Breast cancer occurs when cells in the breast tissue grow abnormally and out of control. Although the exact cause of breast cancer is not yet known, there are certain risk factors that increase a person’s chances of developing it, such as:
- Gender: Breast cancer is more common in women than men.
- Age: The risk of developing breast cancer increases as a person gets older.
- Family history: Having a family history of breast cancer increases the risk of developing the disease.
- Hormones: Certain hormone levels, such as estrogen and progesterone, can affect the growth of breast cancer cells.
- Lifestyle factors: Being overweight or obese, drinking alcohol excessively, and not exercising regularly can also increase the risk of developing breast cancer.
The exact process of how breast cancer starts is not fully understood, but it is believed that changes or mutations in the DNA of breast cells may play a role. These mutations can cause the cells to divide and grow uncontrollably, forming a mass or lump (tumor) in the breast. Over time, cancer cells may break away from the original tumor and spread to other parts of the body, a process called metastasis. Early detection and treatment are crucial for improving the chances of survival and reducing the risk of complications from breast cancer.
