Have A Skin Cancer Screening
Early intervention and treatment is crucial in skin cancer cases. A yearly skin cancer screening with a dermatologist is the best way to detect skin cancer early, since dermatologists are trained to recognize the earliest warning signs.
If a suspicious growth or lesion is found during your screening, it will be biopsied to test for signs of cancer. If the biopsy comes back negative, no follow-up is necessary. If the biopsy comes back positive, your dermatologist will explain your treatment options and help you develop a clear plan for addressing the cancer.
The 2 Main Types Of Non
Melanoma is the leading cause of death among skin cancer types, so it’s understandable that it has become a major focus of the healthcare community. Non-melanoma skin cancers account for over 90 percent of all skin cancers in the United States, and while they are usually more easily managed, they can pose a serious problem if left unchecked.
The distinction between melanoma and non-melanoma skin cancer is important to discuss, as prognosis and management are different for each. Melanoma typically requires targeted therapy or immunotherapy, whereas surgical resection and chemotherapy are more common approaches for non-melanoma skin cancer. Newer, targeted therapy approaches have also emerged for non-melanoma skin cancers.
What follows is an overview of the two most common types of non-melanoma skin cancer: basal cell carcinoma and squamous cell carcinoma.
Basal Cell Carcinoma
Basal cell carcinoma originates from cells called keratinocytes. When these cells become cancerous, they may form a localized lesion. The lesion usually appears hard and slightly raised, often with a pearly color and some vascular markings. If a patient presents a lesion of this kind, a biopsy should be performed to confirm the diagnosis.
It should be noted that, even with successful treatment, a case of basal cell carcinoma leaves one at a higher risk for further skin cancers. It is recommended to have regular medical checkups to monitor the condition of your skin.

Merkel Cell Carcinoma: A Rare Skin Cancer On The Rise
Merkel cell carcinoma is a rare type of skin cancer that affects about 2,000 people in the United States each year.
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.
Risk factors include:
Skin Cancer Pictures By Type
Skin cancer is the most common form of cancer. There are several different types of skin cancer with Basal Cell Carcinoma, Squamous Cell Carcinoma, Bowens Disease, Keratoacanthoma, Actinic Keratosis and Melanoma most commonly occurring.
Basal cell carcinoma is the most common form of skin cancer, and least dangerous whereas melanoma is the most dangerous type.
Below you will find skin cancer pictures of these six types, but remember that skin cancer should be diagnosed by a doctor. Comparing your skin lesion to skin cancer images found online cannot replace medical examination.
If you have any pigmented mole or non-pigmented mark on your skin that looks different from the other marks or moles on your skin, that is new or that has undergone change, is bleeding or wont heal, is itching or in any way just seems off, visit your doctor without delay dont lose time comparing your mole or mark with various pictures of skin cancer.
If you want to be proactive about your health, you may want to photograph areas of your skin routinely including individual moles or marks to familiarise yourself with the appearance of your skin . A skin monitoring app may be a useful tool to assist in that process.

Different Types Of Cancer Start In The Skin
Skin cancer may form in basal cells or squamous cells. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer. They are also called nonmelanoma skin cancer. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.
Melanoma is less common than basal cell carcinoma or squamous cell carcinoma. It is more likely to invade nearby tissues and spread to other parts of the body.
This summary is about basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis. See the following PDQ summaries for information on melanoma and other kinds of cancer that affect the skin:
Basal Cell Carcinoma Pictures
Basal cell carcinoma usually appears in areas of the skin previously exposed to high levels of UV radiation such as the head, neck, ears and the back of the arms and hands. It is common in exposed skin of outdoor workers or people who have used sun tanning beds in the past.
As the basal cell carcinoma pictures below indicate, this type of skin cancer usually shows as a fleshy coloured bump that does not disappear over time and tends to grow slowly in size, eventually breaking down and ulcerating.
Below are pictures of skin cancer on the neck, face and trunk . These images show common areas where basal cell carcinoma develops, but it can develop anywhere.

Precancerous Types Of Skin Cancer
Some precancerous growths, often attributable to sun exposure, can lead to skin cancer over time. However, if they are recognized and removed early, you could avoid a cancer diagnosis. These growths include:
- Actinic keratosis: About 40-60% of squamous cell cancer cases began as actinic keratosis. Anywhere between 2-10% of these growths will develop into SCC, sometimes in as little as a couple of years. Actinic cheilitis is a type of actinic keratosis that appears on the lower lip, and is at higher risk for developing into skin cancer
- Bowens disease: This early, noninvasive form of SCC is at high risk of becoming skin cancer if not addressed. It presents as an eczema-like scaly patch and is usually red or brown in color. These growths have been linked to sun exposure, radiation, carcinogen exposure, genetics, and trauma
- Leukoplakia: These white patches on the lips, tongue, and gums may be caused by alcohol and tobacco use, and can turn into squamous cell carcinoma. Cancer sites on the lips may be caused by sun damage
- Keratoacanthoma: This dome-shaped growth is usually found on sun-exposed skin and usually grows quickly at first, then slows down. Many shrink and go away on their own, but if they continue to grow, this tumor can turn into squamous cell carcinoma. They are usually removed surgically

Exams And Tests For Skin Cancer
If you think a mole or other skin lesion has turned into skin cancer, your primary care provider will probably refer you to a dermatologist. The dermatologist will examine any moles in question and, in many cases, the entire skin surface. Any lesions that are difficult to identify, or are thought to be skin cancer, may then be checked. Tests for skin cancer may include:
- The doctor may use a handheld device called a dermatoscope to scan the lesion. Another handheld device, MelaFind, scans the lesion then a computer program evaluates images of the lesion to indicate if it’s cancerous.
- A sample of skin will be taken so that the suspicious area of skin can be examined under a microscope.
- A biopsy is done in the dermatologist’s office.
If a biopsy shows that you have malignant melanoma, you may undergo further testing to determine the extent of spread of the disease, if any. This may involve blood tests, a chest X-ray, and other tests as needed. This is only needed if the melanoma is of a certain size.

What Is A Melanocyte
Melanocytes are skin cells found in the upper layer of skin. They produce a pigment known as melanin, which gives skin its color. There are two types of melanin: eumelanin and pheomelanin. When skin is exposed to ultraviolet radiation from the sun or tanning beds, it causes skin damage that triggers the melanocytes to produce more melanin, but only the eumelanin pigment attempts to protect the skin by causing the skin to darken or tan. Melanoma occurs when DNA damage from burning or tanning due to UV radiation triggers changes in the melanocytes, resulting in uncontrolled cellular growth.
Naturally darker-skinned people have more eumelanin and naturally fair-skinned people have more pheomelanin. While eumelanin has the ability to protect the skin from sun damage, pheomelanin does not. Thats why people with darker skin are at lower risk for developing melanoma than fair-skinned people who, due to lack of eumelanin, are more susceptible to sun damage, burning and skin cancer.
Signs Of Merkel Cell Cancer
Merkel cell cancer growths usually appear as firm, painless bumps or sores. They are found on sun-exposed areas of the body, especially the head, neck, and eyelids. The growths look like pearly pimple-like lumps and may be difficult to recognize. They can be pink, red, or purplish-blue. They usually grow quickly, which is why they are three to five times deadlier than melanoma.
A helpful way to spot Merkel cell cancer is by using the AEIOU tool:
- Asymptomatic: Most lesions are not painful or tender to the touch
- Expanding: Merkel cell cancer growths expand and grow quickly
- Immunocompromised: A compromised immune system puts someone at higher risk
- Older: More common in individuals over age 50
- UV-exposed skin: Lesions are more likely to present on sun-exposed skin

Who Is At Risk
Much like with BCC, the more time you spend in the sun, the more at risk you are for developing SCC. About 90% of nonmelanoma skin cancers are caused by sun exposure, and people who have tanned indoors have a 67% higher risk of developing squamous cell carcinoma.
Your risk for SCC is higher if you:
- Have a history of skin cancer
- Have a history of unprotected exposure to the sun or tanning beds
- Have a weakened immune system due to a chronic condition or medication
- Are over age 50
- Have a history of chronic skin infections, precancerous skin growths or human papillomavirus
After Skin Cancer Treatment
Most skin cancer is cured surgically in the dermatologist’s office. Of skin cancers that do recur, most do so within three years. Therefore, follow up with your dermatologist as recommended. Make an appointment immediately if you suspect a problem.
If you have advanced malignant melanoma, your oncologist may want to see you every few months. These visits may include total body skin exams, regional lymph node checks, and periodic chest X-rays and body scans. Over time, the intervals between follow-up appointments will increase. Eventually these checks may be done only once a year.

What Is Squamous Cell Carcinoma Of The Skin
Squamous cells are found throughout the human body. These cells line organs, such as the lungs, throat, and thyroid. We also have squamous cells in our skin.
The job of squamous cells is to protect what lies beneath. In our skin, these cells sit near the surface, protecting the tissue beneath.
Anywhere we have squamous cells, we can develop a type of cancer called squamous cell carcinoma .
In the skin, this cancer is usually not life-threatening. It tends to grow slowly, but it can grow deep. When the cancer grows deep, it can injure nerves, blood vessels, and anything else in its path. As the cancer cells pile up, a large tumor can form.
Most people who develop this skin cancer have fair skin that they seldom protected with sunscreen or sun-protective clothing. Before developing this skin cancer, they tend to notice signs of sun damage on their skin, such as age spots, patches of discolored skin, and deep wrinkles.
Anyone can develop squamous cell carcinoma
While anyone can develop this skin cancer, you have a greater risk if you live with a transplanted organ, use tanning beds, or have fair skin that you seldom protected from the sun.
Another sign of sun-damaged skin is having one or more pre-cancerous growths on your skin called actinic keratoses . Some AKs progress, turning into squamous cell carcinoma of the skin.

What Happens If Basal Cell Carcinoma Is Left Untreated
Basal cell carcinoma is the most common type of skin cancer, and it is considered very low risk for metastasizing and spreading to other parts of the body. It is typically very slow-progressing and is usually diagnosed and treated in very early stages. If left untreated, basal cell carcinomas can be locally destructive to the tissues where it grows, and it can invade deeper structures such as nerves, cartilage, and even bone. In most cases, basal cell carcinoma develops on the face, ears, neck, head, shoulders, hands, and other areas that receive frequent sun exposure. The tumors may look like raised bumps on the skin that are usually smooth and pearly/shiny in appearance. Blood vessels can sometimes be seen within the lesions, and in some cases, a wound may form and bleed easily.
Skin Color And Being Exposed To Sunlight Can Increase The Risk Of Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk.
Risk factors for basal cell carcinoma and squamous cell carcinoma of the skin include the following:
- Being exposed to natural sunlight or artificial sunlight over long periods of time.
- Having a fair complexion, which includes the following:
- Fair skin that freckles and burns easily, does not tan, or tans poorly.
- Blue, green, or other light-colored eyes.
- Red or blond hair.
Although having a fair complexion is a risk factor for skin cancer, people of all skin colors can get skin cancer.
Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.

A Dangerous Skin Cancer
Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma and squamous cell carcinoma , melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.
Learn more about melanoma types, risk factors, causes, warning signs and treatment.
Only 20-30% of melanomas are found in existing moles.
While 70-80% arise on normal-looking skin.
