Breast Cancer: What Happens in Body?

Breast cancer begins in the cells of the breast. The most common type of breast cancer is called ductal carcinoma, which starts in the cells of the milk ducts. Another common type of breast cancer is called lobular carcinoma, which starts in the cells of the milk glands.

Breast cancer can also occur in men, but it is much less common. In men, breast cancer usually starts in the cells of the milk ducts.

Breast cancer can spread to other parts of the body, such as the lungs, liver, and brain. This is called metastatic breast cancer. Metastatic breast cancer is usually not curable, but it can be treated to slow its progression and improve quality of life.

The exact cause of breast cancer is unknown, but there are a number of risk factors that can increase a woman's chance of developing the disease. These risk factors include:

* Age: The risk of breast cancer increases with age.

* Family history of breast cancer: Women who have a mother, sister, or daughter who has been diagnosed with breast cancer are at an increased risk of developing the disease.

* Certain genetic mutations: Women who have certain genetic mutations, such as BRCA1 and BRCA2, are at an increased risk of developing breast cancer.

* Dense breasts: Women with dense breasts have more connective tissue and less fatty tissue in their breasts. Dense breasts can make it more difficult to detect breast cancer on a mammogram.

* Certain lifestyle factors: Women who are overweight or obese, who drink alcohol, or who smoke cigarettes are at an increased risk of developing breast cancer.

Breast cancer can be diagnosed through a variety of tests, including mammograms, ultrasounds, and biopsies. Treatment for breast cancer depends on the stage of the disease and the patient's individual preferences. Treatment options may include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy.

Breast cancer is a serious disease, but it is also one that is often curable if it is caught early. By being aware of the risk factors for breast cancer and getting regular mammograms, women can help to increase their chances of early detection and successful treatment.
