Smoking-Risk Factor for Metastasis in Breast Cancer

Abstract

Breast cancer is one of the most frequent neoplasia in women. The discovery of metastasis risk factors can influence the evolution of the disease. Environmental factors, especially smoking, play a very important role in the evolution of many neoplasms. We evaluated the status of smokers of patients with metastases against the witness batch, patients with breast cancer without metastases. We compared the age arithmetical mean of patients who smoked to that of patients who did not smoke (p = 0, 00029) and we observed there is a significant difference between the age means of smokers and that of nonsmokers. Our study results suggest that smoking, represented as a risk factor, significantly influences the apparition of metastases (p = 0, 001044). Systemic effects of smoking may play a role in influencing the course of breast cancer and other cancers.
