Remember: Seven factors that may easily induce breast cancer

As one of the most common malignant tumors in women, the incidence of breast cancer accounts for 7-10% of all malignant tumors in the body. What are the causes of breast cancer ? The following will introduce the causes of breast cancer.

The most common causes of breast cancer are:

1 Age: In women, the chance of developing breast cancer increases with age. It is rare before menarche and before the age of 20, but the incidence of breast cancer rises rapidly after the age of 20. It is higher between the ages of 45 and 50, but is relatively flat. The incidence continues to rise after menopause and reaches its peak around the age of 70. The mortality rate also increases with age, gradually increasing after the age of 25 and maintaining an upward trend until old age.

2 Genetic factors: Women in the family with a history of breast cancer in the first-degree direct family have a 2 to 3 times higher risk of developing breast cancer than the normal population.

3 Weight gain may be an important risk factor for breast cancer in postmenopausal women.

4. Age of menarche: Those whose menarche occurs before the age of 13 have a 2.2 times higher risk of developing breast cancer than those whose menarche occurs after the age of 17.

5. Age at menopause: Those who reach menopause at an age greater than 55 have an increased risk compared to those who reach menopause at an age less than 45.

6 Age of first pregnancy: The risk gradually increases with the delay of the age of first birth. The risk of first birth after the age of 35 is higher than that of those with no childbearing history.

7. Estrogen supplementation after menopause: Long-term use of estrogen during menopause may increase the risk of breast cancer.

The above is an introduction to the causes of breast cancer. Understanding the causes of breast cancer can help patients better cooperate with the doctor's treatment and get rid of the torture of the disease as soon as possible.
