Skin cancer

Skin cancers are cancers that come from the skin. This is due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. There are three main types of skin cancer: basal cell carcinoma (BCC), squamous skin cancer and skin cancer. The first two are less common skin cancer and are known as non-melanoma (NMSC). Basal cell carcinoma develops slowly and can damage surrounding tissues, but is unlikely to spread to remote areas or cause death. It often appears as a painless area of the skin, which may shine with small blood vessels that overreact or may appear as an elevated area with an ulcer. Scarf skin cancer is more susceptible to proliferation. It usually appears as a solid mass with crusty top, but can also form a sore. Melanoma is the most aggressive. Signs include moles that changes in size, shape, color, irregular edges, have more than one color, itching or bleeding.

a. Symptoms

There are several different indications of skin cancer. These include variations in the skin that do not heal ulcers of skin, skin discoloration and changes in existing moles, rough edges in the mole and extended mole.

b. Types of Skin Cancer

  • Basal cell carcinoma: Basal cell carcinoma (BSK) usually presents a pearly, smooth, raised form on sun-exposed skin of the head, neck, or shoulders. Sometimes small blood vessels (called telangitasias) can be seen inside the tumor. In general, scabies and bleeding in the middle of the tumor is often mistaken for an ulcer that does not heal. This type of skin cancer is the less dangerous and with appropriate treatment can be completely eradicated, often without leaving scars.
  • Skin cancer of the scalpel: Carcinoma of the skin (doubt) is usually red, scaly, thick spot on exposed sun skin. Some nodules are solid and fixed with a form of keratocanthomas. Bleeding and bleeding may occur. When there is no doubt, it can become a big block. Squamous cells are the second most common skin cancer. It’s dangerous, but not as dangerous as skin cancer.
  • Melanoma: Most skin cancers consist of several colors ranging from brown to black. Some melanomas are pink, red or fleshy. These skin cancers are called melanocytes and
    tend to be more aggressive. Early warning signs of malignant melanoma include changes in the size, shape, color or height of the mole. Other signs are the emergence of a new mall during puberty or pain, itching, ulceration, redness of the site or bleeding on the site.

c. Causes

  • UV exposure is the main environmental cause of skin cancer.
  • Tobacco
  • HPV infections increase the risk of squamous cell cancer of the skin.
  • Certain genetic syndromes including congenital malformations (moles) characterized by the presence of moles (moles or moles) of variable size present at birth or appearing within 6 months of birth. Nevi over 20 mm (3/4 “) have a greater risk of becoming cancerous.
  • Chronic wounds are not therapeutic. Margolin’s ulcer is called based on its appearance and can develop scaly skin cancer.
  • Ionizing radiation, such as X-rays, environmental carcinogens, synthetic UV rays (e.g. tanning beds), aging and the light color of the
  • Now people who use synthetic tanning pools are putting the most at risk of skin cancer. Alcohol consumption, especially the excessive consumption of alcohol increases the risk of sunburn. The use of many immunosuppressive drugs increases the risk of skin cancer. Cyclosporin A, a calcinurine inhibitor, for example, increases the risk of about 200-fold and azathioprine about 60-fold.
