Basal cell carcinoma is a slow-growing skin cancer that accounts for 90% of skin cancers and typically occurs in sun-exposed areas like the face, shoulders, neck, hands, and back. While it is relatively superficial, topical treatments for basal cell carcinoma using apple cider vinegar can be effective, such as securing an apple cider vinegar-moistened gauze pad over the basal cell with tape and reapplying the vinegar several times per day, resulting in healing within 5 weeks at a cost of less than $10.
