Returning to the impact of Boveri’s book, the verdict on the SMT is now fairly clear.Despite the spectacular technological advances in the fields of genetics, and in cell and molecular biology, (i) the SMT has been aggressively explored but, so far, not tested experimentally [5]; (ii) the SMT-inspired collected evidence tends to rule out the notion that cancer is a disease; and (iii) the success of therapies based on the SMT, are acknowledged, even by their supporters, to be meager to non-existing [9].In truth, this concept was originally stated by German pathologists in the 1880s.

Be that as it may, Boveri’s original speculation (“I am convinced that every theory of malignant tumors is wrong which does not take into account its unicellular origin.” page 40) remains the central tenet of the current version of the SMT [8].

Most of Boveri’s current followers consider that mutations in the cell cycle components affect the speed at which the original tumor cell and its descendants proliferate; however, there is no experimental evidence supporting the generality of that claim [8].

The study of the organism was then guided by what today is called an organicist perspective, whereby no body part could be understood but in relation to the other parts and the whole itself [2].

The birth of experimental embryology (1890s), the rediscovery of Mendel’s experiments (ca. 1911, if one accepts Morgan’s conversion as the starting point) and of cell culture (1907–1912) ushered in a more reductionist view in biology, culminating with Boveri’s claim that embryology will become a biochemical science [1].

Meanwhile, some biologists objected to Boveri’s claim about the centrality of the “cancer cell” in carcinogenesis. Indeed, the spectacular explosion of powerful molecular biology techniques made possible the accurate tracking of thousands of somatic mutations in cells from tumors, now known also to be present in normal cells of normal hosts.

In the 1930s, for instance, Conrad Waddington revived the notion that cancer was instead a disease of development, consistently presenting a concept that was compatible with the assumption that this was a disease; later, J. This latter, unexpected, finding complicates even more the search for those still elusive cancer “driver” mutations [7].

For instance, using diverse experimental models, researchers have shown that mutated somatic cells (including carriers of chromosomal aberrations) belonging to cancers can be “normalized” [5].

This compelling evidence against the SMT is either ignored, or else incorporated as “add-ons” to the SMT in which the microenvironment also plays a role in carcinogenesis – albeit always subservient to mutations [8].

In the Introduction of his book, Boveri expressed his misgivings about proposing his theory on carcinogenesis, given the cold reception he sensed when he first exposed it among his colleagues.

The first English translation only appeared in 1929 (by Boveri’s wife, Marcella).
