Research has stated that chances of developing types of cancer increase if someone in the family is suffering from cancer.

A study was conducted by researchers on 23,000 people in Italy and Switzerland and it was seen that for each of 13 cancers, there was increased risk of developing same disease among close relative. Cancer depends on a large extent on genes, lifestyle and environment.

The research followed 12000 people who had cancers of various body parts. All these patients were then compared to 11000 people who were without cancer.

Family history's information was then collected by researchers from relatives who were first-degree relatives like child, sibling or parents.

It was seen that the risk of developing pharyngeal cancer and cancer of larynx was triple among first-degree relatives of people who suffered from cancer of larynx.

Study leader Dr Eva Negri, of the Mario Negri Institute for Pharmacological Research in Milan, Italy, said, "If you have a relative with one type of cancer your risk of the same type of cancer is increased. What this study has highlighted is that sometimes if you have a relative with one cancer your risk of another cancer can be increased."
