Breast Cancer Treatment in India
What is Breast Cancer?
Breast cancer refers to a gathering of cancerous cells originating from breast cells. While it predominantly occurs in women, it can also affect men, albeit infrequently. The initiation of breast cancer typically involves the development of calcium deposits or the formation of a localized small tumor. These cancer cells can then disseminate through the bloodstream to various organs or channels within the breast, including the lymph nodes. The rate of spread and growth varies, and breast cancer has the potential to extend beyond the confines of the breast itself.
Symptoms of Breast Cancer
Breast cancer, during its initial stages, often manifests without noticeable symptoms. Nevertheless, as the condition progresses, certain symptoms may emerge :
Male breast cancer often presents with common symptoms such as tenderness, breast lumps, and breast pain.

Types of Breast Cancer
Invasive Breast Cancer : Invasive breast cancer occurs when cancer cells extend beyond the lining of lobules or ducts, infiltrating the surrounding breast tissue. This form of breast cancer can be classified into various types:
Ductal carcinoma in situ (DCIS) : This is regarded as one of the earliest forms of breast cancer. The cancer cells are confined to the breast ducts and have not spread to the surrounding breast tissue.
HER2 positive breast cancer : HER2 positive breast cancer occurs when there is an elevated presence of a protein called HER2 on the surface of breast cancer cells.
Rarer Type of Breast Cancer
Stages of Breast Cancer
Stages of breast cancer depends on four things :
Different stages include :
Stage 0 : This stage encompasses non-invasive breast cancers, including ductal carcinoma in situ (DCIS).
Stage I : In the classification of breast cancers, Stage 1 delineates invasive cancers. Stage 1 is further divided into 1A and 1B. In Stage 1A, the cancer remains confined within the breast without spreading, and the tumor size is approximately 2 cm. In Stage 1B, the tumor is also less than 2 cm, and it involves small clusters of cancer cells.
Stage II : Stage IIA and IIB are the two subcategories within this stage. Invasive breast cancer is characterized in Stage IIA, where:
Invasive Breast Cancer is delineated in Stage IIB, where:
Stage III : In Stage IIIA, one of the sub-categories of Stage 3, invasive breast cancer is characterized by :
In Stage IIIB, a sub-category of Stage 3, invasive breast cancer is characterized by:
In Stage IIIC, a sub-category of Stage 3, invasive breast cancer is characterized by :
Stage IV : In Stage IV, the invasive breast cancer has extended its reach beyond the breast, spreading to surrounding lymph nodes and distant organs such as bones, brain, lungs, and skin.
Diagnosis of Breast Cancer
During a physical examination of a patient, areas such as the armpits, chest, breasts, and neck are thoroughly assessed. Several tests are conducted to diagnose breast cancer, including:
