Malignant melanoma bark cancer Stages and prognosis

Malignant melanoma is the best serious anatomy of bark cancer as metastasis can occur early and it causes a number of deaths alike in young people. As with other blazons of bark cancer the incidence is continuing to increase, probably because of excessive expoabiding to sunlight. The history of childawning sun expoabiding and intermittent sun expoabiding appaerial to be allotmenticularly important in the development of malignant melanoma.

Other accident actualityors include atypical birthmark syndrome, giant congenital melanocytic naevi, lentigo maligna and a positive family history of malignant melanoma. Malignant melanoma is commoner in backwardr activity but abounding young adults are additionally affected.

Diagnosis of melanoma is not almeans accessible but the clinical signs advice distinguish malignant from benign birthmarks. Examination with epiluminescence microsarchetype can further advice in detecting malignant lesions.

Four clinical blazons of Malignant melanoma exist:

Lentigo maligna melanoma is where a patch of lentigo maligna develops a papule or nodule signalling invasive tumour.
Superficial spreading malignant melanoma is a large collapsed irregularly pigmented lesion which abounds backwardrally beahead vertical invasion develops.
Nodular malignant melanoma ( Fig. 22.33 ) is the best aggressive blazon. It presents as a rapidly abounding pigmented nodule which bleeds or ulcerates. attenuately they are amelanotic (non-pigmented) and can mimic pyogenic granuloma.
Acral lentiginous malignant melanoma arises as pigmented lesions on the approach, sole or under the attach and it usually presents backward.

Treatment of Malignant melanoma

This consists of urgent advanced excision of the lesion. Histological analysis will deterabundance the depth of invasion ('Clark's level') and the thickness of the tumour ('Breapathetic thickness'). These two actualityors advice to predict prognosis and 5-year survival amounts. Excision and histology interpretation should alone be done by experts to enabiding optimum treatment and assessment of prognosis. Metastatic disaffluence is best manage by an oncologist and can involve surgery to lymph bulges, radiotherapy, immunotherapy and chemotherapy.

The role of governments and medical personnel in public alleviateth education to discourage sunbathing and encourage the use of sunscreens is of the utbest importance in bark cancer prevention.
