What Happens If Merkel Cell Carcinoma Is Left Untreated

Survey Shows Most People Don’t Know About Common Type Of Skin Cancer

Merkel cell carcinoma is a rare but aggressive and potentially fatal form of skin cancer. It typically affects people above the age of 50 and those who have weakened immune systems. In most cases, Merkel cell carcinoma begins as a skin-toned growth that may bleed easily. The bumps or nodules may also have blue, purple, or red coloring. Because the Merkle cells are near nerve endings, this form of cancer has numerous health risks, and if left untreated, Merkle cell cancer may spread to the brain, lungs, or bones, becoming fatal.

How Does Skin Cancer Become A Life

You may wonder how cancer on the surface of your skin becomes a life-threatening cancer. It seems logical to think you could just scrape off the skin with the cancer cells or even remove the cancerous skin lesion with a minor skin surgery and thats all that would be needed. These techniques are successfully used if cancer is caught early.

But if skin cancer isnt caught early, something thats just on my skin can grow and spread beyond the immediate area. Cancer cells break away and travel through the bloodstream or lymph system. The cancer cells settle in other areas of your body and begin to grow and develop into new tumors. This travel and spread is called metastasis.

The type of cancer cell where cancer first started called primary cancer determines the type of cancer. For example, if malignant melanoma metastasized to the lungs, the cancer would still be called malignant melanoma. This is how that superficial skin cancer can turn into life-threatening cancer.

Risk Factors For Cancers

Tobacco use, alcohol use, unhealthy diet, physical inactivity and air pollution are risk factors for cancer .

Some chronic infections are risk factors for cancer this is a particular issue in low- and middle-income countries. Approximately 13% of cancers diagnosed in 2018 globally were attributed to carcinogenic infections, including Helicobacter pylori, human papillomavirus , hepatitis B virus, hepatitis C virus, and Epstein-Barr virus .

Hepatitis B and C viruses and some types of HPV increase the risk for liver and cervical cancer, respectively. Infection with HIV substantially increases the risk of cancers such as cervical cancer.

What Are The Risk Factors For Skin Cancer

The most common risk factors for skin cancer are as follows.

  • Ultraviolet light exposure, either from the sun or from tanning beds. Fair-skinned individuals, with hazel or blue eyes, and people with blond or red hair are particularly vulnerable. The problem is worse in areas of high elevation or near the equator where sunlight exposure is more intense.
  • A chronically suppressed immune system from underlying diseases such as HIV/AIDS infection or cancer, or from some medications such as prednisone or chemotherapy
  • Exposure to ionizing radiation or chemicals known to predispose to cancer such as arsenic
  • Certain types of sexually acquired wart virus infections
  • People who have a history of one skin cancer have a 20% chance of developing second skin cancer in the next two years.
  • Elderly patients have more skin cancers.

    Most basal cell carcinomas have few if any symptoms. Squamous cell carcinomas may be painful. Both forms of skin cancer may appear as a sore that bleeds, oozes, crusts, or otherwise will not heal. They begin as a slowly growing bump on the skin that may bleed after minor trauma. Both kinds of skin cancers may have raised edges and central ulceration.

    Signs and symptoms of basal cell carcinomas include:

    Signs and symptoms of squamous cell carcinomas include:

    • Persistent, scaly red patches with irregular borders that may bleed easily
    • Open sore that does not go away for weeks
    • A raised growth with a rough surface that is indented in the middle
    • A wart-like growth

      Types Of Vulvar Cancer

      There are several main forms of this disease.

      Squamous cell carcinoma. This is the most common type. It starts in your skin cells. It might be linked to the human papillomavirus , especially in younger women. A subtype called verrucous carcinoma grows slowly and can look like a wart.

      Adenocarcinoma.This type usually starts in cells in the Bartholins glands just inside the opening of your vagina. This is also called Bartholin gland cancer. It can look like a cyst. It also can form in sweat glands in the skin of your vulva or in the top layer of vulvar skin, which is called Pagets disease.

      Melanoma.This type forms in cells that make pigment, or skin color. Youre more likely to get it on skin thats exposed to the sun, but it sometimes forms on your vulva.

      Sarcoma. This starts in bone, muscle, or connective tissue cells. It can happen at any age, including in childhood.

      Basal cell carcinoma.This is the most common type of skin cancer. It usually appears on skin thats exposed to the sun, rarely on the vulva.

      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 Is Vulvar Cancer

      Vulvar cancer is when cancerous cells grow out of control on or in the vulva, the outer part of a womans genitals. Its different from vaginal cancer, which starts inside the vagina.

      A womans vulva includes:

      • The opening of thevagina. This is the tubelike channel that leads out from their uterus.
      • The labia. These are two sets of skin folds that look like lips. The labia majora are the fleshy set on the outside. The labia minora are thinner and set inside them.
      • The clitoris. This is a sensitive knob of tissue under a hood of skin where the labia minora meet.
      • The mons pubis. This is the soft mound in front of their pubic bones that becomes covered with hair in puberty.
      • The perineum. This is the patch of skin between their vulva and anus.

      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 Is Skin Type

      There are six types of skin, ranging from very fair to very dark , according to the scientific classification known as Fitzpatrick skin typing. Developed in 1975 by a Harvard Medical School physician named Thomas Fitzpatrick, MD, the system classifies skin type according to the amount of skin pigment you have and your skins reaction to sun exposure. Determining your skin type can help predict your overall risk for sun damage and skin cancer.

      Treatment For Skin Cancer

      If you are diagnosed with skin cancer, you may have multiple options for treatment. Based on the specifics of your case, your doctor will recommend your best course of action. The suggested methods for fighting the cancer may include:

      • Cryotherapy. In cryotherapy, a doctor freezes and kills precancerous or cancerous skin cells using liquid nitrogen. This technique is most often used to treat minor basal or squamous carcinomas or precancerous skin conditions.

      • Surgery. Different types of skin cancer may be removed by surgery. Surgery can be excisional – simply cutting out a cancerous area and the skin surrounding it – or may involve meticulous removal of layers of skin.

      • Radiation therapy. In radiation therapy, energy beams are used to kill cancerous cells. Radiation therapy may help finish off a cancer that was not fully removed by surgery, and can also be instrumental in cases that dont allow for surgery.

      • Chemotherapy. This type of therapy uses drugs to kill cancer cells. To treat some cases of skin cancer, chemotherapy may be applied locally through topical creams or lotions. It may also be administered by IV to target multiple body parts at once.

      • Immunotherapy. Immunotherapy, also called biological therapy, involves boosting the immune system to fight cancer cells. With the help of strengthening medicines, the immune system may be better prepared to kill cancerous cells.

      What Are The Ten Most Common Cancers

      The most common type of cancer women and men both can have is basal or squamous cell skin cancer. These tend not to be fatal, though some percentage of people with a basal or squamous cell cancer will at a later point develop melanomas. In considering how common a cancer is, the Centers for Disease Control leaves out the above two cancers.

      The CDC addresses common cancer by looking at incidence rates. There are separate lists for men and women, since women and men have separate body parts. For example, a woman doesn’t have a prostate and a man doesn’t have a uterus or cervix. Other statistics in determining common cancers include race and age, as well as region. These factors are of value when evaluating risk for cancer. Behavior must also be taken into account since certain high risk behaviors like alcoholism and smoking increase ones risk for certain forms of cancer, particularly cancer of the lungs and liver.

      The statistics listed here are the total statistics for common cancers. This means that race, behavior and location are not taken into account. Gender is taken into account for the above-mentioned reasons. These statistics do not include basal or squamous cell cancer.

      How Is Skin Cancer Treated

      Skin Cancer Types

      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.

      Can You Prevent Skin Cancer

      According to Dr. Dorsey, Skin cancer is an extremely serious condition, but with proactive care, most cases can be avoided altogether. In fact, taking a few small steps to limit sun damage and conducting regular skin self-exams is all you need to do to keep your skin healthy. Because sun exposure is the main underlying cause of skin cancer, sun protection is essential to prevent this condition. Patients need to apply sunscreen every day and reapply at least every two hours during prolonged sun exposure. Whenever possible, limit or avoid time spent outdoors during peak sun hours between 10 am and 4 pm. If patients need to be outdoors during these times, its important to wear protective coverings, seek shade, and reapply sunscreen frequently.

      In addition to daily sun protection steps, patients also need to perform self-exams at least every month. Early detection is key to providing effective skin cancer treatment, so regular self-exams are an essential part of keeping people healthy. Your Board Certified Dermatologist can walk you through a self-exam when you visit the office, but the basic process involves carefully examining your skin, from the top of your head to the bottoms of your feet , and noting any spots, lesions, bumps, discoloration, or other skin changes or irregularities. When you know where marks are on your skin, youll be more likely to notice if they are growing or changing in ways that are concerning or that indicate skin cancer.

      The Most Common Type Of Skin Cancer

      Basal cell carcinoma is the most common type of skin cancer and it typically looks like a pearly or waxy bump, a flesh-colored growth, or a bleeding sore.

      These most frequently appear on fair-skinned people after years of frequent exposure to the sun. Theyre most commonly found on sun-exposed areas like the head, neck or arms.

      Basal cell carcinoma accounts for more than 80 percent of skin cancer cases.

      If left untreated, basal cell carcinoma can penetrate nerves and bones, causing damage and disfigurement.

      Types of Skin Cancers

      Your skin type is a major factor in your risk for skin cancer, including melanoma. And while its true that people with fair skin tones are more at risk for sunburn, sun damage and skin cancer, UV exposure can raise skin cancer risk even if you tan and dont burn. Thats why it makes sense to know the skin youre in.

      Why Does Skin Cancer Occur In More Non

      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.

      A few other rare skin cancers that might happen on the face:

      • Lymphoma of the skin is an uncommon type of white blood cell cancer.
      • Kaposi’s sarcoma is cancer caused by a herpes virus in immunosuppressed patients that causes skin lesions on the face. They look like painless purplish spots.

      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.
