Washington, Feb 20 : The quality of air inside an asthmatic child's bedroom can have an adverse impact on his health, according to a new study.

Johns Hopkins University researchers have found a significant association between increasing levels of indoor particulate matter pollution and the severity of asthma symptoms among children.

Particulate matter is an airborne mixture of solid particles and liquid droplets. The solid particles come in numerous shapes and sizes and may be composed of different chemical components.

These particles enter the respiratory system and can be produced indoors through activities such as cooking and dusting.

A group of UK health professionals believe that women going for screening for breast cancer are not provided the right information. Some women are given medical treatment which is not required.

The team comprising of Professor Michael Baum, Emeritus Professor of Surgery at University College London and Dr Paul Pharoah, Cancer Research UK Senior Clinical Research Fellow, University of Cambridge and others said that there are harms associated with early detection of breast cancer by screening that are not widely acknowledged.
