Breast cancer is caused by abnormal cell mutation in the breasts. Most breast cancers begin in the ducts or lobules, and they can spread outside the breast through blood vessels and lymph vessels. There are various types of breast cancer, including invasive ductal carcinoma and invasive lobular carcinoma. The precise cause of cancer is yet to be determined. However, experts believe that certain factors might put one at risk of developing it

1. Genetics
One of the most common risk factors of breast cancer is genetics. It is indicated that about 5 to 10 percent of breast cancers are linked to gene mutations passed through generations of a family. The most commonly inherited mutated genes are breast cancer gene 1 (BRCA1) and breast cancer gene 2 (BRCA2), both of which increase the risk of breast and ovarian cancer. Those with a family history of breast cancer might need to undergo a blood test to identify if the specific mutations are passed through the family.

2. Age
An individual may develop breast cancer at any age throughout their lifetime. However, experts indicate that people are at a higher risk of the disease as they age. Most cancers develop after age 50, and the median age for developing breast cancer is 63.

3. A history of breast conditions
Someone with a history of breast-related health complications might also be at a higher risk of developing cancer. For instance, if an individual has undergone a breast biopsy that found lobular carcinoma in situ (LCIS) or atypical hyperplasia of the breast, they are more likely to be at risk of breast cancer. Moreover, if a person has had breast cancer in one breast, they are also at a heightened risk of developing cancer in the other breast.

4. Exposure to radiation
One might be exposed to radiation through certain treatments. If the radiation is focused on the chest in the individual’s childhood or as a young adult, they are at a higher risk of developing cancerous cells in the breast that might affect their life.

5. Reproductive history
Studies show that women who start menstrual periods before age 12 and start menopause after age 55 might be prone to breast cancer. The development might result from extended exposure to certain hormones in the body.

6. Dense breasts
Individuals with dense breasts are at an increased risk of developing cancer in this region. The common reason for this is associated with more dense fatty tissue, which could sometimes make it hard to see tumors on a mammogram. The lack of proper diagnosis and treatment may consequently lead to a faster progression of breast cancer.

7. Having the first child at an older age
One of the most common causes and triggers of breast cancer is associated with giving birth to a child at an older age. The mutation might occur in those who give birth after age 30. Therefore, one must see a healthcare expert if they suspect any unusual developments in this scenario.

8. Unhealthy lifestyle
People who follow an unhealthy lifestyle might also be at risk of developing breast cancer. For instance, those who eat unhealthy foods might suffer from increased BMI, which is a common trigger for cancers, including that of the breast. Moreover, regularly eating packs and processed foods that contain preservatives may also increase the risk of cancer.
