Detailed answer

While most rashes are not indicative of skin cancer, certain types of skin rashes can be a warning sign. For example, a persistent rash that does not respond to treatment or gets worse over time may be a symptom of skin cancer. Other potential signs include a rash that has irregular borders, changes in color or texture, or a rash that bleeds easily. It is important to consult a dermatologist if you notice any suspicious rash or skin abnormality, as they can perform a thorough examination and recommend appropriate tests or treatments.
