DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that certain groups of genes have a tendency to co-express.

Normal cells typically generate only about 30% of energy from glycolysis, [118] whereas most cancers rely on glycolysis for energy production (Warburg effect). [ 119 ] [ 120 ] But a minority of cancer types rely on oxidative phosphorylation as the primary energy source, including lymphoma , leukemia , and endometrial cancer . [ 121 ]

The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
The cervix (pl.: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. [1] The human female cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago.
Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop. [1] Postpartum physiological changes may be different for women delivering by cesarean section . [ 2 ]
[25] [26] The research available is limited with regard to the cervix and therefore is limited in discerning what is or is not normal. [12] Four different pathways have been identified that can result in preterm birth and have considerable evidence: precocious fetal endocrine activation, uterine overdistension ( placental abruption ), decidual ...
