Do you think this could be skin cancer developing? Should I get it checked? (Photo)

If you have a suspicion or concern I'd always recommend an in-person office visit with a board-certified dermatologist, we can only judge so much from the photo. That being said, a long-standing red area on the nose can be benign (rosacea, hemangioma, spider angioma, post inflammatory hyperpigmentation, or a stubborn area of folliculitis). It can also be something that's not benign (a precancer called actinic keratosis, or a basal cell carcinoma which is a skin cancer would be at the top of my list based on the photo provided. Hope that helps some, best of luck!
