The inheritance of epigenetic marks in the immediate generation is referred to as intergenerational inheritance. [3] In male mice, the epigenetic signal is maintained through the F1 generation. [4] In female mice, the epigenetic signal is maintained through the F2 generation as a result of the exposure of the germline in the womb. [4]
The next step in cancer immunoediting is the equilibrium phase, during which tumor cells that have escaped the elimination phase and have a non-immunogenic phenotype are selected for growth. Lymphocytes and IFN-gamma exert a selection pressure on tumor cells which are genetically unstable and rapidly mutating.
Cancer treatment drugs pose a strong selective force on all types of cells in tumors, including cancer stem cells, which would be forced to evolve resistance to the treatment. Cancer stem cells do not always have to have the highest resistance among the cells in the tumor to survive chemotherapy and re-emerge afterwards.

Oncogenomics is a sub-field of genomics that characterizes cancer-associated genes.It focuses on genomic, epigenomic and transcript alterations in cancer. Cancer is a genetic disease caused by accumulation of DNA mutations and epigenetic alterations leading to unrestrained cell proliferation and neoplasm formation.
One new study used a blood test to determine which colon cancer patients could skip chemotherapy after surgery. After surgery, some cancer patients can safely skip radiation or chemotherapy ...
One may then define the generation time as the time it takes for the population to increase by a factor of . For example, in microbiology , a population of cells undergoing exponential growth by mitosis replaces each cell by two daughter cells, so that R 0 = 2 {\displaystyle \textstyle R_{0}=2} and T {\displaystyle T} is the population doubling ...
Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". [1] In oncology, PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically. Similarly ...
