Women who smoke or have smoked about a packet of tobacco a day for 10 years or more have a higher risk of developing the most common type of breast cancer. This is the decisive conclusion of the latest study from the Fred Hutchinson Cancer Research Center in Seattle and published in the journal Cancer .
The study investigated the relationship between smoking and breast cancer among young women and concluded that smoking is directly linked to an increased risk of breast cancer.
To do this, they conducted a study based on 778 patients with hormone receptor-positive breast cancer (the most common of breast cancers) and 182 patients with triple-negative breast cancer (less common but more aggressive).
The patients were between 20 and 44 years old and were diagnosed between 2004 and 2010.
The researchers determined that young women who were current or recent smokers and had smoked a packet of tobacco a day for at least 10 years had a 60% aggravated risk of being affected by the most common breast cancer .
