Air pollution may impact foetal cardiovascular system, says study

Know how air pollution affects your heart

Major Indian metropolitan cities are reeling under the effects of severe air pollution, euphemistically called ‘smog’, this phenomenon occurs every year during winter. This has deleterious effects not only on the respiratory system, but as recent studies show, also on the cardiovascular health of people living in urban areas. Excessive air pollution is associated not […]

Welding fumes raise lung cancer risk, reveal researchers

A new study suggests this holds true regardless of other risk factors like smoking or exposure to asbestos. “Welding fumes have previously been classified as ‘possibly carcinogenic’ to people,” said Dr Denitza Blagev, a researcher at the University of Utah and Intermountain Medical Center in Murray, Utah. “Although welders have been observed to experience higher […]

Prolonged hoarseness of voice can be a sign of lung cancer

A sudden hoarse voice could mean many different things, but if combined with other symptoms of lung cancer, you should see your general physician. This is especially important if hoarseness has lasted three weeks or more. The main symptoms of lung cancer include a cough that doesn’t go away after two or three weeks or […]

E-cigarette users show cancer-linked genetic changes, reveals new study

A USC study in 93 people shows that e-cigarette users develop some of the same cancer-related molecular changes in oral tissue as cigarette smokers, adding to the growing concern that e-cigarettes aren’t a harmless alternative to smoking. The research, published this week in the International Journal of Molecular Sciences, comes amid a mushrooming e-cigarette market […]

#WorldCancerDay: Missed cancer screenings tied to earlier death from other causes

Researchers think skipping screenings may be a marker for more generally neglecting one’s own health. “It was not a direct effect of missing the cancer screening that led to the increased mortality in the non-compliers,” said study co-author Dr Paul Pinsky of the National Cancer Institute in Bethesda, Maryland. “Rather, we believe that non-compliance with […]

Certain blood pressure drugs linked to increased risk of lung cancer

Use of angiotensin converting enzyme inhibitor drugs (ACEIs) to lower blood pressure is associated with an increased risk of lung cancer compared with use of another group of blood pressure drugs called angiotensin receptor blockers (ARBs), finds a study in The BMJ today. The risk is particularly elevated among people using ACEIs for more than […]

New cancer drug attacks cancer-causing gene linked to obesity

Researchers from Michigan State University are using novel molecular routes to attack cancer. The scientists were particularly interested in bromodomain inhibitors (BET inhibitors). These are a promising new class of drugs that target the genes involved in cancer’s growth. BET inhibitors prevent the expression of certain growth-promoting genes and therefore slow tumour growth. The researchers […]
