Breast Cancer Awareness Month: These Things May Be Silently Increasing Your Risk
Weight Gain: Research suggests that overweight and obese women are more prone to developing breast cancer as opposed to their counterparts. This risk augments two-fold after menopause since more fat corresponds to more estrogen in the body. Overweight individuals also tend to have slightly higher blood insulin levels, which have been observed to increase the risk of breast cancer. While this relationship is quite complex to understand, a study published in the journal BMJ Open, noted that women who went a skirt size up every decade between their 20s and 60s, increased their risk by 33 percent. 
Contraceptive Pills: A chock full of estrogen, your birth control pills may be putting you at an increased risk of breast cancer. While they may be protecting you from unwanted and unplanned pregnancies, high doses of the hormone in your blood can overstimulate your breast cells compounding your breast cancer risk. A recent study published in the journal Cancer Research, found this association to be true and valid. 
Alcohol: Research has backed this connection time and again, providing valid data on how excessive consumption of alcohol can take you closer to damaging your breast health. The American Cancer Society denotes that those women who have 2 to 5 drinks daily have about 1½ times the risk of women who don’t drink alcohol.
Eating Too Late: While your diet can contribute a major chunk to your increased breast cancer risk, the time that you eat also donates equally to the peril. How? According to a recent study published in the journal Cancer Epidemiology, Biomarkers & Prevention, a late night snack can become detrimental to your breast health.  Dining late in the night can conflict with your insulin levels and hamper the efficient utilization of glucose, which has been shown to increase the risk of breast cancer.
Late Night Work: Yes, working very late in the night may be secretly working up to form cancerous lumps in your breast. Not only does late night work mess up with your circadian rhythm wreaking havoc on your hormones and health, it can also amplify your risk for developing breast cancer. While this is a fairly recent finding and more studies are need to back this claim, a study published in the journal Occupational and Environmental Medicine found women who worked night shifts were up to four times more likely to develop breast cancer than those who didn’t. 
Yes, you are a woman and that is your biggest risk for developing breast cancer, notes The American Cancer Society. While this fact is inarguable, the society also points out that the diagnosis of breast cancer in women has gone up due to improved detection methods accompanied by increased awareness. However, the rise in new breast cancer cases is still prevalent.
There are several factors which increase your susceptibility to breast cancer—genes, hormones, age, and unhealthy lifestyle habits among others. However, there are also simple daily habits which can result in a positive breast mammogram.
To observe Breast Cancer Awareness Month this October, we tell you about five such things which might be unknowingly putting you at a risk.
