The EGFR, which stimulates the cancer proliferation via PI3K/RAS signaling, the repair of DNA damage and metastasis [19,20,21,22,23], is overexpressed in various tumors, e.g., TNBC (52–54%) [24,25], lung cancer (40%) [26,27], glioblastoma (50%), head and neck cancer (80–90%) [24,25,28], ovarian, cervical, bladder, gastric, endometrial and colorectal cancers [29].
