Triple Positive Breast Cancer

Triple positive breast cancer refers to a specific subtype of breast cancer that is characterized by the presence of three hormone receptors: estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). These receptors play a crucial role in the growth and development of breast cancer cells.


In triple positive breast cancer, the cancer cells have receptors for estrogen, progesterone, and HER2, which means they can be influenced by these hormones and growth factors. This subtype accounts for approximately 15-20% of all breast cancer cases.


The presence of these hormone receptors has important implications for treatment options. Hormone therapy, such as selective estrogen receptor modulators (SERMs) or aromatase inhibitors, can be used to block the effects of estrogen and progesterone on cancer cell growth. Additionally, targeted therapies that specifically target the HER2 receptor, such as trastuzumab (Herceptin), can be used to inhibit the growth of HER2-positive cancer cells.


The treatment approach for triple positive breast cancer often involves a combination of surgery, chemotherapy, radiation therapy, hormone therapy, and targeted therapy. The specific treatment plan will depend on various factors, including the stage of the cancer, the individual's overall health, and the presence of any other genetic mutations.


It is important to note that triple positive breast cancer can have different prognoses and responses to treatment compared to other subtypes of breast cancer. Therefore, it is crucial for individuals diagnosed with triple positive breast cancer to work closely with their healthcare team to develop a personalized treatment plan and to regularly monitor their response to treatment.

before cancer.....

Before my breast cancer diagnosis, I was incredibly shallow. I was obsessed with my appearance and always striving to live up to the model image I had created for myself. I even dreamed of posing for Playboy one day. But after a double mastectomy, I am now so self-conscious that I can hardly recognize myself. It took me almost a month to look down at my chest after the surgery. I cried and cried for hours in the bathroom, wondering how this could be happening to me. I had always been so confident in my body, and now I felt like a stranger in my own skin. As a mother, I struggled with how to teach my daughter to be confident when I was struggling so much myself. How could I tell her to love herself when I didn't even recognize myself anymore? I was grateful for my surgeon's skilled hands and for getting the cancer out, but I hated the results. When people say that a mastectomy is not a boob job, they are right. The scars and the fact that I will never have sensation again at 34
