Which Is Worse Squamous Or Basal Cell Carcinoma

Recurrent Basal Cell Carcinoma

How Dangerous are Basal Cell Carcinoma and Squamous 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

What Is Squamous Cell Carcinoma

Squamous cell carcinoma is second only to basal cell carcinoma in incidence, but is a more serious cancer of the skin. It primarily occurs when there are changes in the skin√Ęs cells. Risk factors is also frequent exposure to ultraviolet light and direct sunlight. This cancer is commonly seen in individuals 50 years and older.

How Widespread Is Bcc

Basal cell carcinoma is quite common, and the number of reported cases in the U.S. has steadily increased.

  • An estimated 3.6 million Americans are diagnosed with BCC each year.
  • More than one out of every three new cancers are skin cancers, and the vast majority are BCCs.
  • The diagnosis and treatment of nonmelanoma skin cancers, including BCC and squamous cell carcinoma , increased up to 77 percent between 1994 and 2014.

What Are The Differences Between Basal Cell Versus Squamous Cell Carcinoma

Basal cell carcinoma usually appears as a pink and waxy smooth papule that slowly enlarges and has the tendency to become ulcerated. It frequently comes out in several areas such as the head, face, neck, hands and arms. Management of basal cell carcinoma often involves excision, electrodessication and curettage, and Mohs microsurgery. Cryotherapy may likewise be used but it is often the second option for treatment, while radiation therapy is not advisable anymore. The cancer grows slowly, invades locally and seldom metastasize. Early identification allows treatment of small tumors and prevention of widespread destruction of the nearby tissues.

On the other hand, squamous cell carcinoma has the tendency to spread to the other parts of the body, particularly to the lymph nodes. Frequency of exposure to ultraviolet light seems to be more significant to the pathogenesis of squamous cell carcinoma as compared to basal cell carcinoma. Most squamous cell carcinomas often develop in the sun-exposed areas but it can also occur anywhere including the mucous membranes. Their lesions appear as hyperkeratotic, erythematous and crusted nodule that may be loose on the surface and oftentimes tender to the touch. Treatment is almost similar to that of basal cell carcinoma. Anti-cancer topical creams are usually administered. Surgery and Mohs microsurgery are also performed depending on the size of the skin growth.

What Are The Stages Of Squamous Cell Carcinoma

Another example of basal cell carcinoma with squamous ...

Squamous cell carcinoma is classified into the following stages, which are partly based on how far the cancer has spread throughout the body:

  • Stage 0 Squamous cell carcinoma develops in the squamous cells, which are located in the epidermis . During Stage 0, the cancer hasnt spread beyond the epidermis.
  • Stage 1 When squamous cell carcinoma progresses to Stage 1, it means that the cancer has spread deeper into the skin, but not into any lymph nodes or healthy tissues.
  • Stage 2 A Stage 2 classification means that, in addition to progressing deeper into the skin, the cancer also displays at least one high-risk feature. This might include metastasizing to the lower skin layers or the nerves. However, at this stage, the cancer still hasnt spread to lymph nodes or healthy tissues.
  • Stage 3 Once squamous cell carcinoma reaches Stage 3, the cancer has spread into lymph nodes but not any other tissues or organs.
  • Stage 4 This is the final stage of squamous cell carcinoma, where the cancer has spread to at least one distant organ, whether that be the brain, the lungs or a separate area of skin.

If you think you might have squamous cell carcinoma, its important to seek prompt medical attention to minimize the risk of cancer spread.

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.

What Happens If Basal Cell Carcinoma Is Left Untreated

If left untreated, basal cell carcinomas can become quite large, cause disfigurement, and in rare cases, spread to other parts of the body and cause death. Your skin covers your body and protects it from the environment. Your skin is composed of three major layers, the epidermis, dermis, and subcutaneous tissue.

How Dangerous Is Bcc

While BCCs rarely spread beyond the original tumor site, if allowed to grow, these lesions can be disfiguring and dangerous. Untreated BCCs can become locally invasive, grow wide and deep into the skin and destroy skin, tissue and bone. The longer you wait to have a BCC treated, the more likely it is to recur, sometimes repeatedly.

There are some highly unusual, aggressive cases when BCC spreads to other parts of the body. In even rarer instances, this type of BCC can become life-threatening.

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.

How Is Skin Cancer Of The Head And Neck Diagnosed

Diagnosis is made by clinical exam and a biopsy. Basal cell and squamous cell cancers are staged by size and extent of growth. Basal cell cancers rarely metastasize to lymph nodes, but they can grow quite large and invade local structures. Squamous cell cancers have a much higher incidence of lymph node involvement in the neck and parotid gland and can spread along nerves.

Melanoma is staged, based not on size but on how deeply it invades the skin layers. Therefore, a superficial or shave biopsy will not provide accurate staging information used to guide treatment. Melanomas can have a very unpredictable course and may spread to distant organs. Melanomas with intermediate thickness often require sentinel node biopsy, a surgical procedure performed by a head and neck surgeon, to determine if microscopic spreading to lymph nodes has occurred.

What Is A Melanocyte

Melanocytes are skin cells found in the upper layer of skin. They produce a pigment known as melanin, which gives skin its color. There are two types of melanin: eumelanin and pheomelanin. When skin is exposed to ultraviolet radiation from the sun or tanning beds, it causes skin damage that triggers the melanocytes to produce more melanin, but only the eumelanin pigment attempts to protect the skin by causing the skin to darken or tan. Melanoma occurs when DNA damage from burning or tanning due to UV radiation triggers changes in the melanocytes, resulting in uncontrolled cellular growth.

About Melanin

Naturally darker-skinned people have more eumelanin and naturally fair-skinned people have more pheomelanin. While eumelanin has the ability to protect the skin from sun damage, pheomelanin does not. Thats why people with darker skin are at lower risk for developing melanoma than fair-skinned people who, due to lack of eumelanin, are more susceptible to sun damage, burning and skin cancer.

Squamous Or Basal Cell Cancer: Which One is Worse?

Basal cell carcinoma and squamous cell carcinoma are the two most common types of skin cancers. According to the American Cancer Society, over 5 million cases of basal cell and squamous cell cancers are diagnosed every year. Though, basal cell carcinoma occurs more often, taking credit for about 80% of these cases. Other than the disparities in occurrence, what is the difference between basal cell and squamous cell carcinomas? You may also be wondering is squamous cell worse than basal cell, or vice versa. Here is some insight.

What Are The Symptoms Of Squamous Cell Carcinoma

Squamous cell carcinomas are usually raised growths, ranging from the size of a pea to the size of a chestnut. They may appear as scaly red patches, open sores or protruding growths with a dented center, or they may look like a wart. Most are found in areas of the body that are frequently exposed to the sun, such as the ears, lips, face, balding scalp, neck, hands, arms, and legs. Less commonly, they may appear on mucous membranes and genitals. Regardless of what form the bumps take, they do not heal or go away on their own.

How Dangerous Is Scc

While the majority of SCCs can be easily and successfully treated, if allowed to grow, these lesions can become disfiguring, dangerous and even deadly. Untreated SCCs can become invasive, grow into deeper layers of skin and spread to other parts of the body.

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 Meant By Squamous Cell Carcinoma

Basal and Squamous Cell Skin Cancers: Treatment including Mohs Surgery Video – Brigham and Womens

Squamous cell cancer , also known as squamous cell carcinoma, is a type of skin cancer that begins in the squamous cells. Squamous cells are the thin, flat cells that make up the epidermis, or the outermost layer of the skin. People with SCC often develop scaly, red patches, open sores, or warts on their skin.

Consequently, how serious is a squamous cell carcinoma?

Squamous cell carcinoma of the skin is usually not life-threatening, though it can be aggressive. Untreated, squamous cell carcinoma of the skin can grow large or spread to other parts of your body, causing serious complications.

Likewise, what does a squamous cell carcinoma look like? Squamous cell carcinomas may appear as flat reddish or brownish patches in the skin, often with a rough, scaly, or crusted surface. They tend to grow slowly and usually occur on sun-exposed areas of the body, such as the face, ears, neck, lips, and backs of the hands. Normal moles also develop from these skin cells.

Similarly, how does squamous cell carcinoma start?

Squamous cell carcinoma usually starts out as a small, red, painless lump or patch of skin that slowly grows and may ulcerate. It usually occurs on areas of skin that have been repeatedly exposed to strong sunlight, such as the head, ears, and hands.

Where Do Skin Cancers Start

Most skin cancers start in the top layer of skin, called the epidermis. There are 3 main types of cells in this layer:

  • Squamous cells: These are flat cells in the upper part of the epidermis, which are constantly shed as new ones form. When these cells grow out of control, they can develop into squamous cell skin cancer .
  • Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skins surface. As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells. Skin cancers that start in the basal cell layer are called basal cell skin cancers or basal cell carcinomas.
  • Melanocytes: These cells make the brown pigment called melanin, which gives the skin its tan or brown color. Melanin acts as the bodys natural sunscreen, protecting the deeper layers of the skin from some of the harmful effects of the sun. Melanoma skin cancer starts in these cells.

The epidermis is separated from the deeper layers of skin by the basement membrane. When a skin cancer becomes more advanced, it generally grows through this barrier and into the deeper layers.

What Are Basal And Squamous Cell Skin Cancers

Basal and squamous cell skin cancers are the most common types of skin cancer. They start in the top layer of skin , and are often related to sun exposure.

Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer cells. To learn more about cancer and how it starts and spreads, see What Is Cancer?

What Are The Treatment Options For Melanoma

Surgery performed to remove the melanoma while leaving as much nearby skin intact as possible. The surgeon may also remove one or more nearby lymph nodes to look for signs that the cancer has spread.

Targeted therapy uses drugs directed at specific abnormal proteins in cancer cells. Patients whose melanoma carries a mutation in the BRAF gene may be treated with drugs that target the altered BRAF protein or the associated MEK proteins. Three drug combinations have been FDA-approved for metastatic and high-risk melanoma with a BRAF mutation: dabrafenib and trametinib encorafenib and binimetinib and vemurafenib and cobimetinib

Immunotherapy uses the bodys immune system to fight cancer cells. Dana-Farber scientists have led clinical trials of the drug ipilimumab, one of a class of immunotherapy drugs that are helping some patients with advanced melanoma survive 10 years or longer. In other Dana-Farber-led trials, the immunotherapy agent nivolumab achieved three-year survival rates of more than 40% in patients with metastatic melanoma. Dana-Farber investigators have also found that initially treating advanced melanoma patients a combination of nivolumab and ipilimumab results in a much higher response rate than treatment with ipilimumab alone. A range of other clinical trials testing various immunotherapies is also under way for patients with advanced melanoma.

Medical Treatment For Skin Cancer

SQUAMOUS OR BASAL CELL CANCER: WHICH ONE IS WORSE? by ...

Surgical removal is the mainstay of skin cancer treatment for both basal cell and squamous cell carcinomas. For more information, see Surgery.People who cannot undergo surgery may be treated by external radiation therapy. Radiation therapy is the use of a small beam of radiation targeted at the skin lesion. The radiation kills the abnormal cells and destroys the lesion. Radiation therapy can cause irritation or burning of the surrounding normal skin. It can also cause fatigue. These side effects are temporary. In addition, topical chemotherapy creams have been FDA approved for the treatment of certain low-risk nonmelanoma skin cancers. Patients with advanced or many basal cell carcinomas are sometimes prescribed oral pills to block the growth of these cancers. Side effects include muscle spasms, hair loss, taste changes, weight loss and fatigue.

In advanced cases of melanoma, immune therapies, vaccines, or chemotherapy may be used. These treatments are typically offered as clinical trials. Clinical trials are studies of new therapies to see if they can be tolerated and work better than existing therapies.
