Women Who Smoke Just 100 Cigarettes In Their Lifetime Are '30% More Likely To Get Breast Cancer

I have in the past heard that smoking may generally increase the chances of cancer but had no medical reference(I didn't research it anyway). As a result, I assumed it was just another hoax aimed at scaring people away from smoking.
However in a new report, the claim that smoking can increase the chances of cancer has been substantiated. In the report, research shows that smoking does increase the chances of breast cancer in women by 30%. Read the interesting report below:

Many social smokers believe they don't puff on enough cigarettes to be at risk of serious side effects.
But new research shows that smoking just 100 cigarettes in a lifetime increases a woman's chance of developing breast cancer by 30 per cent.
The research also revealed that women between 20 and 44 years old who have smoked a pack of cigarettes a day for at least 10 years are 60 per cent more likely to develop the most common form of breast cancer.
Dr Christopher Li, from the Fred Hutchinson Cancer Research Centre in Seattle, and his team analysed data from young women in the Greater Seattle area who were diagnosed with breast cancer between 2004 and 2010.
Of those women, 778 were diagnosed with the more common oestrogen receptor-positive type and 182 had the less common but more aggressive triple-negative type.
