Staging For Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin Depends On Where The Cancer Formed

How To Identify Skin Cancer

Staging for basal cell carcinoma and squamous cell carcinoma of the eyelid is different from staging for basal cell carcinoma and squamous cell carcinoma found on other areas of the head or neck. There is no staging system for basal cell carcinoma or squamous cell carcinoma that is not found on the head or neck.

Surgery to remove the primary tumor and abnormal lymph nodes is done so that tissue samples can be studied under a microscope. This is called pathologic staging and the findings are used for staging as described below. If staging is done before surgery to remove the tumor, it is called clinical staging. The clinical stage may be different from the pathologic stage.

Can Blood Tests Or Scans Detect Skin Cancer

Currently, blood tests and imaging scans like MRI or PET are not used as screening tests for skin cancer. However, some national studies are underway to determine if concentrations of skin cancer DNA can be detected by blood tests. Occasionally, imaging detects signs of advanced disease. Sometimes, skin cancer that has spread to internal organs is detected incidentally when a patient is undergoing an imaging study such as MRI or PET scan for unrelated conditions.

You Can Find Skin Cancer On Your Body

The best way to find skin cancer is to examine yourself. When checking, you want to look at the spots on your skin. And you want to check everywhere from your scalp to the spaces between your toes and the bottoms of your feet.

If possible, having a partner can be helpful. Your partner can examine hard-to-see areas like your scalp and back.

Getting in the habit of checking your skin will help you notice changes. Checking monthly can be beneficial. If you have had skin cancer, your dermatologist can tell you how often you should check your skin.

People of all ages get skin cancer

Checking your skin can help you find skin cancer early when its highly treatable.

Symptoms Of Skin Cancer

Skin Cancer Symptoms that you Should Look Out for Include

  • Unusual skin moles, bumps, sores, blemishes and markings. Skin cancer makes your skin change in looks and feel. Sores due to skin cancer heal with difficulty or not at all.
  • A spot on your skin that changes its color, shape and size. The color may be seen spreading to nearby skin areas too.
  • A spot on your skin that is different from other spots. This is called the ugly duckling sign.

A rule called the ABCDE rule is applied in assessing skin spots for their likelihood to be cancerous. It checks for Asymmetry, Border irregularities, Color variations, Diameter of the spot and Evolution of skin spots and moles.

It is very important that you tell your doctor about new spots on your skin and any changes you note in the old ones. You should also have your doctor examine the areas of your skin that you cannot see yourself.

Should I Have Routine Skin Cancer Screenings

Skin Cancer Vs Mole

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

What Should You Look For

You should be on the lookout for any unusual spots on your skin. One study found more than 40 percent of melanomas are discovered by patients themselves, according to the American Cancer Society .

Regular self-exams can help you spot new growths or changes. Many doctors recommend performing these checks once a month.

Its best to examine your skin in a well-lit room in front of a full-length mirror. You can use a handheld mirror for harder-to-see areas, like the back of your thighs.

Be sure to look at all areas of your skin, including your palms, soles, ears, scalp, nails, and your back. If you cant see these spots, ask a family member or friend to help you.

Look for any lesions that are new or have changed in size, shape, color, or texture. Any sore, lump, or blemish that looks or feels unusual may also be a warning sign. Some skin cancers may appear as red, scaly, crusty, or swollen, and they may ooze or bleed. They can be painful, itchy, or tender.

According to, signs of melanoma may include a spot that:

  • Is asymmetrical
  • Has an irregular, blurred, or ragged border
  • Includes different shades of brown or black, or sometimes patches of pink, red, white, or blue
  • Is larger than 6 millimeters in diameter
  • Changes in shape, size, or color

Why Is An Early Diagnosis Important

Skin cancer is the most common type of cancer that affects Americans. One in five people in the United States will develop some type of skin cancer by the time they reach age 70.

The good news is early detection of all types of skin cancers, including basal cell carcinoma, squamous cell carcinoma, and melanoma, can greatly improve your chances of being cured.

Additionally, catching a skin cancer early on could make treatments easier. Smaller, simpler lesions are easier to remove surgically and less likely to result in scarring or disfigurement.

Its important to pay attention to new or changing skin spots and see your doctor if you notice anything out of the ordinary, notes the ACS.

What Are The Signs Of Symptoms Of Metastatic Melanoma

Signs and symptoms depend upon the site of metastasis and the amount of tumor there. Metastases to the brain may first appear as headaches, unusual numbness in the arms and legs, or seizures. Spread to the liver may be first identified by abnormal blood tests of liver function long before the patient has jaundice, a swollen liver, or any other signs of liver failure. Spread to the kidneys may cause pain and blood in the urine. Spread to the lungs may cause shortness of breath, other trouble breathing, chest pain, and continued cough. Spread to bones may cause bone pain or broken bones called pathologic fractures. A very high tumor burden may lead to fatigue, weight loss, weakness and, in rare cases, the release of so much melanin into the circulation that the patient may develop brown or black urine and have their skin turn a diffuse slate-gray color. The appearance of multiple blue-gray nodules in the skin of a melanoma patient may indicate widespread melanoma metastases to remote skin sites.

Blood Tests For Skin Cancer

How to Diagnose Skin Cancer | Skin Cancer

Skin cancer is a fairly common cancer type. It accounts for nearly 40% of all cancer cases. The three types of skin cancer are basal cell carcinoma, squamous cell carcinoma and malignant melanoma skin cancers. Melanoma cancers cause the most deaths resulting from skin cancer. This is because melanomas tend to spread to nearby tissue and other parts of the body. Diagnosis of skin cancer is done in a medical facility through physical examination, imaging tests, tissue biopsy and blood tests for skin cancer. Skin cancer is highly treatable with early detection.

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.

Blood Cell Count And Blood Chemistry

These two blood tests for cancer are done when you have advanced melanoma skin cancer. They help your doctor understand how well the kidneys, bone marrow and liver are working as you undergo treatment.

Recent medical advances point towards nucleic acid tests for blood cancer. In 2013, results of a study showed that measuring levels of specific chemically tagged genes could inform doctors on whether a melanoma sin cancer has started spreading. In separate research findings by cancer scientists in the United Kingdom, it is possible to predict the return of aggressive skin cancer by testing the blood of skin cancer patients. At their tests, the scientists checked the blood from these patients for tumor DNA.

How to Be Smarter About Skin Cancer

Skin cancer may form in basal cells or squamous cells. Basal cell carcinoma and squamous cell carcinoma are the most common types of skin cancer. They are also called nonmelanoma skin cancer. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.

Melanoma is less common than basal cell carcinoma or squamous cell carcinoma. It is more likely to invade nearby tissues and spread to other parts of the body.

This summary is about basal cell carcinoma, squamous cell carcinoma of the skin, and actinic keratosis. See the following PDQ summaries for information on melanoma and other kinds of cancer that affect the skin:

Skin Color And Being Exposed To Sunlight Can Increase The Risk Of Basal Cell Carcinoma And Squamous Cell Carcinoma Of The Skin

Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk.

Risk factors for basal cell carcinoma and squamous cell carcinoma of the skin include the following:

  • Being exposed to natural sunlight or artificial sunlight over long periods of time.
  • Having a fair complexion, which includes the following:
  • Fair skin that freckles and burns easily, does not tan, or tans poorly.
  • Blue, green, or other light-colored eyes.
  • Red or blond hair.

Although having a fair complexion is a risk factor for skin cancer, people of all skin colors can get skin cancer.

  • Having a history of sunburns.
  • Having a personal or family history of basal cell carcinoma, squamous cell carcinoma of the skin, actinic keratosis, familial dysplastic nevussyndrome, or unusual moles.
  • Having certain changes in the genes or hereditary syndromes, such as basal cell nevus syndrome, that are linked to skin cancer.
  • Having skin inflammation that has lasted for long periods of time.
  • Having a weakened immune system.
  • Being exposed to arsenic.
  • Past treatment with radiation.
  • Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.

    What Newer Tools Are Available To Diagnose Skin Cancer

    Some newer devices allow doctors to spot problematic skin lesions.

    One approach, called reflectance confocal microscopy , uses a low-power laser to scan skin lesions and provide important clues about whether theyre cancerous or not. RCM is sometimes used in combination with another method called optical coherence tomography , notes the Memorial Sloan Kettering Cancer Center.

    3D total body photography is another new technology thats used to track changes in the appearance of moles or lesions in people at risk for melanoma. Dozens of digital cameras snap pictures of patients simultaneously. Then a computer creates a 3D avatar to show all the lesions on an individuals body, so doctors can inspect them further.

    Skin cancer apps are also becoming popular detection devices. These apps, available via most smartphones, claim to assess skin changes and help people decide whether they should see their dermatologist. While they can be helpful at promoting awareness, the accuracy of these programs is questionable. One recent study found the most accurate skin cancer detection app missed nearly 30 percent of melanomas, per the Roswell Park Comprehensive Cancer Center.

    Can Melanoma Be Prevented

    You cant control how fair your skin is or whether you have a relative with cancerous moles. But there are things you can do to lower your risk of developing melanoma. The most important is limiting your exposure to the sun.

    Take these precautions:

    • Avoid the strongest sun of the day between 10 a.m. and 4 p.m.
    • Use broad-spectrum sunscreen whenever youre in the sun.
    • Wear a wide-brimmed hat and cover up with long, loose cotton clothing if you burn easily.
    • Stay out of the tanning salon. Even one indoor tanning session increases your risk of getting melanoma.

    Also, be sure to check your moles often . Keep dated records of each moles location, size, shape, and color, and get anything suspicious checked out right away.

    Not all skin cancer is melanoma, but every case of melanoma is serious. So now that you know more about it, take responsibility for protecting yourself and do what you can to lower your risk.

    Skin Cancer Is A Disease In Which Malignant Cells Form In The Tissues Of The Skin

    The skin is the bodys 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.
    • Basal cells: Round cells under the squamous cells.
    • Melanocytes: Cells that make melanin and are found in the lower part of the epidermis. Melanin is the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to darken.

    Skin cancer can occur anywhere on the body, but it is most common in skin that is often exposed to sunlight, such as the face, neck, and hands.
