What is Multifocal Breast Cancer? Key Facts Patients Should Know

Key facts about Multifocal Breast Cancer

Many studies indicate that multifocal breast cancer is a common, not a rare type of cancer, with some studies suggesting that its incidence could be up to 60% of invasive breast cancers. Patients with these types of cancers might experience various lumps within the same breast. These tumours can be at different stages of development, which makes the symptoms less visible.

If you start to notice any sudden changes in your breasts, then consult an experienced breast cancer specialist immediately.

Some of the symptoms of these cancers may include dense breast tissue, or lumps, if you experience any of these signs, then do not ignore it; get an immediate medical evaluation as soon as possible.

Treatments

The treatment for multifocal breast cancer is often considered as complex and includes a multimodal treatment approach, including medical oncologists, radiation oncologists, and surgeons. The main goal of treatment is to remove cancer while preserving the breast as much as possible. 

Surgical procedures for multifocal breast cancer can include lumpectomy or mastectomy, with the possibility of sentinel lymph node biopsy or axillary lymph node dissection. Additionally, there are treatments such as adjuvant therapies like chemotherapy, targeted therapy, hormone therapy, and radiation therapy that are used to reduce the risk of cancer recurrence.

Chemotherapy is a systemic treatment that uses drugs to destroy cancer cells. These can be used to employ before surgery (neoadjuvant) to shrink tumors or after the surgery (adjuvant therapy) to reduce the risk of cancer recurrence in patients. However, targeted therapy and hormone therapy mainly focus on specific molecules that are involved in the growth and spread of cancer cells.

Radiation therapy often uses high energy X-rays to destroy cancer cells and shrink tumours. These treatments can be administered through a machine called external beam radiation or internally through the implantation of radioactives beams, also known as brachytherapy.

Outlook and prognosis

The survival rates for this type of cancer can vary, mainly depending on several factors, including the stage of your cancer, key characteristics of the tumor, and the selected treatment options. It's vital to understand that this cancer diagnosis is not the end of your life. Women diagnosed with this type of cancer live healthy and improved, fulfilling lives after the treatments.  

Understanding the survival rates of these cancers can help the patients with expected treatment outcomes associated with the timing of your diagnosis. However, there are factors like age, individual health conditions, and response to treatments can greatly affect the treatment outcomes. 

Multifocal breast cancer is two or more tumors that originate from an original tumor from one single breast, but they all originate from the same tumor, not developed independently from it. Cancer research has shown a 5-year survival rate, while the 5-year survival rate for cancer that is confined to the breast is 99 percent. If the cancer has spread to the lymph nodes in the area, then the expected survival rate of 5 years would be 85%.
