Different things... Squamous cell skin cancer (scca) can take different appearances. In general the lesion will progressively enlarge. It is usually scaly and dry appearing and can have ulceration. It may bleed, esp. If picked at. It may be painless or itch. Early ones usually don't hurt. There are some benign skin lesions which mimic scca. Have any suspicious lesions examined and/or biopsied.
