So I had mole down there . May be from many years may be like 10 years. Last time I checked it looked nice round or oval shape. Since it's covered with hair I dint see later. Today I felt like it's shape or size changed. My dad diagnosed stage 4 stomach cancer hence my worry. My mom and me have lot of moles around our body. This one is little bigger mole diffrent one. Should I show it dermatologist or oncologist?? I have attached image for reference. It is 0.7 cm.
