Introduction
Breast cancer is one of the most common cancers among women, and it is important to be aware of the risk factors associated with it. While some risk factors, such as age and family history, are out of our control, there are certain lifestyle choices that can increase our risk of developing breast cancer. In this article, we will discuss 8 things that can put you at a higher risk for breast cancer, and what you can do to reduce your risk. We will also provide tips on how to make healthier food choices to help reduce your risk.
8 Things Putting You at “High Risk” for Breast Cancer
Breast cancer is one of the most common forms of cancer in women, and it’s important to be aware of the risk factors that can increase your chances of developing it. Here are 8 things that can put you at a higher risk for breast cancer:
1. Age
Your risk of developing breast cancer increases as you age. Women over the age of 50 are at a higher risk than younger women.
2. Family History
Having a family history of breast cancer can increase your risk. If you have a mother, sister, or daughter who has had breast cancer, you may be at a higher risk.
3. Genetics
Certain genetic mutations, such as BRCA1 and BRCA2, can increase your risk of developing breast cancer. If you have a family history of these mutations, you may be at a higher risk.
4. Hormone Replacement Therapy
Taking hormone replacement therapy (HRT) for menopause can increase your risk of developing breast cancer. Talk to your doctor about the risks and benefits of HRT before starting it.
5. Alcohol Consumption
Drinking alcohol can increase your risk of developing breast cancer. The more you drink, the higher your risk. It’s best to limit your alcohol consumption to no more than one drink per day.
6. Obesity
Being overweight or obese can increase your risk of developing breast cancer. Maintaining a healthy weight can help reduce your risk.
7. Lack of Exercise
Not getting enough physical activity can increase your risk of developing breast cancer. Aim for at least 30 minutes of moderate exercise per day.
8. Smoking
Smoking can increase your risk of developing breast cancer. If you smoke, quitting can help reduce your risk.
It’s important to be aware of the risk factors for breast cancer and take steps to reduce your risk. Talk to your doctor about your risk and what you can do to reduce it.
Breast cancer in the USA affects 1 in 8 women and is the second most common cancer (after skin cancer). Approxmately 85% of breast cancer is non-invasive or early stage and curable if caught early. The other 15% is invasive breast cancer. There are many risk factors for developing breast cancer, some modifiable and some not. Read on to find out more—and to ensure your health and the health of others, don’t miss these Sure Signs You’ve Already Had COVID.
Age is one of the non-modifiable risk factor. The risk of breast cancer goes up as you age by about 8% per decade after age 40.

If you have a first-degree relative (mother, sister, daughter) with breast cancer, your risk is doubled. If you have two first-degree relatives with breast cancer, your risk is 5 times greater.

5-10% of breast cancers are thought to be hereditary and are linked to specific genetic mutations such as BRCA1 and BRCA2. Women with these mutations have a 50-85% chance of developing breast cancer in their lifetime.
