Skin cancer can take many forms, and anything that looks different, unusual, or new on your skin could potentially be skin cancer. Sometimes, it may appear as something noticeably different from the rest of your skin, often referred to as the "ugly duckling sign." However, in many cases, skin cancer can resemble an ordinary mole or spot on your skin, making it more challenging to identify.

Melanomas are often thought of as dark or pigmented lesions, resembling moles, freckles, or nevi on sun-exposed areas of the skin. However, they can also appear in places with minimal sun exposure, such as between your toes, on your scalp, or even inside your mouth. While most melanomas are pigmented, some are not. These non-pigmented melanomas, known as amelanotic melanomas, can present as pink or skin-colored lesions. Interestingly, these are among the fastest-growing and most life-threatening types of melanomas.

Squamous cell carcinomas (SCCs) and basal cell carcinomas (BCCs) often appear as sores or non-healing ulcers or lesions. At times, they can also be painful and prone to bleeding, making them important to identify and treat early.

It’s important to understand that the appearance of skin cancer can vary widely depending on the person, the location on the body, and the stage of the lesion's growth. To stay on the safe side, if you notice anything unusual, new, or concerning on your skin, make sure to get it checked by a professional.

Diagnosing skin cancer starts with a careful physical examination, which means looking at and feeling the lesion. While some skin cancers can be tricky to identify, most look suspicious enough at first glance to catch a trained eye.Multiple tools are utilised for accurate early diagnosis of skin cancer.
