Skin cancer is a disease in which cancer cells are observed in the outer layers of the skin. This form of cancer is very slow to grow and most often develops on skin revealed to the sun. While skin cancers can be present on any part of the body, nearly 80 percent appear on the face, head, or neck, where they can be disfiguring as well as hazardous. Skin cancers are categorized into one of two classes - nonmelanoma skin cancers and melanoma. Melanoma is the cadaverous form of skin cancer. It is less common in comparison to basal cell or squamous cell skin cancer.
Other forms of skin cancer are rare. This common form of cancer also can happen on areas of the skin not ordinarily exposed to sunlight. Skin cancer locally develops in the epidermis, the outermost layer of skin, so a tumor is generally clearly visible. This makes most skin cancers discernible in the early stages. This type of cancer can look many several ways. The most common sign of skin cancer is a variation on the skin, such as a growth or a sore which won't heal. Betime there may be a small lump.
Like many cancers, skin cancers initiates as precancerous lesions. Skin cancer may also resemble as a flat red spot which is rough or scaly. "Sunburn as a child or young adult maximises your risk of skin cancer." Skin cancer is diagnosed by removing all or part of the development and examining its cells under a microscope. Other, less common causes of skin cancer include repeated exposure to x-rays and exposure to coal tar, arsenic, and other industrial compounds. Some people can prevent skin cancer by avoiding overexposure to the sun and other factors of ultraviolet light, such as tanning lamps.
Melanoma is the most concerned form of skin cancer. It influences deeper layers of the skin and has the greatest potential to spread to other tissues in the body. Though anyone can get skin cancer, the risk is greatest for people who have fair skin that freckles easily - usually those with red or blond hair and blue or light-colored eyes. Skin cancer is a disease which has shown a stationary increase over the past 20 years. Luckily, with early diagnosis and treatment, it remains a very curable disease.
Causes of Skin cancer
The common causes and risk factor's of Skin cancer include the following:
- Ultraviolet (UV) light exposure, most commonly from sunlight.
- Heredity may perform a role.
- People with weakened immune systems are at greater risk of developing skin cancer.
- Exposure to toxic chemicals or as a result of radiation treatments.
- A history of sunburns.
- People who have many moles or abnormal moles called dysplastic nevi are at amplified risk of skin cancer.
Symptoms of Skin cancer
Some sign and symptoms related to Skin cancer are as follows:
- A variation on the skin, such as a growth or a sore which won't heal.
- Occassionally small blood vessels can be visible within the tumor.
- A pearly or waxy bump on your face, ears or neck.
- Crusting and bleeding in the center of the tumour frequently develops.
- Variations in existing moles (size, texture, color).
Treatment of Skin cancer
Here is list of the procedures for treating Skin cancer:
- Your doctor may destroy actinic keratoses and some small, early skin cancers by freezing them with liquid nitrogen (cryosurgery).
- Apply a bounteous amount (about a palmful) and reapply after swimming, toweling dry, or perspiring. Use sunscreen even on hazy or overcast days.
- If the cancer is large, nevertheless, or if it has spread to the lymph glands or elsewhere in the body, major surgery may be required.
- Radiation may devastate basal and squamous cell carcinomas if surgery isn't an preference.
- In more furthered cases of skin cancer,chemotherapy (drugs that kill cancer cells) may be used with surgery to improve cure rates
