The earliest known descriptions of cancer appear in several papyri from ancient Egypt. The Edwin Smith Papyrus was written around 1600 BC (possibly a fragmentary copy of a text from 2500 BC) and contains a description of cancer, as well as a procedure to remove breast tumours by cauterization, stating that the disease has no treatment.

Embryonic stem cells and germ cells have also been described as immortal. [8] [9] Immortal cell lines of cancer cells can be created by induction of oncogenes or loss of tumor suppressor genes. One way to induce immortality is through viral-mediated induction of the large T-antigen, [10] commonly introduced through simian virus 40 (SV-40). [11]

Some alternative treatments have been investigated and shown to be ineffective but still continue to be marketed and promoted. Cancer researcher Andrew J. Vickers stated, "The label 'unproven' is inappropriate for such therapies; it is time to assert that many alternative cancer therapies have been 'disproven'." [200]

HeLa cells have also been used to define cancer markers in RNA, and have been used to establish an RNAi Based Identification System and Interference of Specific Cancer Cells. [ 44 ] In 2014, HeLa cells were shown to provide a viable cell line for tumor xenografts in C57BL/6 nude mice, [ 45 ] and were subsequently used to examine the in vivo ...
