What Does Chemotherapy Treatment for Breast Cancer Means?

The chemotherapy treatment for breast cancer involves using drugs to destroy cancer cells. Such drugs are given directly into the vein through a catheter or needle.

This treatment is used in combination with other treatment, like surgery, hormone or radiation therapy. With chemotherapy, it is possible to boost the chances of a cure, reduce the risk of returning of cancer, combat symptoms of cancer and help people live a longer and better quality of life.

Why is Chemotherapy Practiced?

After your surgery performed to remove a cancerous tumor from the breast, your doctor may suggest chemotherapy to destroy any unidentified cancer cells and to reduce the risk of recurrence of cancer. It is known as adjuvant chemotherapy.

The adjuvant chemotherapy is suggested when you have a higher risk of cancer spreading to other parts of the body or cancer recurring, even when there is no proof or evidence of cancer after surgery. The risks of metastasis are more when there are cancers cells present in the lymph nodes near the breast with the tumor.

When undergoing chemotherapy you must discuss with your doctor the level to which this process will reduce your chances of recurrence of cancer. Also, you must discuss with your doctor other alternatives, which might be effective in your situation.

Chemotherapy Process before Surgery to Cure Early Breast Cancer

In some cases, chemotherapy is offered before surgery, which is known as neoadjuvant therapy. This is practiced to shrink the larger tumors. This would:

  • Enable the surgeon to remove the tumor completely
  • Allow the surgeon to remove cancerous tumor and not just entire breast
  • Reduce the extent of ailment in lymph nodes, hence, enabling for less invasive lymph node surgery
  • Reduce the chances of recurrence of cancer
  • Allow evaluation of tumor response to therapy that helps enhance prognosis and the finest chemotherapy drug choice

The neoadjuvant chemotherapy process is often used for:

  • HER2-positive breast cancer
  • Inflammatory breast cancer
  • Larger tumors
  • High-grade tumors
  • Cancers which have spread to the lymph nodes
  • Triple-negative breast cancers

Performing Chemotherapy as the Primary Treatment to Cure Advanced Breast Cancer

If breast cancer has extended to other parts of the body and it is not possible to cure it through surgery, then chemotherapy can be used as a primary treatment. The experts can perform it in combination with targeted therapy.

The main aim of this treatment for advanced breast cancer is to enhance the length and quality of life rather than cure the ailment.

But there are certain risks associated with this treatment as the chemotherapy medicines travel throughout the body. The side effects depend on the drugs one receives and how the body reacts to it. These side effects may get worse during the treatment. Once the process is finished, most of the side effects temporary subside.

Short-Term Side Effects of Chemotherapy

In order targeting and destroying the rapidly increasing cancer cells, chemotherapy drugs can damage the fast-growing healthy cells too, like those present in the bone marrow, hair follicles, and digestive tract.

Numerous chemotherapy drugs can damage the nerve endings in your feet and hand, resulting in pain, tingling, burning, numbness, weakness in extremities, and sensitivity to heat or cold. Such side effects may go away after completion of the treatment.

Assessing the Potential Benefits of Chemotherapy

This treatment for breast cancer may not work well in all people. The doctor, therefore, analyzes a number of factors to determine whether chemotherapy must be able to benefit you or not. The higher risks of metastasis, the more likely it will benefit. Some of the common factors considered are:

  • Grade and Size of the Tumor – The bigger the tumor is and have a higher grade, the higher are chances of stray cancer cells. Hence, your doctor would suggest you chemotherapy.
  • Genetic Profile – For certain kinds of breast cancer like hormone receptor breast cancer, your doctor would do genetic testing of the tumor tissue to learn genetic makeup of the particular breast cancer. Such tests are known as prosigns, mammaprint, and Oncotype DX that would predict the risk of recurrence and how breast cancer would respond to chemotherapy.
  • Status of Lymph Node – The breast cancer cells present in lymph nodes are mainly treated with chemotherapy.
  • Age – A few studies suggest that breast cancer occurring at a young age is highly aggressive than breast cancer, which develops later in life. The doctors would suggest adjuvant chemotherapy when curing those diagnosed at a younger age to reduce the chances of cancer returning.
  • Hormonal Status – If the breast cancer is sensitive to hormones progesterone and estrogen, hormone therapy with estrogen blockers would be a better option for the adjuvant therapy.
  • HER2 Status – If the breast cancer releases too much growth-promoting protein called as HER2, the doctor would suggest chemotherapy and drugs, which specifically target this protein.
