Cancer Research:Metabolic reprogramming restrains senescent cells from becoming cancerous ♦ synchrotron makes tumors visible ♦ Pancreatic cancer risk linked to weak sunlight:

Protein 'brake' in metabolic reprogramming restrains senescent cells from becoming cancerous Research has shown that cancerous cells have a different metabolism -- essential chemical and nutritional changes needed for supporting the unlimited growth observed in cancer Now, scientists have identified a way that cells can reprogram their metabolism to overcome a tumor-suppressing mechanism known as senescence, solidifying the notion that altered metabolism is a hallmark of cancer progression.
Compact synchrotron makes tumors visible Soft tissue disorders like tumors are very difficult to recognize using normal X-ray machines, as there is hardly any distinction between healthy tissue and tumors. Researchers have now developed a technology using a compact synchrotron source that measures not only X-ray absorption, but also phase shifts and scattering. Tissue that is hardly recognizable using traditional X-ray machines is now visible.
Pre-existing inflammation may promote the spread of cancer Allergic reactions -- or at least the pre-existing inflammation from these reactions -- may set the stage for cancer to spread from one area to another.
Pancreatic cancer risk linked to weak sunlight: Harm may come from low vitamin D Pancreatic cancer rates are highest in countries with the least amount of sunlight. Low sunlight levels in those countries were due to a combination of heavy cloud cover and high latitude

Scientists identify key receptors behind development of acute myeloid leukemia Scientists have discovered that a certain class of receptors that inhibit immune response are crucial for the development of acute myeloid leukemia (AML), the most common acute leukemia affecting adults
