It’s the only way to know whether you have skin cancer. There’s no other way to know for sure. What your dermatologist removes will be looked at under a microscope. The doctor who examines the removed skin will look for cancer cells.
Can a dermatologist diagnose skin cancer by looking at it?
Having a skin biopsy is the only way to know for sure whether you have any type of skin cancer. After your dermatologist removes the spot, a doctor, such as your dermatologist or a dermatopathologist, will examine it under a high-powered microscope. The doctor is looking for cancer cells.
How do doctors know if you have skin cancer?
Remove a sample of suspicious skin for testing (skin biopsy). Your doctor may remove the suspicious-looking skin for lab testing. A biopsy can determine whether you have skin cancer and, if so, what type of skin cancer you have.

Unfortunately, you can’t tell by looking at a mole whether it’s cancerous or what type it is. It could very well be a normal skin spot with an abnormal appearance. A dermatologist can’t always tell the difference either.
How may a doctor determine the extent of skin cancer?
Because non-melanoma skin cancer rarely spreads, a biopsy is often the only test needed to diagnose and find out the stage, or extent, of cancer. A biopsy is the removal of a small amount of tissue for examination under a microscope.
What does Stage 1 melanoma look like?

Should I get checked for skin cancer?
Skin cancer screenings are recommended for adults at increased risk. They may be done by a primary care physician or a dermatologist. “Being at increased risk doesn’t mean you’ll get skin cancer, but you may need to start regular screenings in case you do get skin cancer and it can be caught early,” Dr. Kelley says.
What is considered early detection of skin cancer?
The key warning signs are a new growth, a spot or bump that’s getting larger over time, or a sore that doesn’t heal within a few weeks. (See Signs and Symptoms of Basal and Squamous Cell Skin Cancer for a more detailed description of what to look for.)
Can you feel skin cancer?

Does melanoma show up in routine blood work?
Blood tests aren’t used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
How does a dermatologist check a mole?
How does a dermatologist determine if moles are a concern? Normal (benign) skin moles do not need to be removed (doing so will leave a scar). If your dermatologist determines that the mole is a concern, he or she will perform a skin biopsy, in which a small sample of the mole is taken to examine under a microscope.
Can you have stage 4 melanoma and not know it?
When stage 4 melanoma is diagnosed after a scan, there may be no symptoms at all, and it can be difficult to believe the cancer has spread. However, people with stage 4 melanoma may have a very wide range of symptoms. People who have melanoma diagnosed in the brain are told not to drive.
Can you have melanoma for years and not know?
How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.
