In your hands is preventing breast cancer, do it now, then it may be late.
The new analysis looked at two large groups of data, which included about 400,000 women.
Previous studies have asked women about their type of sleep: if they preferred morning or night, how long they slept and if they had insomnia or not.
But these researchers monitored the data to take into account other factors that may affect the risk of breast cancer, such as obesity, family history of breast cancer, alcohol consumption and smoking.RELATED
Women who said they preferred mornings were slightly less likely to develop breast cancer. The researchers noted that early risers had roughly one less case of breast cancer per 100 women, compared to night owls.
Previous studies have suggested that night work shifts increase people's risk of developing cancer, and part of the blame is due to the lack of exposure to sunlight. This occurs, it is believed, for lack of melatonin, a hormone that is believed to be related to protection against breast cancer.
10 facts about cancer
About 16% of people die as a result of cancer. In 2015, 8.8 million people died, almost one in six dead in the world.
More than 70% of those killed by cancer occur in middle- or low-income countries.
The five types of cancer that in 2015 caused the highest number of deaths in men worldwide were lung, liver, stomach, colorectal and prostate.
The five most frequent types of cancer that caused the highest number of deaths in women were, in order of frequency, breast, lung, colorectal, cervical and stomach.
Not smoking tobacco can help prevent cancer. Between 30% and 50% of cancers can be avoided. Smoking, which causes approximately 22% of all cancer deaths, is the leading preventable cause of cancer in the world.
The vaccine protects against cancer-causing infections. In 2012, 25% of new cases diagnosed in middle- and low-income countries were due to cancer-causing infections. Human papillomaviruses produce cervical cancer and hepatitis B virus, liver cancer. Vaccination against these viruses could prevent 1.1 million cases of cancer each year.
In low-income countries, few patients have access to cancer treatment.
In 2015, less than 30% of low-income countries have reported that they offer cancer patients treatment, while in high-income countries this percentage is greater than 90%.
Cancer represents a considerable burden on the world economy. The economic impact of cancer is significant and continues to grow. It has been estimated that the total economic cost of cancer in 2010 was approximately $ 1.16 billion.
