Squamous cell carcinoma (SCC) skin cancer develops from keratinocytes, flat, scale like skin cells that lie under the top layer of the

epidermis. The majority of squamous cell carcinomas occur on sun exposed areas, especially the forehead, temple, ears, neck, and back of the hands. People who have spent considerable time sunbathing may develop them on their lower legs.
Squamous cell carcinoma skin cancer occurs in many different organs, such as mouth, prostate, lung, lips, tongue. Squamous cell carcinoma (SCC) also called Bowens’ disease, this skin cancer also able to spread away through blood vessels. This skin cancer can break away, leak, or spill from a primary tumor, enter lymphatic and blood vessels, circulate through the bloodstream, and settle down to grow new skin cancer within normal tissues elsewhere in the body, or called Metastasis. Metastasis is one of three hallmarks of malignancy (contrast benign tumors).
This cancer skin patients vary with race, gender, age, genetics and geography. In gender, male have 2:1 ratio compare to females, since most women are love to sunbathe and ignoring the danger of skin cancer. Caucasians are more likely to be affected by skin cancer, especially those with fair Celtic skin, if chronically exposed to UV radiation. Exposure to arsenic in well water or from industrial sources may significantly increase the risk of squamous cell carcinoma skin cancer.

Squamous cell carcinoma may be classified into the following types:

• Adenoid squamous cell carcinoma (Pseudoglandular squamous cell carcinoma)
• Clear cell squamous cell carcinoma (Clear cell carcinoma of the skin)
• Spindle cell squamous cell carcinoma
• Signet-ring cell squamous cell carcinoma
• Basaloid squamous cell carcinoma
• Verrucous carcinoma
• Keratoacanthoma

Squamous cell is the part of the skin that become the place one of skin cancer types and the second most common form of non-melanoma cancer that is squamous cell carcinoma (SCC). Squamous cell epithelium consists of very thin and flattened hexagonal cells which closely fitted like tiles of a floor. The nucleus is oval and lies in the center of the cell. This epithelium is found on the superficial layer of the skin, in the lining of the body cavity, blood vessels, walls of Bowman’s capsule. Cancer that occurs in this cell part aside of squamous cell carcinoma are basal cell carcinoma and other adnexal tumors.

Squamous cell carcinoma will not causing more problems if it diagnosed and treated early. However, if this skin cancer left untreated, squamous cell carcinoma can grow large or spread to other parts of your body, causing serious complications.

The cause of squamous cell carcinoma is sun exposure; the incidence of this skin cancer is rising every year. Most squamous cell carcinomas result from prolonged exposure to ultraviolet (UV) radiation, either from sunlight or from tanning beds or lamps. The best things to prevent squamous cell carcinoma by avoiding UV light as much as possible. Sunscreen is an important part of a sun-safety program, but by itself doesn’t completely prevent squamous cell carcinoma or other types of skin cancer.

Just in this year, over 1 million people diagnosed with squamous cell carcinoma in United States. The risk of developing squamous cell carcinoma increases when a person also has one or more of these risk factors:

• Fair skin.
• Blonde or red hair; blue or green eyes.
• History of indoor tanning.
• Diagnosed with actinic keratosis (AKs).
• Family history of skin cancer.
• Weakened immune system (immune-suppression).
• Received radiation therapy.
• History of exposure to coal tar products or arsenic.

The risk of developing squamous cell carcinoma also increases with age because each exposure to harmful UV rays causes more damage to the skin. As this damage accumulates, the risk of developing skin cancer grows.

• If left untreated, Squamous Cell Carcinoma can grows into a large mass.
• This cancer is more common in women than in men.
• Invasive squamous-cell carcinoma has the potential to recur and metastasize.
• Arsenic from industry area can increase its risk factor.
• The direct DNA damage is responsible for causing of Squamous cell carcinoma.
• Sunscreen shows can protect from SCC.
• SCC makes skin cell cannot die, rather than stay in the place while the healthy skin cell continuously growing.
• This skin cancer tends to attack on the face, such as lips and ears.
• Squamous cell carcinoma can be characterized as either in situ (confined to the original site) or invasive, depending on whether the cancer invades underlying tissues; only invasive cancers are able to spread to other organs and cause metastasis. Squamous cell carcinoma in situ are also called Bowen’s disease.
• The incidence of SCC increases with age and the peak incidence is usually around 66 years old.
• This skin cancer can be mistaken with keratoacanthoma or a wart.
• Large lesions (>2 cm in diameter) recur at a rate of 15 percent, which is twice that of smaller lesions, and they metastasize at a rate of 30 percent, three times that of smaller lesions.
• A long term prognosis of Squamous cell carcinoma often poor.
• The treatment that offers the highest rates of cure for patients with high-risk primary or recurrent squamous-cell carcinoma is Mohs’ micrographic surgery.

Squamous Cell Carcinoma Skin Cancer Symptoms

Squamous cell carcinoma skin cancer symptoms usually begin as a small nodule and as it enlarges the center becomes necrotic and sloughs and the nodule turns into an ulcer.

• Bump that may have rough, scaly surface and flat reddish patches, it’s a common symptom of skin cancer squamous cell carcinoma
• On the lip, the tumor forms a small ulcer, which fails to heal and bleeds intermittently
• The lesion caused by SCC is often asymptomatic
• The tumor may be in the form of a hard plaque or a papule, often with an opalescent quality
• Ulcer or reddish skin plaque that is slow growing
• Usually the tumor presents as an ulcerated lesion with hard, raised edges
• The tumor commonly presents on sun-exposed areas such as back of the hand, scalp, and lip
• Evidence of chronic skin photo damage, such as multiple actinic keratosis (solar keratosis)

Unlike Basal Cell Carcinoma (BCC) skin cancer, Squamous Cell Carcinoma (SCC) skin cancer has a high risk of metastasis to another organ. Risk of metastasis is higher in SCC arising in scars, on the lower lips or mucosa, and occurring in immune-suppressed patients. About *one-third of lingual and mucosal tumors metastasize before diagnosis (these are often related to tobacco and alcohol use).

Skin Cancer

Squamous cell carcinoma skin cancer caused some damage to the underlying skin cells and slowly a lump or tumor will develop right under the skin. Squamous Cell Carcinoma tends to attack on the face, such as lips and ears. It can manifest itself as a bump that is thickened, scaly, red, or crusty. It could resemble a wart. If it occurs on the rim of the ear or the lip it seems to become more aggressive in its growth.

Skin cancer treatment

The treatment for squamous cell cancer carcinoma is mainly use surgery, although few selected cases are treated with topical medication.  Surgical excision with a free margin of healthy tissue is a frequent treatment modality. Radiotherapy, given as external beam radiotherapy or as brachytherapy (internal radiotherapy), can also be used to treat squamous cell carcinomas.

Treatment for skin cancer

There are other option of Squamous Cell Carcinoma Skin Cancer Treatment:

1. Moh’s surgery is still used, even though the cure rate is not very high.
2. Radiation therapy often used afterward in high risk cancer or patient types.
3. Electrodessication and curettage or EDC, usually use to treat squamous cell carcinoma that known to be non-aggressive.
4. Imiquimod (Aldara) has been used with success for squamous cell carcinoma in situ of the skin and the penis, but the morbidity and discomfort of the treatment is severe. An advantage is the cosmetic result: after treatment, the skin resembles normal skin without the usual scarring and morbidity associated with standard excision. Imiquimod is not FDA-approved for any squamous cell carcinoma.

Squamous Cell Carcinoma is the second most common type of skin cancer after Basal Cell Carcinoma. It concerns the older cells that have been pushed to the surface of the epidermis by the continuous healthy growth of basal cells deep within the skin. To put it simple, because of Squamous Cell carcinoma, the old skin cell doesn’t die and replaced, but it still there while the healthy one still continue growing of course with this squamous cell carcinoma skin cancer.

SCC

This type of skin cancer caused some damage to the underlying skin cells and slowly a lump or tumor will develop right under the skin. Squamous Cell Carcinoma tends to attack on the face, such as lips and ears. It can manifest itself as a bump that is thickened, scaly, red, or crusty. It could resemble a wart. If it occurs on the rim of the ear or the lip it seems to become more aggressive in its growth.

Squamous Cell Carcinoma

Squamous Cell Carcinoma (SCC) seems to be a skin cancer that affects more men than women. Also, this type of skin cancer occurs more often with individuals who are fair-skinned and who are older than sixty years of age. However, Squamous Cell Carcinoma (SCC) can affect anyone who lives in a warmer climate or whose work and/or play keep them outdoors in the sun a great deal.

Skin Cancer

Squamous cell carcinoma skin cancer has peculiar character, such as this type of skin cancer tends to be less invasive if found on skin that is sun-damaged by sun exposure than if it is found on a part of the body that does not normally get the same exposure to the sun. Doesn’t matter which one squamous cell carcinoma caused, it still need a lot of concern.

Causes

The causes of squamous cell carcinoma can include such carcinogenic sources such as:

1. the accumulated lifetime exposure to the sun’s harmful rays,
2. a reaction to treatments for psoriasis that includes using Psoralen or Ultraviolet A radiation,
3. exposure to radiation from radiotherapy,
4. chemicals such as arsenic,
5. the human papilloma virus, and
6. Smoking.

Some genetic factors can also play a role in causing squamous cell carcinoma skin cancer if the individual inherits the DNA defect called xeroderma pigmentosa wherein the cells have difficulty repairing themselves. Or they have very little pigment coloring such as in albinism that leaves them extremely sensitive to the sun.

2

Other problem areas are if a person has wounds from an injury or other thermal type burn that refuses to heal well or if they are more vulnerable due to taking anti-rejection drugs after a transplant and their immune system is greatly lowered.

3

As with basal cell carcinoma this cancer is treated according to the location, size and grade of the tumor or lesion. The age and health of the patient is also considered. The treatment consists basically of surgical options. Simple excision may be used if the area is small and has not spread.

4

If the carcinoma is larger, on or near sensitive areas such as an eyelid, has been left untreated for a long time, or is in danger of recurring the doctor may opt to use what is called the Moh’s Technique which means that he will slowly remove the lesion or tumor by slicing it in layers. He or she will do this until they are certain to have gotten all the tumor and they have reached healthy tissue.

5

At times the physician may feel that radiation is needed to be certain that any surrounding cancer cells are killed or it may be necessary if the lymph nodes are at risk. It may also help with larger tumors and be a replacement for surgery if the patient is unable or unwilling to accept it.

6

In some cases where the cancer may have spread to other parts of the body it will be necessary to include chemotherapy to kill the radical cells.

There are other spots, called seborrheic keratoses, that are not caused by sun exposure and have no relationship to skin cancers. These are raised brown lesions that may appear on any area of the skin. They also often run in families. Seborrheic keratoses may be mistaken for an actinic keratosis.

• When staying in the sun for long periods of time, use a sun protection clothing, hats, sunscreen clothing, or tan spray.
• Frequently applying powerful sunscreen products with SPF ratings greater than 30 and that also block both UVA and UVB light.
• Wearing sun protective clothing such as hats, long-sleeved shirts, long skirts, or pants.
• Avoiding sun exposure during noon hours is very helpful because ultraviolet light is the most powerful at that time.

Actinic Keratosis can be known by it’s characteristic that easily to be spotted, that are:

1. An actinic keratosis is a small, rough spot occurring on skin that has been chronically exposed to the sun.
2. Actinic keratosis is also known as a solar keratosis.
3. Actinic keratoses occur most commonly in fair-skinned people after years of sun exposure.
4. Common locations for actinic keratoses are the face, scalp, back of the neck, upper chest, as well as the tops of the hands and forearms.
5. Actinic keratoses are precancerous, which means they can develop into skin cancer.
6. Doctors can usually diagnose an actinic keratosis just by examining it.
7. The best treatment for an actinic keratoses is prevention by minimizing sun exposure.
8. Treatments for actinic keratoses include cryosurgery, cutting or burning, 5-fluorouracil, imiquimod, diclofenac, and photodynamic therapy.
