Many risk factors may increase your chance of developing breast cancer, but it is not yet known exactly how some of these risk factors cause cells to become cancerous. Hormones seem to play a role in many cases of breast cancer, but just how this happens is not fully understood. Certain changes in DNA can cause normal breast cells to become cancerous. DNA is the chemical in each of our cells that makes up our genes — the instructions for how our cells function.
Researchers have identified things that can increase your risk of breast cancer. But it’s not clear why some people who have no risk factors develop cancer, yet other people with risk factors never do. It’s likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment.
Here are some list of people who has risk of getting breast cancer:
Simply being a woman is the main risk factor for developing breast cancer. It’s because women’s breast cells are constantly exposed to the growth-promoting effect of the female hormones estrogen and progesterone.
Your risk of breast cancer increases as you age. Women older than 55 have a greater risk than do younger women.
Certain gene mutations that increase the risk of breast cancer can be passed from parents to children.
4. Family history
If there’s someone in your family get this disease, you may have a chance of being diagnosed with breast cancer as well.
Women who have had no children or who had their first child after age 30 have a slightly higher breast cancer risk. Having many pregnancies and becoming pregnant at a young age reduce breast cancer risk. Pregnancy reduces a woman’s total number of lifetime menstrual cycles, which may be the reason for this effect.
Being overweight or obese has been found to increase breast cancer risk, especially for women after menopause. Women who are overweight tend to have higher blood insulin levels which have also been linked to some cancers, including breast cancer.
The use of alcohol is clearly linked to an increased risk of developing breast cancer. Studies found that alcohol can increase the cancer cells.
