Luanda — Cervicofacial (neck and face) neoplasia represents 5 to 8 per cent of malignant tumours in adults and children, an incidence that tends to increase in the fifth decade of life, said last Friday in Luanda the specialist in microbiology, José Alberto.

The information came on an informative report received by ANGOP on the fringe of the 8th International Congress of Physicians, happening in Luanda.

The specialist explained that although the real causes for that are not well determined yet, it considered that there is a great impact coming from cigarette smoking, alcohol consumption, viral infections and ionizing radiations, especially in the case of malignant tumours.

The specialist also advised people to go on regular consultations for early observation and diagnosis of tumours.
