Xiong Dun (熊頓) (19 October 1982 — 16 November 2012) was the pen-name of Xiang Yao (項瑤), a Chinese cartoonist, who documented her own experience with Non-Hodgkin lymphoma in her web comic Go to the Devil, Mr. Tumor.

[1] Xiang Yao worked as an illustrator for Beijing advertising company, while creating comics using the name Xiong Dun,[2] with titles like A Bachelorette's Diary, Superwoman on Diet, Stories in City,[3] and Maturing into Womanhood.

She blamed her own long hours for her turn of health, saying "I hope my illness will sound alarm bells to those workaholics like me.

"[6] Despite the grim subject, the cartoon published in book form as Go to the Devil, Mr. Tumor (2013)[7] was upbeat in tone,[citation needed] with humorous illustrations and observations about her cancer and treatments.

"[8] A film based on her life and work, Go Away Mr. Tumor, directed by Han Yan and starring Bai Baihe and Daniel Wu, was released in China in 2015,[9] and was considered a box-office success.
