               on viability of MDA-MB-361 (ER /Her-2 ) breast cancer cells was measured as described in the “METHODS”. All significant differences
               between control and treated cells are indicated by “*” and are reported at P < 0.05
               The effect of ethanol extract from leaves and seeds is shown in Figure 7C. The data indicate that none of the
               papaya fractions also has any significant effect on cell viability of MDA-MB-361 breast cancer cells.
