What is the superficial spread of melanoma?
Surface spread of melanoma (SSM) is a type of skin lesion that can be a precursor of skin cancer. Initially, it seems small and looks similar to a slightly large freckle, but significantly progresses into a larger and more distinctive lesion. Anyone can close this condition regardless of age and sex, although some people are more susceptible than others. Although his prognosis is generally considered to be a promising and not endangering life, the condition may be fatal if it is not treated. Nodular melanoma accounts for about 15 percent of cases, Lentigo Maligna melanoma for about 10 percent and an acral lentiginous melanoma for about 5 percent. The latter is considered to be the most threatening life of all forms of melanoma. Because the surface spread of melanoma is quite prominent, it is still the main cause of cancer death despite its positive prognosis.
The condition is most common in women, although men can also download it. Females usually find lesions on their feet while men generally find lesions scattered between the upper fuselage, especially mEzi neck and pans. Surface spread of melanoma usually occurs by post-puberts and tends to be predominant among the Caucasians than people of an ethnic environment. Moreover, it is more common in people who have 100 or more moths on the body.
The two phases of the surface spread of melanoma indicate both the appearance of the condition and the threat that represented its carrier. The initial phase is known as a radial phase in which the lesion is first formed on the skin. These lesions seem small and thin and can stay at this stage for several months or even years. The radial phase is the least significant threat of cancer.
The second phase of Condition, called the vertical growth phase, turns out to be a significantly more threatening life. The lesions grow more than 0.25 inches (6 mm) and move deeper to the surface of the skin, which may cause pain, skin irritation, leakage or bleeding. Melanoma can spread to the surrounding tissue of the skin and its pigmentation candarken. Mild reduction of this pigmentation sometimes occurs when the immune system attempts to fight the condition, but melanoma still exists and requires treatment.
Many different factors contribute to the probability of closing the surface propagation of melanoma. Patients often have siblings or parents with a condition. Other uncontrollable factors, such as a weak immune system or rare hereditary skin disease called Xeroderma pigmentosum, may pose another risk. The sun, a more manageable factor, increases the likelihood of melanoma surface spread, especially during adolescence.
It is recommended that the dermatological signs of this condition be consulted. The surface spread of melanoma is generally diagnosed with biopsy, although sometimes X -rays, computer axial tomography (CT), magnetic resonance imaging (MRI), ultrasound and other procedures are used. The condition is commonly treated with surgical removal, which significantly reduces the risk of its development on potentially fatal cancer tocan.
