen with SPF 30 or higher daily, even on cloudy days. Reapply sunscreen every two hours and after swimming or sweating to maintain its effectiveness.
Avoid peak sun hours between 10 AM and 4 PM, when UV radiation is strongest, and seek shade whenever possible. Protective clothing, such as long-sleeved shirts, wide-brimmed hats, and UV-blocking sunglasses, adds an extra layer of defense. Importantly, steer clear of tanning beds, which are a leading cause of skin cancer among young people. Instead, opt for safer alternatives like self-tanning products.
When to Seek Medical Attention
If you notice any suspicious changes in your skin or are unsure about a particular spot, consult a dermatologist promptly. Early intervention can prevent minor issues from becoming life-threatening conditions. Dr. Bou Abbse emphasizes that skin cancer is most treatable in its earliest stages, making timely diagnosis critical for positive outcomes.
Skin cancer is a serious but highly preventable and treatable condition. By staying vigilant, performing regular self-exams, and seeking professional care, you can take charge of your skin health and reduce your risk. Dr. Stephen Bou Abbse’s expert advice serves as a reminder that early action can make all the difference. Remember, your skin is your body’s largest organ—nurture and protect it with the care it deserves.
