Fluorouracil (5-FU) is a topical chemotherapy cream applied directly to the skin to target abnormal cells. It's generally used for precancerous lesions or very early, superficial skin cancers.

It works on the skin's surface, which is why it's typically suited for shallow lesions rather than deeper ones. For the inner ear area, this gets a bit more complex. The ear is considered a sensitive, high-risk location — similar to the nose, eyes, and lips — where preserving healthy tissue matters a lot.

Because of this, a dermatologist may lean toward options like Mohs surgery rather than topical treatments for that area. That said, every case is different and depends on:

- The size and depth of the lesion
- Whether it's precancerous or cancerous
- Your overall health and treatment preferences

The frequency of 5-FU application varies — it's typically applied once or twice daily for several weeks, but your doctor will tailor that to your specific situation.

Definitely worth having a detailed conversation with your dermatologist about whether 5-FU is appropriate for your specific location and lesion type. Regular follow-ups are also important to make sure the treatment is working.
