What Does Skin Cancer Do

The Early Stages Of Skin Cancer

Some forms of cancer, especially melanoma, may appear suddenly and without warning. Most people become alarmed only when they develop a crust or sore that refuses to heal. Did you know that the early stages of cancer do not always look or feel so bad? Harmless-looking moles, skin lesions, or unusual skin growths may also be the signs of early stages.

Regular skin examination can help you spot these early clues. If you see anything suspicious or observe unusual appearances in your skin, we can help you get the right diagnosis and treatment immediately. Some forms of cancer in the skin can be life-threatening and spread without being given urgent attention.

Less Common Skin Cancers

Uncommon types of skin cancer include Kaposi’s sarcoma, mainly seen in people with weakened immune systems sebaceous gland carcinoma, an aggressive cancer originating in the oil glands in the skin and Merkel cell carcinoma, which is usually found on sun-exposed areas on the head, neck, arms, and legs but often spreads to other parts of the body.

What Makes Yale Medicines Approach To Squamous Cell Carcinoma Unique

Simple, small cancers can often be treated very well by a local dermatologist, according to Dr. Leffell. We rarely see the small cancers. We get referred to the cases that need special attention.

Dr. Leffell emphasizes that at Yale Medicine, the patient always comes first. We like to have a discussion with the patient about what happens after the skin cancer is removed, he says. We talk about what’s involved with plastic surgery and what’s involved with letting the area heal naturally. We prefer to take a minimalist approach and let the patient decide what they want us to do and how they want to let their skin heal.

If the decision is made to repair the wound using plastic surgery, we do that immediately in the office setting, Dr. Leffell says. Alternatively, allowing the wound to heal naturally is often a great option, and does not rule out doing plastic surgery down the road if needed, though that is very rarely the case.

Squamous Cell Carcinoma Pictures

Squamous cell carcinoma also appears in areas most exposed to the sun and, as indicated in the pictures below, often presents itself as a scab or sore that doesnt heal, a volcano-like growth with a rim and crater in the middle or simply as a crusty patch of skin that is a bit inflamed and red and doesnt go away over time.

Any lesion that bleeds or itches and doesnt heal within a few weeks may be a concern even if it doesnt look like these Squamous cell carcinoma images.

How The Government Of Canada Protects You

The Public Health Agency of Canada monitors cancer in Canada. PHAC identifies trends and risk factors for cancer, develops programs to reduce cancer risks, and researches to evaluate risks from the environment and human behaviours. Health Canada also promotes public awareness about sun safety and the harmful effects of UV rays.

How Is Squamous Cell Skin Cancer Treated

Although squamous cell cancers usually grow slowly, it is important to see a dermatologist quickly. “The sooner you see your doctor and the cancer is diagnosed and treated, the less complicated the surgery to remove it will be, and the faster you will make a complete recovery, Dr. Leffell explains. The treatment for squamous cell cancer varies according to the size and location of the lesion. The surgical options are the same as those for basal cell cancer:

• Surgical excision: Removing a squamous cell lesion is a simple procedure that typically takes place in the dermatologist’s office. After numbing the cancer and the area around it with a local anesthetic, the doctor uses a scalpel to remove the tumor and some of the surrounding skin to make sure all cancer is eliminated. Estimating how much to take requires skill and expertise, Dr. Leffell notes. The risk of taking too little tissue is that some cancer remains taking too much leaves a larger scar than is necessary. Shaped like a football, the wound is stitched together, using plastic surgery techniques. If dissolvable stitches are used, they will disappear on their own as the area heals. Though the procedure leaves some redness and a small scar, it tends to become less noticeable over time. “The cure rate for this type of excision is typically about 90 to 93 percent,” says Dr. Leffell. But, of course, this is dependent on the skill and experience of the doctor.”

Curettage Electrodesiccation And Cryotherapy

Some dermatologists perform curettage, electrodesiccation, and cryotherapy to treat skin cancer. These are considered to be destructive techniques that are best suited for small, superficial carcinomas with definite borders. During the procedure, layers of skin cells are scraped away using a curette. Any remaining cancer cells are destroyed with the use of an electric needle.

In some cases, liquid nitrogen or cryotherapy is used to freeze the margins of the treatment area. Extremely low temperatures kill the malignant skin cells and create a wound, which will heal in a few weeks. The treatment may leave scars that are flat and round, similar to the size of the skin cancer lesion.

What Are The Symptoms Of Skin Cancer Of The Head And Neck

Skin cancers usually present as an abnormal growth on the skin. The growth may have the appearance of a wart, crusty spot, ulcer, mole or sore. It may or may not bleed and can be painful. If you have a preexisting mole, any change in the characteristics of this spot – such as a raised or an irregular border, irregular shape, change in color, increase in size, itching or bleeding – are warning signs of melanoma. Sometimes the first sign of melanoma or squamous cell cancer is an enlarged lymph node.

Major Types Of Skin Cancers And Their Distribution In People Of Color

Skin cancer is mainly divided into two main categories as Non melanoma Skin Cancer and Melanoma Skin Cancer . Non-Melanoma Skin Cancer includes basal cell carcinoma and squamous cell carcinoma . Each of these most common cancers viz. Basal cell carcinoma , squamous cell carcinoma , and melanoma is named after the type of skin cell from which it arises and has been linked to the varying degree of sun exposure .

NMSC greatly outnumber melanomas in incidence but fortunately most are much easier to treat and have much better long-term prognosis . They are less deadly than melanoma mainly due to their tendency to remain confined to their primary site of disease which makes their management much more straightforward. The devastating majority of keratinocyte malignancies progress in the areas of skin most exposed to UV such as on the face and arms . The BCC and the SCCs often carry a UV-signature mutation indicating that these cancers are caused by UV-B radiation via the direct DNA damage . Although Asians display relative protection from basal cell carcinoma and squamous cell carcinoma, incidence rates of these non melanoma skin cancers have been increasing over 3 to 8 percent annually in the past three decades . Features of different types of skin cancers are listed in .

Can Skin Cancer Be Prevented

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 Are The Risk Factors For Skin Cancer

People burn or tan depending on their skin type, the time of year, and how long they are exposed to UV rays.

Anyone can get skin cancer, but people with certain characteristics are at greater risk

• A lighter natural skin color.
• Skin that burns, freckles, reddens easily, or becomes painful in the sun.
• Blue or green eyes.
• Certain types and a large number of moles.
• A family history of skin cancer.
• A personal history of skin cancer.
• Older age.

Symptoms On Black And Brown Skin

On dark skin, it may be easier to feel a lesion than see it. People with black skin may be more likely to find a lesion on a part of the body that has little exposure to the sun, according to the American Academy of Dermatology.

Skin cancer can affect people with any skin color, but those with brown or black skin are more likely to receive a diagnosis at a later stage. This may be due to a lack of awareness of how skin cancer appears on skin colors other than white.

Anyone who notices an unusual change in their skin should seek medical advice as soon as possible.

The medical community has developed two ways to spot the early symptoms of melanoma. This is the most dangerous type of skin cancer.

A person can use the ABCDE method or the ugly duckling method.

The Four Major Types Of Melanoma

• superficial spreading melanoma: the most common type of melanoma lesions are usually flat, irregular in shape, and contain varying shades of black and brown it can occur at any age
• lentigo maligna melanoma: usually affects the elderly involves large, flat, brownish lesions
• nodular melanoma: can be dark blue, black, or reddish-blue, but may have no color at all it usually starts as a raised patch
• acral lentiginous melanoma: the least common type typically affects the palms, soles of the feet, or under finger and toenails

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.

Types Of Skin Malignancies:

• Melanoma the least common form of skin cancer, but responsible for more deaths per year than squamous cell and basal cell skin cancers combined. Melanoma is also more likely to spread and may be harder to control.
• Nonmelanoma malignancies:
• Squamous cell cancer the second-most common skin cancer. It’s more aggressive and may require extensive surgery, depending on location and nerve involvement.
• Basal cell cancer the most common form of skin cancer. It is rarely fatal but can be locally aggressive.

These skin malignancies are typically caused by ultraviolet radiation from exposure to the sun and tanning beds.

A Sore That Doesn’t Heal

Many skin cancers are first dismissed as being due to a bug bite, minor injury, or irritation, but become more obvious when they don’t go away over time. If you notice a sore on your skin that refuses to heal, even if it seems to be healing but then reappears, talk to your healthcare provider. In general, any skin change that hasn’t resolved on its own over a period of two weeks should be evaluated.

Basal Cell And Squamous Cell Skin Cancers

Basal cell and squamous cell cancers are by far the most common skin cancers, and actually are more common than any other form of cancer. Because they rarely spread to other parts of the body, basal cell and squamous cell skin cancers are usually less concerning and are treated differently from melanoma. These cancers are discussed in Basal and Squamous Cell Skin Cancer.

What Exams And Tests Diagnose Skin Cancer

If you have a worrisome mole or other lesion, your primary-care provider will probably refer you to a dermatologist. The dermatologist will examine any moles in question and, in many cases, the entire skin surface.

• Any lesions that are difficult to identify, or are thought to be skin cancer, may then be checked.
• A sample of skin will be taken so that the suspicious area of skin can be examined under a microscope.
• A biopsy can almost always be done in the dermatologist’s office.

If a biopsy shows that you have malignant melanoma, you will probably undergo further testing to determine the extent of spread of the disease, if any. This may involve blood tests, a chest X-ray, and other tests as needed.

See A Suspicious Spot See A Dermatologist

If you find a spot on your skin that could be skin cancer, its time to see a dermatologist. Found early, skin cancer is highly treatable. Often a dermatologist can treat an early skin cancer by removing the cancer and a bit of normal-looking skin.

Given time to grow, treatment for skin cancer becomes more difficult.

What Is Skin Cancer

Basal cell carcinoma begins in the basal cell layer of the skin. Squamous cell carcinoma begins in the squamous layer of the skin. Melanoma begins in the melanocytes, which are the cells that make melanin, the pigment that gives skin its color.

Basal cell carcinoma begins in the basal cell layer of the skin. Squamous cell carcinoma begins in the squamous layer of the skin. Melanoma begins in the melanocytes, which are the cells that make melanin, the pigment that gives skin its color.

The skin is the bodys largest organ. 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 color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to darken.

Basal and squamous cell carcinomas are the two most common types of skin cancer. They begin in the basal and squamous layers of the skin, respectively. Both can usually be cured, but they can be disfiguring and expensive to treat.

Basal Cell Carcinoma Stages

There are certain features that are considered to make the cancer at higher risk for spreading or recurrence, and these may also be used to stage basal cell carcinomas. These include:

• Greater than 2 mm in thickness
• Invasion into the lower dermis or subcutis layers of the skin
• Invasion into the tiny nerves in the skin
• Location on the ear or on a hair-bearing lip

After the TNM components and risk factors have been established, the cancer is given a stage. For basal cell carcinoma staging, the factors are grouped and labeled 0 to 4. The characteristics and stages of basal cell carcinoma are:

Stage 0: Also called carcinoma in situ, cancer discovered in this stage is only present in the epidermis and has not spread deeper to the dermis.

Stage 1 basal cell carcinoma: The cancer is less than 2 centimeters, about 4/5 of an inch across, has not spread to nearby lymph nodes or organs, and has one or fewer high-risk features.

Stage 2 basal cell carcinoma: The cancer is larger than 2 centimeters across, and has not spread to nearby organs or lymph nodes, or a tumor of any size with 2 or more high-risk features.

Stage 3 basal cell carcinoma: The cancer has spread into facial bones or 1 nearby lymph node, but not to other organs.

Stage 4 basal cell carcinoma: The cancer can be any size and has spread to 1 or more lymph nodes which are larger than 3 cm and may have spread to bones or other organs in the body.

What Are Possible Complications Of Skin Cancer In A Child

Possible complications depend on the type and stage of skin cancer. Melanoma is more likely to cause complications. And the more advanced the cancer, the more likely there will be complications.

Complications may result from treatment, such as:

• Loss of large areas of skin and underlying tissue

• Scarring

• Problems with the area healing

• Infection in the area

• Return of the skin cancer after treatment

Melanoma may spread to organs throughout the body and cause death.
