Olivia Newton-John has set out for the 228-kilometre trek along the Great Wall of China. This has led to an eclectic bunch of Australian and international celebrities to help raise money for charity.

It’s heartwarming to see a stellar cast of celebs take part in raising funds for cancer patients of all types. I just found out that mesothelioma is also a type of cancer.

Cancer is a leading cause of death worldwide. From a total of 58 million deaths worldwide in 2005, cancer accounts for 7.6 million (or 13%) of all deaths. The main types of cancer leading to overall cancer mortality are:

* lung (1.3 million deaths/year);
* Stomach (almost 1 million deaths/year);
* Liver (662,000 deaths/year);
* Colon (655,000 deaths/year) and
* Breast (502,000 deaths/year).
