After Skin Cancer Treatment

How many different types of cancer are there?

Most skin cancer is cured surgically in the dermatologist’s office. Of skin cancers that do recur, most do so within three years. Therefore, follow up with your dermatologist as recommended. Make an appointment immediately if you suspect a problem.

If you have advanced malignant melanoma, your oncologist may want to see you every few months. These visits may include total body skin exams, regional lymph node checks, and periodic chest X-rays and body scans. Over time, the intervals between follow-up appointments will increase. Eventually these checks may be done only once a year.

What Is Squamous Cell Carcinoma Of The Skin

Squamous cells are found throughout the human body. These cells line organs, such as the lungs, throat, and thyroid. We also have squamous cells in our skin.

The job of squamous cells is to protect what lies beneath. In our skin, these cells sit near the surface, protecting the tissue beneath.

Anywhere we have squamous cells, we can develop a type of cancer called squamous cell carcinoma .

In the skin, this cancer is usually not life-threatening. It tends to grow slowly, but it can grow deep. When the cancer grows deep, it can injure nerves, blood vessels, and anything else in its path. As the cancer cells pile up, a large tumor can form.

Most people who develop this skin cancer have fair skin that they seldom protected with sunscreen or sun-protective clothing. Before developing this skin cancer, they tend to notice signs of sun damage on their skin, such as age spots, patches of discolored skin, and deep wrinkles.

Anyone can develop squamous cell carcinoma

While anyone can develop this skin cancer, you have a greater risk if you live with a transplanted organ, use tanning beds, or have fair skin that you seldom protected from the sun.

Another sign of sun-damaged skin is having one or more pre-cancerous growths on your skin called actinic keratoses . Some AKs progress, turning into squamous cell carcinoma of the skin.

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:

Ways To Prevent Skin Cancer

Most cases of skin cancer are preventable. You can reduce your risk of getting skin cancer by following these safety tips:

  • Cover up.;When the UV Index is 3 or higher, protect your skin as much as possible. Wear light-coloured, long-sleeved shirts, pants, and a wide-brimmed hat made from breathable fabric. When you buy;sunglasses, make sure they provide protection against both UVA and UVB rays.
  • Limit your time in the sun. Keep out of the sun and heat between 11 a.m. and 3 p.m. The UV index in Canada can be 3 or higher during those times. When your shadow is shorter than you, the sun is very strong. Look for places with lots of shade, like a park with big trees, partial roofs, awnings, umbrellas or gazebo tents. Always take an umbrella to the beach.
  • Use sunscreen.;Put;sunscreen;on when the UV index is 3 or higher. Use sunscreen labelled broad spectrum and water resistant with an SPF of at least 30.
  • Avoid using;tanning equipment. There is no such thing as a healthy tan.; Using tanning equipment damages your skin and increases your risk of developing melanoma, the deadliest form of skin cancer.

Melanoma: The Deadliest Skin Cancer

Do you know all of the different types of skin cancers and ...

Melanoma is the most serious type of skin cancer, because it tends to spread if its not treated early.

This cancer starts in the melanocytes cells in the epidermis that make pigment.

About 100,350 new melanomas are diagnosed each year.

Risk factors for melanoma include:

  • Having fair skin, light eyes, freckles, or red or blond hair
  • Having a history of blistering sunburns
  • Being exposed to sunlight or tanning beds
  • Living closer to the equator or at a higher elevation
  • Having a family history of melanoma
  • Having many moles or unusual-looking moles
  • Having a weakened immune system

Melanoma can develop within a mole that you already have, or it can pop up as a new dark spot on your skin.

This cancer can form anywhere on your body, but it most often affects areas that have had sun exposure, such as the back, legs, arms, and face. Melanomas can also develop on the soles of your feet, palms of your hands, or fingernail beds.

Signs to watch out for include:

  • A mole that changes in color, size, or how it feels
  • A mole that bleeds

Taking Care Of Yourself

After you’ve been treated for basal cell carcinoma, you’ll need to take some steps to lower your chance of getting cancer again.

Check your skin. Keep an eye out for new growths. Some signs of cancer include areas of skin that are growing, changing, or bleeding. Check your skin regularly with a hand-held mirror and a full-length mirror so that you can get a good view of all parts of your body.

Avoid too much sun. Stay out of sunlight between 10 a.m. and 2 p.m., when the sun’s UVB burning rays are strongest.

Use sunscreen. The suns UVA rays are present all day long — thats why you need daily sunscreen. Make sure you apply sunscreen with at least a;6% zinc oxide and a sun;protection factor of 30 to all parts of the skin that aren’t covered up with clothes every day. You also need to reapply it every 60 to 80 minutes when outside.

Dress right. Wear a broad-brimmed hat and cover up as much as possible, such as long-sleeved shirts and long pants.

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.

Exams And Tests For Skin Cancer

If you think a mole or other skin lesion has turned into skin cancer, 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. Tests for skin cancer may include:

  • The doctor may use a handheld device called a dermatoscope to scan the lesion. Another handheld device, MelaFind, scans the lesion then a computer program evaluates images of the lesion to indicate if it’s cancerous.
  • A sample of skin will be taken so that the suspicious area of skin can be examined under a microscope.
  • A biopsy is;done in the dermatologist’s office.

If a biopsy shows that you have malignant melanoma, you may 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. This is only needed if the melanoma is of a certain size.

Most Dangerous Skin Cancer

Different Types of Skin Cancer | Skin Cancer

There are three primary types of skin cancer. The most serious is melanoma. Like all body tissues our skin is made up of cells: basal cells, squamous cells and melanocytes.

The various types of skin cancer are called for the skin cell where the cancer develops: basal cell carcinoma, squamous cell cancer and melanoma. Cancer is another word for cancer. Basal cell and squamous cell cancers are often grouped together and called common skin cancers.

Basal Cell Carcinoma: The Most Common Skin Cancer

Basal cell carcinoma, which is also called basal cell skin cancer, is the most common form of skin cancer, accounting for about 80 percent of all cases.

Rates of basal cell carcinoma have been increasing. Experts believe this is due to more sun exposure, longer lives, and better skin cancer detection methods.

This type of cancer begins in the skins basal cells, which are found in the outermost layer, the epidermis. They usually develop on areas that are exposed to the sun, like the face, head, and neck.

Basal cell carcinomas may look like:

  • A flesh-colored, round growth
  • A pinkish patch of skin
  • A bleeding or scabbing sore that heals and then comes back

They typically grow slowly and dont spread to other areas of the body. But, if these cancers arent treated, they can expand deeper and penetrate into nerves and bones.

Though its rare, basal cell carcinoma can be life-threatening. Experts believe that about 2,000 people in the United States die each year from basal cell carcinoma or squamous cell carcinoma.

Some risk factors that increase your chances of having a basal cell carcinoma include:

  • Being exposed to the sun or indoor tanning
  • Having a history of skin cancer
  • Being over age 50
  • Having chronic infections, skin inflammation, or a weakened immune system
  • Being exposed to industrial compounds, radiation, coal tar, or arsenic
  • Having an inherited disorder, such as nevoid basal cell carcinoma syndrome or xeroderma pigmentosum

What Is The Staging For Skin Cancer

There is no specific staging system for basal cell carcinoma. If the tumor is wider than 2 cm , it is probably a more serious tumor. Basal cell carcinomas of the ears, nose, and eyelid may also be of more concern, regardless of the size.

There is a staging system for squamous cell carcinoma. Large tumors that are thicker than 2 mm, invade the nerve structures of the skin, occur on the ear, and have certain worrisome characteristics under the microscope are of more concern. If the tumor metastasizes to a site at some distance from the primary tumor, the cancer is likely to be a dangerous tumor.

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.

How to Detect the Different Types of Skin Cancer

Basal Cell Carcinoma

BCC is the most common type of skin cancer and has a predilection for sun-exposed skin. Tumors may appear as a pearly or waxy bumps usually with visible blood vessels , or as a flat scaly reddish patch with a brown border, or as a hard or scar-like lesion . Frequently BCCs can be itchy, often bleed, or in more advanced cases, ulcerate.

Three Most Common Skin Cancers

It is estimated that one in seven people in the United States will develop some form of skin cancer during their lifetime. Although anyone can get skin cancer, people who burn easily and are fair-skinned are at higher risk. Researchers believe that one serious sunburn can increase the risk of skin cancer by as much as 50%. A yearly skin exam by a doctor is the best way to detect skin cancer early, when it is most treatable. If you have a new growth or any change in your skin, be sure to see your doctor to have it examined. Remember, protecting yourself from the sun is the best way to prevent all forms of skin cancer.

Squamous Cell Carcinoma Causes

Exposure to ultraviolet rays, like the ones from the sun or a tanning bed, affects the cells in the middle and outer layers of your skin and can cause them to make too many cells and not die off as they should. This can lead to out-of-control growth of these cells, which can lead to squamous cell carcinoma.

Other things can contribute to this kind of overgrowth, too, like conditions that affect your immune system.

Squamous Cell Carcinoma Treatment

Squamous cell carcinoma can usually be treated with minor surgery that can be done in a doctors office or hospital clinic. Depending on the size and location of the SCC, your doctor may choose different techniques to remove it.

For small skin cancers:

  • Curettage and electrodessication : removing the top layer of the skin cancer then using an electronic needle to kill cancer cells
  • Laser therapy: an intense light destroys the growth
  • : a photosensitizing solution applied to your skin then activated with a light or daylight, or sometimes with intense pulsed light
  • Cryosurgery: freezing of the spot using liquid nitrogen

For larger skin cancers:

  • Excision: cutting out the cancer spot and some healthy skin around it, then stitching up the wound
  • Mohs surgery: excision and then inspecting the excised skin using a microscope; this requires stitching up the wound

Squamous Cell Carcinoma: Common In Sun

Are there different types of skin cancer?

Squamous cell carcinoma, also called squamous cell cancer, is the second most common type of skin cancer. It accounts for about 20 percent of cases.

This type of cancer starts in flat cells in the outer part of the epidermis. It commonly crops up on sun-exposed areas, such as the face, ears, neck, lips, and hands. It can also develop on scars or chronic sores.

Squamous cell carcinomas may develop from precancerous skin spots, known as actinic keratosis .

These cancers might look like:

  • A firm, red bump
  • A flat lesion with a scaly, crusted surface
  • A sore that heals and then reopens

People with lighter skin are more at risk for developing squamous cell carcinoma, but the skin cancer can also affect those with darker skin.

Other risk factors include:

  • Having light eyes, blond or red hair, or freckles
  • Being exposed to the sun or tanning beds
  • Having a history of skin cancer
  • Having a history of sunburns
  • Having a weakened immune system
  • Having the genetic disorder xeroderma pigmentosum

What Exactly Is Cutaneous T

Cutaneous T-cell lymphoma is a rare type of blood cancer.

It begins in a type of white blood cell called the T-lymphocyte . T-cells help prevent infections and other diseases.

As odd as it sounds, most T-cells are found in our skin. Thats because our skin is the first line of defense against disease. The surface of an adults skin contains about 20 billion T-cells. Thats nearly twice as many T-cells as found in other parts of the body.

There are many types of CTCL. More than half the people who develop CTCL will have one of the following types:

  • Mycosis fungoides

  • Sézary syndrome

Mycosis fungoides is the most common type of CTCL. This type tends to worsen very slowly. It can stay in its earliest stage, which often looks like rash, for years. In this stage, the cancer is often difficult to diagnose because it tends to looks like eczema or psoriasis. These conditions are much more common than CTCL.

Sézary syndrome is more aggressive. It can also look like eczema. Some people develop red and swollen skin over much of their body. Their skin may feel hot, sore, and extremely itchy.

The other types of CTCL are very rare.

Cutaneous T-cell lymphoma is rare

The most common type of Cutaneous T-cell lymphoma often looks like a rash and develops on skin that gets little sunlight.

If you are diagnosed with CTCL, you may receive care from a team of doctors and other health care specialists. This team may include a dermatologist, hematologist , oncologist , and radiation oncologist .

Rarer Types Of Non Melanoma Skin Cancer

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. ;
