Cancer subtypes linked to smoking, alcohol
Three subtypes of oesophageal and stomach cancers have been found to be linked to smoking, it has emerged.
Further results from the study, conducted by the American Association for Cancer Research (AACR), showed that an additional subtype is caused by alcohol use.
The wide-scale research involved more than 120,000 subjects in the Netherlands and confirmed previous risk factors associated with these forms of cancer.
However, attendees at the seventh annual international conference on frontiers in cancer prevention research, were told that the results did not explain why there is a rising number of cases involving these types of tumours.
"The results of this study again confirm recommendations for a healthy lifestyle, namely not to smoke and to drink alcohol in moderation," said study author, Jessie Steevens, of the department of epidemiology at Maastricht University.
He went on to state that other risk factors could include obesity, diet, exercise and occupational exposures.
Such news may be of interest to those who are currently considering making arrangements for family health insurance.
In other recent announcements, the AACR has also shown that lifestyle factors such as not smoking or taking regular exercise can have a significant impact on the types of health care insurance that are made available to older people.
