The first cause of cancer was identified by British surgeon Percivall Pott, who discovered in 1775 that cancer of the scrotum was a common disease among chimney sweeps. [ citation needed ] The work of other individual physicians led to various insights, but when physicians started working together they could draw firmer conclusions.
Cancer cells often opportunistically switch between different kinds of motion. Some cancer researchers hope to find treatments that can stop or at least slow down the spread of cancer by somehow blocking some necessary step in one or more kinds of motion. [16] [17] All steps of the metastatic cascade involve a number of physical processes.
This step is important in the metastatic journey as it enables tumor cells to leave their original site and circulate through the body. pro- angiogenic factors like VEGF, [21] along with interactions between cancer calls and the vessel walls, make it easier for tumor cells to penetrate into the bloodstream or lymphatic system. By gaining access ...
A newly identified colon cancer gene may drive the disease by making the environment in the vicinity of tumors more hospitable to them, researchers say. Why does colon cancer grow so fast? Study ...
Cancer cells have unique features that make them "immortal" according to some researchers. The enzyme telomerase is used to extend the cancer cell's life span. While the telomeres of most cells shorten after each division, eventually causing the cell to die, telomerase extends the cell's telomeres. This is a major reason that cancer cells can ...
Scientists suggest the findings could one day allow doctors to use a blood test to predict how a patient’s cancer may progress. Genetic clues reveal how cancer might grow and spread – study ...
The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
The therapy, which uses a device, slowed the spread of cancer in the brain to 21.9 months, along with supportive care, compared to 11.3 months for supportive care alone in patients with non-small ...
