Signs of Basal Cell Carcinoma

Basal cell carcinoma is a skin caner that is commonly observed among Caucasians. The cancer is not clinically known to metastasize or kill, but it is locally invasive. Usually concentrated around the head and neck, the cancer shows up in a number of forms. The condition is usually caused, if not genetically transferred, by over-exposure to the direct rays of the sun. Basal cell carcinoma instances have increased in the last three decades and it is believed that 4 our of every 10 Caucasians suffer the onslaught.

Basal cell carcinomas are called so, since they develop within the basal cell layer. The formation of thymine dimers are UV induced and cause DNA damage. Cumulative damage causes cell mutation and depresses the immune system in the afflicted area. This cancer also develops due to the onslaught of basal cell nevus syndrome or Gorlin's syndrome. The mutation of the PTCH1 gene, which is credited with tumor suppression and located within chromosome 9q22.3, inhibits the necessary signaling and causes basal-cell carcinoma.

Signs of Basal Cell Carcinoma:

The condition surfaces in a number of ways, most of which are initially neglected. It is very essential to be attentive to the appearance of:

• Flesh-colored translucent papules that ulcerate in time.
  
  
• Cystic formations that have a central fluid-cavity.
  
  
• Nodular variant that is often mistaken for skin cancer or melanoma.
  
  
• A scar or infiltrative lesion.
  
  
• A scaly patch in the affected area, which is red in color. This form is commonly confused with eczema.
  
  
• Baso-squamoid that develops around the lips and ears. This form has been most responsible for deaths in immuno-suppressed individuals.
  
  
• Fibroepitheliomal skin tag.

Though most features of basal cell carcinoma resemble numerous noncancerous skin psoriasis or eczemas, it is advisable to report any worrisome observation in skin texture to the physician immediately. Other than the above mentioned signs, you should also immediately report:

• A sore that persistently oozes, bleeds, or crusts temporarily and then bleeds again. Any non –healing sore should be addressed immediately to rule out basal cell carcinoma.
  
  
• A red patch that keeps appearing on the face, shoulders, chest and limbs. The pain or itchiness or even painlessness should not be ignored.
  
  
• A nodule that is shiny in appearance, either red, pink or white in color should not be confused with a mole and should be brought to the attention of your doctor.
  
  
• A growth with an elevated border and an indentation that is crusted should not be neglected either. You should also investigate scars with undefined borders.

Diagnosis and Treatment:

Basal cell carcinoma usually occurs on the regions of the body that are regularly exposed to direct sunlight. The onslaught could also be the result of genetic susceptibility. The condition is diagnosed via skin biopsy. In this method, a tissue is extracted for pathological study. The operation for tissue extraction takes place under local anesthesia. The method could either involve a deeper incision to scoop our more tissue or a shave biopsy, in which only the surface tissue is removed. Clinically, without biopsy, it becomes difficult to diagnose the condition, since most variants resemble benign lesions.

The cancer treatment options include standard surgical excision, Mohs surgery, chemotherapy, immunotherapy and radiation, photodynamic therapy, cryosurgery and/or electrodessication and curettage. The chances of overpowering the onslaught of basal cell carcinoma are more, if the appropriate method of treatment is adopted while treating the primary basal cancerous cells. It is recurrence that needs to be avoided at all cost. Basal cell cancer is more common in fair-skinned people, especially those with a family history of cancer. It is a characteristic of the regions closer to the equator and at high altitudes. The cancer could also lead to the development of Nevoid basal cell carcinoma syndrome.
