Grade 3 tumor was diagnosed in 31.8% patients. Stage 3 and metastasic stage were found respectively in 44.9 % and 22.6% of screened women. 40.4% of cancer patients with satisfactory immunohistochemical data were triple negative breast cancer (TNBC) but no significant variation was found in these features between TNBC and non TNBC groups. A 3‐year survival rate of 63% was observed.ConclusionsThese results support the already published studies on the likely genetic basis of breast cancer in our population.
