Is this skin cancer?

I’m 25F asian. I noticed 2 of my moles are getting bigger as years go by. One is located on my leg and the other on my arm. I’m getting worried it could be cancer. Please help. https://ibb.co/sZsHRLV https://ibb.co/HTbCGkvb https://ibb.co/xKzbXnSw https://ibb.co/5XDDJBC3 https://ibb.co/XxDnV0Gd
