It is the most common cancer in Brazil and accounts for 25% of all malignant tumors recorded in the country. Shows high cure rates if detected early. Among the tumors of the skin, non-melanoma type is the higher incidence and lower mortality.
Skin cancer is more common in people over 40 years and is relatively rare in children and blacks, except those already suffering from skin diseases earlier. People with fair skin, sensitive to the action of sunlight, or with previous cutaneous diseases are the main victims.
As the skin - the largest organ of the human body - is heterogeneous, cancer of non-melanoma skin tumors may present in different lineages. The most common are basal cell carcinoma, which accounts for 70% of diagnoses, and epidermoid carcinoma, representing 25% of cases. Basal cell carcinoma, although more common, it is also the least aggressive.
Treatment
Surgery is the best treatment both in cases of basal cell carcinoma and squamous cell carcinoma. However, the basal cell carcinoma of small extent may be treated with topical medication (ointment) or radiotherapy. Already against squamous cell carcinoma, the usual treatment combines surgery and radiation.
Prevention
Skin tumors are related to some risk factors, especially exposure to ultraviolet rays of the sun. People who work under direct sunlight are more vulnerable to skin cancer nonmelanoma.
Avoid sun exposure from 10 am to 16h and always use sunscreen with SPF 15 or more, plus hats, umbrellas and sunglasses.
Other risk factors include exposure to chemicals (arsenic) and ionizing radiation, chronic irritation process (Marjolin ulcer), genodermatoses (xeroderma pigmentosum, etc..).
This type of cancer is more common in adults, with peak incidence around age 40. However, with the constant exposure to sunlight young, the average age of patients is decreasing.
Skin self-examination
What is skin self-examination?
It is a simple method for early detection of skin cancer, both melanoma or non-melanoma. If diagnosed and treated when the tumor has not invaded deeply into the skin, skin cancer can be cured.
When do?
By doing the self-exam regularly, you will become familiar with the normal surface of your skin. It is useful to note the dates and appearance of the skin on each exam.
What to look for?
• Stains pruritic (itchy), scaly or bleed
• Signs or moles that change size, shape or color
• Sores that do not heal in 4 weeks
It should be borne in mind ABCD transformation of a melanoma in paints, as described below:
• Asymmetry - one half than the other
• Jagged edges - poorly defined boundary
• Variable color - multiple colors within the same lesion: black, brown, white, red or blue
• Diameter - larger than 6 mm
How do?
1) In front of a mirror, with arms raised, examine your body from the front, back and sides right and left;
2) Bend your elbows and look carefully at the hands, forearms, arms and underarms;
3) Examine the parts of the front, rear and sides of the legs beyond the genital region;
4) Sitting closely examine the plant and the balls of the feet, as well as between the toes;
5) With the aid of a hand mirror and a brush or dryer, examine the scalp, neck and ears;
6) Finally, even with the aid of hand mirror, examine your back and buttocks.
