Chances are, you may know someone who’s been diagnosed with skin cancer. It affects millions of Americans every year, making it the most common kind of cancer. And if it’s caught early, it’s also one of the most treatable cancers.
Skin cancer occurs when unrepaired cell damage allows mutations to grow and divide uncontrollably. The main types of skin cancer are melanoma, basal cell carcinoma and squamous cell carcinoma. Skin cancer can be benign or malignant depending on many factors, controllable or inherited, within the individual.
Like other cancers, skin cancer can spread to other parts of the body over time. It can become life-threatening if not treated quickly and appropriately.
There are three types of skin cancer that are most common among the population:
Basal cell carcinoma is a common type of skin cancer. In fact, every year more people get diagnosed with basal cell carcinoma than any other type of cancer. Every day you shed tens of thousands of dead skin cells. Once they flake off, they’re replaced by new healthy cells. This process couldn’t take place without basal cells. However, if cancer invades your basal cells, the cancerous cells multiply instead of dying and flaking off. They can then grow into a solid tumor on your skin.
When caught early, basal cell carcinoma is highly treatable and rarely fatal. But if left untreated, it can cause serious complications. It may grow deep into the skin, killing nearby tissue and bone. And in rare cases, it can spread to other parts of the body.
Squamous cell skin cancer is a common type of skin cancer that can grow quite large, making it hard to remove without scarring. And in rare cases, it can spread to other parts of the body.
Squamous cells are found throughout the body and make up the outer part of your skin. They also line the insides of many organs, including your lungs, bladder and kidneys. If these cancerous cells multiply instead of dying off, they may grow into a solid tumor on your skin.
Malignant melanoma is less common than other skin cancers but is more dangerous because it’s more likely to spread to other organs. Your skin gets its unique color from “melanocytes” (cells that produce a pigment called melanin). Melanocytes also make extra pigment in response to sunlight. That’s why your skin may darken after spending time in the sun.
Because melanoma is a serious condition, doctors recommend you make a plan to have routine skin exams. Your primary care doctor or a dermatologist can check your skin during routine medical visits. They can check hard-to-reach areas that you might not be able to see, like your scalp and back.
It’s possible for anyone to develop skin cancer. But certain risk factors may increase the likelihood of getting it within certain individuals. These risk factors include:
Even if you don’t have any obvious risk factors, you can still get cancer by being exposed to UV (ultraviolet) rays. People of any ethnic background can potentially develop skin cancer from UV exposure. That’s why it’s important to limit your time in the sun and use protective sunscreen while outdoors for extended periods of time.
There are six different skin types that range from very light to very dark. Knowing your specific skin type will help you determine your overall level of risk for contracting skin cancer. Your Mercy doctor can help you if you’re unsure.
Atypical moles, also known as dysplastic nevi, can increase your risk of developing melanoma. Moles can appear anywhere on the body and their appearance can vary. If you notice any new growths on your body, it’s best to get in touch with your primary care provider or a dermatologist to get a second opinion.
A high amount of chemical exposure to certain chemicals can also increase a person’s likelihood of developing skin cancer. Harmful chemicals such as arsenic, coal, tar, paraffin and oil can cause non-melanoma skin cancers to develop in certain individuals. If possible, limiting your exposure to these substances can decrease your risk of developing skin cancer.
If you have a grandparent, parent, sibling or child who was diagnosed with any type of skin cancer, it increases your risk of developing skin cancer. As a general rule, the closer the relative, the higher your personal risk becomes
When it comes to knowing your family’s medical history of cancers, the more information you know the better. If you do discover skin cancer runs in your family, it’s recommended that you set up a full skin examination as soon as possible
Inherited conditions may make you more susceptible to skin cancer. One of the most common disorders is known as xeroderma pigmentosum (XP), a condition where a person suffers from acute sensitivity to ultraviolet rays of sunlight.
In certain instances, some people with XP may also develop neurological disorders as a result of this condition. It’s important to talk to your Mercy doctor if you have any rare skin disorders that run in your family.
Signs and symptoms can vary depending on the type of skin cancer. The signs and symptoms of the 3 types of predominant skin cancers include:
Basal cell carcinoma usually occurs on the skin around the face or neck as a result of excessive sun exposure. But it can occur anywhere on the body. Not all basal cell carcinomas look the same. Signs and symptoms of BCC include:
Squamous cell carcinoma usually occurs on skin with lots of sun exposure, usually around the face, lips, ears and neck. But it can occur anywhere on the body. This includes hidden places like the inside of your mouth or on your genitals. Not all squamous cell skin cancers look the same. Signs of SCC may include:
Melanoma usually occurs on parts of the skin with significant sun exposure. But it can occur anywhere on the body, even in hidden areas. These include on the bottom of your foot, under a fingernail, between your toes or inside of your mouth. Not all malignant melanoma cell skin cancers look the same. Signs of melanoma may include:
If you have a family history of skin cancer, it’s recommended that you schedule a preventive screening with your primary care provider or Mercy dermatologist. Your Mercy doctor might recommend a screening even if you’re not showing any outward signs or symptoms of skin cancer. If your preventive screening returns abnormal results, additional tests may be needed to determine if you have skin cancer.
The main benefit of getting screened for skin cancer before you’re showing any outward symptoms is that if cancer is found, there’s a much better chance of treating it successfully. Early detection will give your Mercy doctor plenty of treatment options when it comes to removing a cancerous mass. If untreated for too long, your cancer will spread to other parts of your body, making it more difficult to treat in the long run.
Catching melanoma at an early stage is crucial to successfully removing cancer. If you’re unsure of whether a mole or part of your skin may be cancerous, remember this mnemonic device:
See a Mercy expert immediately if you notice any new or suspicious-looking moles or bumps. Your primary care doctor or a Mercy dermatologist can check your skin during routine medical visits. They can also check areas that are hard for you to see, like your scalp and back.
