Hi @vaniplaku, I’m glad you reached out. For your (and your dad’s) safety, we are unable to offer medical advice or diagnosis since we are not medical professionals. I would encourage you and your father to reach out to his doctor/ dermatologist so they can evaluate this spot. Anytime you notice a new, changing or worrisome spot it’s always best to have it checked as early detection is important. Please reach out if you have any further questions and if you’re comfortable, let us know how your dad is doing. We’ll be thinking of you. -Julie (team member)
