Skin cancer is one of the most common types of cancer worldwide, and India has seen a rise in its incidence in recent years. It typically manifests in the form of growths or sores on the skin, and while it can be deadly if left untreated, early detection and modern treatments can lead to a high success rate in managing the condition. The treatment approach depends on the type, stage, and location of the skin cancer.
Symptoms of Skin Cancer
Skin cancer often presents as:
- New growths or lesions that appear on the skin
- Changes in existing moles or freckles (size, shape, or color)
- Itchy, bleeding, or crusting lesions
- Pain or tenderness in a specific skin area
Types of Skin Cancer
- Basal Cell Carcinoma (BCC): The most common form, usually occurring in areas exposed to the sun, like the face or neck.
- Squamous Cell Carcinoma (SCC): More aggressive than BCC, SCC can spread to other parts of the body.
- Melanoma: The deadliest form of skin cancer, often originating in melanocytes (cells responsible for skin pigment). It is most common in fair-skinned individuals.
Stages of Skin Cancer
The treatment plan varies significantly with the stage of cancer:
- Stage 0 (Carcinoma in situ): Localized cancer, confined to the outermost layer of skin.
- Stage I and II: Cancer is confined to the skin but may have spread to deeper layers.
- Stage III and IV: Cancer has spread to lymph nodes or other organs.
Key Comparisons:
- Aggression & Spread: Melanoma is the most aggressive and deadly, with a high chance of spreading quickly to other parts of the body. In comparison, BCC is the least aggressive and rarely spreads, while SCC is more aggressive than BCC and can spread to other tissues and organs.
- Prognosis: BCC has the best prognosis if treated early, with nearly 100% survival rates in localized cases. Melanoma’s prognosis is highly dependent on the stage at diagnosis. Early detection is crucial for survival. SCC’s prognosis is less favorable than BCC but better than melanoma if detected early.
- Treatment: While BCC and SCC are often treated with surgical excision, melanoma may require more aggressive treatments like immunotherapy and targeted therapy, especially in advanced stages.
- Recurrence: SCC and melanoma have higher recurrence rates, especially in advanced stages, whereas BCC has a lower recurrence rate if treated properly.
Each skin cancer type requires tailored treatment based on its aggressiveness, stage, and location, emphasizing the importance of early detection and appropriate medical intervention.
| Aspect | Basal Cell Carcinoma (BCC) | Squamous Cell Carcinoma (SCC) | Melanoma |
| Overview | The most common and least aggressive form of skin cancer. | More aggressive than BCC, can spread to other parts of the body. | The deadliest form of skin cancer, originating in melanocytes (pigment-producing cells), and can spread quickly if not treated. |
| Common Areas | Sun-exposed areas like the face, ears, neck, scalp, and shoulders. | Sun-exposed areas (especially face, ears, and hands), but also non-sun-exposed areas like genitals. | Often occurs on sun-exposed skin but can develop anywhere, including under the nails, on the palms, or in the eyes. |
| Growth Pattern | Slow-growing, rarely spreads beyond the skin. | Can grow quickly and invade deeper tissues; has a higher chance of spreading (metastasizing). | Can grow rapidly and spread to other parts of the body (metastasize). |
| Appearance | Pearly, translucent nodules, often with visible blood vessels; may have a central depression or ulceration. | Red, scaly patches, open sores, or elevated growths that may bleed or crust over. | Irregularly shaped, asymmetrical, multi-colored moles or spots, often with uneven borders. Can be larger than typical moles. |
| Symptoms | – Painless – Itchy or tender occasionally – Bleeding or crusting may occur if neglected | – Persistent sores that do not heal – Red, inflamed skin that may bleed or crust – Painful lesions in some cases | – Itching or tenderness – Bleeding or oozing lesions – Swollen lymph nodes – New or changing mole or freckle |
| Stages | Stage 0 (Carcinoma in situ): Confined to the outer skin layer. | Stage 0 (Carcinoma in situ): Cancer cells only in the outer skin layer. Stage I/II: Tumor confined to the skin or nearby tissues. Stage III/IV: Spread to lymph nodes or other organs. | Stage 0: In situ melanoma, confined to the top layer of skin. Stage I-IV: Tumor thickness and spread increase with later stages, spreading to lymph nodes and organs. |
| Treatment Options | – Surgical excision: Removal of the tumor. – Cryotherapy: Freezing the tumor. – Electrodesiccation and curettage: Scraping and burning the cancer cells. – Topical treatments: For small or superficial cases. | – Surgical excision: Wide excision to ensure clean margins. – Radiotherapy: For cases inoperable or if surgery isn’t an option. – Chemotherapy: Used for advanced SCC. – Immunotherapy: For more aggressive cases. | – Surgical excision: Wide excision for early-stage melanoma. – Immunotherapy: Pembrolizumab, nivolumab for advanced melanoma. – Targeted therapy: BRAF inhibitors for BRAF-positive melanoma. – Radiotherapy and chemotherapy: In advanced cases. |
| Prognosis | Very good prognosis if caught early, with nearly 100% survival rate in localized cases. Rarely spreads beyond the skin. | Prognosis can be favorable if detected early, but more aggressive forms of SCC can spread to other organs, reducing survival rate. | Prognosis depends on the stage at diagnosis. Early-stage melanoma has a high survival rate (up to 99%), but advanced melanoma has a low survival rate due to metastasis. |
| Risk Factors | – Fair skin – Sun exposure – Older age – Immunosuppression | – Fair skin – Sun exposure – Immunosuppression – Older age – HPV infection (for some SCC types) | – Fair skin – Family history of melanoma – History of excessive sun exposure – Having many moles or atypical moles – Genetic mutations (e.g., BRAF) |
| Recurrence Rate | Low recurrence if treated early; may recur locally in rare cases. | Higher recurrence rate compared to BCC, especially in advanced stages or untreated cases. | High recurrence rate, particularly in advanced stages or after metastasis. Requires diligent monitoring. |
| Advanced Treatment Options | Rarely requires advanced treatments unless there is recurrence or aggressive form. | Immunotherapy: For advanced SCC. Targeted therapy: For metastatic cases. Chemotherapy: In advanced stages. | Immunotherapy: Often used for advanced melanoma. Targeted therapy: For specific mutations like BRAF. Chemotherapy and Radiotherapy: For advanced cases. |
This table offers a side-by-side comparison of the main characteristics, types, treatments, and prognosis of Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC), and Melanoma.

- Targeted Therapy: A newer treatment that targets specific mutations within cancer cells, like BRAF inhibitors for melanoma.
- Chemotherapy: Used in advanced cases, particularly for melanoma or SCC.
- Recurrence and DFS (Disease-Free Survival) Rate
- Recurrence Rate: Skin cancer can recur, especially in aggressive forms like melanoma. The risk of recurrence increases with the stage of the cancer at the time of treatment. Proper follow-up is essential for managing recurrence.
- DFS: A high survival rate is typically achieved for early-stage skin cancers, with a good prognosis following primary treatments.
Immunotherapy and Mutations in Skin Cancer
In advanced skin cancers, particularly melanoma, immunotherapy has revolutionized treatment. Targeting genetic mutations, such as those in the BRAF gene, has shown significant improvement in outcomes. This personalized approach helps in providing treatment specific to the genetic makeup of the cancer, increasing the chances of successful management.
