What Are the Most Common Breast Cancer Types?


Breast cancer takes place when breast cells mutate and become cancerous cells that multiply and form tumours. The best breast cancer surgery doctor in Kolkata tells us about the most common breast cancer types.

Types of breast cancer

The following are the most common types of breast cancer:

  • Ductal Carcinoma In Situ (DCIS)

DCIS refers to non-invasive breast cancer. Abnormal cells are found in the lining of the breast milk ducts. It is often detected through mammograms and is considered a precursor to invasive breast cancer. 

  • Invasive Ductal Carcinoma (IDC)

IDC is the most common kind of invasive breast cancer. It begins in the milk ducts but then invades surrounding breast tissue. 

  • Invasive Lobular Carcinoma (ILC)

ILC begins in the milk-producing glands (lobules) of the breast and can spread to nearby tissue.

  • Triple-Negative Breast Cancer (TNBC)

TNBC is characterized by missing human epidermal growth factor receptor 2 (HER2), estrogen receptors and progesterone receptors.

  • HER2-Positive breast cancer

HER2-positive breast cancer over-expresses the human epidermal growth factor receptor 2 (HER2) protein. 

In case the suspicion arises of breast cancer, consider visiting the best cancer hospital in North Kolkata for early diagnosis.

Breast cancer subtypes

Breast cancer subtypes are classified by receptor cell status. Receptors are protein molecules in or on cells’ surfaces. They may attract or attach to certain substances in your blood, including hormones like estrogen and progesterone. Estrogen and progesterone help cancerous cells to grow.

The subtypes are as follows:

  • ER-positive (ER+) breast cancers have estrogen receptors.

  • PR-positive (PR+) breast cancers possess progesterone receptors.

  • HR-positive (HR+) breast cancers have both estrogen and progesterone receptors.

  • HR-negative (HR-) breast cancers do not have estrogen or progesterone receptors.

  • HER2-positive (HER2+) breast cancers have higher than normal levels of the HER2 protein.

Conclusion

Each type of breast cancer presents its own set of challenges and considerations. The best breast cancer surgery doctor in Kolkata develops personalized treatment plans tailored to the needs of individuals. Early detection, accurate diagnosis, and access to comprehensive care are essential in improving outcomes.
