Where Is Skin Cancer Most Common On The Body

What Age Does Skin Cancer Commonly Develop

Some Basal Cell Skin Cancers Aggressive

The older you get, the higher your chance for developing skin cancer. About half of all Americans will develop either BCC or SCC at least once by the time theyre 65. The average age of a melanoma diagnosis is 63, notes the American Cancer Society.

But melanoma is also one of the most frequently occurring cancers in young adults, especially women. Overall, melanoma occurs more frequently in women than in men before age 50. By age 65, twice as many men than women have melanoma. Rates triple by age 80.

Long-term exposure to the suns UV rays increases a persons chances of developing skin cancer. Artificial UV light, as found in indoor tanning beds, is also a culprit. It accounts for approximately of skin cancer each year in the United States, estimates a 2014 review and meta-analysis.

The Skin Cancer Foundation goes on to report that indoor tanning beds account for:

  • 245,000 cases of BCC
  • 168,000 cases of SCC
  • 6,200 cases of melanoma

Any history of tanning bed use increases the risk of BCC before age 40 by 69 percent.

Although were more educated and aware of skin cancer risks, the number of new cases has been climbing for 30 years even among younger Americans. In the United States, cases of BCC and SCC among men and women under age 40 are increasing. New cases in children are also on the rise.

Where Scc Usually Occurs

Squamous cell carcinoma typically shows up on areas of the skin that are exposed to the sun, such as the face, ears, lips, arms, legs and tops of hands, but it can also more rarely appear on areas not exposed to the sun including the lower lip, genitals, in the lining of organs and the passages of the respiratory and digestive tracts.

The Most Common Skin Cancer

Basal cell carcinoma is the most common form of skin cancer and the most frequently occurring form of all cancers. In the U.S. alone, an estimated 3.6 million cases are diagnosed each year. BCCs arise from abnormal, uncontrolled growth of basal cells.

Because BCCs grow slowly, most are curable and cause minimal damage when caught and treated early. Understanding BCC causes, risk factors and warning signs can help you detect them early, when they are easiest to treat and cure.

Treatment Options For Skin Cancer

The goal of any skin cancer treatment is to remove the cancer before it has a chance to spread. If the skin cancer has spread to nearby tissues or organs, treating the cancer becomes more difficult. If it hasnt spread, though, treating skin cancer is often very successful.

Treatment options include:

  • Surgery. Surgically removing the cancerous spot is a common option. In some cases, the spot can be removed easily in a doctors office. More advanced cases may require in-depth surgery.
  • Cryosurgery. This type of surgery freezes the affected skin, killing the cancerous cells. Over time, the dead skin cells fall off.
  • Immunotherapy. Immunotherapy uses a persons immune system to target and destroy cancer. In the case of skin cancer, a medicated cream is applied to the cancerous area. The immune system then works to destroy the cancer.
  • Chemotherapy. If skin cancer has progressed beyond the skin, chemotherapy can help target and kill any cancer cells surgery cant remove. Chemotherapy comes in several forms, including oral medication, injected shots, and IV infusions. It can even be applied to the skin.
  • Radiation therapy. Radiation seeks out and destroys cancer cells. Radiation is used to treat a larger area, or an area thats too difficult to treat with surgery.
  • In this type of therapy, a chemical is applied to the skin cancer. After staying on the skin for many hours, the skin is exposed to a special light, destroying the cancer cells.

Skin Cancer 101: A review of the 3 most common skin cancers

Cancers of the skin specifically, basal cell carcinoma and squamous cell carcinoma are by far the most common types of cancer. However, when detected in early stages, skin cancer can often be effectively treated and even cured, so its important to regularly check your skin and promptly discuss any unusual changes with a physician.

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

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.

Treatment Options Skin Cancer Surgery & Other Options

Mole removal is an important part of early skin cancer treatment and there are several methods for removing moles. The less invasive ones are radiofrequency mole removal and cryotherapy mole removal. In the former, concentrated radiofrequencies are used to shave off raised unharmful moles. Cryotherapy involves freezing off moles. There are also forms of skin cancer surgery such as excision, punch excision and shaving.

The Second Most Common Skin Cancer

Squamous cell carcinoma of the skin is the second most common form of skin cancer, characterized by abnormal, accelerated growth of squamous cells. When caught early, most SCCs are curable.

SCC of the skin is also known as cutaneous squamous cell carcinoma . Adding the word cutaneous identifies it as a skin cancer and differentiates it from squamous cell cancers that can arise inside the body, in places like the mouth, throat or lungs.

The Most Common Type Of Skin Cancer

What skin cancer looks like

Basal cell carcinoma is the most common type of skin cancer and it typically looks like a pearly or waxy bump, a flesh-colored growth, or a bleeding sore.

These most frequently appear on fair-skinned people after years of frequent exposure to the sun. Theyre most commonly found on sun-exposed areas like the head, neck or arms.

Basal cell carcinoma accounts for more than 80 percent of skin cancer cases.

If left untreated, basal cell carcinoma can penetrate nerves and bones, causing damage and disfigurement.

How Common Is Skin Cancer

You may think places with sunnier, hotter weather have more cases of skin cancer. This isnt necessarily the case. In fact, the Centers for Disease Control and Prevention notes California and Florida had fewer cases per 100,000 people than states with cooler climates, like Wyoming, Montana, and Idaho, in 2015.

The states with the fewest cases of skin cancer are:

  • Alaska
  • Wyoming

Knowledge Is Your Best Defense

What Is Skin Cancer?

Skin cancer is the out-of-control growth of abnormal cells in the epidermis, the outermost skin layer, caused by unrepaired DNA damage that triggers mutations. These mutations lead the skin cells to multiply rapidly and form malignant tumors. The main types of skin cancer are basal cell carcinoma , squamous cell carcinoma , melanoma and Merkel cell carcinoma .

The two main causes of skin cancer are the suns harmful ultraviolet rays and the use of UV tanning beds. The good news is that if skin cancer is caught early, your dermatologist can treat it with little or no scarring and high odds of eliminating it entirely. Often, the doctor may even detect the growth at a precancerous stage, before it has become a full-blown skin cancer or penetrated below the surface of the skin.

Americans will develop skin cancer by age 70.

What Are The Symptoms Of Skin Cancer

Symptoms of skin cancer can be easily confused and are often overlooked if you have a history of noncancerous moles, freckles, or growths.

However, any change on your skin could be a potential cancer. Knowing the additional symptoms of skin cancer will help you know whether youre in the clear or need to book an appointment with your doctor.

Rarer Types Of Non Melanoma Skin Cancer

PPT

There are other less common types of skin cancer. These include:

  • Merkel cell carcinoma
  • T cell lymphoma of the skin
  • Sebaceous gland cancer

These are all treated differently from basal cell and squamous cell skin cancers.

Merkel cell carcinoma

Merkel cell carcinoma is very rare. Treatment is with surgery or radiotherapy, or both. This usually works well, but sometimes the cancer can come back in the same place. And sometimes it spreads to nearby lymph nodes.

Sebaceous gland cancer

Sebaceous gland cancer is another rare type of skin cancer affecting the glands that produce the skin’s natural oils. Treatment is usually surgery for this type of cancer.

Kaposi’s sarcoma

Kaposis sarcoma is a rare condition. It’s often associated with HIV but also occurs in people who don’t have HIV. It’s a cancer that starts in the cells that form the lining of lymph nodes and the lining of blood vessels in the skin. Treatment is surgery or radiotherapy, and sometimes chemotherapy.

T cell lymphoma of the skin

T cell lymphoma of the skin can also be called primary cutaneous lymphoma. It’s a type of non Hodgkin lymphoma. There are a number of different types of treatment for this type of cancer.

Cancer May Spread From Where It Began To Other Parts Of The Body

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began and travel through the lymph system or blood.

  • Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor in another part of the body.
  • Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if skin cancer spreads to the lung, the cancer cells in the lung are actually skin cancer cells. The disease is metastatic skin cancer, not lung cancer.

Signs And Symptoms Of Melanoma

The most common sign of melanoma is the appearance of a new mole or a change in an existing mole.

This can happen anywhere on the body, but the most commonly affected areas are the back in men and the legs in women.

Melanomas are uncommon in areas that are protected from sun exposure, such as the buttocks and the scalp.

In most cases, melanomas have an irregular shape and are more than 1 colour.

The mole may also be larger than normal and can sometimes be itchy or bleed.

Look out for a mole that gradually changes shape, size or colour.

Superficial spreading melanoma are the most common type of melanoma in the UK.

They’re more common in people with pale skin and freckles, and much less common in people with darker skin.

They initially tend to grow outwards rather than downwards, so they do not pose a problem.

But if they grow downwards into the deeper layers of skin, they can spread to other parts of the body.

You should see a GP if you have a mole that’s getting bigger, particularly if it has an irregular edge.

Screening For Skin Cancer

Again, the best way to screen for skin cancer is knowing your own skin. If you are familiar with the freckles, moles, and other blemishes on your body, you are more likely to notice quickly if something seems unusual.

To help spot potentially dangerous abnormalities, doctors recommend doing regular self-exams of your skin at home. Ideally, these self-exams should happen once a month, and should involve an examination of all parts of your body. Use a hand-held mirror and ask friends or family for help so as to check your back, scalp, and other hard-to-see areas of skin. If you or someone else notices a change on your skin, set up a doctors appointment to get a professional opinion.

Where Melanoma Usually Occurs

Can you spot skin cancer? Keep an eye out for these warning signs

Melanoma can occur anywhere on the body, including areas not exposed to the sun, like inside the mouth or the palms of the hands. Men are more likely to get melanomas on their back and trunk or on their head and neck while women are more likely to get them on their arms and legs.

A study in the Journal of American Academy of Dermatology found that melanomas in blacks, Asians, Filipinos, Indonesians, and native Hawaiians most often occur on non-exposed skin with less pigment, with up to 60-75 percent of tumors arising on the palms, soles, mucous membranes and nail regions.

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.

    How Is Skin Cancer Treated

    Treatment depends upon the stage of the cancer. Some types of treatment include the following:

    • Surgery
    • Mohs micrographic surgery uses a scalpel to remove the tumor and thin layer of surrounding tissue.
    • Excisional surgery involves a surgeon removing the tumor and some predetermined amount of surrounding healthy skin to be sure all cancer has been removed.
    • Electrosurgery uses heat to burn the tumor and some surrounding area.
    • Cryosurgery involves freezing the tumor and may require multiple treatments.
  • Topical chemotherapy/immunotherapy is sometimes used to treat certain skin cancers or precancerous lesions.
  • Radiation therapy
  • Additional medical therapy or radiation therapy may be recommended if the cancer has a high risk of coming back in the same place or spreading beyond the skin to internal organs. If the cancer spreads beyond the skin to other organs or surrounding tissue, chemotherapy, targeted drug therapy, or immune therapy is often used.
  • Radiation therapy or topical therapy can be used for cancers in places that are hard to reach with surgery or for patients who are not able to have surgery.

    What Is The Treatment For Skin Cancer

    Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy or immunotherapy or both. Because of the complexity of treatment decisions, people with malignant melanoma may benefit from the combined expertise of the dermatologist, a cancer surgeon, and a medical oncologist.

    Can Skin Cancer Be Prevented

    Home Remedies for Skin Cancer

    In most cases, skin cancer can be prevented. The best way to protect yourself is to avoid too much sunlight and sunburns. Ultraviolet rays from the sun damage the skin, and over time lead to skin cancer.

    Here are ways to protect yourself from skin cancer:

    • Seek shade. Don’t spend long periods of time in direct sunlight.
    • Wear hats with wide brims to protect your face and ears.
    • Wear long-sleeved shirts and pants to protect your arms and legs.
    • Use broad-spectrum sunscreens with an SPF of 30 or higher that protect against burning and tanning rays. Apply the sunscreen 30 minutes before you go outside.
    • Wear sunglasses to protect your eyes.
    • Use a lip balm with sunscreen.
    • Avoid the sun between 10:00 a.m. and 4:00 p.m.
    • Show any changing mole to your healthcare provider.

    What Is The Outlook For People With Skin Cancer

    Nearly all skin cancers can be cured if they are treated before they have a chance to spread. The earlier skin cancer is found and removed, the better your chances for a full recovery. Ninety percent of those with basal cell skin cancer are cured. It is important to continue following up with a doctor to make sure the cancer does not return. If something seems wrong, call a doctor right away.
