Medical History And Physical Exam
Usually the first step your doctor takes is to ask about your symptoms, such as when the mark on the skin first appeared, if it has changed in size or appearance, and if it has been painful, itchy, or bleeding. You may also be asked about your possible risk factors for melanoma skin cancer, such as your history of tanning and sunburns, and if you or anyone in your family has had melanoma or other skin cancers.
During the physical exam, your doctor will note the size, shape, color, and texture of the area in question, and whether it is bleeding, oozing, or crusting. The rest of your body may be checked for moles and other spots that could be related to skin cancer .
The doctor may also feel the lymph nodes under the skin in the neck, underarm, or groin near the abnormal area. When melanoma spreads, it often goes to nearby lymph nodes first, making them larger.
If you are being seen by your primary doctor and melanoma is suspected, you may be referred to a dermatologist, a doctor who specializes in skin diseases, who will look at the area more closely.
Along with a standard physical exam, many dermatologists use a technique called dermoscopy to see spots on the skin more clearly. The doctor uses a dermatoscope, which is a special magnifying lens and light source held near the skin. Sometimes a thin layer of alcohol or oil is used with this instrument. The doctor may take a digital photo of the spot.
Something Just Looks A Little Odd
Your skin is always changing in fact, it regenerates itself all the time. So, if you notice a spot that doesnt go away over the course of a month, it means that this spot sits in the lower layers of your skin. These skin abnormalities should be checked out by a doctor.
It is a good idea to keep track of the size and shape of your moles so that you can show your doctor a timeline to help with diagnosis. SkinVision is ideal for this, as it enables you to detect signs of skin cancer in time and allows you to archive photos of your moles to track any possible changes.
What Are The Symptoms Of Skin Cancer
Talk to your doctor if you notice changes in your skin such as a new growth, a sore that doesnt heal, a change in an old growth, or any of the A-B-C-D-Es of melanoma.
A change in your skin is the most common sign of skin cancer. This could be a new growth, a sore that doesnt heal, or a change in a mole.external icon;Not all skin cancers look the same.
For melanoma specifically, a simple way to remember the warning signs is to remember the A-B-C-D-Es of melanoma
- A stands for asymmetrical. Does the mole or spot have an irregular shape with two parts that look very different?
- B stands for border. Is the border irregular or jagged?
- C is for color. Is the color uneven?
- D is for diameter. Is the mole or spot larger than the size of a pea?
- E is for evolving. Has the mole or spot changed during the past few weeks or months?

How To Identify Skin Cancer Vs Age Spots
Finding a strange spot on your body can be pretty scary. You dont know how long it will be there, if its dangerous, or what it even is. The best thing you can do when you find weird-looking spot on your body is to visit your dermatologist.
While youre waiting to see a doctor, you may want to better understand two common types of skin spots: skin cancer and age spots, also known as liver spots. Its easy to get the two confused, so lets take a closer look at them.
Melanoma Can Be Tricky
Identifying a potential skin cancer is not easy, and not all melanomas follow the rules. Melanomas come in many forms and may display none of the typical warning signs.
Its also important to note that about 20 to 30 percent of melanomas develop in existing moles, while 70 to 80 percent arise on seemingly normal skin.
Amelanotic melanomas are missing the dark pigment melanin that gives most moles their color. Amelanotic melanomas may be pinkish, reddish, white, the color of your skin or even clear and colorless, making them difficult to recognize.
Acral lentiginous melanoma, the most common form of melanoma found in people of color, often appears in hard-to-spot places, including under the fingernails or toenails, on the palms of the hands or soles of the feet.
The takeaway: Be watchful for any new mole or freckle that arises on your skin, a sore or spot that does not heal, any existing mole that starts;changing; or any spot, mole or lesion that looks unusual.

What Are The Signs And Symptoms Of Skin Cancer
The most common warning sign of skin cancer is a change on the skin, typically a new mole, a new skin lesion or a change in an existing mole.
- Basal cell carcinoma may appear as a small, smooth, pearly, or waxy bump on the face, or neck, or as a flat, pink/red- or brown-colored lesion on the trunk, arms or legs.
- Squamous cell carcinoma can appear as a firm, red nodule, or as a rough, scaly, flat lesion that may itch, bleed and become crusty. Both basal cell and squamous cell cancers mainly occur on areas of the skin frequently exposed to the sun, but can occur anywhere.
- Melanoma usually appears as a pigmented patch or bump. It may resemble a normal mole, but usually has a more irregular appearance.
When looking for melanoma, think of the ABCDE rule that tells you the signs to watch for:
- Asymmetry: The shape of one half doesn’t match the other.
- Border: Edges are ragged or blurred.
- Color: Uneven shades of brown, black, tan, red, white or blue.
- Diameter: A significant change in size .
- Evolution: Changes in the way a mole or lesion looks or feels .
Squamous Cell Skin Cancers
Squamous cell skin cancers can vary in how they look. They usually occur on areas of skin exposed to the sun;like the scalp or ear.

Don’t Miss: How Do You Know If Squamous Cell Carcinoma Has Spread
How Do You Not Know You Have Skin Cancer
During a routine visit to my aesthetician for a facial she mentioned the spot could be a group of clogged pores. She attempted an extraction, but nothing would come out. She advised I see a dermatologist instead of aggravating the area. I was seeing a plastic surgeon for Botox and thought Id ask his opinion the following month, but picked at the spot anyways. When I squeezed the bumps, they expressed oil and then bled. I left the spot alone, but the area formed a scab.
Before the spot turned into a scab it looked EXACTLY like the Google search image for Basal Cell Carcinoma.
A month later I showed my plastic surgeon the area at my Botox appointment. He predicted the spot to be an aggravated cyst, but said, Its too angry to touch. He would be able to remove it once I gave the area three months to heal. This is what it looked like:
Within a few weeks I was in bed with Covid-19 and forgot about the scabbed over spot. The only time I remembered it was there was when it would bleed if I slept on the right side of my face.
Once I was healed from Covid and realized the spot on my face wasnt healing I finally called a doctor. If youre wondering what took me so long to seek medical advice I have something called health anxiety. Its not excuse, but its why I was so negligent of the spot.
How Is Skin Cancer Of The Head And Neck Diagnosed
Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.
Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

The sooner a diagnosis is made, the sooner you can start treatment and the better it is likely to work.
What You Need To Know About Sunburn
- Some people are more prone to sunburn: Skin type determines your susceptibility; people with fair skin run the greatest risk. But anyone can get burned.
- Even without a burn, sun exposure raises skin cancer risk. Even if you are tan or your skin type is dark and your skin does not redden, the sun can cause cellular damage that can lead to cancer.
- The UV index is a factor: The sun varies in intensity by season, time of day and geographic location. A high UV index means that unprotected skin will burn faster or more severely. Be careful, especially when the sun is strongest. But even when the index is low, the risk remains. Protect yourself every day of the year.
- You can burn on an overcast day:;Be careful even when the sun isnt shining. Up to 80 percent of UV rays can penetrate clouds.
- Light pink is still bad: No matter how mild, every burn is a sign of injury to your skin that can result in premature aging and skin cancer.

Tips For Screening Moles For Cancer
Examine your skin on a regular basis. A common location for melanoma in men is on the back, and in women, the lower leg. But check your entire body for moles or suspicious spots once a month. Start at your head and work your way down. Check the “hidden” areas: between fingers and toes, the groin, soles of the feet, the backs of the knees. Check your scalp and neck for moles. Use a handheld mirror or ask a family member to help you look at these areas. Be especially suspicious of a new mole. Take a photo of moles and date it to help you monitor them for change. Pay special attention to moles if you’re a teen, pregnant, or going through menopause, times when your hormones may be surging.
How Are Moles Evaluated
If you find a mole or spot that has any ABCDE’s of melanoma — or one that’s tender, itching, oozing, scaly, doesn’t heal or has redness or swelling beyond the mole — see a doctor. Your doctor may want to remove a tissue sample from the mole and biopsy it. If found to be cancerous, the entire mole and a rim of normal skin around it will be removed and the wound stitched closed. Additional treatment may be needed.

Merkel Cell Carcinoma: A Rare Skin Cancer On The Rise
Merkel cell carcinoma is a rare type of skin cancer that affects about 2,000 people in the United States each year.
Though its an uncommon skin cancer, cases of Merkel cell carcinoma have increased rapidly in the last couple of decades.
This type of cancer starts when cells in the skin, called Merkel cells, start to grow out of control.
Merkel cell carcinomas typically grow quickly and can be difficult to treat if they spread.
They can start anywhere on the body, but Merkel cell carcinomas commonly affect areas exposed to the sun, such as the face, neck, and arms.
They may look like pink, red, or purple lumps that are firm when you touch them. Sometimes, they can open up as ulcers or sores.
Risk factors include:
What To Do If You Notice Skin Changes
If you notice anything unusual on your skin, make an appointment to show it to your GP. It might help to take a photograph of anything unusual, so you can check for any changes. Remember there are many other skin conditions that are not cancer, especially in older people.
It can be more difficult to notice changes if you have darker skin. This is because symptoms of skin cancer may be less obvious than in people with paler skin. If you notice any changes, such as a sore that does not heal, always see your GP.

The Warning Signs Of Skin Cancer
Skin cancers — including melanoma, basal cell carcinoma, and squamous cell carcinoma — often start as changes to your skin. They can be new growths or precancerous lesions — changes that are not cancer but could become cancer over time. An estimated 40% to 50% of fair-skinned people who live to be 65 will develop at least one skin cancer. Learn to spot the early warning signs. Skin cancer can be cured if it’s found and treated early.
Who Gets Skin Cancer And Why
Sun exposure is the biggest cause of skin cancer. But it doesn’t explain skin cancers that develop on skin not ordinarily exposed to sunlight. Exposure to environmental hazards, radiation treatment, and even heredity may play a role. Although anyone can get skin cancer, the risk is greatest for people who have:
- Fair skin or light-colored eyes
- An abundance of large and irregularly-shaped moles
- A family history of skin cancer
- A history of excessive sun exposure or blistering sunburns
- Lived at high altitudes or with year-round sunshine
- Received radiation treatments

How Can I Prevent Skin Cancer
For all types of skin cancer, the first lines of defense are awareness and prevention. Prevention steps center on avoiding ultraviolet radiation exposure from both sunlight and tanning beds. This means staying out of the sun, especially when the suns rays are strongest, between 11 a.m. and 3 p.m.; using a broad-spectrum water-resistant sunscreen with SPF of at least 30 and covering exposed skin with protective clothing when outdoors, even on a cloudy day.
