Conditions and Breast Cancer Types Treated at Gleneagles Hospitals in Mumbai
Breast cancer is broadly classified based on whether it has invaded surrounding breast tissue and on its hormone receptor status. At Gleneagles Hospitals, treatment planning is guided by biopsy results, imaging, and tumour marker testing.
Common Breast Cancer Types
Invasive Ductal Carcinoma (IDC)
IDC begins inside the milk ducts and then grows into the nearby breast tissue. It may also reach the lymph nodes in the underarm region in some cases.
Invasive Lobular Carcinoma (ILC)
ILC type begins in the lobules, which are the parts of the breast producing milk. Sometimes it does not show clearly on a mammogram, so an MRI may be advised if the findings are unclear.
Ductal Carcinoma In Situ (DCIS)
DCIS is described as the early form of breast cancer where the abnormal cells stay within the milk ducts. It is treatable, and early care helps reduce the chance of it turning into invasive cancer.
- Lobular Carcinoma In Situ (LCIS)
LCIS is not considered an invasive cancer, but it is linked with a higher risk of breast cancer in the future. Doctors usually advise planned follow-up and regular breast screening.
Breast Cancer Subtypes Based on Receptor Status
Breast cancers are also classified by hormone receptor status and HER2 status. These results guide treatment selection.
ER/PR Positive Breast Cancer
These cancers respond to hormonal therapy. They are usually managed with surgery, along with radiotherapy or chemotherapy when required, based on the stage and risk factors.
HER2 Positive Breast Cancer
HER2-positive breast cancers can be more aggressive, but they respond well to HER2-directed medicines when given with standard treatment. Targeted treatment has helped improve long-term control in many HER2-positive cases.
- Triple Negative Breast Cancer (TNBC)
This subtype does not show oestrogen, progesterone, or HER2 receptors. Treatment mainly involves chemotherapy, and immunotherapy may be considered in certain patients based on clinical evaluation.
Less Common Breast Cancer Types
Inflammatory Breast Cancer
This is a rare breast cancer type that can present with rapid breast swelling, redness, and skin changes. Immediate medical assessment is required. It needs prompt medical evaluation and a planned combination of treatments.
Paget’s Disease of the Breast
This affects the nipple area and may be associated with an underlying breast cancer.
Male Breast Cancer
Breast cancer may occur in men, though it is rare. Diagnosis is often delayed because symptoms are ignored. Treatment follows standard oncology protocols.
