Malignant melanoma Prevention and Prognosis

Prevention for Malignant melanoma is avoid the sun, especially for those high-risk groups. Try to early detection, early diagnosis, early treatment.

1. To occur in vulnerable parts of the nevus of friction should be taken biopsy. Nagymaros nevi such as children in the waist, often by the belt friction and extrusion, all should be removed as soon as possible. If there is a total removal of difficulties, not malignant transformation mole in Nagymaros before removal of the main part of the middle as far as possible, both sides of the suture, such as the skin surrounding paternity Larsson, and then removed the rest of the mole until the total removal of date, in order to prevent malignant transformation. resection specimens of each must be sent to pathology. If There are malignant, should be all removed, the skin graft surgery.

2. Should not use drugs or corrosion completely frozen to stimulate mole. Once frozen and repeated several times can not, there is a danger, because mole often occur because of trauma to stimulate malignant transformation. It is reported that is was due to a frozen not thorough and the occurrence of malignant transformation. about 30% ~ 50% of malignant melanoma with the outside world and stimulate the growth of related. If the needs of beauty should be a one-time removal of moles, it is more safe and reliable. resection combined with frozen to a complete, should not have fractionated resection, resection of the specimen should be sent to pathology.

3. Color malignant mole information:
11) increasing the volume of color stains, pigments, or deep or shallow.
2) color expansion of the surrounding mole shows radial.
3) color stains cause pain or discomfort, a small number of surface exudate.
4) color mole regional lymph nodes, looming black blue.
5) blue-black patients urine solution.

Malignant melanoma prognosis:
1. the depth of tumor invasion: Tumor thickness and prognosis is closely related to the primary tumor ≤ 0.75mm the 5-year survival rate was 89%, ≥ 4mm primary foci were only 25%.

2. lymph node metastasis: l ~ 3 lymph nodes with metastasis from the 5-year survival rate was 41% ~ 58%, 4 transfer for more than 8% ~ 26%, while the thickness of lesions and lymph node metastasis are prognostic an important factor, but the lymph node metastasis or prognosis seems to be a greater impact.

3. the lesion site: In accordance with the clinical analysis of malignant melanoma occurred in different parts of its effect is also different, occurred in the trunk is generally believed that the worst prognosis, followed by those located in the head and neck, limbs are good at.

4. surgical method: the standard of removal scope of Malignant melanoma, ≤ 0.75mm thickness lesions were removed from the tumor edge of the scope of 2cm ~ 3cm. Thickness> 0.75mm and ≤ 4mm for 3cm ~ 4cm, thickness> 4mm from 5cm away from the edge of extensive tumor resection. Local excision is not appropriate, so that the local recurrence rate was as high as 27% ~ 57%, in the event of local recurrence for a wide range of very complete resection can not be effective; the handling of regional lymph nodes as well, a non-compliance with regional lymphadenectomy, regular promotion of tumor spread to the whole body.

5. age and gender: a rare juvenile better prognosis malignant melanoma, 45 years of age in patients with malignant melanoma of older patients with good prognosis. In women with sex on the prognosis is better than men.
