Unraveling the Mystery: 8 Insights on Lobular Breast Cancer

Lobular breast cancer is a unique type of invasive breast cancer that accounts for about 10 percent of all breast cancer diagnoses. Unlike other types of breast cancer, lobular breast cancer originates in the milk-producing lobules of the breast rather than in the milk ducts. This characteristic can make it more difficult to detect and diagnose, and may also impact treatment decisions. In this article, we’ll explore eight key insights on lobular breast cancer to help you better understand this disease and what you can do if you or a loved one is affected.

Insight #1: Lobular breast cancer can be difficult to detect
Because lobular breast cancer originates in the lobules rather than in the ducts, it can be more difficult to detect on mammograms and other imaging tests. In fact, up to 30 percent of cases are missed on mammograms, and diagnosis is often delayed as a result. This underscores the importance of performing regular breast self-exams and seeking medical attention if you notice any changes or abnormalities.

Insight #2: Lobular breast cancer often presents as a subtle thickening or fullness in the breast
Many women with lobular breast cancer report feeling a subtle thickening or fullness in the breast, rather than a palpable lump. This can make diagnosis even more challenging, as these changes may be difficult to detect on imaging studies or during routine physical exams.

Insight #3: Lobular breast cancer is often treated with surgery and hormone therapy
Because lobular breast cancer is often estrogen-receptor positive (meaning that it responds to the hormone estrogen), treatment typically consists of surgery to remove the cancerous tissue, followed by hormone therapy to prevent the cancer from returning.

Insight #4: Chemotherapy may be less effective for lobular breast cancer
Because lobular breast cancer is less likely to form discrete masses or tumors, it may be less responsive to chemotherapy, which targets rapidly dividing cells. This underscores the importance of early detection and prompt treatment with surgery and hormone therapy.

Insight #5: Family history may increase your risk of developing lobular breast cancer
Although most cases of lobular breast cancer occur sporadically, a family history of the disease can increase your risk. If you have a first-degree relative (such as a mother, sister, or daughter) who has been diagnosed with lobular breast cancer, you may be at increased risk and should talk to your doctor about screening and risk reduction strategies.

Insight #6: Breastfeeding may lower your risk of lobular breast cancer
Research suggests that breastfeeding may lower your risk of developing lobular breast cancer, possibly due to the protective effects of lactation on the breast tissue. If possible, aim to breastfeed for at least six months to a year after giving birth to reduce your risk.

Insight #7: Lobular breast cancer may recur in other parts of the body
Because lobular breast cancer cells can spread to other parts of the body (a process known as metastasis), ongoing surveillance and monitoring are essential to detect and treat recurrence as early as possible.

Insight #8: Support is available for those with lobular breast cancer
If you or a loved one has been diagnosed with lobular breast cancer, remember that you are not alone. Support groups and organizations such as the Lobular Breast Cancer Alliance can provide valuable resources and connections to others who have been through a similar experience.

In conclusion, lobular breast cancer is a unique and challenging type of breast cancer that requires close attention and care. By staying informed and proactive, you can take steps to reduce your risk, detect the disease early, and navigate treatment and recovery with confidence.
