Understanding Invasive Lobular Carcinoma (ILC): A Q&A Based on Recent Findings
Recent research highlights a concerning trend: an increase in cases of Invasive Lobular Carcinoma (ILC), a specific type of breast cancer. HereS a breakdown of what you need to know, based on expert insights:
Why is ILC harder to detect with standard mammograms?
ILC differs from more common breast cancers.Rather of forming a distinct lump, ILC cells spread in thin lines within the breast tissue, frequently enough mimicking normal tissue on imaging. This makes subtle changes, or even no changes, appear on a mammogram. Women may also not feel a noticeable lump during self-exams, delaying diagnosis.
What imaging techniques can detect ILC?
While mammography remains the primary screening tool, breast ultrasound and MRI can be helpful. Ultrasounds can identify areas of thickening missed by mammograms, and MRIs provide a more detailed view, particularly useful in dense breast tissue. Though, these aren’t routinely recommended for everyone; they are frequently enough suggested for women at higher risk (dense breasts, strong family history, genetic mutations).
Who is most at risk for ILC,and is the incidence rising?
ILC is increasing across all racial and ethnic groups,but the most important rise is among Asian American and Pacific Islander women. Age is also a key factor – women 65 and older are more likely to be diagnosed with ILC than other types of breast cancer. Approximately 70% of new ILC cases are found in women over 60, with a median diagnosis age of 66.
What’s driving this increase in ILC cases?
Several factors are likely contributing. Because ILC is hormone-sensitive,changes in hormone exposure over time play a role. Rising rates of obesity and alcohol consumption, alongside shifts in childbearing and menopause patterns, may also be contributing. Improved diagnostic accuracy and increased awareness are also likely factors – some ILC cases may have been previously misclassified as a different type of breast cancer. increased longevity means more women are living to ages where ILC is more common.
How is ILC treated?
Treatment generally follows the same principles as other breast cancers: surgery, radiation, and hormonal therapy (as most ILC tumors respond to estrogen or progesterone). Chemotherapy is used in some cases. Newer targeted drugs, combined with hormonal therapy, offer hope for advanced disease. Though, ILC can be more resistant to treatment, particularly when it has spread, and frequently enough carries a less favorable prognosis.
What can women do to reduce their risk?
While some risk factors are unavoidable, lifestyle choices can substantially impact your risk. Quitting smoking, limiting alcohol intake, maintaining a healthy weight, and regular physical activity are all beneficial.A diet rich in fruits, vegetables, and whole grains supports overall health and may reduce cancer risk.
The importance of early detection:
Regular screening, understanding what’s normal for your breasts, and discussing your individual risk factors with your doctor are crucial. pay attention to any changes - thickening, swelling, nipple discharge, skin discoloration, or new areas of fullness – and seek medical attention promptly.
