Types of skin cancer


skin cancer occurs when the abnormal cells in the epidermis , the outermost layer of the skin, grow to speed control.These abnormal cells are usually caused by exposure to the sun and lead to tumors on the skin.There are several different types of skin cancer, and they, as a rule, can be grouped into four categories: basal cell carcinoma , kvczinoma cells , and carcinoma Merkel cells.

Evaluation of the skin cancer base, which one of the five Americans will develop skin cancer in 70. Each type has its own signs , Symptoms and risk factors.Cell carcinomas and basal planes are not melanoma, and tend to be less aggressive than melanoma cancer. Melanoma and Merkel cell carcinoma are the forms of less common and severe skin cancer.Most of the skin forms of cancer are very suitable, especially when they were called early.

Basil cell carcinoma

cell carcinoma Basals (BCC) is the most common type of cancer.The skin and the most common of all cancer associated hundreds with approximately 4 million diagnoses each year. / P>

This is due when the abnormal basal cells in the epidermis increase.Basal cells are one of the three types of skin cells, and when they are damaged by the sun’s rays or tanning, they can grow too fast.

Signs of the basal cell of the carcinoma

Basal cell carcinoma most often look like a small open wound.It can be red or pink, honestly, skin and brown in humans. You can imagine as a red patch or a lifting to the skin. BCC often has an elevated or rolled border around the wound and can cause bleeding or king.This can be represented in different ways in each person.

BCC is generally found on the body sites exposed to exposure to the sun, such as a face, ears, neck, heads and shoulders and shoulders. If you experienced an open pain that is not healthy or a red leather patch that will not leave the best way to move. LABCC may also look like a brilliant, pearl growth or scar with uncertain borders.The area can be itching, being sick or not having symptoms at all.

Who is at risk?

The main cause of BCC is exposed to ultraviolet rays of solar beds and dwarfs.It may be a higher risk of being diagnosed BCC,If you:

  • there is the story of other types of skin cancer
  • have a sun tanning story
  • over 50 years old
  • right skin
  • man
  • there is a history of chronic skin infections


The Basal cell carcinoma grows slowly, so it is very appropriate. When it was early, the procedures are effective and generally leave the minimum scars, if any.Growth can be eliminated by surgery, radiation and / or drugs. Most of them are ambulatory procedures and require only local numbness.

Surgical options include electrosurgery, Hohs Hooistery , cryosurgery, laser surgery and excipial surgery with a scalpel. Radiation can be effective when a tumor is destroyed without the need for Cut or drug.The actual chemotherapy creams can be applied directly to growth and have healing coefficients by 80-90%, when used early.

The longer the tumor of the skin grows, the more difficult it should be treated.If it is not processed, the BCC can grow in other tissues. And damage the skin, muscles and bones. The longer BCC grows, the greater the probability of recurrence after it is treated.The Advanced BCC may require oral chemotherapy, as well as surgery and radiation.

If you have a History of BCC, your health care provider will inform you about self-taught verification, especially in areas often exposed to the sun.You can protect BCC by taking solar protection seriously with a limited impact, frequent sunscreen and wear a wide hat, lightweight clothing to cover the skin and sunglasses.

Flake carcinoma

Flatllic carcinoma (SCC) is the second most common type of skin cancer after basal cell carcinoma and it is done to control the growth of the Planocells In the epidermis. Sport cells are flat cells in the form of surface skin. About 1 million Americans are diagnosed with CCM each year.

Carcinomas of flat cells with cells with cells most often distributed

as carcinomas of Basal cells, parenting are dragged and generally can be removed completely when over time.However, they are more dangerous than BCC due to their increase in the probability of distribution. SCC most often grows in deeper layers of skin and other tissues in the body than BCC.Although the basal cells of carcinoma generally do not grow in other areas of the body, it can rarely grow in a larger tumor on the skin.

Like BCC,SCC is most frequently found in areas with frequent influence of the sun, such as face, ears, neck, heads and hands. Growth can also occur in scars or pains and it seems that it opens reinforcements, red spots, warts or thickened leather.They can also appear in areas not affected by the sun, such as genitals.

The skin around the growth of SCC can show signs of sun damage such as wrinkles and darker pigment. They can bleed or chop.

Who is at risk? .About 90% of non-skin cancer melanomas are caused by sun exposure, and people who tear in the room have a higher risk of flat bell carcinoma development.

your SCC risk is greater,If you:


When capturing early, flat cell carcinoma is curative.Sliced variants of SCC are similar to those of BCC and include surgery, radiation and actual procedures. The small growth that will capture early, can generally be eliminated by surgery and does not require additional procedures.

If it is not treated, SCC can be metastase and grow in other areas of the body. The more time it grows unnoticed, the harder it is to treat, especially if it reaches the lymph nodes. Each year, around 15,000 people die from SCC.Fortunately, about 95% of the bell cells are trapped at an early stage and are curable. To make the SCC as soon as possible, perform the usual skin controls and consult your health care provider if you do not be cured.

Channel cancer

As basal carcinoma carcinoma and flat cell cells are classified as keratinocyte carcinomas, because they start in the cell of The skin negative.The general cells of the skin produce keratin, protein, responsible for building skin, hair and nails. First grow in a deeper basal layer of the skin and eventually travel on a flat level surface.When these cells are damaged by UV rays of the sun or tanning, they can grow and cause skin cancer.


Melanoma is considered the most serious training of skin cancer due to its high probability of distribution.It is developed in melanocytes, skin cells that produce pigment or melanin. These cells are detected in the upper layer of the skins and are responsible for their color. When our skin is damaged by the sun, it makes melanocytes produce more melanin.That is why the skin looks illuminated after the sun; This solar brightness actually causes skin damage.

Estimates of the base of skin cancer, which in 2020, 196060, Americans will be diagnosed with melanoma, and 100 350 of These cases will be invasive, which means that they began to spread.Melanoma is expected to cause 6,850 deaths in the United States by 2020.

There are four types of melanoma:

  • surface scattering melanoma Melanoma more commonly and seems asymmetric,Different skin patch with unequal edges
  • Slow maligna develops more frequently in the elderly,And it seems a leather of slightly high spots
  • Acral lentiginow melanoma is the most common type of melanoma in people of people and, usually,It looks like a black or brown area under the nail or on the soles of the feet
  • Modular melanoma The most aggressive form of melanoma and is generally present in the form of a black shock or Blue on the skin;It can also be red or pink in color

Signs of melanoma

Melanoma growth usually looks likeLunares, which are brown or black. Sometimes they can grow from previously benign. It is assumed that about 20-30% melanomaz grows from existing polka dots, and 70-80% occurs on normal skin and looked.The growth of melanoma is associated with sun exposure, but it can also grow in areas that do not receive a lot of sunlight. The most common site for women is the leg trunk and the body for men.

The best way to detect melanoma is to follow any skin growth, which are new or changing.Seeing with melanoma, remember ABCDES:

  • Asymmetry: ,When the lunar or growth has two halves that do not match
  • boundaries: the border that is delivered or is not defined, it is worth it that your lunar should be appreciated
  • Color: Multiple multiple colorMelanoma sign
  • Diameter: If you notice a mole or growth that more than the size of the peanuts needed to see
  • Evolving: Any new or changing moth should be estimated for melanoma

Who is in danger

Like other types of skin cancer, melanoma is caused by damage to the sun.The ultraviolet rays of the sun Or the sun tan lead to DNA damage in the skin cells.First, your immune system can restore damage, but over time, mutations in DNA cells can cause the development of skin cancer.

Melanoma is more frequent by an intense exposure to the sun, which leaves a significant burn. In fact, your risk of doubles of melanoma, if you have a history of five or more solar burns in your life.

Your melanoma risk is greater if you:

  • there is a history of skin cancer
  • has a unprotected impact on the sun or the tan of the bed
  • there is the story of melanoma in your family
  • systemimmunological weakened for chronic conditions or medications
  • have a lot of polka dots on your body
  • , it is honest skin

melanoma can work on FamiliesIt is assumed that around one in 10 patients with melanoma is a member of the family that has already been diagnosed with condition. If you have a family history and a lot of polka dots, then it is exposed to risk and has what dermatologists are called Mole Mole Melanoma (FAMMM).


While melanoma is more serious than other skin types Cancer, it is still treated and cured when catching early. When applied to other fabrics and body parts, becomes more complex for treatment.

Melanoma treatment options include surgical removal, radiation, chemotherapy, immunotherapy and directed therapy.Early stage melanoma, which did not extend beyond the first layer of the skin, can generally be eliminated surgically, as well as basal cell carcinomas and aircraft carcinomas.Melanomas that are distributed can be processed by immunotherapy , which are medications that stimulate the immune system to destroy cancer cells.This treatment option is usually more efficient and leads to a smaller number of side effects than chemotherapy. Some methods of therapy can use medications for the cellular attack of ELENOMA, acting on the genes themselves.Chemotherapy and radiation can also be used.

Quinquenal survival rate for Americans, melanoma whose melanoma is early, it is 99%.The survival rate falls to 65%, if melanoma has already been extended to lymph nodes and 25%, if it reached another body. Bodies Interestingly, the level of survival for people who have a family history of melanoma is higher than people without a family history.It is believed that this is due to the fact that those who with family history are more pleasant about skin controls and consult their dermatologists for any problem that helps them discover cancer before.

The eyes of melanoma

Melanoma’s eyes, known as ocular melanoma, is the second type of melanoma most common after the skin of melanoma.This is the most common type of primary eye tumor in adults and leads to the fact that in the United States, it leads to approximately 2,000 new cases in the United States. It begins in melanocytes in the eyes, the cells responsible for the color of the eyes.

Those who are with honest skin and easy eyes to face are subject to ocular melanoma risk, and it is not clear if the damage is guilty.Okular melanoma can be diagnosed during an extended eye exam and has several treatment options, such as radiation, surgical intervention and other methods of treatment.

Merkel cell cancer

Merkel cell cancer – Form of rare and aggressive skin cancer.Each year, around 3,000 Americans are diagnosed by Merkel cell cancer, and leads to 700 deaths annually. It is more than 40 times less than melanoma, and most likely it is extended and return after processing.

Merkel Cell meets deeply into the skins layer. They are associated with nerves and features, such as sensory receptors that send messages about touching and feeling. brain.

Signs of cell cancer Merkel

Merkel cell cancer growth usually resembles blows or solid ulcers and painless. They are in open solar areas of the body, especially head, neck and century.Growth looks like Pearl Acne, similar to packages and can be difficult to recognize. They can be pink, red or purple. It is growing widely, so they have to die from three to five times that melanoma.

Useful to detect the Merkel points cancer cell -Using the AEIU tool:

  • Asymptomatic: Most injuries are painful or soft Touch
  • Extension: Cancer cancer cancer cancer expands and constructs
  • immunokompomised: Competitive immune system, at greater risk
  • , ,More often happens in people over 50 years old / li>
  • UV leather: The defeats are more likely to be present on the Solar Giring Skin (but not always)

  • ,What is at risk?

    Merkel cell cancer can grow in bodily areas that do not receive sunlight, as well as those who often obtain exposure to the sun.Unlike other forms of skin cancer, Merkel cell cancer is associated with a virus called Merkel Polyomavirus.It is not clear how much the virus raises the risk of cancer cancer from Merkel, because the virus is very common, while Merkel’s cancer is quite rare.

    your risk for the increase of cancer merkel cancersi you:

    • has the history of skin cancer
    • have an exposure without protection in the sun
    • there is a weakened immune system
    • leather
    • over 50years
    • man


    CancerosMerkel cells is dangerous, but try , when I trapped it early.Communication rarely, the base of skin cancer recommends finding a medical provider or an academic medical center with a specialized examination in this type of cancer. It will depend on how long cancer has advanced, but generally includes a combination of radiation, immunotherapy and chemotherapy.

    Types rare skin cancer

    Basal cell carcinoma, flat stitch carcinoma, melanoma and cell cancer Merkel make up the overwhelming majority of all cases of skin cancer.However, there are several other types of rare skin cancer:

    • skin t-Cell lymphoma can affect skin, blood, lymph components and internal organs and gifts in a dry form,ZYY Red Rash / Li>
    • Dermatofibrosarcoma protuberans (DFSP) causes an in-depth tumor Leather layers and start as a solid skin patch that rises with time.Tumors have a high rate of repetition or return after processing
    • Kaposi Sarcoma – Rare cancer caused by infection with human herpes virus-8 (HHV-8).This causes an abnormal growth of the fabric under the skin and seems red and purple lesions.Those with a committed immune system, such as people who are HIV positive, are more exposed to risk
    • Silent carcinoma Rare and aggressive cancer,that generally affects the skin over the eyelids or around the century.It is a small, round and painless tumor in the upper or lower eyelid / Li>
    • Dumment Skin Tumors Very rare tumors that grow in thick glands or hair follicles.They are often erroneous as benign growth, and they almost always require a pathologist to diagnose
    • Sarcomas> are cancerous growth that can develop in deep skin layers,as well as coarse bodies, muscles, muscles, nerves and blood vessels

    Greater skin cancer types

    Some predisposed growth,Often related to the effects of the sun can result in skin cancer with time. However, if they are recognized and eliminated early, it can avoid cancer diagnosis.This growth includes:

    • KERATOSIS AKTINICA: Around 40-60% of the cancer cells of cases began as keratosis Aktinica .Anywhere, between 2 and 10% of this growth will be developed in SCC, sometimes in just a couple of years.Actinic Haleit -This type of actinic keratosis, which appears in the lower part of the lip and is exposed to raising the risk of development in skin cancer
    • Bowenz disease: is early,The non-invasive form of SCC has a high risk of skin cancer, if not addressed. It represents as eczema, like a squamous patch and is usually red or brown.This growth was associated with the impact of the sun, radiation, exposure of carcinogen, genetics and injury
    • leucoplakia: these white spots on the lips,Language and gums can be caused by alcohol and tobacco consumption and can become a plane carcinoma.Cancer sites on the lips can be caused by solar damage
    • Keratoacanthoma : This dome The growth is usually found on the open skin of the sun and is generally growing rapidly,Then it slows down. Many are compressed and leaving themselves, but if they continue to grow, this tumor can become a plane carcinoma. Usually,

    are surgically eliminated
