Cancer / Oncology Treatments

Breast Cancer

A collection of cancer cells that arise from the cells of the breast is known as breast cancer. Breast cancer is majorly seen in women, though rare but it also affects men. The calcium deposits or formation of a confined small tumor is the beginning of any breast cancer that spread from the blood stream into the other organs or different channels inside the breast into the lymph nodes. The rate of spread and growth are different that can spread even further than the breast.

Types of Breast Cancer

Invasive Breast Cancer: Invasive breast cancer develops when cancer cells spread outside the lining of lobules or ducts into the nearby tissue of the breast. Invasive breast cancer can be categorized into different types –

  • Triple Negative Breast Cancer: There are no receptors in this type of cancer for HER2 protein, estrogen or progesterone.
  • Inflammatory Breast Cancer: This is considered as not so common type of breast cancer. This cancer develops when cancer cells blocks lymph vessels of the breast skin. In this, the breast may become swollen or inflamed.
  • Invasive Ductal Breast Cancer: When cancer cells that line the duct have spread into nearby breast tissue then it results in invasive ductal breast cancer.
  • Paget’s disease of the Breast: A scaly or red rash is visible on the skin of the nipple that results in this type of breast cancer. Women who are suffering from this may also have invasive breast cancer or DCIS.
  • Invasive Lobular Breast Cancer: This type develops from the cells lining the breast lobes and this type is hard to diagnose on a mammogram.

Ductal carcinoma in situ (DCIS): This is considered as the one of the earliest forms of breast cancer. The cancer cells are present in the breast ducts though they have not spread to nearby breast tissue.

HER2 positive breast cancer: When there is a large number of protein (known as HER2) in breast cancer cells on their surface then it results in HER2 positive breast cancer.

Rarer Type of Breast Cancer

  • Malignant phyllodes tumor
  • Medullary breast cancer
  • Tubular breast cancer
  • Mucinous breast cancer

Symptoms of Breast Cancer

Breast cancer in its early stages does not result in any symptoms. However, some of the symptoms are –

  • Fluid coming out of the nipple can be green, bloody or clear to yellow. It can appear like pus
  • Lump in the armpit or breast lump which has uneven edges and hard. This lump usually does not result in any pain
  • Change in shape or size of the nipple or breast

Tenderness, breast lump and breast pain are some of the common symptoms of male breast cancer.

Advanced Breast Cancer Symptoms

  • Weight loss
  • Bone pain
  • Welling in the armpit
  • Skin ulcers
  • Discomfort or breast pain


  • OPD Consultations and Breast Cancer Screening
  • Mammography, Ultrasonography and MRI for Breast Cancer
  • Routine and Image guided FNAC and breast biopsies
  • Surgical Biopsies (Excisional Biopsy, Incisional Biopsy)
  • X-Ray Chest, CT, Bone Scans, PET CT for Staging work up
  • Receptor Tests
    • Estrogen and Progesterone receptor
    • Human epidermal growth factor type 2 receptor (HER2/neu)

Tumour Board Evaluation

Each and every breast cancer patient is evaluated by a special team of surgical oncologists, medical oncologists, Radiation Oncologists, Onco-pathologists and Imaging Specialists. Depending on the age, general condition, type of pathology and stage of the disease, a custom made treatment plan is charted out for each and every patient.

Breast Cancer Surgery

Surgeons provide individualized information and work with patients to help determine the appropriate treatment and provide timely surgical care. Surgical options for breast cancer treatment include:

Breast Conservative Surgery (BCS)

BCS is offered to patients to remove the cancer but not the breast. The following procedures can be done:-

Lumpectomy - Removal of the lump along with the margins of the surrounding normal breast tissue.

Partial Mastectomy - A segment of the breast which has cancer along with surrounding normal breast tissue is removed.

Other Types of Breast Surgeries

Mastectomy- is the surgical removal of a breast. Breast reconstruction is possible in many patients after the mastectomy.

Simple or total mastectomy- removal of the breast, with its skin and nipple, but no lymph nodes. In some cases, a separate sentinel node biopsy is performed to remove only the first level one to three axillary (armpit) lymph nodes.

Modified Radical mastectomy - removal of the complete affected breast with nipple/areolar region and lymph nodes. Breast reconstruction

Breast reconstruction after cancer surgery is an option for most women undergoing mastectomy. Surgical options may  include reconstruction with implants and autologous flap reconstruction (using the patient's own tissue), including:

  • TRAM surgery
  • DIEP surgery
  • SIEA surgery
  • Reconstruction of the nipple and areola

Axillary Node Dissection

Axillary node dissection, the surgical removal of the axillary (armpit) lymph nodes, is usually performed on patients with invasive cancers. A radical mastectomy, modified radical mastectomy, or lumpectomy operation often includes removal of axiliary lymph nodes.


Localization may be used to pinpoint the location of a breast tumor that appears on a mammogram but cannot be felt. In localization, a radiologist uses either mammography or ultrasound to insert a fine wire into the tumor site. The surgeon then follows the wire to locate and remove the targeted area.

As an alternative, a radioactive seed (a metal capsule that contains a small amount of radioactive material) the size of a grain of rice may be placed at the tumor site. The seed may be placed a day or more before the operation. The surgeon locates the seed with a handheld Geiger counter and removes the targeted area.

Frozen section analysis

Breast Cancer Specialists may use frozen section evaluation and intra-operative pathology consultations during breast cancer surgery to determine whether all of the cancer has been removed. Frozen sections ensure adequate clear margins during tumour resections. Frozen section also provide an intra-operative histological diagnosis where pre-operative evaluation may not have been done. Thus second surgeries with the attendant risks of anaesthesia are totally avoided and we are able to provide our patients with the best Surgical Oncology Services.

Evaluation of lymph nodes

If breast cancer is invasive (spreading into surrounding healthy tissue), it usually spreads first to the axillary lymph nodes in the axilla (armpit). When an invasive cancer is found in the breast, the surgeons remove axillary lymph nodes to confirm whether the cancer has spread.

Surgeons use several procedures to evaluate lymph nodes:

  • Fine-needle aspiration (removal of body tissue through a thin, hollow needle), which may be performed before surgery if lymph nodes appear abnormal on ultrasound
  • Sentinel lymph node biopsy is done for the majority of our patients with breast cancer, who are unlikely to have cancer in the lymph nodes
  • Dissection (surgical removal) of the axillary lymph nodes is performed when the cancer is known to have spread to the lymph nodes


Ductal Carcinoma In Situ (DCIS)

Treatment of ductal carcinoma in situ (DCIS) may include the following:

  • Breast-conserving surgery and radiation therapy with or without tamoxifen.
  • Total mastectomy with or without tamoxifen.
  • Breast-conserving surgery without radiation therapy.

Lobular Carcinoma In Situ (LCIS)

Treatment of lobular carcinoma in situ (LCIS) may include the following:

  • Biopsy to diagnose the LCIS followed by regular examinations and regular mammograms to find any changes as early as possible. This is called observation.
  • Tamoxifen to reduce the risk of developing breast cancer.
  • Bilateral prophylactic mastectomy. This treatment choice is sometimes used in women who have a high risk of getting breast cancer. We believe that this is a more aggressive treatment than is needed.

Stage I, Stage II, Stage IIIA, and Operable Stage IIIC Breast Cancer

Treatment of stage I, stage II, stage IIIA, and operable stage IIIC breast cancer may include the following:

  • Breast-conserving surgery to remove only the cancer and some surrounding breast tissue, followed by lymph node dissection and radiation therapy.
  • Modified radical mastectomy with or without breast reconstruction surgery.
  • Sentinel lymph node biopsy followed by surgery.

Adjuvant therapy (treatment given after surgery to increase the chances of a cure) may include the following:

  • Radiation therapy to the lymph nodes near the breast and to the chest wall after a modified radical mastectomy.
  • Systemic chemotherapy with or without hormone therapy.
  • Hormone therapy.
  • A clinical trial of trastuzumab (Herceptin) combined with systemic chemotherapy.
  • A clinical trial of bisphosphonates combined with chemotherapy and/or hormone therapy.

Stage IIIB and inoperable stage IIIC breast cancer

Treatment of stage IIIB and inoperable stage IIIC breast cancer may include the following:

  • Systemic chemotherapy.
  • Systemic chemotherapy followed by surgery (breast-conserving surgery or total mastectomy), with lymph node dissection followed by radiation therapy. Additional systemic therapy (chemotherapy, hormone therapy, or both) may be given.
  • Clinical trials testing new anticancer drugs, new drug combinations, and new ways of giving treatment.

Stage IV and metastatic breast cancer

Treatment of stage IV or metastatic breast cancer may include the following:

  • Hormone therapy and/or systemic chemotherapy with or without trastuzumab (Herceptin).
  • Tyrosine kinase inhibitor therapy with lapatinib combined with capecitabine.
  • Radiation therapy and/or surgery for relief of pain and other symptoms.
  • Bisphosphonate drugs to reduce bone disease and pain when cancer has spread to the bone.
  • Clinical trials testing new systemic chemotherapy and/or hormone therapy.
  • Clinical trials of new combinations of trastuzumab (Herceptin) with anticancer drugs.
  • Clinical trials of new combinations of lapatinib with anticancer drugs.
  • Clinical trials testing other approaches, including high-dose chemotherapy with stem cell transplant.


Medical Oncologists may recommend chemotherapy (treatment using drugs) following surgery to kill cancer cells that may have spread outside the breast. The drugs are usually administered intravenously (into a vein).

Chemotherapy may be recommended before surgery if the breast tumor is large, the lymph nodes are involved or the tumor is attached to the chest wall muscles or skin.

Chemotherapy may also be recommended in cases of inflammatory breast cancer.

Most patients receive chemotherapy after they have healed from the operation and before they receive radiation. We choose the chemotherapy drugs and sequence of treatment based on the details of each patient's tumor characteristics.


Radiation therapy involves the use of high-energy beams to kill cancer cells and shrink tumors. Patients who undergo radiation therapy consult with a radiation oncologist before treatment begins. Radiation may be recommended if:

  • Breast cancer treatment includes a Breast Conserving Surgery.
  • The invasive tumor is more than 5 centimeters in size at the time of the mastectomy
  • Many lymph nodes contain cancer cells


The term hormone therapy refers to the use of drugs that either block estrogen from reaching cancer breast cells or reduce the amount of estrogen produced by the body to reduce the risk of cancer recurrence.

  • Drugs such as tamoxifen or fulvestrant block estrogen from reaching breast cancer cells
  • Aromatase inhibitors reduce the amount of estrogen produced by the body.

Hormone therapy is most effective for patients whose tumor cells express (produce) the estrogen receptor. Hormone therapy is not recommended for patients who have tumors that are estrogen negative.

For premenopausal patients with tumors that are estrogen receptor or progesterone receptor positive (sensitive to hormones), medications or removal of the ovaries may also be recommended to prevent cancer recurrence.


Many targeted therapies, including lapatinib and trastuzumab or Herceptin therapy, which is often used to treat breast cancers that produce an abnormal amount of human epidermal growth factor receptor 2 (HER2neu) are also available. Targeted therapies offer the benefit of killing the specific target cells and hence, give better outcomes.
