Smoking greatly increases the risk of certain cancers of the immune system and bone marrow, research has found.
A study, published in the British Journal of Cancer, found that the risks of Hodgkin's lymphoma and some bone barrow cancers were doubled in women who smoked around 20 cigarettes each day.
Furthermore, the risks of other forms of blood cancer also spiked among smokers, but to a lesser extent.
Over a ten year study of 1.3 million middle-aged women, 9,000 women developed leukaemia, which is a cancer of the bone marrow of the immune system.
By the time the decade was up, six in every 1,000 non-smokers developed one of these cancers, compared to almost eight in every 1,000 for smokers.
Professor Valerie Beral, one of the study authors, said: “These results highlight yet again how important smoking is as a cause of cancer.
“Smoking raises the risk of many types of cancer, not just lung cancer, and also the risk of heart attack and stroke, which many people may not be aware of.”
