Where Within The Skin Layers Does Skin Cancer Develop
Where skin cancer develops specifically, in which skin cells is tied to the types and names of skin cancers.
Most skin cancers begin in the epidermis, your skins top layer. The epidermis contains three main cell types:
- Squamous cells: These are flat cells in the outer part of the epidermis. They constantly shed as new cells form. The skin cancer that can form in these cells is called squamous cell carcinoma.
- Basal cells: These cells lie beneath the squamous cells. They divide, multiply and eventually get flatter and move up in the epidermis to become new squamous cells, replacing the dead squamous cells that have sloughed off. Skin cancer that begins in basal cells is called basal cell carcinoma.
- Melanocytes: These cells make melanin, the brown pigment that gives skin its color and protects your skin against some of the suns damaging UV rays. Skin cancer that begins in melanocytes is called melanoma.
Prevention Of Basal Cell Carcinoma
Because basal cell carcinoma is often caused by sun exposure, people can help prevent this cancer by doing the following:
Avoiding the sun: For example, seeking shade, minimizing outdoor activities between 10 AM and 4 PM , and avoiding sunbathing and the use of tanning beds
Wearing protective clothing: For example, long-sleeved shirts, pants, and broad-brimmed hats
Using sunscreen: At least sun protection factor 30 with UVA and UVB protection used as directed and reapplied every 2 hours and after swimming or sweating but not used to prolong sun exposure
In addition, any skin change that lasts for more than a few weeks should be evaluated by a doctor.
Is Nonmelanoma Skin Cancer A Disability & Can You Die From It
People can die from Nonmelanoma skin cancer if timely treatment is not carried out and the disease is left untreated. When not treated cancer can spread to surrounding tissues and other areas/parts of the body. It is not disabling if diagnosed early and treatment is started. Treatment side effects may cause some fatigue and tiredness. If surgery is done, you may have to take rest for a day or days depending on the anesthesia used.
The nonmelanoma skin cancer is primarily of two types, basal cell carcinoma, and squamous cell carcinoma. Both two forms have excellent long-term survival chances. If you are suffering from basal cell carcinoma, the 5-year survival rate is 100% and that for squamous cell carcinoma is 95%. Early detection and the start of treatment are essential for both cases. To differentiate them definitively, a biopsy is sometimes necessary. Nonmelanoma skin cancers usually grow slowly.
The majority of skin cancer cases result from long-term, prolonged exposure to ultraviolet radiation from the sun or tanning beds or lamps. Thus, this type of cancer usually sits on parts of the body exposed to UV rays such as the face, neck, and back of the hands.

What Is The Outlook For People With Skin Cancer
Nearly all skin cancers can be cured if they are treated before they have a chance to spread. The earlier skin cancer is found and removed, the better your chance for a full recovery. Ninety percent of those with basal cell skin cancer are cured. It is important to continue following up with a dermatologist to make sure cancer does not return. If something seems wrong, call your doctor right away.
Most skin cancer deaths are from melanoma. If you are diagnosed with melanoma:
- The five-year survival rate if its detected before it spreads to the lymph nodes is 99%.
- The five-year survival rate if it has spread to nearby lymph nodes is 66%.
- The five-year survival rate if it has spread to distant lymph nodes and other organs is 27%.
When Should I See My Doctor
If you have had one BCC, you have a 50% chance of developing another one, so it is important to check your skin regularly.
Most people find BCCs by checking their own skin and looking for changes. See a doctor if you find:
- a spot that is different from other spots on your skin
- a spot that has changed size, shape, colour or texture
- a sore that doesnt heal
- a sore that is itchy or bleeds

What Causes Basal Cell Carcinoma
BCC develops from exposure to damaging ultraviolet sunlight and tanning beds. This cancer starts in the basal cell layer of the skin and grows very slowly. It develops mainly on the areas exposed to the sun, such as the:
- Head and face
Risk factors for basal cell carcinoma include:
- Exposure to UV radiation

Basal Cell And Squamous Cell Carcinomas
Basal cell carcinoma and squamous cell carcinoma are the most common types of cancer, but also the least likely to spread. In particular, BCCs rarely spread beyond the initial tumor site. However, left untreated, BCCs can grow deeper into the skin and damage surrounding skin, tissue, and bone. Occasionally, a BCC can become aggressive, spreading to other parts of the body and even becoming life threatening. Also, the longer you wait to have your BCC treated, the more likely it is to return after treatment. Like BCCs, SCCs are highly curable when caught and treated early. However, if left to develop without treatment, an SCC can become invasive to skin and tissue beyond the original skin cancer site, causing disfigurement and even death. Over 15,000 Americans die each year from SCCs. And even if untreated carcinomas dont result in death, they can lead to large, open lesions on the skin that can cause discomfort, embarrassment, and infection.

Leaving Basal Cell Carcinoma Untreated
Basal cell carcinoma is a slow growing cancer, but this doesnt mean it can be ignored. This is the least dangerous form of skin cancer and rarely spreads to other internal parts of the body. While death is a rare consequence there is the potential for disfigurement. Over time basal cell carcinoma can expand and cause ulcers and damage the skin and tissues.
Any damage could be permanent and have an impact on the way you look. Depending on how long the basal cell carcinoma has been present, radiotherapy may be required. This is the most common form of skin cancer and is often found on the face. You may notice a small lump which is shiny or pearl like and this is a sign you should get checked. This type of cancer generally does not cause any pain.
What Is A Basal Cell Carcinoma
Basal cell carcinoma is a type of skin cancer that occurs when there is damage to the DNA of basal cells in the top layer, or epidermis, of the skin. They are called basal cells because they are the deepest cells in the epidermis. In normal skin, the basal cells are less than one one-hundredth of an inch deep, but once a cancer has developed, it will spread deeper.

How Do You Treat Skin Cancer On The Nose
The nose is a relatively common spot for skin cancer to develop. Skin cancer often starts on the face because it’s usually the body part that’s exposed to the sun. The two most common types of skin cancer that develop on the nose are basal cell carcinoma and squamous cell carcinoma . While both types of skin cancer should be addressed right away, BCC is usually slow-growing and SCC grows more quickly. Basal cell carcinoma is the most common type of skin cancer ,with about 80% of cases occurring on the face and 25 to 30% on the nose.
The third type of skin cancer, melanoma, is rare and much more serious. It almost always requires excisional surgery to remove it. Fortunately, most forms of skin cancer are very treatable, especially when caught early. Treatment may include surgery, radiation, topical treatments, and more.
Can You Die From Skin Cancer If Youre Diagnosed With Merkel Cell Carcinoma
Merkel cell carcinoma has been compared to melanoma and is often treated like melanoma, but it is different. MCC is a relatively rare form of skin cancer that results in about 2,000 new cases per yearmost of them men over the age of 50. The risk continues to increase with age. Merkel cell carcinoma is fatal in approximately one-third of cases.
MCC is caused by uncontrolled growth of Merkel cells located in the epidermis. The disease is likely to appear as a painless, red or violet-colored lump on the skin that has been overexposed to the sun, especially the head, neck, and arms.
The cells grow rapidly and spread to nearby lymph nodes, then to distant nodes or skin in other parts of the body.
In addition to age and exposure to sunlight, risk factors include a weakened immune system, exposure to artificial sunlight, use of drugs that weaken the immune system, and a history of other types of cancer.
Treatment might require surgery, radiation, and/or chemotherapy. Early detection and treatment is essential to prevent metastasis.

How Serious Is My Cancer
If you have skin cancer, the doctor will want to find out how far it has spread. This is called staging.
Basal and squamous cell skin cancers don’t spread as often as some other types of cancer, so the exact stage might not be too important. Still, your doctor might want to find out the stage of your cancer to help decide what type of treatment is best for you.
The stage describes the growth or spread of the cancer through the skin. It also tells if the cancer has spread to other parts of your body that are close by or farther away.
Your cancer can be stage 0, 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread beyond the skin. Be sure to ask the doctor about the cancer stage and what it means for you.
Other things can also help you and your doctor decide how to treat your cancer, such as:
- Where the cancer is on your body
- How fast the cancer has been growing
- If the cancer is causing symptoms, such as being painful or itchy
- If the cancer is in a place that was already treated with radiation
- If you have a weakened immune system
Diagnosis Of Skin Cancer
It is important to check your skin regularly and check with your doctor if you notice any changes.
In the majority of cases, your GP will examine you, paying attention to any spots that may look suspicious. Your GP may perform a biopsy . In some cases your GP may refer you to a specialist, such as a dermatologist, if necessary.

How Can You Tell If A Spot Is Skin Cancer
Redness or new swelling beyond the border of a mole. Color that spreads from the border of a spot into surrounding skin. Itching, pain, or tenderness in an area that doesnt go away or goes away then comes back. Changes in the surface of a mole: oozing, scaliness, bleeding, or the appearance of a lump or bump.
Skin Cancer Of The Head And Neck Treatment
Many early-stage small basal cell cancers or squamous cell cancers can be removed by Mohs surgery, a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Tumors with nerve involvement, lymph node involvement or of a large size are not suitable for Mohs surgery. They require a multimodality approach to treatment, with formal surgical resection and adjuvant radiation or chemotherapy.
Melanoma is more likely to spread, and aggressive surgical resection with wide margins is required, in addition to radiation and/or chemotherapy.

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.
Prognosis Of Basal Cell Carcinoma
Treatment of basal cell carcinoma is nearly always successful, and the cancer is rarely fatal. However, almost 25% of people with a history of basal cell carcinoma develop a new basal cell cancer within 5 years of the first one. Thus, anyone with one basal cell carcinoma should have a yearly skin examination.

Survival Statistics For Non
Most cancer registries do not collect information about non-melanoma skin cancers. These cancers are difficult to keep track of. The information often doesnt get reported because non-melanoma skin cancer is usually diagnosed and treated easily in a doctors office.
In Canada, a few provinces do collect information on new cases of non-melanoma skin cancer. Canadian statistics for non-melanoma skin cancer, including survival statistics, are based on the information gathered by these provinces.
Survival statistics for non-melanoma skin cancer are general estimates and must be interpreted carefully. Because these statistics are based on the experience of groups of people, they cannot be used to predict a particular persons chances of survival.
There are many different ways to measure and report cancer survival statistics. Your doctor can explain the statistics for non-melanoma skin cancer and what they mean to you.
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.

What Happens If I Dont Have A Basal Cell Carcinoma Treated
As mentioned above, basal cell carcinomas are almost never fatal, but they can be highly disfiguring if left to grow unimpeded. These lesions will grow wider and will penetrate more deeply into the skin, damaging underlying tissue and eventually bone. Removing these growths once they have become so established will involve removing much more surrounding tissue and possibly bone, which can be quite challenging if the growth is on an area such as the face.
Another thing about leaving a basal cell carcinoma untreated is that by doing so you are increasing the odds it will return even if it is removed at this point. Now youll have extra future costs of excision or another removal, along with more tissue loss.
None of this should happen. When basal cell carcinoma is diagnosed early on, removing the lesion is usually quite simple and the success rate is very high. If addressed early, its unlikely another basal cell carcinoma will return to that location, as well.
What Happens When Skin Cancer Goes Untreated
If you notice an abnormality on your skin you may be tempted to ignore it. However, if it is skin cancer you could be putting your health at risk by waiting to get a skin and mole check. There are three main types of skin cancer in Australia with melanoma, basal cell carcinoma and squamous cell carcinoma, and they each have their own set of unique characteristics. The most important thing to remember is that if you delay treatment of skin cancer it could have life threatening consequences:

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 Is Skin Cancer
Cancer can start any place in the body. Skin cancer starts when cells in the skin grow out of control.
Skin cancer cells can sometimes spread to other parts of the body, but this is not common. When cancer cells do this, its called metastasis. To doctors, the cancer cells in the new place look just like the ones from the skin.
Cancer is always named based on the place where it starts. So if skin cancer spreads to another part of the body, its still called skin cancer.
