ABSTRACT
Malignant neoplasms are a leading cause of morbidity and mortality in middle-aged people or the elderly. Solid tumours are most common in the lung, breast, colon, cervix, stomach, pancreas, ovary and prostate in adults and most are carcinomas. Tobacco is at least partly responsible for many of these malignant neoplasms. Younger people may be affected by haematological malignancies and occasionally rare tumours. The prognosis of much malignant disease is poor and treatment can have significant adverse effects; thus, prevention and early detection of lesions is important.
