ISLAMABAD:Scientists have discovered why patients undergoing chemotherapy are likely to suffer from Deep Vein Thrombosis (DVT) — a blood clot that can detach from a vein and travel to the lungs fatally causing a pulmonary embolism. A team of researchers from New Zealand, found in their study on chemotherapy patients that the chemotherapy – which remains the most common treatment for all cancers – stimulates release of tiny bubbles from the surface of cancerous tissue, causing blood clots to form in neighboring blood vessels. This prevents the rest of the bodily organs to be deprived of oxygen – a phenomenon known as hypoxia. The link between cancer and thrombosis was noted over 100 years ago, but the reasons for the association have remained unclear, Associate Professor Alex McLellan informed to the press. “We now have insight into how these bubbles from dying cancer cells may cause thrombosis during chemotherapy.
