Breast cancer is said to be the commonest type of cancer afflicting women in both developed and developing countries.
According to the World Health Organisation, its frequency in developing world is on the rise, contrary to the belief that it is a disease of the developed world. For instance, the WHO said almost 50 per cent of cases and 58 per cent of deaths from breast cancer occur in developing countries.
Scientists say that cancer can strike almost any part of the body. Researchers have also said that cancerous cells were normal cells before undergoing some changes which made them cancerous.
