Smoking and Cancer

The role of smoking, socio-economy and sex in explaining inequalities in cancer incidence and mortality.

This project will provide more insights into the association between smoking and cancer from a socio-ecomomic and sex perspective, as well as more knowledge about sex specific cancers. Our results may be used in targeted preventive efforts locally as well as globally.

Main objective

To prospectively examine to what extent smoking is a preventable cause of different types of cancer and death

Specific Aims

Outcomes with smoking as exposure - currently being studied/under planning provided continued funding

1. Colon and Rectal cancer
2. Breast Cancer
3. Epithelial Ovarian Cancer
4. Lung Cancer
5. Total and cause specific mortality
6. Pancreatic Cancer 


Aspects of Lung Cancer by Sex

Is it time to establish breast cancer as a smoking-related cancer?

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.


The Increased Risk of Colon Cancer Due to Cigarette Smoking May Be Greater in Women than Men

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.


Female smokers have a higher colon cancer risk

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.
