You notice a new mole that seems darker than the others or a small sore on your nose that never heals. Perhaps you’ve spotted a rough, scaly patch that keeps returning despite your best efforts to care for it. While many skin changes are harmless, others can be early signs of skin cancer. Knowing what to look for can make all the difference in safeguarding your health.
Early detection allows skin cancer to be diagnosed and treated before it has the opportunity to grow or spread. At Curated Dermatology in Bridgewater, NJ, board-certified dermatologist Dr. Tanvi Patel takes a highly personalized, patient-centered approach to diagnosing and treating skin cancers. Understanding the differences between melanoma, basal cell carcinoma, and squamous cell carcinoma can help you recognize when it’s time to seek expert evaluation.
Melanoma
Melanoma develops from melanocytes, the pigment-producing cells that give your skin its color. Although it is less common than other forms of skin cancer, melanoma is considered the most aggressive because it has a greater ability to invade deeper tissues and spread to other parts of the body. It may develop within an existing mole or appear as a new spot. Because early-stage melanoma is highly treatable, seeking prompt evaluation is essential.
Key signs and symptoms of melanoma:
- A mole that changes in size, shape, or color
- Irregular or poorly defined borders
- Multiple shades of brown, black, red, or blue within one lesion
- A spot that differs noticeably from surrounding moles
- Itching, bleeding, crusting, or tenderness
Treatment and prognosis
Treatment depends on how early the melanoma is diagnosed but often begins with surgical removal of the cancer. More advanced cases may require additional therapies. When detected in its earliest stages, melanoma has an excellent prognosis, making routine skin examinations and prompt evaluation of changing lesions especially important.
Basal cell carcinoma (BCC)
Basal cell carcinoma is the most common type of skin cancer. It begins in the basal cells located in the deepest portion of the epidermis and often develops after years of sun exposure. Basal cell carcinoma most often appears on the face, scalp, ears, neck, shoulders, or other frequently exposed areas. It generally grows slowly and rarely spreads to distant parts of the body, but without treatment it can gradually invade nearby skin and underlying tissues.
Key signs and symptoms of basal cell carcinoma:
- A pearly or translucent bump
- A sore that repeatedly heals and returns
- A pink or flesh-colored patch
- Visible tiny blood vessels across the lesion
- A scar-like area that gradually enlarges
Treatment and prognosis
Most basal cell carcinomas can be treated successfully when diagnosed early. Depending on the size, location, and characteristics of the lesion, treatment may include surgical excision or Mohs surgery to precisely remove the cancer while preserving as much healthy tissue as possible. Early treatment offers an excellent prognosis and helps minimize tissue damage.
Squamous cell carcinoma (SCC)
Squamous cell carcinoma arises from the squamous cells that make up the outer portion of the epidermis. Like basal cell carcinoma, it is often associated with long-term ultraviolet exposure and commonly develops on sun-exposed skin. It may also arise from precancerous lesions or develop within chronic scars or wounds. Compared with BCC, squamous cell carcinoma has a greater likelihood of growing into deeper tissues or spreading if treatment is delayed.
Key signs and symptoms of squamous cell carcinoma:
- A rough, scaly red patch
- A thickened or crusted growth
- A persistent sore that does not heal
- A wart-like lesion
- Tenderness, bleeding, or recurring crusting
Treatment and prognosis
Squamous cell carcinoma is highly treatable when identified early. Treatment often involves surgical removal, with Mohs surgery frequently recommended for cancers in cosmetically or functionally important areas. Prompt diagnosis and treatment significantly reduce the risk of deeper invasion and improve long-term outcomes.
