Most cancers caused by "bad luck" in cell division and "poor repair" of the defect
Researchers at Johns Hopkins University studied 31 different cancers. Of those, just 9 were found to be linked to bad genetics or unhealthy lifestyle choices. However, researchers excluded two of the most common cancers from their study, breast cancer and prostate cancer (published in the journal Science). The most common cause of the production of most cancerous cells occurs when one chemical letter in DNA is incorrectly swapped for another during stem cell division. Scientists found that cancer rates were higher in parts of the body where cells are quickest to regenerate, thereby creating more random mutations. Genetic mutations that randomly crop up as our stem cells divide are “the major contributors to cancer overall, often more important than either hereditary or external environmental factors.” BBC: New research suggests most types of cancer are the result of bad luck, rather than unhealthy lifestyles, diet or even inherited genes. References: Study concludes that many cancers c...

Myelodysplastic Syndromes / Myeloproliferative Disorders
What are myelodysplastic syndromes? Myelodysplastic syndromes are clonal marrow stem-cell disorders, characterized by ineffective hemopoiesis leading to blood cytopenias, and by progression to acute myeloid leukemia in a third of patients. Who is affected? 15% of cases occur after chemotherapy or radiotherapy for a previous cancer. The syndromes are most common in elderly people. What is the cause? The pathophysiology involves cytogenetic changes with or without gene mutations and widespread gene hypermethylation at advanced stages. What are the symptoms? Clinical manifestations result from cytopenias (anemia, infection, and bleeding). How to make the diagnosis? Diagnosis is based on examination of blood and bone marrow showing blood cytopenias and hypercellular marrow with dysplasia, with or without excess of blasts. Prognosis depends largely on the marrow blast percentage, number and extent of cytopenias, and cytogenetic abnormalities. What is the treatment? Treatment of patients wit...
