This is a really good question. Many a times, different kinds of skin problems can present in very similar ways.
The best and safest way to get the diagnosis right is to see a doctor as soon as possible to get it assessed physically. You can see a general practitioner, a dermatologist or an aesthetic doctor depending on your preference. A skin biopsy may be required.
I do not recommend getting advice or answer over the internet over this matter because basal cell carcinoma can be a serious condition if not discovered early.
Thank you.
