Are there different types of skin cancer?

Scientists dont fully know why people of skin with color develop cancer in non-sun-exposed areas, such as their hands and feet. They think that the sun is less of a factor though. However, dermatologists still see plenty of UV sunlight-induced melanomas and squamous cell skin cancer in people of color, in skin tones ranging from fair to very dark.

Lung Cancer Causes And Risk Factors

Cancer can develop when healthy cells in the body lose control and begin growing excessively. The cause for this may be hereditary, or a person can develop tumors due to outside forces. Risk factors for lung cancer include environments that a person may encounter that can raise the chances of their exposure to carcinogens, or cancer-causing agents.

If a person is exposed to a carcinogenic substance on a job site, prolonged exposure could increase that persons chances of developing lung cancer. In this case, their occupation would be considered a risk factor, while the carcinogenic substance is the potential cause. Asbestos, for example, is a harmful carcinogen that has been known to cause lung cancer and mesothelioma when a person is exposed to its toxic fibers for an extended period.

Recurrent Basal Cell Carcinoma

Basal cell carcinomas are the most common type of skin cancer, according to the American Cancer Society. These cancers develop within the basal cell layer of the skin, in the lowest part of the epidermis.

Patients who have had basal cell carcinoma once have an increased risk of developing a recurrent basal cell cancer. Basal cell cancers may recur in the same location that the original cancer was found or elsewhere in the body. As many as 50 percent of cancer patients are estimated to experience basal cell carcinoma recurrence within five years of the first diagnosis.

Basal cell carcinomas typically grow slowly, and it is rare for them to metastasize or spread to nearby lymph nodes or other parts of the body. But early detection and treatment are important.

After completing treatment for basal cell carcinoma, it is important to perform regular self-examinations of the skin to look for new symptoms, such as unusual growths or changes in the size, shape or color of an existing spot. Skin cancers typically develop in areas of the body that are exposed to the sun, but they may also develop in areas with no sun exposure. Tell your oncologist or dermatologist about any new symptoms or suspicious changes you may have noticed.

  • Have a history of eczema or dry skin
  • Have been exposed to high doses of UV light
  • Had original carcinomas several layers deep in the skin
  • Had original carcinomas larger than 2 centimeters

In Situ Vs Invasive Breast Cancers

The type of breast cancer can also refer to whether the cancer has spread or not. In situ breast cancer is a pre-cancer that starts in a milk duct and has not grown into the rest of the breast tissue. The term invasive breast canceris used to describe any type of breast cancer that has spread into the surrounding breast tissue.

Invasive breast cancer has spread into surrounding breast tissue. The most common types are invasive ductal carcinoma and invasive lobular carcinoma. Invasive ductal carcinoma makes up about 70-80% of all breast cancers.

When Should I See My Healthcare Provider

Spelling Out Skin Cancer

Make an appointment to see your healthcare provider or dermatologist as soon as you notice:

  • Any changes to your skin or changes in the size, shape or color of existing moles or other skin lesions.
  • The appearance of a new growth on your skin.
  • A sore that doesnt heal.
  • Spots on your skin that are different from others.
  • Any spots that change, itch or bleed.

Your provider will check your skin, take a biopsy , make a diagnosis and discuss treatment. Also, see your dermatologist annually for a full skin review.

What Is Nonmelanoma Skin Cancer

Skin cancer is a disease that begins in the cells of the skin. The area of skin with the cancer is often called a lesion. There are several types of skin cancer . Melanoma is the most serious. But there are others that are known as nonmelanoma skin cancer. These include:

  • Basal cell carcinoma

Basal cell carcinoma and squamous cell carcinoma are by far the most common.

How Many Types Of Cancer Are There

Cancer describes a group of diseases in which abnormal cells grow out of control.

Cancer is the second leading cause of death in the United States heart disease is the leading cause. In 2018, there were 599,274 cancer deaths in the U.S.

The American Cancer Society estimates the 5 most deadly cancers for 2020 in the U.S. are:

Other Types Of Non Clear Cell Kidney Cancer

  • Transitional cell carcinoma : They are also known as urothelial carcinomas. TCCs do not start in the kidney but in the transitional cells in the lining of the renal pelvis. This cancer can look like other types of urothelial cancer such as bladder cancer. However, people with TCC will often have the same symptoms as people with kidney cancer, like blood in the urine and back pain. TCC is rare and can be aggressive.
  • Wilms tumor : This tumor almost always occurs in children and is very rare in adults. About 90% of kidney cancers in children are Wilms tumors.
  • Renal sarcoma: This is a rare type of kidney cancer that begins in the blood vessels or connective tissue of the kidney.

Who Is Most At Risk For Skin Cancer

How many different types of cancer are there?

Although anyone can develop skin cancer, youre at increased risk if you:

  • Spend a considerable amount of time working or playing in the sun.
  • Get easily sunburned have a history of sunburns.
  • Live in a sunny or high-altitude climate.
  • Tan or use tanning beds.
  • Have light-colored eyes, blond or red hair and fair or freckled skin.

What Does Skin Cancer Look Like

Basal cell carcinoma

  • BCC frequently develops in people who have fair skin. People who have skin of color also get this skin cancer.

  • BCCs often look like a flesh-colored round growth, pearl-like bump, or a pinkish patch of skin.

  • BCCs usually develop after years of frequent sun exposure or indoor tanning.

  • BCCs are common on the head, neck, and arms however, they can form anywhere on the body, including the chest, abdomen, and legs.

  • Early diagnosis and treatment for BCC are important. BCC can grow deep. Allowed to grow, it can penetrate the nerves and bones, causing damage and disfigurement.

Squamous cell carcinoma of the skin

  • People who have light skin are most likely to develop SCC. This skin cancer also develops in people who have darker skin.

  • SCC often looks like a red firm bump, scaly patch, or a sore that heals and then re-opens.

  • SCC tends to form on skin that gets frequent sun exposure, such as the rim of the ear, face, neck, arms, chest, and back.

  • SCC can grow deep into the skin, causing damage and disfigurement.

  • Early diagnosis and treatment can prevent SCC from growing deep and spreading to other areas of the body.

SCC can develop from a precancerous skin growth

  • People who get AKs usually have fair skin.

  • AKs usually form on the skin that gets lots of sun exposure, such as the head, neck, hands, and forearms.

  • Because an AK can turn into a type of skin cancer, treatment is important.

Melanoma

How Is Skin Cancer Treated

Treatment depends upon the stage of cancer. Stages of skin cancer range from stage 0 to stage IV. The higher the number, the more cancer has spread.

Sometimes a biopsy alone can remove all the cancer tissue if the cancer is small and limited to your skins surface only. Other common skin cancer treatments, used alone or in combination, include:

Cryotherapy uses liquid nitrogen to freeze skin cancer. The dead cells slough off after treatment. Precancerous skin lesions, called actinic keratosis, and other small, early cancers limited to the skins top layer can be treated with this method.

Excisional surgery

This surgery involves removing the tumor and some surrounding healthy skin to be sure all cancer has been removed.

Mohs surgery

With this procedure, the visible, raised area of the tumor is removed first. Then your surgeon uses a scalpel to remove a thin layer of skin cancer cells. The layer is examined under a microscope immediately after removal. Additional layers of tissue continue to be removed, one layer at a time, until no more cancer cells are seen under the microscope.

Mohs surgery removes only diseased tissue, saving as much surrounding normal tissue as possible. Its most often used to treat basal cell and squamous cell cancers and near sensitive or cosmetically important areas, such as eyelids, ears, lips, forehead, scalp, fingers or genital area.

What Causes Skin Cancer

Skin Cancer Screening

The main cause of skin cancer is overexposure to sunlight, especially when it results in sunburn and blistering. Ultraviolet rays from the sun damage DNA in your skin, causing abnormal cells to form. These abnormal cells rapidly divide in a disorganized manner, forming a mass of cancer cells.

Another cause of skin cancer is frequent skin contact with certain chemicals, such as tar and coal.

Many other factors can increase your risk of developing skin cancer. See question, Who is most at risk for skin cancer?

Melanoma: The Deadliest Skin Cancer

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

Different Types Of Skin Cancer

On this page

The different types of skin cancer are named after the type of skin cell they start from. There are three main types of skin cancer:

  • basal cell carcinoma
  • squamous cell carcinoma of the skin
  • melanoma.

BCCs and SCCs are different from melanoma. They are called non-melanoma skin cancers.We have separate information about melanoma.

The skin does many things. It:

  • protects the body from injury and infection
  • helps to control body temperature
  • helps to control fluid loss
  • gets rid of waste substances through the sweat glands.

The skin is divided into 2 main layers. The outer layer is the epidermis and the layer underneath is the dermis. Below these is a deeper layer of fatty tissue.

The epidermis contains several types of cells. Most of the epidermis is filled with cells called keratinocytes, also called squamous cells.

The lowest layer of the epidermis is called the basal layer. It contains rounder cells called basal cells.

The basal layer also contains skin cells called melanocytes which produce melanin. Melanin gives skin its natural colour.

What Is The Outlook For People With Squamous Cell Cancer

Early detection of SCC is key to successful treatment. If SCC isnt treated in its early stages, the cancer may spread to other areas of the body, including the lymph nodes and organs. Once this occurs, the condition can be life threatening.

Those with weakened immune systems due to certain medical conditions, such as HIV, AIDS, or leukemia, have a greater risk of developing more serious forms of SCC.

Basic Information About Skin Cancer

Different Types of Skin Cancer | Skin Cancer

Cancer is a disease in which cells in the body grow out of control. When cancer starts in the skin, it is called skin cancer.

Skin cancer is the most common cancer in the United States. Some people are at higher risk of skin cancer than others, but anyone can get it. The most preventable cause of skin cancer is overexposure to ultraviolet light, either from the sun or from artificial sources like tanning beds.

Most skin cancers are caused by too much exposure to ultraviolet rays. To lower your risk of getting skin cancer, you can protect your skin from UV rays from the sun and from artificial sources like tanning beds and sunlamps.While enjoying the benefits of being outdoors, people can decrease skin cancer risk by using sun protection. Protect yourself by staying in the shade, wearing protective clothing, and applying and re-applying a broad spectrum sunscreen with a sun protection factor of 15 or higher.Links with this icon indicate that you are leaving the CDC website.

Other Types Of Skin Cancer

Unusual types of skin cancer include Merkel cell tumors. Merkel cell carcinoma starts when cells in the skin, also called Merkel cells, start to grow uncontrollably. This type of cancer can grow quickly and can be hard to treat if it spreads beyond the skin.

Dermatofibrosarcoma protuberans is another rare skin cancer that begins in the middle layer of skin, known as the dermis. This type of cancer tends to grow slowly and seldom spreads to other parts of the body.

What Happens If Basal Cell Carcinoma Is Left Untreated

Basal cell carcinoma is the most common type of skin cancer, and it is considered very low risk for metastasizing and spreading to other parts of the body. It is typically very slow-progressing and is usually diagnosed and treated in very early stages. If left untreated, basal cell carcinomas can be locally destructive to the tissues where it grows, and it can invade deeper structures such as nerves, cartilage, and even bone. In most cases, basal cell carcinoma develops on the face, ears, neck, head, shoulders, hands, and other areas that receive frequent sun exposure. The tumors may look like raised bumps on the skin that are usually smooth and pearly/shiny in appearance. Blood vessels can sometimes be seen within the lesions, and in some cases, a wound may form and bleed easily.

Keeping Cancer In Check

Chronic exposure to the sun or intermittent sunburns can lead to skin cancer. Skin cancer risk doubles with five or more sunburns in a lifetime, but just one bad sunburn can double the risk of melanoma. While skin cancer is uncommon in African Americans, Latinos and Asians, it can also be more deadly because they are often diagnosed later in the course of the disease.

Its important to examine your skin regularly. You should report any changes in an existing mole or any new moles to your physician. People with fair complexions have the highest risk of developing skin cancer, but everyone should avoid the sun and practice safety measures to protect their skin.

The American Cancer Society recommends the Slip, Slop, Slap and Wrap policy. When you go out in the sun, slip on a shirt, slop on sunscreen, slap on a hat and wrap on sunglasses to protect your eyes and the sensitive skin around them.

Exposure to the UV rays of tanning lamps is not safe. Tanning lamps give out UV rays, which can cause long-term skin damage and can contribute to skin cancer. Tanning bed use has been linked with an increased risk of melanoma, especially for people under 30. Most doctors and health organizations recommend not using tanning beds and sun lamps.

Papillary Renal Cell Carcinoma

Sunburn &  Skin Cancer: What You Should Know

Papillary RCC is the second most common form of kidney cancer and makes up about 15% of all cases. Papillary RCC is a non-clear cell renal carcinoma which is different from the more common clear cell type. There are two main types of papillary RCC: type 1 and type 2. Type 1 tumors tend to be slower growing, and type 2 tumors tend to be faster growing and are more likely to spread. Papillary RCC can be The passing of genetic information from parent to child through parental genes.hereditaryor non-hereditary.

What Are The Different Types Of Cancer And Their Causes

Cancer is a disease that starts within our cells. Our bodies are made up of millions of cells, and they group together in order to form tissues and muscles, such as bones and muscles. There is a common misconception that cancer is just one disease this isnt the case.

But, how many types of cancer are there?

There are more than 100 types of cancer that are characterized by abnormal cell growth.? There are numerous different causes, ranging from chemicals to viruses to radiation. Often times, an individual has varying degrees of control over the exposure to cancer-causing agents.

Below, we will take a closer look at the first four commonly recognized types of cancer and their causes:
