Before revision:  With regard to this 4 \% quantile of genes, pairs of localizations share between 314 and 1889 genescharacterizing the tumor state. The gene expression landscape shows distances between pairs of tumor localizations which inversely correlate with the number of shared genes. The most significantly altered top pathway in the cancer state is related to the "Extracellular URLanization" .
After revision:  With regard to this 4 \% quantile of genes, pairs of localizations share between 314 and 1889 genescharacterizing the tumor region is a kind of attractor. Tumors in advanced stages converge to this region independently of patient age or genetic variability. 5) There is a landscape of cancer in gene expression space with an approximate border separating normal tissues from tumors .
