"Neo-cancer theory: triumph over the conventional cancer theories" was published by the author in 2021 by the "LAMBERT Academic Publishing". In conventional oncological theories, there is many weakness, many limitations. These theories are quite unable to answer so many questions regarding cancer. The "Neo-cancer theory" is a modified cancer theory which has the potential to answer these questions in a very satisfactory way. The most crucial demarcation between the theme of conventional cancer theories and the "Neo-cancer theory" is that in conventional theories cancer is considered as a local disease with systemic manifestations, whereas, in the "Neo-cancer theory" cancer is considered as a systemic disease with local manifestation. Therefore, the basic concept, clinical aspects, investigations, treatment and the oncological associations of the "Neo-cancer theory" is quite different from the conventional onco-theories. In this text, I am going to explain this theory in breast cancer patients. A very rich atlas of breast cancer patients is represented in this text with case discussion.
