Skin cancer is one of the most common kinds of cancer around the world, affecting millions of people each year. It occurs when the skin cells grow unusually & form malignant (cancerous) tumors. Among the diverse types of skin cancer, melanoma is the most serious and can develop from moles on the skin. Moles are small, colored marks on the skin made up of clusters of pigmented cells. While most moles are harmless, some can become cancerous, turning into melanoma. The danger lies in melanoma spreading to other parts of the body if not detected and treated early. Awareness and early detection of cancerous moles are crucial in the fight against skin cancer.
Identifying unusual changes in your moles can make a significant difference. Recognizing the early signs of a potentially cancerous mole can lead to timely medical intervention, which increases the chances of successful treatment. This is why understanding the characteristics of moles and regularly checking your skin for any changes are vital steps in protecting your health.

What Are Moles?
Moles are small, often brown or black spots that appear on the skin. They can be flat or raised, and their size can vary. Most people have moles, & they are usually harmless. Moles are created when skin cells, known as melanocytes, develop in clusters instead of spreading evenly across the skin.
Different Types of Moles and Their Characteristics
Moles come in various types, and knowing these can help you understand what’s normal and what’s not:
1. Common Moles– These are small, round, or oval, with a smooth edge, often brown, black, or skin-colored. Most people have them, and they are usually harmless.
2. Dysplastic (Atypical) Moles– These are larger than typical moles, with irregular shapes and uneven color. These moles are more likely to grow into melanoma, a kind of skin cancer.
3. Congenital Moles– These are present at birth and can vary in size. Larger congenital moles have a higher risk of becoming cancerous later in life.
Explanation of How Moles Form & Change Over Time
Moles form when melanocytes, the cells responsible for producing pigment in the skin, clump together. They usually appear during childhood and adolescence but can develop at any age. As you get older, moles may change in color, become raised, or even disappear. Some moles grow hair, while others might become darker after sun exposure. Although many moles change over time, rapid or unusual changes can indicate skin cancer.
When Moles Become Cancerous?
Melanoma is the most severe category of skin cancer, and it often begins in moles or pigmented skin. Not all moles turn cancerous, but if a mole changes shape, color, or size quickly, it could indicate melanoma. Early detection is important because melanoma can spread to other body parts if left untreated.
The ABCDEs of Melanoma Detection:
– A for Asymmetry– If one half of the mole looks different from the other half.
– B for Border– If the edges are irregular, blurry, or ragged rather than smooth.
– C for Color– If the mole has different shades of brown, black, red, or white or changes color over time.
– D for Diameter– If the mole is bigger than 6mm across, melanomas can sometimes be smaller.
– E for Evolution– If the mole changes in size, shape, and color or starts itching or bleeding.
The Significance of New Moles and Changes in Existing Ones
New moles can appear even in adulthood, but it could be a warning sign if you detect a new mole or changes to an existing one, such as growth, discoloration, or itching. It’s vital to monitor these changes closely, as they might indicate early-stage melanoma, which is highly treatable when caught early.
Identifying Cancerous Moles
Visual Guide to Cancerous vs. Non-Cancerous Moles
Non-cancerous moles are usually uniform in color, round or oval in shape, and remain stable over time. Cancerous moles, on the other hand, often have irregular borders, a mix of colors, and can change in appearance. A suspicious mole may stand out from others on your skin, usually referred to as the “ugly duckling” sign.
Symptoms & Signs That May Indicate a Mole Is Cancerous
In addition to the ABCDEs, symptoms like:
– Itching or tenderness around the mole.
– Bleeding or oozing.
– A sudden increase in size or a raised surface.
– Pain or discomfort in or around the mole.
These signs suggest the mole should be checked by a doctor.
The Role of Self-Examination & Regular Dermatological Check-Ups
Regular self-examinations can help you spot unusual moles early. Check your skin monthly using a mirror, and don’t forget hard-to-see areas like your back and scalp. It’s also important to schedule regular check-ups with a dermatologist, especially if you have many moles or a history of skin cancer. Dermatologists can perform professional skin exams to detect problems early.
Risk Factors For Cancerous Moles
1. Excessive Sun Exposure: The sun’s ultraviolet (UV) rays are the most typical cause of skin damage that can lead to cancerous moles. Prolonged sun exposure, especially without protection, increases the risk.
2. Fair Skin: People with lighter skin, blonde or red hair, & blue or green eyes have less melanin, the pigment that helps protect skin from UV rays. This makes them more susceptible to skin damage and cancer.
3. Atypical Moles: Some people have larger moles that are uneven in color or have irregular borders. These moles, known as atypical moles or dysplastic nevi, are more likely to become cancerous.
4. Family History: If your family has a history of melanoma or other skin cancers, you’re at a higher risk of getting cancerous moles.
5. Weakened Immune System: A weak immune system, whether due to illness or medication, can make it harder for your body to fight off abnormal cell growth, including skin cancer.
6. Tanning Beds: The UV radiation from tanning beds can also damage your skin and increase the likelihood of developing cancerous moles.
7. Age: While skin cancer can affect people of all ages, the risk increases as you get older due to accumulated sun exposure over time.
Prevention Of Cancerous Moles
1. Limit Sun Exposure: Try to avoid the sun during peak hours, typically between 10 a.m. & 4 p.m., when UV rays are strongest.
2. Wear Sunscreen: Use broad-spectrum sunscreen with an SPF of at least 30, even on overcast days. Reapply every 2 hours, mainly after swimming or sweating.
3. Protective Clothing: When outdoors, wear wide-brimmed hats, sunglasses, and clothing that protects your skin. Special clothing with UV protection is also available.
4. Avoid Tanning Beds: Avoid tanning salons, as artificial UV rays can be as harmful as the sun.
5. Regular Skin Checks: Check your skin regularly for new moles or differences from existing moles. Look for the “ABCDE” signs of melanoma:
– Asymmetry: One half of the mole doesn’t correspond with the other.
– Border: Irregular, ragged, or blurred edges.
– Color: Uneven shades of black, brown, tan, or even red or blue.
– Diameter: Bigger than the dimensions of a pencil eraser (about 6 mm).
– Evolving: Any changes in size, shape, color, or feeling.
6. See a Dermatologist: If you notice any suspicious changes in your moles, consult a dermatologist for an expert opinion. Early diagnosis improves the possibility of successful cancer treatment.
7. Healthy Lifestyle: Maintaining a balanced diet, staying hydrated, and avoiding smoking can strengthen your immune system and lower the overall risk of skin cancer.
Can Mole Removal Cause Cancer?
When a mole is removed, it’s typically because the mole looks suspicious or has changed in some way. This could mean it has changed in size, shape, color, or texture. Physicians remove these moles to examine them closely in a laboratory to check for cancer cells—a process known as a biopsy.
Now, to answer the question: “Can mole removal cause cancer?” The answer is no. Mole removal itself does not cause cancer. Removing a mole is a precautionary measure to prevent cancer if it appears abnormal or shows signs of melanoma. Doctors can detect cancer early by removing and testing the mole, which is critical for successful treatment.
There are different methods for removing a mole, and the choice depends on the mole’s size, location, and characteristics. These methods include:
– Shave biopsy: where the mole is shaved off the skin’s surface.
– Punch biopsy: where a tool removes a deeper section of the mole.
– Excisional biopsy: where the mole is cut out entirely, often with some surrounding skin.
After removal, the mole is sent to a pathology lab for examination. If the mole is benign or non-cancerous, no further treatment is needed. However, if it contains cancer cells, the patient will be advised on the next steps for treatment.
Are Cancerous Moles Painful?
Moles, in general, are common skin growths that most adults have, ranging from 10 to 40. They can be flat or raised, and while they are usually harmless, it’s essential to monitor them for any changes that could indicate a problem, such as skin cancer.
Pain or tenderness in moles can occur for various reasons unrelated to cancer. For instance, a pimple developing under a mole, an ingrown hair, friction from clothing, or a minor injury can all cause a mole to become painful or tender. However, if a mole becomes painful without an apparent reason, mainly if it also exhibits other warning signs of melanoma, it is advisable to have it checked by a healthcare professional.
It’s worth noting that new moles or changes in existing moles, such as those outlined in the ABCDE rule, warrant attention. Approximately 70% of melanomas start as new moles, so it’s crucial to be vigilant about any new growths on the skin.
Diagnosis For Cancerous Mole
When a mole looks suspicious, doctors follow several steps to determine if it is cancerous. The process involves visual inspections, special tools, and tests to confirm whether the mole is benign (non-cancerous) or malignant (cancerous). Here’s a simple explanation of how a cancerous mole is detected:
Steps Involved in Diagnosing a Cancerous Mole
1. Self-Examination
– What You Do: Regularly examine your skin for new moles or changes in existing ones. Use the “ABCDE” rule:
– Asymmetry: One half of the mole looks distinct from the other half.
– Border: The edges are irregular, not smooth.
– Color: Uneven colors like brown, black, red, or blue.
– Diameter: Larger than a pencil eraser (around 6mm).
– Evolving: Any changes in size, shape, or symptoms like itching or bleeding.
2. Consulting a Doctor
What Happens: If you find a mole that concerns you, visiting a dermatologist (skin specialist) is important. The doctor will inspect the mole visually, looking for any signs that suggest it might be cancerous.
What They Look For: The doctor will assess the mole’s size, shape, color, and texture to determine whether it resembles the common characteristics of melanoma (a type of skin cancer).
3. Dermatoscopy (Skin Magnification)
– What It Is: A dermatoscope is a handheld tool that magnifies the mole and uses light to see beneath the skin’s surface.
– Why It’s Done: This allows the dermatologist to examine the structure and patterns inside the mole, which helps identify cancerous changes that are not visible to the naked eye.
4. Biopsy
– What It Is: If the doctor suspects the mole might be cancerous, they will take a mole sample (a biopsy) to examine under a microscope. This is the only sure way to confirm if the mole is cancerous.
– Types of Biopsies:
– Shave Biopsy: The top layers of the mole are shaved off for examination.
– Punch Biopsy: A small, round piece of skin, including deeper layers, is removed.
– Excisional Biopsy: The entire mole and some surrounding skin are removed.
Why It’s Important: A biopsy helps the doctor examine the mole’s cells in detail and determine whether they are cancerous or benign.
5. Lab Analysis
– What Happens: The biopsy sample is sent to a pathology lab, where a pathologist (a doctor specializing in analyzing tissue) examines it under a microscope.
– What They Look For: The pathologist looks for abnormal cells, especially those that are fast-growing or show signs of becoming melanoma or other skin cancers.
6. Additional Testing (if Cancerous)
– What Happens: If the mole is cancerous, additional tests may be needed to check if the cancer has spread (metastasized). These tests may include:
– Lymph Node Biopsy: Checking nearby lymph nodes for cancer cells.
Imaging Tests: If there’s concern that cancer has spread to other body areas, scans like X-rays, CT, or MRI might be used.
– Why It’s Done: These tests help doctors understand the cancer’s stage and determine the best treatment plan.
Why Early Diagnosis is Crucial
Diagnosing a cancerous mole early is key to successful treatment. When melanoma is caught early (before it spreads), it is much easier to treat and has a higher chance of being cured. Periodic skin checks at home and with a dermatologist can help detect problems early and improve the outcome.
Cancerous Mole Treatment
1. Surgical Removal: The most standard treatment for a cancerous mole is surgical excision, which involves removing the mole along with some of the healthy skin around it to ensure all cancer cells are eliminated. The cost of surgical removal can vary widely, from about INR 20,000 to INR 1,00,000, depending on the complexity of the procedure.
2. Radiation Therapy: This treatment uses high-energy rays to kill cancer cells. It’s often used when surgery isn’t a choice or to destroy any remaining cancer cells post-surgery. The cost for radiation therapy sessions can range from INR 10,000 to INR 50,000 per session.
3. Immunotherapy: This is a newer form of treatment that boosts the body’s immune system to fight cancer. It’s particularly used for advanced skin cancers and can be more expensive than other treatments.
4. Targeted Therapy: These drugs target specific molecules in cancer growth, especially for advanced skin cancers. The costs for these therapies can vary, but they are generally considered expensive.
The average cost of skin cancer treatment in India, including melanoma, ranges from INR 2,50,000 to INR 5,00,000.
Conclusion
In conclusion, cancerous moles can be a severe health issue if not detected and treated early. Regular skin checks and knowing the signs of melanoma are key to catching it early. Treatment for cancerous moles can be expensive, especially in India, where the costs of surgery, therapy, and medications add up quickly. However, crowdfunding websites can provide a helpful solution. Platforms like these allow people to raise money from friends, family, and even strangers to help cover high medical expenses, ensuring that financial barriers don’t stand in the way of receiving proper care.
