Weird skin lesions on my body that might be cancer? (Photos)

I'm a 24 year old Asian male. My skin has been super itchy lately which may be eczema because I placed mometasone on it and it went away, however, the ones below have not gone away nor have they inproved. The first picture the skin is raised slightly. I am scared it might be some sort of skin cancer? It's not bleeding of any sort nor does it improve with lotion. Should I be worried? I scheduled an appointment with a derm but the soonest date was February.
