Final answer:
Squamous cell carcinoma in-situ, characterized by a red, scaly patch on the skin, is an easily curable early form of skin cancer.
Step-by-step explanation:
True, an early form of skin cancer that is characterized by a red, scaly patch and is easily curable is called squamous cell carcinoma in-situ. Squamous cell carcinoma affects the keratinocytes of the stratum spinosum in the epidermis. It is commonly found on the scalp, ears, and hands and is the second most common skin cancer. Majority of squamous cell carcinomas are localized and have a low likelihood of metastasizing, making them generally curable through surgery and sometimes radiation. Early detection greatly increases the chance for successful treatment.
