Differences In Skin Cancer Appearance
The relationship between race, ethnicity, and skin cancer is complex. One of the main differences in its presentation occurs due to variations in skin color.
Skin tone has a significant influence on how skin cancer looks. People with lighter skin tones may develop growths different in color to the surrounding skin, making them more noticeable. However, in those with darker skin, cancerous growths may be skin-colored and therefore less noticeable.
This is true both across racial groups and within them. For example, a Black person with lighter skin may notice a dark-colored growth more easily than a Black person with highly pigmented skin.
Another factor for people to consider is a potential difference in skin cancers location. In skin of color, melanoma is to appear in less obvious places, such as:
- palms of the hands
- black, pearly, and translucent skin growth
- moles that bleed or grow in size
A person should speak with a doctor as soon as possible about any growths with these characteristics.
White people appear to have a generally higher vulnerability to skin cancer than other groups. This is probably due to the lack of melanin in lighter skin, making it easier for UV light to cause damage.
However, a also highlights that a lack of diversity in trials and studies means that scientists may not accurately understand how common skin cancer is in skin of color.
Here are the different rates for specific types of cancer:
What Are The Risk Factors For Squamous Cell Carcinoma
Squamous cell carcinoma is mainly caused by cumulative ultraviolet exposure from the sun, according to Dr. Leffell.
Daily year-round exposure to the suns UV light and intense exposure in the summer months add to the damage that causes this type of cancer, he says. People at the highest risk for squamous cell carcinoma tend to have light or fair-colored skin blue, green or gray eyes a history of sun exposure and a tendency to sunburn quickly. Squamous cell carcinoma occurs four times more frequently in men than in women.
Although squamous cell carcinoma can be more aggressive than basal cell cancer, the risk of this type of cancer spreading is lowas long as the cancer is treated early, Dr. Leffell says. He notes that the lesions must be treated with respect because they may grow rapidly and invade deeply. While it is more difficult to treat squamous cell carcinoma that has metastasized, up to half of cases can be cured.
In a small percentage of cases, squamous cell carcinoma can grow along the tiny nerves in the skin. In this very serious condition, the squamous cell carcinoma of the face or scalp can travel along the nerves and spread to the brain.
Curettage Electrodesiccation And Cryotherapy
Some dermatologists perform curettage, electrodesiccation, and cryotherapy to treat skin cancer. These are considered to be destructive techniques that are best suited for small, superficial carcinomas with definite borders. During the procedure, layers of skin cells are scraped away using a curette. Any remaining cancer cells are destroyed with the use of an electric needle.
In some cases, liquid nitrogen or cryotherapy is used to freeze the margins of the treatment area. Extremely low temperatures kill the malignant skin cells and create a wound, which will heal in a few weeks. The treatment may leave scars that are flat and round, similar to the size of the skin cancer lesion.

How Is Skin Cancer Diagnosed
First, your dermatologist may ask you if you have noticed any changes in any existing moles, freckles or other skin spots or if youve noticed any new skin growths. Next, your dermatologist will examine all of your skin, including your scalp, ears, palms of your hands, soles of your feet, between your toes, around your genitals and between your buttocks.
If a skin lesion is suspicious, a biopsy may be performed. In a biopsy, a sample of tissue is removed and sent to a laboratory to be examined under a microscope by a pathologist. Your dermatologist will tell you if your skin lesion is skin cancer, what type you have and discuss treatment options.
How Quickly Does Skin Cancer Appear On The Body
Have you noticed the appearance of a sudden, unusual growth on your skin? Certain types of skin cancer, like melanoma, can show up very quickly and without warning. So, how can you know if its truly a cause for concern? The only way to determine if a skin growth is cancerous is by getting a skin cancer screening from a qualified provider. The expert dermatology team at Advanced Dermatology offers skin cancer screenings to detect many types of skin cancer and can offer a variety of appropriate treatment solutions at our practice locations in Katy, League City, Pearland, and Sugar Land, TX. So, reach out to us for a screening as soon as you notice an irregular spot.
How long does it take skin cancer to appear?
There’s no set timeline for skin cancer growth and appearance. While some skin cancer lesions appear suddenly, others grow slowly over time. For example, the crusty, pre-cancerous spots associated with actinic keratoses can take years to develop. Other forms of skin cancer, like melanoma, can appear very suddenly, while at other times, the lesions can vanish and reappear.

Signs of skin cancer
The specific symptoms can vary based on each individual type of skin cancer. During a skin cancer screening performed in one of our Houston, TX area offices, our dermatologists look for the following types of cancer:

Melanoma Can Go Away On Its Own
Melanoma on the skin can spontaneously regress, or begin to, without any treatment. Thats because the bodys immune system is able launch an assault on the disease thats strong enough to spur its retreat. Unfortunately, sometimes this happens only after the disease has spread to other parts of the body, such as the liver, lungs, bones, or brain.
The observation that the immune system can cause melanoma to regress was one of the key insights that led to the development of immunotherapy as a successful treatment for melanoma, explains Dr. Marghoob. The thinking went, if the immune system can get rid of melanoma on its own, there must also be a way to enhance the immune systems natural ability to fight melanoma. This eventually led researchers to develop drugs designed to enhance the immune systems ability to successfully fight melanoma that has spread.
How Common Is Skin Cancer
Skin cancer is the most common cancer diagnosed in the U.S.
Other skin cancer facts:
- Around 20% of Americans develop skin cancer sometime in their life.
- Approximately 9,500 Americans are diagnosed with skin cancer every day.
- Having five or more sunburns in your life doubles your chance of developing melanoma. The good news is that the five-year survival rate is 99% if caught and treated early.
- Non-Hispanic white persons have almost a 30 times higher rate of skin cancer than non-Hispanic Black or Asian/Pacific Islander persons.
- Skin cancer in people with skin of color is often diagnosed in later stages when its more difficult to treat. Some 25% of melanoma cases in African Americans are diagnosed when cancer has spread to nearby lymph nodes.

Alternative Treatment Options: Radiation Therapy
For Squamous and Basal cell cancer, Mohs surgery is often not the only viable treatment option. The invasive nature of Mohs surgery coupled with the possibility of scarring and the need for antibiotics following the procedure makes some patients uneasy.
If you are searching for a non-invasive alternative, youll want to learn more about Image Guided Superficial Radiotherapy . IG-SRT uses Ultrasound Imaging and Superficial Radiotherapy to treat Basal and Squamous cell cancers with a precise, measured dose of radiation delivered directly under the patients skin surface. It is completely non-invasive and has less of an effect on the patients daily life post-treatment, with no scarring, no need for antibiotics, and no requirement to stop taking certain medications prior to the procedure.
What Are The Signs Of Skin Cancer
The most common warning sign of skin cancer is a change on your skin, typically a new growth, or a change in an existing growth or mole. The signs and symptoms of common and less common types of skin cancers are described below.
Basal cell carcinoma
Basal cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. Basal cell cancer is the most common type of skin cancer in the world. In most people, its slow growing, usually doesnt spread to other parts of the body and is not life-threatening.
Signs and symptoms of basal cell carcinoma include:
- A small, smooth, pearly or waxy bump on the face, ears, and neck.
- A flat, pink/red- or brown-colored lesion on the trunk or arms and legs.
- Areas on the skin that look like scars.
- Sores that look crusty, have a depression in the middle or bleed often.
Squamous cell carcinoma
Squamous cell cancer is most commonly seen on sun-exposed areas of skin including your hands, face, arms, legs, ears, mouths, and even bald spots on the top of your head. This skin cancer can also form in areas such as mucus membranes and genitals.
Signs and symptoms of squamous cell carcinoma include:
- A firm pink or red nodule.
- A rough, scaly lesion that might itch, bleed and become crusty.
Signs and symptoms of melanoma include:
- A brown-pigmented patch or bump.
- A mole that changes in color, size or that bleeds.

What Is Skin Cancer
Cancer can start any place in the body. Skin cancer starts when cells in the skin grow out of control.
Skin cancer cells can sometimes spread to other parts of the body, but this is not common. When cancer cells do this, its called metastasis. To doctors, the cancer cells in the new place look just like the ones from the skin.
Cancer is always named based on the place where it starts. So if skin cancer spreads to another part of the body, its still called skin cancer.
Ask your doctor to use this picture to show you where your cancer is
What Are The Symptoms Of Skin Cancer
Skin cancers first appear as a spot, lump or scaly area on the skin, or a mole that changes colour, size or shape over several weeks or months. These changes can appear anywhere on the body, particularly areas frequently exposed to the sun. Skin cancers may bleed and become inflamed, and can be tender to the touch.
There are certain characteristics to look for in spots and moles. Remember the ‘ABCDE’ of skin cancer when checking your skin:
- Asymmetry does each side of the spot or mole look different to the other?
- Border is it irregular, jagged or spreading?
- Colours are there several, or is the colour uneven or blotchy?
- Diameter look for spots that are getting bigger
- Evolution is the spot or mole changing or growing over time?
Changes may include an area that is scaly, shiny, pale or bright pink in colour, or a spot or lump that grows quickly and is thick, red, scaly or crusted.
See your doctor if you notice any new spots or an existing spot that changes size, shape or colour over several weeks or months. Your doctor can help you distinguish between a harmless spot such as a mole, and a sunspot or irregular mole that could develop later into skin cancer.

E: Evolving And/or Elevated
“E” stands for two different features of melanoma:
- Elevation: Moles are often elevated above the skin, often unevenly so with some parts raised and others flat.
- Evolving: A mole that is evolving is also concerning and, in retrospect, many people with melanomas note that a mole had been changing in terms of size, shape, color, or general appearance before they were diagnosed.
When a melanoma develops in an existing mole, the texture may change and become hard, lumpy, or scaly. Although the skin may feel different and itch, ooze, or bleed, a melanoma does not usually cause pain.

How Is Squamous Cell Carcinoma Treated
Although squamous cell carcinomas usually grow slowly, it is important to see a dermatologist quickly. “The sooner you see your doctor and the cancer is diagnosed and treated, the less complicated the surgery to remove it will be, and the faster you will make a complete recovery, Dr. Leffell explains. The treatment for squamous cell cancer varies according to the size and location of the lesion. The surgical options are the same as those for basal cell cancer:
- Surgical excision: Removing a squamous cell lesion is a simple procedure that typically takes place in the dermatologist’s office. After numbing the cancer and the area around it with a local anesthetic, the doctor uses a scalpel to remove the tumor and some of the surrounding skin to make sure all cancer is eliminated. Estimating how much to take requires skill and expertise, Dr. Leffell notes. The risk of taking too little tissue is that some cancer remains taking too much leaves a larger scar than is necessary. Shaped like a football, the wound is stitched together, using plastic surgery techniques. If dissolvable stitches are used, they will disappear on their own as the area heals. Though the procedure leaves some redness and a small scar, it tends to become less noticeable over time. “The cure rate for this type of excision is typically about 90 to 93 percent,” says Dr. Leffell. But, of course, this is dependent on the skill and experience of the doctor.”
What Is Nonmelanoma Skin Cancer
Skin cancer is a disease that begins in the cells of the skin. The area of skin with the cancer is often called a lesion. There are several types of skin cancer . Melanoma is the most serious. But there are others that are known as nonmelanoma skin cancer. These include:
Basal cell carcinoma
Basal cell carcinoma and squamous cell carcinoma are by far the most common.

What Is My Skin Type
Skin types that are more sensitive to ultraviolet radiation burn more quickly and are at a greater risk of skin cancer.
All skin types can be damaged by too much UV radiation. Skin types that are more sensitive to UV radiation burn more quickly and are at a greater risk of skin cancer.
People with naturally very dark skin still need to take care in the sun even though they may rarely, if ever, get sunburnt. The larger amount of melanin in very dark skin provides natural protection from UV radiation. This means the risk of skin cancer is lower.
Eye damage can occur regardless of skin type. High levels of UV radiation have also been linked to harmful effects on the immune system.
Vitamin D deficiency may be a greater health concern for people with naturally very dark skin, as it is more difficult for people with this skin type to make vitamin D.
How Is Melanoma Diagnosed
If you have a mole or other spot that looks suspicious, your doctor may remove it and look at it under the microscope to see if it contains cancer cells. This is called a biopsy.
After your doctor receives the skin biopsy results showing evidence of melanoma cells, the next step is to determine if the melanoma has spread. This is called staging. Once diagnosed, melanoma will be categorized based on several factors, such as how deeply it has spread and its appearance under the microscope. Tumor thickness is the most important characteristic in predicting outcomes.
Melanomas are grouped into the following stages:
- Stage 0 : The melanoma is only in the top layer of skin .
- Stage I: Low-risk primary melanoma with no evidence of spread. This stage is generally curable with surgery.
- Stage II: Features are present that indicate higher risk of recurrence, but there is no evidence of spread.
- Stage III: The melanoma has spread to nearby lymph nodes or nearby skin.
- Stage IV: The melanoma has spread to more distant lymph nodes or skin or has spread to internal organs.

Risk Of Further Melanomas
Most people treated for early melanoma do not have further trouble with the disease. However, when there is a chance that the melanoma may have spread to other parts of your body, you will need regular check-ups.
Your doctor will decide how often you will need check-ups everyone is different. They will become less frequent if you have no further problems.
After treatment for melanoma it is important to limit exposure to the sun’s UV radiation. A combination of sun protection measures should be used during sun protection times .
As biological family members usually share similar traits, your family members may also have an increased risk of developing melanoma and other skin cancers. They can reduce their risk by spending less time in the sun and using a combination of sun protection measures during sun protection times.
It is important to monitor your skin regularly and if you notice any changes in your skin, or enlarged lymph glands near to where you had the cancer, see your specialist as soon as possible.
