|What is tumor Skin?|
Skin tumor growths on the skin caused by abnormal cells. There are various types of skin tumor cells derived from different skin layers. Three main types of skin tumor are basal cell carcinoma, squamous cell carcinoma and melanoma. Melanoma is the most dangerous skin tumor where they grow and spread to other organs of the body quickly.
Skin is the outer lining of the body. It protects us from heat and light, injury, and infection. It regulates body temperature and stores water, fat and vitamin D. With a weight of about 2.73 kg (6 lb), skin is the body’s largest organ. It is composed of two main layers: the outer skin layers and layers of skin. The outer skin (epidermis) is formed from a flat scale like cells called squamous cells. Under the squamous cells are round cells called basal cells. The deepest part of the epidermis also contains melanocytes. These cells produce melanin, which gives color to the skin. Layer of skin (dermis) contains blood and lymph vessels, hair follicles, and glands. These glands produce sweat, which helps regulate body temperature, and sebum, an oily substance that prevent cracks. Sweat and sebum reach the skin surface through pores.
|What is a skin tumor symptom?|
Skin tumor develops primarily on areas of sun-exposed skin, including the scalp, face, lips, ears, neck, chest, arms and hands, and on the legs in women. Skin tumor affects people of all skin tones, including those with darker complexion. There are several symptom of skin tumor:
Basal cell carcinoma symptom
Usually basal cell carcinoma occurs in sun-exposed areas of body, such as neck or face. Basal cell carcinoma may appear as a pearly or waxy bump and a flat, flesh-colored or brown scar-like lesion.
Squamous cell carcinoma symptoms
Squamous cell carcinoma occurs on sun-exposed areas of body, such as face, ears and hands. People with darker skin are more likely to develop squamous cell carcinoma on areas that are not often exposed to the sun. Squamous cell carcinoma may appear as firm, red nodule and flat lesion with a scaly, crusted surface.
Melanoma can develop anywhere on body, in otherwise normal skin or in an existing mole that become tumor. Melanoma most often appears on the face or the trunk of affected men while in women, this type of tumor most often develops on the lower legs. Melanoma signs include a large brownish spot with darker speckles, a mole that changes in color, size or feel or that bleeds, small lesion with an irregular border and portions that appear red, white, blue or blue black.
|What is risk factor of skin tumor?|
- Excessive exposure to ultraviolet light
Excessive exposure to ultraviolet light (UV) radiation from the sun can damage DNA and cause skin cancer incidence. Use sunscreen excessive to darken skin color will increase a person’s risk of skin cancer.
- Skin types
Individuals with light skin types have a higher risk than those have dark skin color.
- Genetic factors
There are a range of genetic diseases that cause patients more sensitive to sunlight. For example, patients suffering from xeroderma pigmentosum cannot restore cells damaged skin after exposure to sunlight, as the lack of a mechanism to improve the damaged DNA as compared with normal persons. As a result, the patient’s skin is very sensitive and often burn if exposed to sunlight. They are more likely to suffer from cancer at a young age. However, such a genetic disease is extremely rare.
- Lack of immune system
Patients seeking treatment after organ transplantation have a higher risk of getting skin cancer.
- Human Papilloma Virus Infection?
This viral infection plays an important role in the formation of cancer, particularly cancers of the vulva and penis.
- Exposure to arsenic and radiation
Exposure to chemicals such as arsenic can increase a person’s risk of skin cancer. Rates of arsenic higher than the permissible level can be obtained from drinking contaminated well water. Other sources of arsenic poisoning are from traditional medicines. In addition, an exposure to radiation also increases the risk of skin cancer.
Smoking is also linked to the occurrence of skin cancer.
- Chronic ulcers
Individuals who have an ulcer that does not heal after years or a certain scar may have a tendency to skin cancer in the long run.
