Nonmelanoma Skin Cancer Is The Most Common Cancer In The United States
There are two main types of skin cancer:
- Squamous cell carcinoma .
Basal cell carcinoma and squamous cell carcinoma of the skin, also called nonmelanoma skin cancer, are the most common forms of skin cancer. Most basal cell and squamous cell skin cancers can be cured.
Melanoma is more likely to spread to nearby tissues and other parts of the body and can be harder to cure. Melanoma is easier to cure if the tumor is found before it spreads to the dermis . Melanoma is less likely to cause death when it is found and treated early.
In the United States, about 3 million cases of nonmelanoma skin cancer are diagnosed each year, and rates have likely been increasing in recent years. The number of cases of melanoma has been increasing for at least 40 years. Part of the reason for these increases may be that people have become more aware of skin cancer. They are more likely to have screening exams and do self-exams. As a result, they are more likely to be diagnosed with skin cancer.
From 2014 to 2018, the number of deaths from melanoma decreased slightly in all age groups.
The number of cases of childhood melanoma diagnosed in the United States is low, but increasing over time. The number of childhood deaths from melanoma has stayed about the same.

Biopsies Of Melanoma That May Have Spread
Biopsies of areas other than the skin may be needed in some cases. For example, if melanoma has already been diagnosed on the skin, nearby lymph nodes may be biopsied to see if the cancer has spread to them.
Rarely, biopsies may be needed to figure out what type of cancer someone has. For example, some melanomas can spread so quickly that they reach the lymph nodes, lungs, brain, or other areas while the original skin melanoma is still very small. Sometimes these tumors are found with imaging tests or other exams even before the melanoma on the skin is discovered. In other cases, they may be found long after a skin melanoma has been removed, so its not clear if its the same cancer.
In still other cases, melanoma may be found somewhere in the body without ever finding a spot on the skin. This may be because some skin lesions go away on their own after some of their cells have spread to other parts of the body. Melanoma can also start in internal organs, but this is very rare, and if melanoma has spread widely throughout the body, it may not be possible to tell exactly where it started.
When melanoma has spread to other organs, it can sometimes be confused with a cancer starting in that organ. For example, melanoma that has spread to the lung might be confused with a primary lung cancer .
Biopsies of suspicious areas inside the body often are more involved than those used to sample the skin.
What Should You Do If You Notice A New Or Abnormal Mole Or Freckle
Heres a quick guide to deciding whether a new or changing mole, freckle, or spot on your body may need to be seen by a doctor:
- Asymmetry. Is the spot different shapes on each side? Spots that arent perfectly round or symmetrical may be an early sign of skin cancer.
- Border irregularity. Is the border around the area jagged or irregular? Look at where the color of the spot contrasts with the color of your skin. If this line is not clearly defined, the spot may be at a higher risk of becoming cancerous.
- Color. Is the color consistent throughout the spot? Areas that are multiple shades of tan, brown, or black may be a cause for concern.
- Diameter. Is it larger than 1/4 of an inch? Large spots that are bigger than this are more likely to become cancerous, especially if they keep growing.
- Evolving. Does it change each time you look at it? Areas that change may result from irregular cancerous cell growth that a dermatologist needs to examine.
The above are possible signs of melanoma.
You should also see a dermatologist if you notice anything that:
- does not heal
- is pink, scaly, and does not resolve
- is a new, abnormal growth
These can be signs of non-melanoma skin cancers, such as basal cell or squamous cell.
You can also talk with a doctor about anything your find concerning, even if the mole or freckle does not meet any of the above requirements. If youre ever nervous or uncertain about your health, talking with a doctor can help you get answers.

Potential Benefits Of Skin Cancer Detection Apps
Healthcare professionals have expressed two main arguments related to skin cancer detection apps. The first raises concern that people may rely on apps and consumer devices to assess their risk of skin cancer, which could lead to delayed diagnosis. The second praises these apps for raising awareness among the public and encouraging people to take better care of their skin.
Both arguments are valid.
In the SkinVision study, for example, the researchers say, “We see the main potential for the smartphone applications in the improvement of the patient-doctor communication by making aware of the need of skin cancer screening and by giving a basis of interaction.”
Additionally, apps like MoleScope that send images to dermatologists can serve as the first step in receiving a professional exam. All skin cancer biopsies begin with a visual exam, after all. However, you shouldn’t use any at-home app or device to replace professional medical care for any condition.
Most skin cancer app developers know this and include a disclaimer on their websites that their app is not a replacement for professional healthcare.
What Do The Results Mean
If a mole or other mark on your skin looks like it might be a sign of cancer, your provider will probably order another test, called a skin biopsy, to make a diagnosis. A skin biopsy is a procedure that removes a small sample of skin for testing. The skin sample is looked at under a microscope to check for cancer cells. If you are diagnosed with skin cancer, you can begin treatment. Finding and treating cancer early may help prevent the disease from spreading.

What Increases Your Risk
A risk factor for melanoma is something that increases your chance of getting this cancer. Having one or more of these risk factors can make it more likely that you will get melanoma. But it doesn’t mean that you will definitely get it. And many people who get melanoma don’t have any of these risk factors.
Risk factors for melanoma include:footnote 1
- Too much exposure to the sun’s UV rays. This includes:
- Having had blistering sunburns at any time of life.
- Getting intense sun exposure every now and then.
Brazil Failed To Diagnose 17200 Cases Of Skin Cancer In 2020 Anna Marina

Data collected by the Brazilian Society of Dermatology point to a worrying reality for efforts to prevent and fight skin cancer. In Minas Gerais, during 2020, the most critical moment of the pandemic, 1,708 fewer diagnoses were made compared to 2019. This means that the absolute number of cases was 22% lower than that recorded in the period prior to the advance of the new coronavirus.
Generally speaking, this means that thousands of people with skin cancer must start treatment late. Or worse: the disease has not even been discovered by doctors, which has a direct impact on the chances of recovery and cure.
From January to June of this year, there was a gradual resumption of the volume of assistance, however the numbers are still lower than those recorded in the pre-pandemic stage.
The release of these data coincides with the beginning of the December Orange campaign, organized by the SBD, with the objective of making the population aware of the risks of skin cancer. In addition to encouraging the adoption of day-to-day photoprotection habits, the initiative advises people to look for a dermatologist if suspicious signs or symptoms appear.
The worst rates were observed in April and May of last year, immediately after the decree of public calamity in the country, with a drop of 51.7% and 57%, respectively, in terms of detection.

Tests Are Used To Screen For Different Types Of Cancer When A Person Does Not Have Symptoms
Scientists study screening tests to find those with the fewest harms and most benefits. Cancer screening trials also are meant to show whether early detection helps a person live longer or decreases a person’s chance of dying from the disease. For some types of cancer, the chance of recovery is better if the disease is found and treated at an early stage.

The Importance Of Annual Exams
The easiest and most effective way to detect skin cancer is to self-check your skin and go to a dermatologist regularly for a check-up.
Experts disagree on what groups of people should get annual exams: Some say you only need a screening if you have suspicious moles or risk factors for melanoma others say everyone should get an annual skin check.
A few factors increase your risk of skin cancer, and if you have any of these, you would benefit from a yearly check-up:
- Fair skin, light eyes and blonde or red hair
- Skin that burns or freckles easily
- A family history of any type of skin cancer
- History of tanning bed use
- History of severe sunburns
- Unusual moles or more than 50 moles on your body
For now, even though these apps may be helpful in some ways, your best bet is to seek the professional opinion of a dermatologist or doctor if you notice any suspicious moles or other warning signs of skin cancer.

Skin cancer is actually one of the easiest cancers to find. Thats because skin cancer usually begins where you can see it.
You can get skin cancer anywhere on your skin from your scalp to the bottoms of your feet. Even if the area gets little sun, its possible for skin cancer to develop there.
You can also get skin cancer in places that may surprise you. Skin cancer can begin under a toenail or fingernail, on your genitals, inside your mouth, or on a lip.
Ways To Check For Skin Cancer With Your Smartphone
Your phone can help you recognize suspicious moles and marks, but you should still see a dermatologist about concerns.
Early detection of skin cancer could be the difference between a simple mole removal or several rounds of chemotherapy.
While skin care advice most commonly comes about at the brink of summer, your skin can get damaged by UV rays no matter what time of year, no matter what the weather. Skin cancer accounts for more diagnoses each year than all other cancers, but the good news is that early detection could be the difference between a simple mole removal or malignant cancer that spreads to other parts of the body.
A handful of smartphone apps and devices claim to aid early detection and keep you on track with regular self-exams. You can capture photos of suspicious moles or marks and track them yourself, or send them off to a dermatologist for assessment. Either way, these apps can be helpful, but they do have limitations, so it’s important to follow conventional wisdom to protect yourself. Here’s what you need to know about using your smartphone to detect skin cancer.

Better To Be Safe Than Sorry
Even though most people understand that they need to book a skin cancer check if they find a suspiciously looking mole or freckle on their body, it is not always possible to be aware of its existence if the mole is in a hard to view location. It is also not uncommon for people to have a significant misconception about what a suspicious spot may look like. We frequently have patients come to our practice wanting us to diagnose a skin concern, only for it to be assessed and determined that its nothing to worry about. However, while screening the patient, they may discover moles or freckles that actually are of great concern, surprising the patient who would never have thought those were anything to worry about or perhaps didnt even know they were there. Therefore, a regular full body skin cancer exam by an experienced practitioner will give you the best chance of catching skin cancer in the early stage of development so treatment can be sought.
