Breast cancer is a type of cancer that develops from breast tissue. It is the most common invasive cancer in women and the second most common type of cancer overall. While it can occur in men, the risk is far less.
In this article, we will discuss the main causes behind the development of breast cancer. Knowing the risk factors can help individuals take the necessary preventive steps to reduce their risk.
1. Age: As we age, our risk of breast cancer increases. Most breast cancers are seen in women age 50 or older. It is estimated that about one in eight breast cancer cases occur in women under 45.
2. Weight and Activity Levels: Being overweight or obese increases your risk of breast cancer. Staying active is also important to reduce your risk. Regular physical activity can help keep your body weight at a healthy level.
3. Gender: As mentioned before, breast cancer primarily affects women. Although men can also have breast cancer, the risk is much lower.
4. Genetics: Your genetics can play a role in your risk of breast cancer. A hereditary breast cancer gene mutation (such as mutations in BRCA1 and BRCA2) is responsible for around 5-10% of breast cancer cases.
5. Hormone Exposure: Some evidence suggests that hormones, such as estrogen and some types of birth control pills, may increase the risk of breast cancer.
6. Alcohol Consumption: Research suggests that alcohol consumption increases the risk of breast cancer. It is recommended to limit your alcohol consumption to reduce your risk.
7. Family History of Breast Cancer: Having a close family member (such as a mother, sister, or aunt) with breast cancer can also increase your risk.
By knowing the main causes of breast cancer, individuals can take the necessary preventive steps to reduce their risk. It is important to speak to your doctor to discuss your risk and decide together the best plan of action for you.
Regular screening is also important to detect any changes that may be an early sign of a problem. This is especially true for women over 50 or those who are at high risk due to family history. Early detection can help with early treatment and improve the chances of successful treatment.
