Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells. Ignoring the body's signal to stop, malignant cells multiply to form tumors in organs and tissues or, in the case of blood cancers, crowd out normal cells in the blood stream and bone marrow. In a healthy body, cells grow and divide in a controlled, orderly fashion to replace those that have grown old or have been damaged and die by design in a process called apoptosis. Cancer occurs when these natural processes go awry. When the genetic material of a cell – the DNA – is damaged, mutations can arise, potentially disrupting normal growth and division. An accumulation of mutations can turn normal cells into precancerous cells, which sometimes multiply and evolve into cancer cells. Cancer is a result of the accumulation of these cells. Cancer is not an event, but a process that takes time, often years, to develop. The length...

A study has revealed that anxiety and depression are very common among thyroid disorder patients in the country. Research conducted by Binu Gorkhali, a lecturer at Nepal Institute of Health Sciences, and her team, revealed this. They had conducted the research on 129 thyroid disorder patients at Tribhuvan University Teaching Hospital. All the patients were above 20 years of age. Depression was prevalent in 42.6 per cent patients whereas, anxiety was prevalent in 50.4 per cent patients. From among the patients, depression prevalence was significantly high in females. Around 47.1 per cent of women were found to be suffering from depression while only 25.9 per cent male patients suffered depression. Various diseases can affect mental health of people. “There is a co-relation between thyroid, anxiety and depression. People are likely to suffer from anxiety and depression when they suffer from thyroid disorder as hormones released from thyroid gland regulates central and periphe...
