Risk factors for female breast cancer

What are the risk factors for breast cancer in women? I believe many people have this question. Breast cancer is the second largest killer among female cancers, but among women aged 45 to 55, breast cancer is the number one killer among female cancers. Let's follow the experts to learn about the risk factors for breast cancer .

1. Gender is one of the risk factors for breast cancer. As a woman, you are at the greatest risk of breast cancer.

2. Age factor. As age increases, the likelihood of developing breast cancer also increases.

3. Genetic factors are also a major risk factor for breast cancer. Studies have shown that about 5-10% of breast cancer patients suffer from mutations in certain genes (especially BRCA1 and BRCA2 genes). If a woman inherits a mutated gene from her parents, she is more likely to develop breast cancer than other people. More than half of women with inherited mutated genes will develop breast cancer by the age of 70.

4. Family history factors. If a close relative in the family has had breast cancer, then her chance of developing breast cancer is higher than the average person. If her mother, sister, or daughter has had the disease, then her risk of developing breast cancer will be twice as high. If her relative had breast cancer before the age of 50, then her chance of developing the disease is even higher. This is also a risk factor for breast cancer.

5. Medical history factors: If breast cancer cells have been found in one breast, the chance of developing the disease in the other breast is greatly increased.
