What You Need to Know About Breast Cancer
Words by Maggie Downs
October is Breast Cancer Awareness Month, a time to highlight the importance of early detection and education in the fight against the disease. To provide valuable insights, DAP Health Director of OB-GYN Services Dr. Rhett Papa answered key questions about breast cancer, including stages, treatments, and risk factors.
What are some early signs and symptoms of breast cancer?
Most breast cancers are detected through routine screenings, so there aren’t typically noticeable symptoms for patients to monitor at home. That’s why annual gynecologic care is so important. It’s rare for a patient to discover a significant lump that wasn’t already found during a physical exam, and only about 5% experience breast pain.
How can breast cancer be detected early, and what screening methods are recommended?
There is a growing push for easier access to breast cancer screening. In California, for example, patients can now request an annual screening mammogram without needing a doctor’s referral. While there’s some debate about the ideal age to begin screening, I recommend starting at age 40 for women without a family history of breast cancer. However, if you have a first-degree relative (such as a mother or sister) who had breast cancer, it’s advised to start screening 10 years before the age at which they were diagnosed. For instance, if your mother was diagnosed at 45, you should begin screenings at 35.
What are the main risk factors for developing breast cancer?
Contrary to public belief, only about 5 to 10% of patients who are diagnosed with breast cancer have any family history, so lifestyle is a significant area of focus. Some risk factors are obesity, early age of onset of your menstrual cycle (before age 12), a late entry into menopause after the age of 55. All seem to be focused around your body’s production of estrogen. Excessive alcohol consumption can also increase your risk.
What lifestyle changes can reduce the risk of breast cancer?
Maintaining a healthy weight is important. Practicing regular exercise. Eating a healthy diet. There’s some suggestion that a lot of the inflammatory foods and additives we have in our diets could support the development of cells growing abnormally. Breastfeeding, as long as a mother feels that she can, is helpful.
If there is a family history, should a patient consider genetic testing?
I don’t discourage my patients from ever seeking genetic testing. It may be a little bit costly if your insurance doesn’t feel like your family risk is high enough. But yes, certainly everyone who wants to know their risk shouldn’t be discouraged from seeking genetic testing.
What are the different stages of breast cancer?
Breast cancer is categorized into four stages, but fortunately, most cases are now detected early — in stages one and two.
Stage one is the earliest stage, where the tumor is small (usually less than 2 centimeters) and may or may not have spread to nearby lymph nodes. The cancer is localized, making treatment options like surgery (lumpectomy or mastectomy) and radiation typically effective.
Stage two breast cancer involves a larger tumor (2 to 5 centimeters) or has spread to nearby lymph nodes. While it is still considered early-stage, the involvement of lymph nodes may require more comprehensive treatment.
In stage three, the cancer is considered more advanced. It typically involves larger tumors and a higher number of affected lymph nodes. This stage often requires more aggressive treatment.
In stage four, the cancer has metastasized, meaning it has spread to other parts of the body. Treatment at this stage focuses on controlling the disease and improving quality of life, often involving systemic therapies like chemotherapy, hormone therapy, or targeted treatments.
What treatment options are available?
Treatment varies depending on the stage and type of cancer, but common approaches include surgery, radiation, chemotherapy, hormone therapy, and targeted therapies. Surgery is often used to physically eliminate the cancer. Radiation therapy uses high-energy rays to kill remaining cancer cells in the breast or surrounding areas. Chemotherapy involves drugs that target and destroy cancer cells throughout the body, while hormone therapy blocks hormones that fuel certain breast cancers. Targeted therapies focus on specific cancer cell characteristics, like proteins that help the cancer grow. In many cases, a combination of these treatments is used to maximize effectiveness.
How can breast cancer treatments like chemotherapy or radiation affect long-term health beyond cancer itself?
Breast cancer treatments such as chemotherapy and radiation can have lasting effects beyond the cancer itself. Many patients experience mental health challenges — including anxiety and depression — following a diagnosis and treatment. Physically, overall vitality may decrease, with fatigue being a common issue. Cognitive function, often referred to as chemo brain, can also be impacted, leading to challenges with memory and concentration.
How does breast cancer affect fertility, and what options are available for women who want to have children after treatment?
Chemotherapy is quite toxic to the ovaries, and so if a patient is not done with childbearing and has an evaluation prior to the initiation of radiation or chemotherapy, we can evaluate her future fertility possibilities. Women may choose to freeze their eggs (egg cryopreservation) or embryos (embryo cryopreservation) for future use. Another option is ovarian tissue preservation, where a portion of ovarian tissue is removed and frozen for reimplantation later. In some cases, medications like gonadotropin-releasing hormone agonists can be used to protect the ovaries.
Can men get breast cancer, and what are the signs and risk factors for male breast cancer?
Yes, men can get breast cancer. Men should be aware of any changes in their breast tissue, similar to how they might check for testicular cancer. Key signs include feeling for lumps or nodules, especially under the nipple, as well as changes in texture, fullness, or appearance. Men with a strong family history of breast cancer should discuss screening options, such as an ultrasound or mammogram, with their doctor. Early detection is important for everyone, but currently the risk of breast cancer for a man is about 100 times lower than for a woman.
