According to the new edition of the World Cancer Report from the International Agency for Research on Cancer, due to rapid increase in cancer cases, cancer will soon replace heart disease as the leading cause of deaths worldwide.

Recent research has shown that presence of a specific gene can be linked to urge to eat high-calorie foods. Researchers found that children with a common variation of the gene ate 100 extra calories per meal.

A recent research has shown connection between gene mutation and the most common eye cancer. Research team led by Catherine Van Raamsdonk, an assistant professor of medical genetics at the University of British Columbia has discovered a genetic mutation in a gene called GNAQ that could be responsible for up to 45 per cent cases of uveal melanoma.

Uveal melanoma is caused by unregulated growth of melanocytes which are also found in the skin and are cells linked to a life-threatening form of skin cancer. Researchers found that GNAQ regulates melanocyte survival.  

Recent research has shown connection between fertility drugs and increased risk of womb cancer in women. A research team led by Dr Ronit Calderon-Margalit at Hadassah-Hebrew University in Jerusalem studied the effects of these drugs by comparing cancer incidence in 15,000 Israeli women 30 years after they gave birth.

Neither falls nor avalanches cause as many deaths on Mount Everest as brain swelling. A study conducted by  Massachusetts General Hospital, University of Toronto and three British hospitals have revealed that brain swelling occurs at high altitude especially when the climbers are descending. 212 deaths of climbers were analysed before coming to the given conclusions:

- There are 1.1 deaths for every 100 climbing attempts by Sherpas or Tibetans

- 1.6 climbers die for every 100 non-Himalayan mountaineers
