Breast Cancer: What It Is, How To Prevent It, and What To Do If You’re Diagnosed
Breast cancer is a type of cancer that starts in the cells of the breast. It is the most common cancer among women in the United States, with an estimated 281,550 new cases and 43,600 deaths in 2021.
What are the risk factors for breast cancer?
There are many risk factors for breast cancer, including:
- Age: The risk of breast cancer increases with age. Most cases of breast cancer occur in women over the age of 50.
- Family history: Women who have a family history of breast cancer are at an increased risk of developing the disease.
- Genetics: Some women are born with genes that increase their risk of breast cancer.
- Hormones: Women who take hormone replacement therapy (HRT) are at an increased risk of breast cancer.
- Lifestyle factors: Women who are overweight or obese, who drink alcohol, or who smoke are at an increased risk of breast cancer.
What are the symptoms of breast cancer?
The most common symptom of breast cancer is a lump in the breast. Other symptoms of breast cancer can include:
- Thickening or swelling of the breast
- Nipple discharge
- Pain in the breast or nipple
- Changes in the shape or size of the breast
- Skin irritation or dimpling
- Bloody discharge from the nipple
How is breast cancer diagnosed?
Breast cancer is diagnosed with a mammogram, which is an X-ray of the breast. If a mammogram shows a suspicious area, your doctor may recommend a biopsy, which is a procedure to remove a small sample of tissue from the breast for examination under a microscope.
How is breast cancer treated?
The treatment for breast cancer depends on the stage of the cancer, which is determined by the size of the tumor, whether it has spread to other parts of the body, and whether there are any other risk factors. Treatment options for breast cancer can include:
- Surgery: Surgery to remove the tumor and some of the surrounding tissue is the most common treatment for breast cancer.
- Radiation therapy: Radiation therapy uses high-energy beams to kill cancer cells.
- Chemotherapy: Chemotherapy uses drugs to kill cancer cells.
- Hormone therapy: Hormone therapy uses drugs to block the effects of hormones that can promote breast cancer growth.
- Targeted therapy: Targeted therapy uses drugs that target specific molecules that are involved in breast cancer growth.
What is the prognosis for breast cancer?
The prognosis for breast cancer depends on the stage of the cancer and the patient’s overall health. The five-year survival rate for breast cancer is 90% for women who are diagnosed with early-stage breast cancer. The five-year survival rate for women who are diagnosed with late-stage breast cancer is 28%.
How can I prevent breast cancer?
There are no surefire ways to prevent breast cancer, but there are some things you can do to reduce your risk, including:
- Get regular mammograms: Mammograms can detect breast cancer early, when it is most treatable.
- Maintain a healthy weight: Obesity increases your risk of breast cancer.
- Eat a healthy diet: A healthy diet that is rich in fruits, vegetables, and whole grains can help to reduce your risk of breast cancer.
- Get regular exercise: Exercise can help to reduce your risk of breast cancer.
- Limit alcohol intake: Alcohol increases your risk of breast cancer.
- Don’t smoke: Smoking increases your risk of breast cancer.
What should I do if I’m diagnosed with breast cancer?
If you are diagnosed with breast cancer, it is important to remember that there are many treatment options available and that the prognosis for breast cancer is good. Talk to your doctor about the best treatment options for you and follow their instructions carefully.
