Why is triple-negative breast cancer considered aggressive?

Question

Hello doctor,

I am 57 years old and recently discovered a small, hard lump in my left breast during a self-exam. After undergoing tests, it was confirmed as triple-negative breast cancer, stage II, localized to the breast and nearby lymph nodes. I completed chemotherapy, which shrunk the tumor, allowing for a lumpectomy, followed by three radiotherapy sessions. Although I am relieved at the progress, I am haunted by several questions. Why is this form of cancer so aggressive? Will it recur, and how can I monitor it? Is this ever truly 'over,' or will I always be looking over my shoulder? I have three grandchildren, and I am extremely worried about them. Please provide your suggestions. Please guide me.

Thank you.

Hello,

Welcome to icliniq.com.

Thank you for posting your query.

You have been diagnosed with triple-negative breast cancer at the age of 57 and have undergone all necessary treatments: chemotherapy to downstage the tumor, followed by a lumpectomy, and radiotherapy. Fortunately, the disease was detected at an early stage and treated accordingly.

Triple-negative breast cancer is an aggressive type that grows quickly and generally has a poorer prognosis than hormone receptor-positive types.

Since you have undergone breast-conserving surgery along with radiotherapy, you will need to follow a structured follow-up schedule, which includes:

Clinical examinations every three months for the first two years.
Clinical examinations every six months for the subsequent three years.
Annual clinical examinations thereafter.
Annual mammograms.

It is crucial to adhere to these follow-up guidelines to monitor for any recurrence of the disease. Breast cancer can be hereditary, so screening is recommended for first-degree relatives, especially females at a younger age:

Women under 40 years of age are less likely to have breast cancer. However, those with a family history of breast cancer or a history of chest radiation may need a breast MRI (magnetic resonance imaging) and ultrasound starting at ages 25 to 30 years, along with self-exams and clinical breast exams.
Women over 40 years of age should have a mammogram every one to two years, depending on their risk group and following specific guidelines.

I hope I have addressed all your concerns.

I would appreciate your feedback.

Thank you.
