The analysis of 11 various oncogenes expression in different human tumors showed that each tumor is characterised by a specific functioning program of these genes. In 40-50% of tumors the oncogenes ras, fos and myc are expressed. All other oncogenes are either considered to be "silent" or are expressed only in few cases. The increased expression of sis and myb oncogenes is observed in metastases.
