|Cancer risk depends on genes, lifestyles and environment|
By Helen Briggs
Having cancer in the family can increase your chances of developing not only the same cancer but other types too, research suggests.
A study of 23,000 people in Italy and Switzerland found that for each of 13 cancers, close relatives had an increased risk of the same disease.
But there was also evidence that a family history of one cancer could significantly raise the risk of others.
Cancer charities say risk depends on genes, lifestyle and environment.
The research, published in the journal Annals of Oncology, followed 12,000 patients with cancer at different sites in the body.
They were compared with 11,000 people without cancer.
The researchers collected information on family history of cancer, particularly in a first-degree relative (those who share about 50% of their genes - namely a parent, sibling or child).
