Skin Cancer

Skin Cancer: Symptoms, Diagnosis and Treatment Options

Skin cancer develops when abnormal cells in the skin grow uncontrollably, often due to damage to the DNA of skin cells. It can affect different areas of the body, including the face, scalp, neck, arms, hands and other parts of the skin exposed to sunlight. Although some types of skin cancer grow slowly, others can spread to nearby tissues or distant organs if not identified and treated appropriately.

Understanding the early signs of skin cancer, recognising unusual changes in moles and seeking timely medical advice are important steps towards effective management. Skin cancer treatment depends on the cancer type, tumour size, location, stage and the patient's overall health.

At SirisHealthcare, patients can explore information about skin cancer diagnosis and treatment in India, understand available treatment approaches and find hospitals and specialists offering relevant cancer care services.

What Is Skin Cancer?

Skin cancer occurs when skin cells undergo abnormal changes and begin multiplying without normal control. Most cases are associated with ultraviolet (UV) radiation from sunlight or artificial sources such as tanning equipment. However, skin cancer can also develop in areas that receive little or no sun exposure.

There are several types of skin cancer, each with different characteristics, growth patterns and treatment requirements. The three most common types are basal cell carcinoma, squamous cell carcinoma and melanoma.

Early evaluation of suspicious skin changes can help doctors establish an accurate diagnosis and determine the appropriate treatment approach.

Types of Skin Cancer

Understanding the different types of skin cancer helps patients recognise why diagnosis and treatment plans can vary.

Basal Cell Carcinoma (BCC)

Basal cell carcinoma is the most common type of skin cancer. It develops in basal cells, which are found in the lower part of the epidermis, the outer layer of the skin.

It commonly appears on sun-exposed areas such as the face, nose, ears, neck and hands. Signs may include a pearly bump, a flat scaly patch, a sore that repeatedly heals and reopens, or a growth that bleeds easily.

Basal cell carcinoma usually grows slowly and rarely spreads to distant organs, but untreated lesions can damage surrounding skin and tissues.

Squamous Cell Carcinoma (SCC)

Squamous cell carcinoma develops in squamous cells that form much of the skin's outer layer. It frequently occurs on sun-exposed areas, although it can develop elsewhere.

Common warning signs include a persistent scaly patch, a firm red nodule, a rough growth or a sore that does not heal. Some cases can grow into deeper tissues and spread to other parts of the body.

Early medical assessment helps determine the extent of the condition and suitable treatment options.

Melanoma

Melanoma is a less common but potentially more aggressive type of skin cancer. It develops from melanocytes, the cells responsible for producing skin pigment.

Melanoma may develop in an existing mole or appear as a new unusual spot. It can occur anywhere on the body, including areas that receive limited sunlight.

Changes in the appearance of a mole should not be ignored. Early diagnosis and appropriate treatment are particularly important because melanoma can spread to other organs.

Early Signs and Symptoms of Skin Cancer

Recognising skin cancer symptoms can help patients seek medical attention before a suspicious lesion progresses.

Common warning signs include:

• A new growth, lump or unusual spot on the skin.
• A mole that changes in size, shape or colour.
• A sore that does not heal or repeatedly returns.
• A skin lesion that bleeds, crusts or becomes irritated.
• A rough or scaly patch that persists.
• A pearly, shiny or translucent bump.
• A dark spot with irregular borders or multiple colours.
• A growth that looks different from other moles on the body.

The ABCDE Rule for Identifying Suspicious Moles

The ABCDE rule is a useful guide for recognising changes that may require professional assessment.

• A – Asymmetry: One half of the mole looks different from the other.
• B – Border: The edges are irregular, uneven or poorly defined.
• C – Colour: The mole has multiple colours or uneven pigmentation.
• D – Diameter: The spot is often larger than 6 mm, although melanoma can be smaller.
• E – Evolving: The mole changes in size, shape, colour or appearance over time.

Not every unusual mole is cancerous, and some melanomas do not follow all these warning signs. A changing or suspicious lesion should be evaluated by a qualified medical professional.

Causes and Risk Factors of Skin Cancer

Skin cancer can develop due to a combination of environmental exposures, inherited factors and individual characteristics.

Important risk factors include:

Ultraviolet Radiation Exposure

Prolonged exposure to ultraviolet radiation from sunlight is a major risk factor for many skin cancers. Repeated sunburns, particularly during childhood, can also increase future risk.

Fair or Sun-Sensitive Skin

People with lighter skin, freckles, light-coloured eyes or skin that burns easily may have a higher risk of developing certain types of skin cancer. However, skin cancer can affect people of every skin tone.

Family History

A family history of melanoma or other skin cancers may increase an individual's risk, particularly when certain inherited genetic factors are involved.

Previous Skin Cancer

People who have previously been diagnosed with skin cancer may have a higher likelihood of developing another skin cancer.

Weakened Immune System

Individuals with weakened immune systems, including some organ transplant recipients and people receiving immunosuppressive medicines, may have an increased risk of developing certain skin cancers.

Age and Environmental Exposure

The risk of several skin cancers increases with age and cumulative UV exposure. However, skin cancer can also occur in younger individuals.

Skin Cancer Diagnosis and Tests

Accurate diagnosis is essential for determining the appropriate skin cancer treatment. Doctors generally begin with a detailed medical history and examination of the suspicious skin area.

Depending on the findings, additional investigations may be recommended.

Physical Skin Examination

A dermatologist or cancer specialist examines the suspicious lesion, including its size, shape, colour, texture and surrounding skin. Other areas of the body may also be examined for unusual changes.

Dermoscopy

Dermoscopy is a non-invasive examination technique that uses a specialised magnifying instrument to assess structures and patterns within a skin lesion. It can help identify features that may require further investigation.

Skin Biopsy

A skin biopsy is one of the most important diagnostic procedures for suspected skin cancer. It involves removing a small sample of skin tissue or, in some cases, the entire suspicious lesion for laboratory examination.

A pathologist examines the tissue under a microscope to determine whether cancer cells are present and identify the cancer type.

Imaging and Additional Tests

For selected patients, particularly when there is concern about advanced disease or spread to other areas, doctors may recommend imaging tests or additional investigations.

These may include ultrasound, CT scans, MRI or PET-CT, depending on the clinical situation and suspected cancer type.

Not every patient requires imaging. Investigations are selected according to the biopsy findings and individual medical assessment.

Skin Cancer Treatment Options

Skin cancer treatment in India depends on the type of cancer, its stage, location, size, depth and whether it has spread.

Doctors consider these factors before recommending a treatment plan. Available approaches may include surgery, topical medicines, radiation therapy and systemic cancer treatments.

Surgical Removal of Skin Cancer

Surgery is commonly used to treat many localised skin cancers. The procedure involves removing cancerous tissue, sometimes along with a margin of surrounding healthy skin.

The removed tissue may be examined to determine whether the cancer has been completely excised.

Mohs Surgery

Mohs micrographic surgery is a specialised technique used for selected skin cancers, particularly those occurring in cosmetically or functionally sensitive areas.

The surgeon removes cancerous tissue in stages and examines each layer microscopically until no cancer cells are identified in the examined margins.

It is particularly useful in selected cases of basal cell carcinoma and squamous cell carcinoma.

Cryotherapy

Cryotherapy uses extreme cold, commonly liquid nitrogen, to destroy certain superficial or selected precancerous skin lesions.

Its suitability depends on the lesion's diagnosis, depth and clinical characteristics. It is not appropriate for every type of skin cancer.

Topical Medicines

Certain prescription creams may be used for selected superficial skin cancers or precancerous lesions.

The choice of medicine depends on the diagnosis and extent of the condition. Topical treatment should only be used under medical supervision.

Radiation Therapy

Radiation therapy uses high-energy radiation to destroy cancer cells. It may be recommended for selected patients who are not suitable for surgery, have specific tumour characteristics or require additional treatment after surgery.

Immunotherapy and Targeted Therapy

For certain advanced or high-risk skin cancers, particularly melanoma, systemic treatments may be considered.

Immunotherapy helps the immune system recognise and attack cancer cells. Targeted therapy may be appropriate when specific genetic changes are identified in the tumour.

The treating oncologist determines whether these approaches are suitable based on pathology, molecular testing and the patient's overall health.

What to Expect During Skin Cancer Treatment

The treatment journey generally involves several stages, although the process differs depending on the diagnosis.

1. Initial Consultation: A dermatologist or oncologist reviews the patient's symptoms, medical history and suspicious skin changes.

2. Diagnostic Evaluation: The doctor may recommend dermoscopy, a skin biopsy or additional investigations to confirm the diagnosis.

3. Treatment Planning: The medical team reviews the results and discusses suitable treatment options, possible risks and expected recovery.

4. Treatment Procedure: Depending on the diagnosis, treatment may involve surgery, topical medicines, radiation therapy or systemic cancer treatment.

5. Recovery and Follow-Up: Patients receive guidance on wound care, recovery, skin monitoring and follow-up appointments.

Patients should discuss any concerns about treatment, cosmetic effects, possible complications and long-term monitoring with their treating specialist.

Recovery and Follow-Up Care

Recovery after skin cancer treatment depends on the procedure performed, the cancer type and the individual's health.

After minor skin surgery, patients may need wound care, dressing changes and temporary activity adjustments. More extensive procedures may require longer recovery and additional medical support.

Follow-up appointments help doctors monitor healing, assess treatment response and identify possible recurrence or new skin lesions.

People with a history of skin cancer may benefit from regular professional skin examinations and periodic self-checks as advised by their doctor.

How to Reduce the Risk of Skin Cancer

Although not all skin cancers can be prevented, certain precautions can help reduce UV exposure and lower the risk of developing some types of skin cancer.

• Apply broad-spectrum sunscreen with SPF 30 or higher to exposed skin.
• Reapply sunscreen approximately every two hours when outdoors and after swimming or sweating.
• Wear protective clothing, sunglasses and a wide-brimmed hat.
• Seek shade during periods of strong sunlight.
• Avoid artificial tanning equipment.
• Examine your skin regularly for new or changing spots.
• Seek medical advice for persistent or unusual skin lesions.
• Follow recommended skin examination schedules if you have a history of skin cancer.

People with previous skin cancer, multiple atypical moles or a strong family history should discuss an appropriate monitoring plan with a specialist.

When Should You Consult a Skin Cancer Specialist?

Do not delay medical evaluation if you notice a suspicious or changing skin lesion.

Consider consulting a dermatologist or oncologist if you experience:

• A mole that changes in colour, shape or size.
• A persistent sore that does not heal.
• An unusual skin growth that bleeds repeatedly.
• A rapidly growing lump or lesion.
• A dark spot with irregular borders or multiple colours.
• A skin lesion that becomes painful, itchy or crusted.
• A previously treated area showing new changes.

A suspicious lesion does not automatically mean cancer. However, timely examination and appropriate testing can help establish the cause and avoid unnecessary delays in care.

Frequently Asked Questions About Skin Cancer

1. What are the first signs of skin cancer?

Early signs can include a new skin growth, a changing mole, a persistent sore, an unusual dark spot or a rough patch that does not heal. Changes in size, shape, colour or texture should be professionally assessed.

2. Is skin cancer curable?

Many skin cancers, particularly those identified at an early stage, can be treated successfully. Outcomes depend on the cancer type, stage, location and individual health factors. Advanced cancers may require more complex treatment.

3. What are the three main types of skin cancer?

The three main types are basal cell carcinoma, squamous cell carcinoma and melanoma. They differ in their origin, growth behaviour, risk of spreading and treatment requirements.

4. How is skin cancer diagnosed?

Diagnosis usually begins with a physical examination of the skin. A dermoscopic examination and skin biopsy may be recommended. Additional imaging or laboratory tests may be needed in selected cases.

5. What is the best treatment for skin cancer?

There is no single treatment suitable for every patient. Surgical removal, Mohs surgery, topical medicines, radiation therapy, immunotherapy and targeted therapy may be considered depending on the diagnosis and stage.

6. Can skin cancer develop in people with darker skin?

Yes. Skin cancer can affect people of all skin tones. In people with darker skin, some melanomas may occur on the palms, soles or beneath the nails. Unusual or changing lesions should be evaluated regardless of skin colour.

7. Does every unusual mole indicate skin cancer?

No. Most moles are benign. However, a mole that changes in size, shape, colour or appearance should be examined by a qualified specialist.

8. How long does recovery from skin cancer surgery take?

Recovery varies depending on the size and location of the lesion, the surgical technique and the individual's healing process. Minor procedures may heal within a few weeks, while more extensive surgery may require additional recovery time.

9. Can skin cancer spread to other parts of the body?

Some skin cancers can spread beyond the original site. Melanoma has a greater tendency to spread than most basal cell carcinomas. Certain squamous cell carcinomas can also spread, particularly when high-risk features are present.

10. How can I find a hospital for skin cancer treatment in India?
