Types of Breast Cancer: Exploring Different Subtypes and Their Characteristics

Breast cancer is a complex condition that affects millions of people worldwide. It is not a single entity but rather a collection of different subtypes, each with its own unique characteristics and treatment approaches. Understanding the various types is crucial for accurate diagnosis, personalized treatment plans, and improved patient outcomes. And you can look for an oncology hospital in Bangalore that provides you with the best treatment. This article explores some of the most common subtypes and their distinct features.

Types of Breat Cancer

Ductal Carcinoma In Situ (DCIS): 

It is considered a non-invasive type, where abnormal cells are confined to the milk ducts and might not have spread to surrounding tissues. While it is not life-threatening, if left untreated, DCIS can progress to invasive cancer. Treatment usually involves surgical removal of abnormal cells, often followed by radiation therapy.

Lobular Carcinoma In Situ (LCIS):

Similar to DCIS, LCIS is a non-invasive type. It originates in the milk-producing glands (lobules) but does not spread beyond them. Management typically involves regular surveillance and close monitoring rather than immediate treatment.

Invasive Ductal Carcinoma (IDC): 

IDC is the most common type, accounting for about 80% of cases. It begins in the milk ducts and infiltrates the surrounding breast tissue. It can also spread to other parts of the body if not treated early. Treatment options include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of such therapies, depending on the stage and characteristics of the tumor.

Types of Breast Cancer

Invasive Lobular Carcinoma (ILC): 

ILC starts in the milk-producing glands and can spread to nearby breast tissues and beyond. It accounts for about 10-15% of all cases. Unlike IDC, ILC tends to form a single-file pattern of cells, making it harder to detect on imaging tests. Treatment approaches for ILC are similar to IDC, although some differences may exist based on the tumor’s characteristics.

Triple-Negative Breast Cancer (TNBC): 

TNBC is a subtype characterized by the absence of three hormone receptors: PR (progesterone receptor), ER (estrogen receptor), and HER2 (human epidermal growth factor receptor 2). It comprises about 10-20% of all cancers. TNBC tends to be more aggressive and may have a higher risk of recurrence. Chemotherapy is the mainstay of TNBC treatment, as hormonal and targeted therapies are not effective. And you can search for the best hospital for cancer surgery in Bangalore for such treatment. 

Hormone Receptor-Positive Breast Cancer:

This subtype, accounting for approximately 75% of cancers, is characterized by the presence of estrogen and/or progesterone receptors. These receptors promote the growth of cancer cells. The treatment often includes hormonal therapies such as tamoxifen or aromatase inhibitors, which block or reduce the effects of estrogen.

HER2-Positive Breast Cancer:

It accounts for around 15-20% of cases. It tends to be more aggressive. Targeted therapies like trastuzumab (Herceptin) and pertuzumab (Perjeta) have significantly improved outcomes for patients, often combined with other treatment modalities.

Paget’s Disease of the Breast:

Paget’s disease is a rare form that affects the skin of the nipple and areola. It is characterized by redness, scaling, itching, and crusting of the nipple area. In some cases, an underlying tumor may be present. Treatment for Paget’s disease often involves surgery to remove the affected tissue, followed by additional treatments such as radiation therapy or chemotherapy, depending on the extent of the disease.

In conclusion

breast cancer is a diverse disease with several distinct subtypes, each requiring a different approach to diagnosis and treatment. And you can search for an oncology hospital in Bangalore that provides you with excellent treatment. Understanding the characteristics of these subtypes is essential for developing personalized treatment strategies and improving patient outcomes. Advances in research and technology continue to shed light on the intricacies, bringing everyone closer to more effective treatments and improved survival rates for those affected by this disease.
