Breast Cancer and Alcohol

For years, alcohol is known to be a risk factor for breast cancer. An estimate suggests that among the women who drink two units of alcohol daily have eight percent higher risk of developing breast cancer than those who drink lesser.

According to a research conducted on 1,280,000 women, every additional drink regularly taken every day increases the occurrence of breast cancer by 11 per 1000. Sadly, there are about 6 percent of breast cancer cases that could have been prevented if the women reduce alcohol consumption to a very low level. The statistics also reveal that sixty percent of alcohol related cancers among women are breast cancers.

How does alcohol harm?
Cancer caused by binge drinking can be because the alcohol causes:
  • Increased damage to DNA
  • Enhances metastatic chances of breast cancer cells
  • Elevated androgen and estrogen levels
  • An increased susceptibility of the mammary glands to carcinogens
The severity of the breast cancer depends upon the amount of alcohol intake.

Additional factors
Alcohol-attributed breast cancer is worsened by poor dietary habits with iron deficiency, lifestyle, hormone replacement therapy and some biological characteristics such as hormone receptor expression in the cells of tumor. In the women affected by breast cancer, even a little alcohol drinking every day increases the volume of the breast tumors.

Genetic risks
Many studies suggest that the female babies of the drunk mothers are at an increased risk of developing breast cancer later in their lives, especially if a woman is in a habit of binge drinking during pregnancy. During pregnancy, consuming alcohol even in a small amount can increase estradiol level by reducing melatonin or other mechanism.

The breast cancer can reoccur in drunk women, once they have fully got rid of this disease by proper treatment.
