New study reveals genetic explanation for cancer’s higher incidence in males than females
Researchers have found a genetic difference between men and women which they believe partially explains the higher incidence of cancerous tumours in men.
Researchers from the Dana-Farber Cancer Institute alongside those from Massachusetts General Hospital and the Broad Institute, found that women carry an extra copy of certain protective genes within their cells which acts as an additional line of defence against the cells growing out of control. The gene in question, KDM6A, is found on the X chromosome, women have two X chromosomes whereas men have one.
Under the theory being tested, male cells would need a harmful mutation in only one copy of an EXISTS gene for it to turn cancerous. In contrast, female cells would need harmful mutations in both copies of the gene. Through studying the genomes of more than 4,000 tumour samples researchers found support for this theory.

Sri Lanka to introduce a ban on the sale of individual cigarettes
Attending a meeting of the Government Medical Officers Association, the Sri Lankan Health Minister announced that the Government will shortly introduce new regulations to ban the sale of individual cigarettes.
Banning the sale of individual cigarettes, and small packs, is recommended by the WHO Framework Convention on Tobacco Control (FCTC) as it helps to discourage tobacco consumption, especially among young people and those on low incomes.

Australia: Tobacco companies pledge to obey law
Tobacco companies Philip Morris International and Zen Sensations have made legal undertakings to ensure their cigarettes fully comply with Australia’s mandatory Reduced Fire Risk safety standard, following recalls in 2015.
The Australian Competition and Consumer Commission has accepted court enforceable undertakings from both companies which included a voluntary $300,000 donation by Philip Morris to the New South Wales Rural Fire Service.
