Skin cancer is the most common type of cancer in the United States. Research suggests that at least 1 in 5 Americans will develop skin cancer by 70 years old.
The condition is also diagnosed in more than 9,500 people every day in the United States. Additionally, more than two people die of skin cancer each hour.
Anyone can get skin cancer, even if they have a higher risk of developing it. People with darker skin tones are more likely to be diagnosed with skin cancer at a later stage.
However, skin cancer is highly preventable. It can also be cured in 99 percent of cases, as long as it’s treated early.
In honor of Skin Cancer Awareness Month in May, this article will focus on the importance of protecting your skin and why it is important to be proactive if you notice any unusual skin changes.
Skin cancer involves the irregular growth of malignant (cancerous) skin cells.
Skin cancer is classified as:
- Nonmelanoma skin cancer. This includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). They’re the most common forms of skin cancer.
- Melanoma skin cancer. Melanoma skin cancer is less common than BCC and SCC. However, it’s more serious since it can quickly spread throughout your body if you do not get early treatment.
There are different types of skin cancer.
- Superficial spreading melanoma. This is the most common type of melanoma, accounting for about 70 percent of all cases. It grows horizontally on the top layer of skin before moving into deeper layers, tends to have an irregular shape and uneven borders, and can be raised or flat. In males, it most often appears on the chest, abdomen, back, head, and neck, while in females, it appears more often on the legs.
- Nodular melanoma. About 15 percent of all melanomas are nodular melanoma. This type of melanoma may look like a raised bump or growth. Unlike other types of skin cancer, nodular melanomas typically develop as a new growth rather than from a preexisting mole. It’s an aggressive type of skin cancer and grows faster than other types of melanomas.
- Acral lentiginous melanoma (ALM). Although it can develop in all skin tones, acral lentiginous melanoma is the most common type of melanoma in people with darker skin tones and those of Asian descent. This type of melanoma often looks like a dark spot that has a clear border between the darkened area and the surrounding skin that’s a regular color. It often appears on or around the hands, feet, or nail beds.
- Subungual melanoma. Subungual melanoma is a type of melanoma that begins in the nail matrix and may start off looking like a vertical bruise under the nail. Although it’s a relatively rare melanoma, it can lead to serious complications. That’s why it’s important to get it diagnosed early.
In people with light or fair skin, melanoma can often be found on the trunk or lower legs. For People of Color, it
In most cases, skin cancer is caused by ultraviolet (UV) light exposure. UV light damages DNA, resulting in cell mutations. UV light also decreases the immune system’s ability to get rid of cancerous cells.
Skin cancer is preventable. Many of the causes can be avoided through certain lifestyle habits.
The following strategies can help reduce skin cancer risk.
Tips for protecting your skin
- Wear sun protection. Apply sunscreen and lip balm with a sun protection factor (SPF) of 30 or higher every day. Wear these products all year round, even when it’s cloudy or rainy.
- Wear sunglasses. Choose sunglasses that block UVA and UVB rays when you’re outside during the day. Pick a wraparound pair, if possible.
- Wear a hat. Protect your face, neck, and ears by wearing a hat with a wide brim and dark fabric. The fabric should be tightly woven.
- Stay in the shade. Whenever possible, stay in shady areas to prevent excessive or intense sun exposure.
- Avoid direct sun exposure. UV rays are the strongest between 10 a.m. to 4 p.m. If possible, stay inside during these times.
- Avoid tanning. Tanning in the sun or in tanning beds can increase your risk of skin cancer.
Paying attention to your skin can help you spot early signs of skin cancer. This involves checking your skin frequently.
- New growths.
- sores that do not heal.
- Changes in moles.
You can do this by doing regular skin self-exams.
- Face a mirror.
- Check your upper body, including your face, ears, neck, chest, and stomach. This includes the skin beneath your breasts.
- Next, look at your arms, hands, and fingernails. Dark lines under your fingernails are a sign.
- Take a look at your lower body, including the top of your legs and feet.
- The skin between your toes and toenails is important.
- Use a hand mirror to look at the back of your legs.
- The bottom of your feet is where you should check.
- Use the mirror to look at your body parts.
- Cut your hair as needed.
The ABCDE rule
When examining your skin, follow the ABCDE rule. This is a guideline for what to look for:
- Asymmetrical. Cancerous spots are often irregular in shape.
- Border. A spot may be cancerous if its border is irregular, jagged, pink, red, or darkened.
- Color. Cancerous spots may be uneven in color. But in some cases, such as nodular melanoma, they can be one color.
- Diameter. A mole or spot that’s bigger than a pea may indicate skin cancer.
- Evolving. If a spot or mole is cancerous, it will likely change in size, shape, or color over a few months or years.
If you notice any changes to your skin, it is important to get a diagnosis from a doctor.
If you have a family history of skin cancer, you may be more likely to get it.
- Have a lighter skin tone.
- Have green or blue eyes.
- Have blond, red, or light brown hair.
- Have freckles.
- Have many moles.
- have irregular or big moles
- Are they younger?
- They are exposed to the sun a lot.
- You can live in a tropical or subtropical region.
- Live at high altitudes.
- Have a compromised immune system.
- Have a family history of skin cancer.
- Have a history of skin cancer.
- They have received an organ transplant.
- Take medications that make your skin more sensitive to the sun.
These factors can increase your risk of skin cancer, regardless of your skin color.
Skin cancer can happen to people with darker skin tones
People with darker skin tones can get skin cancer. The myth is likely due to the higher skin cancer rates in people with lighter skin tones.
Melanin, a skin pigment, can filter UV radiation. People with darker skin tones tend to have more melanin and are less likely to develop skin cancer.
For example, among white people, melanoma is diagnosed in more than 33 per 100,000 people. The rate is 4.5 per 100,000 in Hispanic people and 1 per 100,000 in Black people.
People with darker skin tones can get skin cancer. Skin cancer is more serious in these cases because of late detection. People of Color are more likely to die from skin cancer because of the late diagnosis.
For example, while the prevelance of melanoma has risen within the white population by almost 20 percent in the past 20 years, a
Skin cancer is preventable. It can affect people of all skin tones. People with darker skin tones tend to be diagnosed with skin cancer later in life.
If you want to reduce your risk of skin cancer, apply sunscreen all year round. Wear protective clothing and accessories.
It is important to get yearly skin checks when you visit a doctor. These habits can help detect skin cancer early, when it is the most difficult to treat.
