Not all changes in the skin are cancer.<br /> Melanoma is a disease of the skin in which cancer cells are found<br />in the skin that colour the skin(melanocytes).Melanoma usually occur<br />in the adults,rarely it occurs in the children.<br /> Skin is made of two layers, the epidermis(top layer) and dermis<br />(the inner layer).Melanocytes are found in the epidermis and they<br />contain melanin which gives the skin its colour.Melanoma is of two<br />types cutaneous and malignant.<br /> Melanoma is a more serious type of cancer than the more common skin<br />cancer (or)squamous cell cancer,which begin in the basal or squamous<br />cells of the epidermis.Melanoma can be treated early if<br />diagonoised.Melonama spreads to other parts of body through the blood<br />or lymph system.<br /> Cancer occur when normal cell s undergo a transformation during<br />which they grow and multiply without normal controls.As cells<br />multiply, they form a mass called a tumour.Tumours of the skin are<br />called lesions.<br /> Tumours are cancers only if they are malignant.This means that<br />they encroach on and invade neighbouring tissues because of their<br />uncontrolled growth.<br /> Tumours may also travel to remote organs via the blood stream or<br />lymphatic system.This process of invading and spreading to other<br />organs is called metasis.Tumours overwhelm surrounding tissues by<br />invading their space and taking the oxygen and nutrients they need to<br />survive and function.elavenilhttp://www.blogger.com/profile/03220966324410198341noreply@blogger.com0
