Smoking was established as a cause of lung cancer in the late 1950s. It then took another 50 years to establish that colorectal cancer was also a smoking-related cancer. However, as of 2018, a causal relationship between smoking and breast cancer had not yet been established. It may seem strange that it is taking so long to prove that smoking is a cause of all three of the most common cancers globally. Breast and lung cancer each account for 2.09 million cases annually and colorectal cancer for 1.8 million.
Smoking is a recently established risk factor for colon cancer. The authors wanted to explore the hypothesis that women may be more susceptible to smoking–attributed colon cancer than men as one of the possible explanations for the high colon cancer risk of Norwegian women. Female smokers may be more susceptible to colon cancer and especially to proximal colon cancer than male smokers.
Most people understand the link between smoking and lung cancer, but researchers are learning even casual smokers are increasing their risk for other cancer types as well. Case in point: Smoking increases the risk for developing colorectal cancer, and female smokers may have a greater risk than male smokers, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Most of us are well-aware of many of the ill health effects of smoking, particularly in the form of respiratory conditions like lung cancer and emphysema. However, a recent study has found that smoking can elevate the risk of colorectal cancer as well. What's more, women - even those who smoke less cigarettes and less often than men - are more likely to develop colorectal cancer than men are.
Women who smoke seem to be more likely to develop bowel cancer than male smokers, a study has found. Norwegian researchers looked at data on more than 600,000 men and women who were followed up for an average of 14 years.
Women who are former or current smokers are at an increased risk of developing ovarian cancer, according to one of the first studies to show such an association. Inger T. Gram, MD, PhD, professor, Department of Preventive Medicine, University of Tromsø, presented the findings here on the Annual Meeting of the American Association for Cancer Research (2006).
