The Risks The Causes What You Can Do
Basal cell carcinoma is caused by damage and subsequent DNA changes to the basal cells in the outermost layer of skin. Exposure to ultraviolet radiation from the sun and indoor tanning is the major cause of BCCs and most skin cancers.
Understanding what causes BCC and the factors that increase your risk of getting it can help you prevent the disease or detect it in its earliest stages, when its easiest to treat.
These factors increase your BCC risk:
How Dangerous Is A Basal Cell Carcinoma
While melanoma rightly deserves the attention it receives as the most dangerous form of skin cancer, basal cell carcinoma isnt something to brush off as harmless. Yes, this most common form of skin cancer rarely causes fatalities, but it can become quite disfiguring.
While basal cell carcinoma lesions rarely spread beyond the original tumor site, they should not be allowed to grow freely. These lesions can grow widely, penetrating deeply into the skin destroying skin, tissue, and bone. Plus, the longer you leave a basal cell carcinoma untreated, the more likely it is to come back. And because it will usually return in the same area, this can create problems removing the lesions without overly disfiguring the patient.
Prognosis For 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.

Squamous Cell Skin Cancer
SCC is generally faster growing than basal cell cancers. About 20 out of every 100 skin cancers are SCCs. They begin in cells called keratinocytes, which are found in the epidermis.
Most SCCs develop on areas of skin exposed to the sun. These areas include parts of the head, neck, and on the back of your hands and forearms. They can also develop on scars, areas of skin that have been burnt in the past, or that have been ulcerated for a long time.
SCCs don’t often spread. If they do, it’s most often to the deeper layers of the skin. They can spread to nearby lymph nodes and other parts of the body, but this is unusual.
What You Can Do
If youve already had a BCC, you are more likely to develop another, especially in the same sun-damaged area or nearby.
A BCC can recur even when it has been carefully removed the first time, because some cancer cells may remain undetectable after surgery and others can form roots that extend beyond whats visible. BCCs on the nose, ears and lips are more likely to recur, usually within the first two years after surgery.
Heres what you can do to detect a recurrence and prevent further skin damage that can lead to cancer:

Causes Of Squamous Cell Carcinoma
The mutations that occur in the skin cell DNA causes skin cancer. Such changes cause abnormal cells to multiply uncontrollably. When this occurs in squamous cells, it gives rise to squamous cell cancer. DNA mutations are generally caused by UV radiation found in the sun, tanning lamps, and beds.
As we read, exposure to UV radiation increases the risk of cancer. Still, it is pretty shocking to know that less exposure to sunlight or tanning lamps also increases the risk of squamous cell carcinoma.
Studies also reveal that people with a weak immune system are likely to develop skin cancer. Radiation therapy also increases the risk of squamous cell carcinoma.
What Is Basal Cell Cancer
- The outer layer is called the epidermis
- The inner layer is called the dermis
- The deep layer of fat is called the hypodermis
The round cells in the lower epidermis are known as basal cells. These cells are constantly dividing to form new cells, which replace squamous cells and push old cells to the surface to die.
Basal cell carcinoma is the most common type of skin cancer, accounting for about 80% of all skin cancer cases.

- Curettage and cautery the skin is numbed with local anaesthetic and the BCC is scraped away and then the skin surface is sealed by heat .
- Cryotherapy freezing the BCC with liquid nitrogen.
- Creams these can be applied to the skin. The two most commonly used are 5-fluorouracil and imiquimod.
- a special cream is applied to the BCC which is taken up by the cells that are then destroyed by exposure to a specific wavelength of light. This treatment is only available in certain dermatology departments .
Surgical excision is the preferred treatment, but the choice of other treatments depends on the site and size of the BCC, the condition of the surrounding skin and number of BCC to be treated as well as the overall state of health of each person to be treated.
What Is The Staging For Basal Cell Skin Cancer
Basal cell carcinomas rarely spread so they are not typically staged. If the tumor is large and it is suspected of spreading to other parts of the body, then staging may be used.
Staging for basal cell carcinomas is similar to the staging for another type of skin cancer called squamous cell carcinoma :
- Stage 0: Cancer involves only the epidermis and has not spread to the dermis .
- Stage I: Cancer is not large and has not spread to the lymph nodes or other organs.
- Stage II: Cancer is large but has not spread to lymph nodes or other organs.
- Stage III: Cancer has spread to tissues beneath the skin such as muscle, bone, or cartilage, and/or to regional lymph nodes but not to other organs.
- Stage IV: Cancer can be any size and has spread to other organs.

When Should I See My Healthcare Provider
Its important to contact a healthcare provider any time you have a skin problem that doesnt resolve on its own. If you develop any new marks on your skin, if you have a mole that gets larger or if you experience any symptoms like pain or itchiness associated with the lump or lesion on your skin, contact a provider.
How Can I Prevent Basal Cell Carcinoma From Recurring
Most basal cell carcinomas can be treated and cured. However, it is possible for these types of cancers to recur or for new skin cancers to appear.
Do the following to reduce the risk of new cancers occurring:
- Keep all follow-up appointments with your GP or skin specialist.
- Regularly check all your skin . If you see anything that is growing, bleeding or in any way changing, go and see your doctor straight away. See skin checks
- Protect your skin from the sun and avoid indoor tanning. This is essential to prevent further damage, which will increase the risk of getting another skin cancer.

How Successful Is Basal Cell Carcinoma Treatment
Mohs micrographic surgery has the best cure rates with basal cell carcinoma, a 99 percent cure rate for carcinomas that are not returning growths. The cure rate when basal cell carcinomas are removed with wide excision can be as high as 98 percent. With curettage and electrodesiccation, the rate is from 91 to 97 percent.
Basal cell carcinoma is not considered life-threatening in almost all cases. It is simply disfiguring.

What Is The Staging For Skin Cancer
There is no specific staging system for basal cell carcinoma. If the tumor is wider than 2 cm , it is probably a more serious tumor. Basal cell carcinomas of the ears, nose, and eyelid may also be of more concern, regardless of the size.
There is a staging system for squamous cell carcinoma. Large tumors that are thicker than 2 mm, invade the nerve structures of the skin, occur on the ear, and have certain worrisome characteristics under the microscope are of more concern. If the tumor metastasizes to a site at some distance from the primary tumor, the cancer is likely to be a dangerous tumor.

Squamous Or Basal Cell Cancer: Which One Is Worse
Skin, the largest organ of the human body, protects us from infections, injuries and helps to modulate the body temperature. Also, the organ stores water and fat and is responsible for producing vitamin D. You might have studied in your school that skin is made up of three layers, i.e., the epidermis, dermis, and hypodermis. As we know, the epidermis is the outermost layer of the skin, while the dermis and hypodermis are the inner layer of the skin and the deep layer of the fat, respectively.
The abnormal growth of skin cells is known as skin cancer. It generally develops on skin exposed to the ultraviolet rays of the sun. You would be surprised to learn that more than 3 million people in the United States are diagnosed with skin cancer, making it the countrys most common type of cancer. If found at an early stage, the disease can be treated with medication, procedures provided by a dermatologist , or a surgeon.
Primarily, there are four types of skin cancer: basal cell carcinoma, squamous cell carcinoma, Merkel cell cancer, and melanoma, but basal and squamous cell cancer are the most common types. Lets find out more about these diseases.

Overview and Symptoms
Basal cell carcinoma symptoms may include:
- an open sore that wont heal
- a reddish patch of irritated skin
- a shiny red or pink bump
- a shiny scar-like bump
Basal Cell Carcinoma Diagnosis
If you have any skin concerns like those mentioned above, its important to see a dermatologist. Ultimately, the only way to diagnose basal cell carcinoma is through a skin biopsy. The skin patch will be removed and sent to a pathologist for review under a microscope to check for cancer cells.

What Makes Yale Medicines Approach To Basal Cell Carcinoma Unique
Yale Medicine receives referrals from community dermatologists all over the country. We receive a very high volume of referrals, so regardless of how unusual the case may be, it’s likely we’ve seen it before, says Dr. Christensen. We work closely with a team of specialized skin pathologists in our dermatopathology lab who evaluate skin samples that could be cancerous or pre-cancerous. Then, our dermatologic surgeons use their expertise to safely remove these spots.
What Are Signs And Symptoms Of Basal Cell Skin Cancer
Basal cell carcinoma typically occurs on areas of the skin exposed to the sun, such as the face, around the eyes, ears, head and scalp, and neck. In rare cases, basal cell cancer may occur on the hands.
Characteristics of the tumors may include the following:
- A pearly white bump
- Spider veins visible on the surface
- Waxy skin growths with raised border and depression in the center
- Flat, scaly patches
- They may bleed, especially if injured.
- Oozing or crusting
- Slow growing: 0.5 cm in 1-2 years
- Black-blue or brown areas

Basal Cell Cancer Of The Head And Neck Treatment
Surgery is the preferred method of treatment for basal cell cancer. Radiation is an alternative when surgery is not desirable because of cosmetic concerns or medical reasons. Many early stage small basal cell cancers can be removed by Mohs surgery, which is a technique that spares normal tissue through repeated intraoperative margin testing, removing only the cancer and leaving adjacent normal tissue. Excision, curettage and desiccation, and cryosurgery can also be used to remove the cancer while sparing normal tissue. Large tumors and tumors with nerve or lymph node involvement are not suitable for Mohs surgery and require a multimodality approach to treatment with formal surgical resection and adjuvant radiation or chemotherapy. Larger tumors require reconstruction, which can be done at the time of surgery if margin status is clear.
Patients with high-risk tumors should meet with a radiation therapist to discuss postoperative radiation. In patients with high-risk tumors who are not surgical candidates, systemic treatment with chemotherapy that inhibits the Hedgehog pathway of tumor progression has been shown to be effective. Such cases require multidisciplinary care by a team of surgeons, radiation oncologists and medical oncologists.

Enhancing Healthcare Team Outcomes
An evidence-based approach to basal cell cancer
Basal cell cancer is relatively common. Patients often first present to the primary care provider with complaints of an abnormal skin lesion. When diagnosed early, it has an excellent prognosis, but if there is a delay in diagnosis, the tumor can advance and lead to significant morbidity. Basal cell cancer is best managed by an interprofessional team that includes a dermatologist, mohs surgeon, plastic surgeon, nurse practitioner, primary care provider, and a dermatopathologist. Basal cell carcinomas typically have a slow growth rate and tend to be locally invasive. Tumors around the nose and eye can lead to vision loss. In most cases, surgical excision is curative. However, because recurrences can occur, these patients need long-term follow up.
What Does Skin Cancer On The Ear Look Like
Being aware of early skin cancer on ear symptoms is the most beneficial step toward early detection and treatment. There are different symptoms of ears cancer caused by skin and variations in the way it may appear.
Symptoms of skin cancer on the ear include scaly skin or small white bumps on the outer ear skin changes around the ear canal or outer ear should be examined by a dermatologist immediately.
As the skin cancer on the ear continues to grow it could appear as:
- Lesion or open sores
The skin cancer growths can be swollen or crusty according to their severity, and there is a chance of puss. Although skin cancer generally develops slowly, it is able to be spread to other areas of the body when left untreated, particularly around the ears, and eventually the face.
You should perform an annual skin examination in order to stay aware of any changes in your appearance. You can visit the hospital to consult a skin cancer specialist in Coimbatore.

What Does Bcc Look Like
BCCs can look like open sores, red patches, pink growths, shiny bumps, scars or growths with slightly elevated, rolled edges and/or a central indentation. At times, BCCs may ooze, crust, itch or bleed. The lesions commonly arise in sun-exposed areas of the body. In patients with darker skin, about half of BCCs are pigmented .
Its important to note that BCCs can look quite different from one person to another. Visit our BCC Warning Signs page for more images and information on BCC signs, symptoms and early detection strategies.
Please note: Since not all BCCs have the same appearance, these photos serve as a general reference to what they can look like. If you see something new, changing or unusual on your skin, schedule an appointment with your dermatologist.
An open sore that does not heal
A shiny bump or nodule
A reddish patch or irritated area
A scar-like area that is flat white, yellow or waxy in color
A small pink growth with a slightly raised, rolled edge and a crusted indentation in the center
Can You Die From Basal Cell Carcinoma
Death from either basal cell or squamous cell cancers is quite rare. Statistics for these types of skin cancer arent tracked by cancer registries, so its difficult to have specific numbers, but its thought that less than 2,000 people in the U.S. die from both basal cell and squamous cell carcinomas each year.
These deaths are predominantly in elderly people who have not had their skin checked in a long time and cancer has grown quite large.
Considering there are over 4 million diagnosed cases of basal cell carcinoma each year in the U.S. , the risk of death from this form of skin cancer is quite low.
