This kills cancer cells, but can also impact normal cells leading to adverse side effects. Common chemotherapy side effects include; hair loss, mouth sores, loss of appetite, diarrhea, nausea and vomiting, premature menopause, infertility, and damage to the blood-forming cells within bone marrow.
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 promoters of about one third of the 167 miRNAs evaluated by Vrba et al. [35] in normal breast tissues were differentially hyper/hypo-methylated in breast cancers. A more recent study pointed out that the 167 miRNAs evaluated by Vrba et al. were only 10% of the miRNAs found expressed in breast tissues. [ 36 ]
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 ]

Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
[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 ...
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.
