To diagnose skin cancer, Dr. Hiba Injibar will examine your skin for growths, moles and irregular dry patches. If she finds something that looks like skin cancer, it will be removed and sent to lab for biopsy. Skin cancer cannot be diagnosed without a biopsy. A biopsy is quick, safe and easy for a dermatologist to perform. The discomfort and risks are minimal and the whole procedure takes less than a minute.
