Skin Cancer Symptoms & Treatment

You’ve noticed a new spot, a changing mole, or a sore that won’t heal. Could it be skin cancer? This guide explains the common symptoms, when to see a dermatologist, and what treatment typically involves — so you can take informed action without panic. Most skin changes are harmless, but early detection saves lives.

What Are the Main Types of Skin Cancer?

Skin cancer begins when skin cells grow abnormally, usually due to damage from ultraviolet (UV) radiation. The three most common types are:

• Basal cell carcinoma (BCC) – the most common form. It grows slowly and rarely spreads to other parts of the body.
• Squamous cell carcinoma (SCC) – also common, it can spread if not treated early but is generally less aggressive than melanoma.
• Melanoma – the most dangerous type. It develops in melanocytes (pigment-producing cells) and can spread quickly to lymph nodes and organs if caught late.

BCC and SCC are often grouped as non-melanoma skin cancers. Understanding which type you may be dealing with helps doctors decide the right treatment. Only a biopsy can confirm the diagnosis.

How to Spot Skin Cancer: The ABCDE Rule and Other Warning Signs

The ABCDE rule is a simple way to remember melanoma warning signs. Check your moles and spots regularly — especially if you have a history of sun exposure or a family history of skin cancer.

• A – Asymmetry: One half of the mole doesn’t match the other half.
• B – Border: Edges are irregular, ragged, or blurred.
• C – Color: Multiple shades of brown, black, blue, red, or white within one spot.
• D – Diameter: Larger than 6 mm (about the size of a pencil eraser), though melanomas can be smaller.
• E – Evolving: Any change in size, shape, color, or symptom (itching, bleeding, crusting).

Other warning signs include a sore that does not heal within two weeks, a shiny or pearly bump, a flat scaly patch that bleeds, or a persistent rough spot on the lip or ear. The table below helps you compare symptoms of the three main types.

Type	Typical Appearance	Common Location	Growth Rate	Risk of Spread
Basal cell carcinoma	Pearl-like bump, pink or flesh-colored, sometimes with visible blood vessels	Face, ears, neck, scalp (sun-exposed areas)	Slow (months to years)	Very low; rarely spreads
Squamous cell carcinoma	Red, scaly patch, firm nodule, or sore that crusts or bleeds	Ears, lower lip, back of hands (sun-exposed areas)	Moderate (weeks to months)	Low to moderate; can spread if neglected
Melanoma	Irregular, dark brown or black spot that may have multiple colors; can arise from normal skin or a mole	Back, legs (men on trunk, women on legs); also palms, soles, under nails	Variable; can be rapid	High; spreads to lymph nodes and organs

Remember: not every bump or spot is cancer. But if you notice any of these features, see a dermatologist for evaluation.

When Should You See a Dermatologist?

Make an appointment with a dermatologist if you have any of the following:

• A mole or spot that changes in size, shape, or color
• A sore that does not heal within two weeks
• New growth that looks unusual or feels itchy, tender, or bleeds
• A spot with irregular borders or multiple colors
• A family history of skin cancer or a personal history of severe sunburns

Many Bangladeshi patients delay visiting a doctor due to cost concerns or fear of diagnosis. However, the vast majority of suspicious lesions turn out to be benign (non-cancerous). Even if it is cancer, early detection makes treatment simpler and far more effective. A quick check with a dermatologist — often using a handheld magnifying tool called a dermoscope — costs little and can save your life.

How Is Skin Cancer Diagnosed?

A dermatologist will first examine your skin with a dermoscope — a special magnifying lens that reveals structures invisible to the naked eye. If a spot looks suspicious, the doctor will perform a biopsy. This involves numbing the area with local anaesthetic and removing a small piece of the lesion (or the entire lesion) for examination under a microscope.

Biopsy is the only way to confirm whether a growth is cancer and what type it is. The procedure is quick, usually causes minimal discomfort, and leaves a tiny scar. Results typically come back within a week. Do not rely on home photos or online diagnosis — only a trained pathologist can give you a definitive answer.

What Are the Treatment Options for Skin Cancer?

Treatment depends on the type, size, location, and stage of the cancer. The goal is to remove or destroy all cancer cells while preserving as much healthy tissue as possible. Common treatments available in Bangladesh include:

• Surgical excision: The tumour and a small margin of surrounding skin are cut out under local anaesthesia. This is the standard treatment for most BCC, SCC, and early melanomas.
• Mohs surgery: A precise technique where the surgeon removes thin layers of skin one at a time and examines them immediately. It spares healthy tissue and is ideal for facial cancers. Available at some specialised centres in Dhaka.
• Cryotherapy: Freezing the lesion with liquid nitrogen, suitable for very early BCC or SCC.
• Topical chemotherapy: Creams containing 5-fluorouracil or imiquimod can treat superficial BCC or SCC.
• Radiation therapy: Used when surgery is not possible or for advanced disease; also for cosmetic reasons on the face.
• Immunotherapy and targeted therapy: For advanced melanoma that has spread. These drugs are expensive but increasingly available in Bangladesh.

Your doctor will recommend the best option after a full evaluation. Treatment is curative in the vast majority of cases when caught early.

Skin Cancer in Bangladesh: What You Should Know

Although darker skin naturally has more melanin (which provides some UV protection), people with brown or black skin still develop skin cancer. In Bangladesh, the main risk factor is chronic, cumulative sun exposure — especially among farmers, rickshaw pullers, construction workers, and others who work outdoors. Melanoma can also occur on palms, soles, and under nails (acral melanoma), which is more common in non-white populations.

Delayed diagnosis is a real problem. Many people ignore a changing mole or a non-healing sore until it becomes painful or bleeds frequently. Fear of treatment cost and social stigma around cancer also keep patients away from doctors. The truth is: an early visit to a dermatologist is far less expensive and traumatic than treating advanced disease. Regular self-checks and annual skin screening (especially for high-risk individuals) can make a life-saving difference.

Frequently Asked Questions

Can people with darker skin get skin cancer?

Yes. While skin cancer is more common in people with fair skin, it can also occur in individuals with darker skin tones. In fact, skin cancer in darker skin is often diagnosed at a later stage, which can make treatment more challenging. Pay attention to any new or changing mole, especially on areas like the palms, soles, nails, or inside the mouth, as these are common sites in darker skin. Regular self-examination and dermatologist visits are equally important regardless of skin colour.

Are all skin cancers life-threatening?

No. The most common types—basal cell carcinoma and squamous cell carcinoma—are usually slow-growing and highly treatable when caught early. They rarely spread to other parts of the body. However, melanoma, though less common, is more aggressive and can become life-threatening if not treated promptly. That’s why any suspicious skin change should be evaluated by a dermatologist. Early detection dramatically improves outcomes for all types.

What happens if I ignore a suspicious spot for several months?

Delaying evaluation may allow a skin cancer to grow deeper, potentially requiring more extensive surgery or additional treatments like radiation. For melanoma, even a few months can make the difference between a stage where excision alone is curative and a stage where the cancer has spread to lymph nodes or other organs. It is always safer to have any concerning spot checked by a qualified dermatologist sooner rather than later.

Can home remedies or over-the-counter creams treat skin cancer?

No. There is no proven home remedy or over-the‑counter cream that can cure skin cancer. Some products may temporarily reduce the appearance of a lesion, but they do not remove the cancerous cells. Using them can delay proper diagnosis and treatment, allowing the cancer to progress. Only medically supervised treatments—such as surgical removal, cryotherapy, topical chemotherapy, or radiation—are effective. Always consult a doctor before trying any product on a suspicious skin spot.

How often should I have my skin checked after completing treatment?

Follow-up schedules depend on the type and stage of skin cancer, as well as your individual risk factors. For most non‑melanoma skin cancers, a dermatologist may recommend a full‑skin check every 6 to 12 months. For melanoma, more frequent visits (every 3 to 6 months initially) are common. Your doctor will advise a personalised plan. In between appointments, perform monthly self-examinations using the ABCDE rule and report any new or changing spots promptly.
