Precancerous Skin Lesions: Prevent Them Before They Turn Cancerous

Friday, 02 May 2014 01:20 AM

In the U.S., skin cancer is the most common of all cancers. Skin cancer is mainly of three types: melanoma, basal cell cancer, and squamous cell carcinoma. Out of these three skin cancers, melanoma is the most dangerous. Melanoma is less common than the other two varieties of skin cancer. Melanoma develops in the melanocytes in the skin. All these skin carcinomas generally start as minor skin lesions. Some precancerous skin lesions have the potential to develop into skin cancer. Moles are the commonest skin lesions turning into carcinoma.
Moles are mostly benign and remain harmless during one’s lifetime. Although not all these skin lesions lead to skin carcinoma, there is a need to remove these skin lesions in time. Atypical mole called dysplastic mole is one such skin lesion that needs to be removed. These moles are located over the chest, breasts, legs, and back. One should suspect carcinoma-causing moles if there is a change in color, shape, and size of the benign mole. Surgical excision is advised in these moles.
Lentigo meligna is another skin lesion that can lead to skin carcinoma over time.
Acitinic keratosis, known as solar keratosis, is a skin lesion which is rough and has the potential to cause skin carcinoma. These skin lesions appear due to overexposure to the sun. These skin lesions turn into squamous cell carcinoma in 5 percent of the total cases. Doctors always recommend early management to prevent them from turning into carcinoma.
Cutaneous horns found in fair-skinned people are other skin lesions which may cause carcinoma.  
Melanoma is also known as malignant melanoma and cutaneous melanoma. Some genetic syndromes are also linked with melanoma-type skin cancer. One of the main signs of melanoma is change in the size or shape of the moles. The chest and back in men and legs in women are the main sites affected by melanoma. Overexposure to ultraviolet light from the sun is one of the causes of most skin cancers. Melanoma is categorized into many stages, namely, Stage zero, Stage 1, Stage 2, Stage 3, Stage 4, and recurrent melanoma. Stage zero is limited to epidermis and is cured with surgical treatment. In Stage 1, surgical treatment along with interferon is recommended. Stage 2 is managed with surgical treatment and lymph node removal. For Stage 3, surgical removal of melanoma, lymph node removal and chemotherapy are planned. Stage 4 treatment is very difficult and is done with surgery, radiation, and targeted chemotherapy. Early treatment can increase the survival rates in melanoma. Cryosurgery, electrical burning, excision, and laser are used to get rid of these skin lesions.

Skin cancer is often preceded by some precancerous skin lesions. Though many conditions like blemishes and moles are benign, there is a need to be vigilant about them and prevent them from turning into dangerous skin carcinoma.
