  Cancer is one of the most feared diseases in the world it has increased
disturbingly and breast cancer occurs in one out of eight women, the prediction
of malignancies plays essential roles not only in revealing human genome, but
also in discovering effective prevention and treatment of cancers. Generally
cancer disease driven by somatic mutations in an individual DNA sequence, or
genome that accumulates during the lifetime of person. This paper is proposed a
novel method can predict the disease by mutations despite The presence in gene
sequence is not necessary it are malignant, so will be compare the protein of
patient with the gene's protein of disease if there is difference between these
two proteins then can say there is malignant mutations. This method will use
bioinformatics techniques like FASTA, CLUSTALW, etc which shows whether
malignant mutations or not, then training the backpropagation algorithm using
all expected malignant mutations for a certain genes (e.g. BRCA1 and BRCA2) of
disease, and using it to test whether patient is holder the disease or not.
Implementing this novel method as the first way to predict the disease based on
mutations in the sequence of the gene that causes the disease shows two
decisions are achieved successfully, the first diagnose whether the patient has
mutations of cancer or not using bioinformatics techniques the second
classifying these mutations are related to breast cancer (e.g. BRCA1 and BRCA2)
using backpropagation with mean square rate 0.0000001. Keywords-Gene sequence;
