In an exceptional case, scientists have documented a person who has survived 12 tumours, at least five of them malignant, and all aggressive cancers that disappeared relatively easily -- opening up new avenues for early diagnosis and immunotherapy in cancer. 

Featured in the study published in the journal Science Advances, the person (whose name has been withheld) first developed a tumour when almost still a baby, followed by others every few years.

In less than 40 years of life, the individual developed 12 tumours, at least five of them malignant, and each with a different type and in a different part of the body.
