What Are The Screening Recommendations
Though many organizations promote regular total body skin checks, the Centers for Disease Control and Prevention notes that the U.S. Preventive Services Task Force has concluded that theres not enough evidence to recommend for or against routine screening to detect skin cancers early.
However, skin checks are recommended for people with a history of skin cancer or those who have any suspicious-looking lesions or moles.
Additionally, the CDC says you may want to talk to your doctor if you have certain risk factors for skin cancer, such as:
- Light skin

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.
When You Might Need An Imaging Test
You doctor should not order any imaging tests unless theres a good reason to think the skin cancer has spread.
If there are signs that the cancer has spread to your lymph nodes or beyond, then you may need an imaging test.

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.

Should I Have Routine Skin Cancer Screenings
While many routine cancer screenings, such as colonoscopies and mammograms, are recommended when a person reaches a certain age, there are no widely adopted age standards for dermatological screenings. Most primary physicians will perform a quick skin check at a routine physical, but we recommend that those with a higher risk for skin cancer have a thorough skin screening by a dermatologist at least once a year. This includes anyone with:
- A family history of melanoma in two or more blood relatives
- Multiple atypical moles
- Numerous actinic keratoses
- An organ transplant

Diagnosis Of Melanoma Skin Cancer
Diagnosis is the process of finding out the cause of a health problem. Diagnosing melanoma skin cancer usually begins with a visit to your family doctor. Your doctor will ask you about any signs or symptoms you have and do a skin exam. Based on this information, your doctor may refer you to a specialist, such as a dermatologist or surgeon.
The process of diagnosis may seem long and frustrating. Its normal to worry, but try to remember that other health conditions can cause similar signs and symptoms as melanoma skin cancer. Its important for the healthcare team to rule out other reasons for a health problem before making a diagnosis of melanoma skin cancer.
The following tests are usually used to rule out or diagnose melanoma skin cancer. Many of the same tests used to diagnose cancer are used to find out the stage .
Risks Of Skin Cancer Screening
Screening tests have risks.
The risks of skin cancer screening tests include the following:
Finding skin cancer does not always improve health or help you live longer.
Screening may not improve your health or help you live longer if you have advancedskin cancer.
Some cancers never cause symptoms or become life-threatening, but if found by a screening test, the cancer may be treated. Treatments for cancer may have serious side effects.
False-negative test results can occur.
Screening test results may appear to be normal even though cancer is present. A person who receives a false-negative test result may delay getting medical care even if there are symptoms.
False-positive test results can occur.
Screening test results may appear to be abnormal even though no cancer is present. A false-positive test result can cause anxiety and is usually followed by more tests , which also have risks.
A biopsy may cause scarring.
When a skin biopsy is done, the doctor will try to leave the smallest scar possible, but there is a risk of scarring and infection.
Talk to your doctor about your risk for skin cancer and your need for screening tests.

Learn your ABCDEs, the changes in a mole or skin growth that are warning signs of melanoma:
- Asymmetry: One half doesn’t match the other half.
- Border irregularity: The edges are ragged, notched, or blurred.
- Colour: The pigmentation is not uniform. Shades of tan, brown, and black are present. Dashes of red, white, and blue add to the mottled appearance. Colour may spread from the edge of a mole into the surrounding skin.
- Diameter: The size of the mole is greater than 6 mm , or about the size of a pencil eraser.
- Evolution: There is a change in the size, shape, symptoms , surface , or colour.
A melanoma may also look like a bruise that isn’t healing, or it may show up as a brown or black streak under a fingernail or toenail.

What Happens During A Skin Cancer Full Body Exam
The screening usually takes 10 minutes, or longer if the doctor sees any moles that look unusual. Youll take off all of your clothes and put on a medical exam gown. Your doctor will ask if you have any moles that concern you. Then, they will then look at every inch of your body — from your face, chest, arms, back, and legs to less-visible places like your scalp, between your toes, and the soles of your feet.
What Happens If They Find Something
If your doctor finds a spot that could be cancerous orpre-cancerous, theyll likely want to take a picture for your medical chart andperform a skin biopsy.
During a biopsy, the doctor will remove a small amount of tissueto be examined under a microscope by a pathologist. This is a simple procedurethat can be done right then and there, in the office. Theyll clean the area ofskin where the spot is located, numb it with an injection of anesthesia, anduse a blade or scalpel to take a sample of the skin. You shouldnt feel anypain, aside from the pinch from the injection.
That sample will be sent to the lab for testing, and your doctor willshare the results with you when they are available. This usually happens withina few days but could take up to a week or longer.
If the spot turns out to be cancerous, it may need to becompletely removed or treated with other methods, Dr. Riley says.

What Can You Expect From A Skin Cancer Exam
If youre scheduled for a skin cancer screening, here are a few things to help you prepare for the screening:
- Dont wear makeup. This will allow your doctor to more easily examine the skin on your face.
- Remove any nail polish. This will allow your doctor to fully examine your fingers, nails, and nail beds.
- Keep your hair loose so your scalp can be examined.
- Take note of any concerns, like skin spots, patches, or moles, and point those out to your doctor before the exam.
Before the skin screening exam begins, youll need to take off all your clothes and put on a gown. Depending on your skin cancer risk and medical history, you may be allowed to keep your underwear on.
Your doctor will conduct a head-to-toe examination of all your skin. It may include the skin on your buttocks and genitals. Your doctor will likely use a bright light and magnifying glass to examine your skin more thoroughly.
If your doctor finds anything suspicious, theyll decide if it should be monitored or removed. A mole or tissue sample can be removed immediately or on a return appointment.
The tissue will be sent to a lab to see whether it contains cancer cells. Your doctor should receive the results within a week or two, and will share the results with you.
Research Is Promising But Accuracy Isn’t Quite There
Of all the apps discussed here, SkinVision seems to have the most research behind it.
A 2014 study on an older version of SkinVision reported 81% accuracy in detecting melanoma, which at the time researchers said was “insufcient to detect melanoma accurately.”
However, a new 2019 study published in the Journal of the European Academy of Dermatology and Venereology determined that SkinVision can detect 95% of skin cancer cases. It’s encouraging to see the company continue to work on app accuracy, as early detection of skin cancer is the number-one way to achieve successful treatment.
In another study, researchers from the University of Pittsburgh, analyzed four smartphone apps that claim to detect skin cancer. We don’t know the exact apps, as they’re named only as Application 1, 2, 3 and 4. Three of the apps used algorithms to send immediate feedback about the person’s risk of skin cancer, and the fourth app sent the photos to a dermatologist.
Unsurprisingly, the researchers found the fourth app be the most accurate. The other three apps were found to incorrectly categorize a large number of skin lesions, with one missing nearly 30% of melanomas, classifying them as low-risk lesions.
A 2018 Cochrane review of prior research found that AI-based skin cancer detection has “not yet demonstrated sufficient promise in terms of accuracy, and they are associated with a high likelihood of missing melanomas.”

Why Should I Get Tested
Malignant Melanoma is rare but is the most serious skin cancer. Left untreated, it can spread in the body and can eventually be fatal.
Malignant melanoma is disproportionately high in younger people, but they also have the highest probability of longer-term survival from the disease. According to Cancer Research UK, five-year skin cancer survival rates are highest in the 15-39 age group for patients diagnosed between 2009-2013.
Non-melanoma skin cancer is much more common than malignant melanoma. It is usually detected at a much earlier stage and is less likely to be life-threatening. Accurate statistics about non-melanoma skin cancer are difficult to obtain as cases of this type are often dealt with in local clinics.
How To Detect Skin Cancer
When it comes to skin cancer, we have some good news and some bad news.
First, the bad news: skin cancer is the most commonly diagnosed cancer in the United States. Each year, nearly 5 million people are treated for skin cancer, and in the last three decades, more Americans have had skin cancer than all other cancers combined.
But heres the good news: You can often see the early warning signs of skin cancer…without an x-ray or blood test or special diagnostic procedure. If you know what to look for and take action when you see it, most skin cancers can be detected and treated at early stages, when they are most curable.
Even for melanoma, a more dangerous skin cancer type that is more likely to spread to other body areas, the five-year survival rate is 99% for people whose melanoma is detected and treated before it spreads to the lymph nodes.

Can Changing My Diet Help Prevent Melanoma
The American Cancer Society advocates eating a plant-based diet over an animal-based diet as part of a healthy plan to avoid all cancers. Growing evidence suggests that plants pack a powerful punch in any fight against cancer because they’re nutritious, cholesterol-free and fiber-rich.
Theres no doubt that a healthy diet can protect your immune system. Having a strong immune system is important to help your body fight disease. Some research has shown that a Mediterranean diet is a healthy choice that may help prevent the development of cancer. Talk to your healthcare provider about the role food plays in lowering your cancer risks.
Some skin and immune-system healthy foods to consider include:
- Daily tea drinking: The polyphenols in tea help strengthen your immune system. Green tea contains more polyphenols than black tea.
- High vegetable consumption: Eating carrots, cruciferous and leafy vegetables is linked to the prevention of cutaneous melanoma.
- Weekly fish intake: Study participants who ate fish weekly seemed to avoid developing the disease when compared to those who did not eat fish weekly.
How To Reduce Your Risk
A number of changes to your lifestyle can significantly reduce your risk of skin cancer including:
- Avoid over exposure to the sun
- Avoid the use of sunbeds
- Wear a hat or protective clothing to protect your head, face, neck and shoulders
- Apply a high-factor 4star + rated, waterproof sunscreen every two hours
- Wear sunglasses with UV protection
- Move into the shade from 11.00hrs -15.00hrs when UV is strongest

How Can I Detect Skin Cancer
The first answer is to simply look at your skin. Because you see your skin every day, you are detector number one. By knowing what is normal for your skin, and then thoroughly inspecting it on a regular usually monthly basis, many skin cancers can be self- detected.
When examining your skin, take note of all existing spots, moles and freckles on your skin, so that youll know when changes occur or a new one appears. You can track these easily with this body mole map from the American Academy of Dermatology. Stand in front of mirror and examine your front and back, head to toe. Bend your elbows and look carefully at your forearms, palms and the back of your upper arms. Use a hand mirror to check the back of your neck, scalp, buttocks and other hard-to-see places. Dont forget the bottoms of your feet and between your toes.
Skin Cancer Is A Disease In Which Malignant Cells Form In The Tissues Of The Skin
The skin is the body’s largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D. The skin has several layers, but the two main layers are the epidermis and the dermis . Skin cancer begins in the epidermis, which is made up of three kinds of cells:
- Squamous cells: Thin, flat cells that form the top layer of the epidermis. Cancer that forms in squamous cells is called squamous cell carcinoma of the skin.
- Basal cells: Round cells under the squamous cells. Cancer that forms in basal cells is called basal cell carcinoma.
- Melanocytes: Found in the lower part of the epidermis, these cells make melanin, the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to tan, or darken. Cancer that forms in melanocytes is called melanoma.
