Types of skin cancer
- Basal cell carcinoma: the most common type. It grows slowly and rarely spreads, but it can damage nearby tissue if left untreated.
- Squamous cell carcinoma: the second most common type. It often appears on sun-exposed skin and can spread if not treated.
- Melanoma: less common but the most dangerous type, because it can spread to other organs. Early detection is critical.

Diagnosis and treatment
If a spot looks suspicious, Dr. Fatteh performs a quick in-office biopsy and sends the sample to a lab. Treatment depends on the type, size and location of the cancer and may include:
- Surgical excision
- Electrodesiccation and curettage
- Cryotherapy for some precancerous spots (actinic keratoses)
- Prescription topical treatment for some superficial cancers and precancers
- Referral for Mohs surgery or oncology care when that is the best option
Frequently asked questions
How often should I get a skin check?
Most adults with risk factors benefit from a yearly full-body skin exam. People with a history of skin cancer may need checks more often.
Does a biopsy hurt?
The area is numbed first, so most people feel only a brief pinch. The procedure takes a few minutes.
