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.
Main Types Of Skin Cancers
The 4 main types of skin cancer include:
- Sore that does not heal or heals and returns
- Brown or black discolored stripe under a nail
Merkel cell carcinoma
Sebaceous gland cancer
Dark Lines On The Fingernails Or Toenails
The appearance of a dark area under a fingernail or toenail that appears without an obvious injury should always be investigated. Melanoma of the nail bed often presents when a pigmented streak of the nail involves the cuticle . These cancers are most common on the thumb and big toe but may occur on any nail.
While subungual melanomas are uncommon in whites, accounting for only around 1% of melanomas, they are the most common form of melanoma found in dark-skinned individuals.

What Is The Treatment For Skin Cancer
Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy or immunotherapy or both. Because of the complexity of treatment decisions, people with malignant melanoma may benefit from the combined expertise of the dermatologist, a cancer surgeon, and a medical oncologist.

Ultraviolet light exposure, most commonly from sunlight, is overwhelmingly the most frequent cause of skin cancer.
Other important causes of skin cancer include the following:
- Use of tanning booths
- Immunosuppression â This means impairment of the immune system. The immune system protects the body from foreign entities, such as germs or substances that cause an allergic reaction. This suppression may occur as a consequence of some diseases or can be due to medications prescribed to combat conditions such as autoimmune diseases or prevent organ transplant rejection.
- Exposure to unusually high levels of X-rays
- Contact with certain chemicals-arsenic , hydrocarbons in tar, oils, and soot
The following people are at the greatest risk:
A basal cell carcinoma usually looks like a raised, smooth, pearly bump on the sun-exposed skin of the head, neck, or shoulders.
A squamous cell carcinoma is commonly a well-defined, red, scaling, thickened patch on sun-exposed skin.

Basic Information About 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 Cancers On The Face
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.
- Skin adnexal tumors is a rare cancer type that starts in hair follicles or skin glands.
- Sarcomas are tumors of the connective tissuesspecifically the fat, nerves, bone, skin, and muscles 80% of which occur in the face, head, or neck.
- Cutaneous leiomyosarcoma is an uncommon soft-tissue sarcoma that can happen on the face.

Melanoma Skin Cancer Growth Rate
Melanoma skin cancer is the most dangerous and aggressive type of skin cancer, but it is significantly less common than other, non-melanoma types of skin cancer like Squamous cell carcinoma and Basal cell carcinoma. Melanoma skin cancer has a rapid growth rate, which is what makes it so dangerous it can turn life-threatening in just six weeks and poses a high risk of spreading to other parts of the body if left untreated. The early form of squamous cell carcinoma is known as Bowens disease.
What Is A Basal Cell
One of three main types of cells in the top layer of the skin, basal cells shed as new ones form. BCC most often occurs when DNA damage from exposure to ultraviolet radiation from the sun or indoor tanning triggers changes in basal cells in the outermost layer of skin , resulting in uncontrolled growth.

What Are The Treatments For Skin Cancer
Most skin cancers are detected and cured before they spread. Melanoma that has spread to other organs presents the greatest treatment challenge.
Standard treatments for localized basal cell and squamous cell carcinomas are safe and effective and cause few side effects. Small tumors can be surgically excised, removed with skin scraping and electric current cauterization, frozen with liquid nitrogen, or killed with low-dose radiation.
In rare cases where basal cell or squamous cell carcinoma has begun to spread beyond the local skin site, the primary tumors are first removed surgically. Then patients may be treated with radiation, immunotherapy in the form of interferon, and rarely, chemotherapy. However, responses to this therapy are infrequent and short-lived. Rare patients with advanced squamous cell carcinoma respond well to a combination of retinoic acid and interferon . Retinoic acid may inhibit cancer recurrence in patients who have had tumors removed, but there is a lack of evidence to support either of these treatments. Vismodegib may be used to treat the rare cases of locally advanced, or metastatic, basal cell carcinoma and has been shown to shrink these tumors. Sonidegib can be used to treat patients with locally advanced basal cell carcinoma who are not candidates for surgery or radiation. It may also be used if the skin cancer returns after surgery or radiation.
Diagnosis And Staging What It Means For You
How is melanoma diagnosed?
To diagnose melanoma, a dermatologist biopsies the suspicious tissue and sends it to a lab, where a dermatopathologist determines whether cancer cells are present.
After the disease is diagnosed and the type of melanoma is identified, the next step is for your medical team to identify the stage of the disease. This may require additional tests including imaging such as PET scans, CT scans, MRIs and blood tests.
The stage of melanoma is determined by several factors, including how much the cancer has grown, whether the disease has spread and other considerations. Melanoma staging is complex, but crucial. Knowing the stage helps doctors decide how to best treat your disease and predict your chances of recovery.

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.

Who Is At Risk Everyone
Frankly, everyone is at risk of skin cancer but it does affect some skin types more than others. However, the whiter or paler the skin, the more common skin cancer is.
In fact, the number of people with non-pigmented and pigmented skin cancers has been increasing over the past few decades. Globally every year there are between 2 and 3 million non-pigmented skin cancers and 132,000 melanoma skin cancers. The main causes of skin cancer are genetic and ethnicity. Caucasian populations have a higher risk of getting skin cancers than darker-skinned populations.
The sun is a major risk factor, so if you indulge in outdoor activity you will be subject to more sun exposure and increase the risk of getting skin cancer. A sun burn, harms your skin cells DNA and repetitive skin cell damage increases the risk of developing skin cancer.
Despite higher risks for different skin colors, no one is exempt from this disease and we have some great examples to demonstrate that

Causes Of Skin Cancer
Both types of skin cancer occur when mutations develop in the DNA of your skin cells. These mutations cause skin cells to grow uncontrollably and form a mass of cancer cells.
Basal cell skin cancer is caused by ultraviolet rays from the sun or tanning beds. UV rays can damage the DNA inside your skin cells, causing the unusual cell growth. Squamous cell skin cancer is also caused by UV exposure.
Squamous cell skin cancer can also develop after long-term exposure to cancer-causing chemicals. It can develop within a burn scar or ulcer, and may also be caused by some types of human papillomavirus .
The cause of melanoma is unclear. Most moles dont turn into melanomas, and researchers arent sure why some do. Like basal and squamous cell skin cancers, melanoma can be caused by UV rays. But melanomas can develop in parts of your body that arent typically exposed to sunlight.
Your recommended treatment plan will depend on different factors, like the size, location, type, and stage of your skin cancer. After considering these factors, your healthcare team may recommend one or more of the following treatments:

Does Skin Cancer Affect People With Skin Of Color
People of all skin tones can develop skin cancer. If you are a person of color, you may be less likely to get skin cancer because you have more of the brown pigment, melanin, in your skin.
Although less prevalent than in nonwhite people, when skin cancer does develop in people of color, its often found late and has a worse prognosis. If youre Hispanic, the incidence of melanoma has risen by 20% in the past two decades. If youre Black and develop melanoma, your five-year survival rate is 25% lower than it is for white people . Part of the reason may be that it develops in less typical, less sun-exposed areas and its often in late-stage when diagnosed.
Q: What Does Treatment Of Skin Cancer Look Like
Patel: Skin cancers are generally treated by surgical excision to remove the tumor and a surrounding margin of normal skin around the cancer. Occasionally, in advanced cases, treatment beyond surgery may be needed, such as removal of lymph node tissues or radiation therapy. Also, in certain early or superficial skin cancers, topical creams or immune therapies can be utilized. There are also a variety of treatments for prevention of skin cancer.

Where Does Skin Cancer Develop
Skin cancer is most commonly seen in sun-exposed areas of your skin your face , ears, neck, arms, chest, upper back, hands and legs. However, it can also develop in less sun-exposed and more hidden areas of skin, including between your toes, under your fingernails, on the palms of your hands, soles of your feet and in your genital area.
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

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.
