Your doctor may refer you to a dermatologist who specializes in skin conditions. They will:
- Ask about your medical history
- Ask about your history of severe sunburns or indoor tanning
- Ask if you have any pain or other symptoms
- Ask when the spot first appeared
- Give you a physical exam to check the size, shape, color, and texture of the spot

sun exposure before age 15
skin color other than brown or black
freckles and moles a history of skin cancer
exposure to ultraviolet light or ionizing radiation
dysfunction, injury or infection of the immune system
multiple moles or freckles
a family history of melanoma skin cancer
albinism a family history of skin cancer

What Is Skin Cancer
Skin cancer is a serious but common skin condition that causes skin cells to replicate in irregular ways or damages the structure of the cells themselves. While there are many different causes of skin cancer, exposure to the suns ultraviolet rays is the most common underlying cause of all forms of skin cancer. When damaged skin cells multiply, they form tumors. These growths can be either benign or malignant. Benign tumors are typically considered noncancerous or precancerous. Malignant tumors are more likely to impact surrounding cells or metastasize, which means they may spread to other parts of the body.
There are many different types of skin precancers and cancers. Skin precancers include actinic keratosis and dysplastic nevi . The four most common skin cancers are basal cell carcinomas, squamous cell carcinomas, melanoma skin cancers, and merkel cell skin cancers. Most skin cancers are either basal or squamous cell carcinomas. While melanomas and merkel cell skin cancers make up a small percentage of cases, they cause the greatest number of skin cancer-related deaths each year as these types are more likely to metastasize.
Signs of skin cancer can be more easily remembered by the mnemonic ABCDEF. This was developed initially for melanoma detection, but it can be applied to most skin cancers:
A asymmetry the shape isnt uniform throughout
D diameter is the spot greater than the size of a pencil eraser? Is the diameter growing?

Though its an uncommon skin cancer, cases of Merkel cell carcinoma have increased rapidly in the last couple of decades.
This type of cancer starts when cells in the skin, called Merkel cells, start to grow out of control.
Merkel cell carcinomas typically grow quickly and can be difficult to treat if they spread.
They can start anywhere on the body, but Merkel cell carcinomas commonly affect areas exposed to the sun, such as the face, neck, and arms.
They may look like pink, red, or purple lumps that are firm when you touch them. Sometimes, they can open up as ulcers or sores.

Are All Moles Cancerous
Most moles are not cancerous. Some moles are present at birth, others develop up to about age 40. Most adults have between 10 and 40 moles.
In rare cases, a mole can turn into melanoma. If you have more than 50 moles, you have an increased chance of developing melanoma.
A note from Cleveland Clinic
Your skin is the largest organ in your body. It needs as much attention as any other health concern. What may seem like an innocent cosmetic imperfection, may not be. Performing regular skin self-checks is important for everyone and is especially important if you are a person at increased risk of skin cancer. Skin cancer is also color-blind. If you are a person of color, skin cancer can happen to you. Check your skin every month for any changes in skin spots or any new skin growths. Consider taking skin selfies so you can easily see if spots change over time. If youre a person of color, be sure to check areas more prone to cancer development, such as the palms of your hands, soles of your feet, between your toes, your genital area and under your nails. Takes steps to protect your skin. Always wear sunscreen with SPF of at least 30 every day of the year. Wear UV-A/UV-B protective sunglasses, wide-brimmed hats and long-sleeve shirts and pants. See your dermatologist at least once a year for a professional skin check.

What Causes Skin Cancer
UV rays are a major cause of all skin cancers. Too much exposure to UV rays from either the sun, or from indoor tanning devices like beds, booths, and lamps penetrates the skin, causing the skin to make more melanin, which turns skin dark or red. Any change in skin color after UV exposure is a sign of injury, not health.
Up to 90% of melanomas are estimated to be caused by UV exposure. Melanoma is the deadliest form of skin cancer and is on the rise in New York State. UV exposure can also cause cataracts and cancers of the eye .
Even if a sunburn or tan fades, the damage caused by that tan or burn does not, and the effects cannot be reversed. Most of a persons lifetime skin damage occurs before the age of 18 years. Skin damage adds up with each sunburn or tan and may one day result in skin cancer.

What Are The Risk Factors For Skin Cancer
About 90% of skin cancers are caused by UV rays, but there are other factors that can determine your risk. Some of these factors are:
- Your complexion: Fair-skinned people have less melanin in their skin and therefore less protection against the suns damaging UV rays.
- Number of moles: The risk is greater for people with 50 or more moles.
- Tanning bed use: People are more likely to develop skin cancer from using tanning beds than developing lung cancer from smoking. Their use causes a 75 percent increase in melanoma risk when indoor tanning beds have been used before age 30.
- Family history: Having a family member with skin cancer means you are at greater risk. The risk is especially strong if a close relative, such as a parent, sibling, or child, has skin cancer.
- History of sunburn: People who have had one or more severe, blistering sunburns as a child or teenager have an increased risk for melanoma. Sunburns in adulthood are also a risk factor for melanoma.
- History of skin cancer: Once youve had one skin cancer, your risks for developing another increases.

Common areas are head, neck, hands, and forearms. Many patients are not diagnosed until later in life because this condition develops over time as sun exposure continues.
Basal Cell Carcinoma Basal cell carcinomas are the most common form of skin cancer. These flesh colored bumps or pink patches of skin usually form on the head, neck and arms, but can be found anywhere on the body.

Warning Signs Of Melanoma The Most Deadly Form Of Skin Cancer
Even with all the incredible advancements of medical technology and research, cancer remains one of the leading problems of modern health. Melanoma is one of the most common types of skin cancer and is the most dangerous, especially when victims overlook the early symptoms.
It is accountable for more than ¾ of all skin cancer related deaths. More than 76,000 cases are expected to develop in the United States in the following year alongside almost 10,000 melanoma related deaths. Melanoma rates have consistently risen in previous years, but learning how to spot it early can save your life.
The Risks The Causes What You Can Do
Skin cancers like melanoma have damaged DNA in skin cells that lead to uncontrolled growth of these cells. Ultraviolet rays from the sun or tanning beds damage DNA in your skin cells. Your immune system repairs some of this damage but not all. Over time, the remaining DNA damage can lead to mutations that cause skin cancer. Many other factors also play a role in increasing the risk for melanoma, including genetics , skin type or color, hair color, freckling and number of moles on the body.
Understanding what causes melanoma and whether youre at high risk of developing the disease can help you prevent it or detect it early when it is easiest to treat and cure.
These factors increase your melanoma risk:
- Unprotected or excessive UV exposure from the sun or indoor tanning.
- Weakened immune system due to a medical condition or medications.
- Many moles: The more moles you have on your body, the higher your risk for melanoma. Also, having large moles , or any atypical moles, increases the risk for melanoma.
- Fair skin: Melanoma occurs more frequently in people with fair skin, light eyes and light or red hair.
- Skin cancer history: People who have already had melanoma or nonmelanoma skin cancers run a greater risk of developing melanoma in the future.
- Genetics: Melanoma can run in families one in every 10 patients has a family member who also has had the disease.

How Often Does Bcc Spread
Metastasis is rare with BCC, occurring in between 0.0028 and 0.55% of all cases. When it does occur, the lymph nodes, lungs, and bone are the most common sites of metastasis.
If BCC remains localized, there is a five-year survival rate of 100%. If BCC metastasizes, the outcomes are generally poor with median survival times ranging from eight months to 3.5 years.
